WSJ general summary of N+I conference. [ASND VPN reference]

By MARK BOSLET
Dow Jones Newswires, 5/8/98

LAS VEGAS -- Two familiar themes dominated this week's networking
industry trade show here: producing gear that is faster and more powerful,
and giving it the capacity to do more.

Vendors attending the Networld+Interop conference rolled out powerful
switches, highlighted new network-management and security software, and
focused on the convergence of voice networks and computer networks.
They also talked up plans to bring more bandwidth to homes, even as
some Internet-service providers promoted tiers of higher-quality,
higher-priced access aimed at business customers.

As with other areas of technology, the networking industry is grappling
with rapid change. That's meant more choices for customers, but it's also
made it more challenging for network managers to sort through each wave
of new products.

At the same time, the Internet has altered the rather static traffic patterns of
mainframe and client-server networks, where users were grouped in
isolated, self-contained areas. Now, administrators have less control of
what users are doing and a greater need for oversight.

New Roles for Networks

"People are trying to get their infrastructures right" even as their networks
are pushed into a role of finding new customers and business opportunities,
said William T. O'Shea, president of business-communications systems at
Lucent Technologies Inc.

Among the hottest topics in the networking world is the prospect of
sending voice, data and video traffic across a single network, a cost-saving
opportunity highlighted by 3Com Corp. Chief Executive Eric Benhamou in
a well-attended keynote address. Mr. Benhamou described this
convergence as the "next major milestone for our industry," and his
sentiments were widely echoed.


It is the "hot topic right now" and a market that is "starting to happen,"
agreed Lucent's Mr. O'Shea. Systems to send voice, data and video
across a single network are here today, he said, but widespread use is yet
to come, and it will be two to three years before most customers adopt the
technology fully.


The customers participating in trials now are mostly larger corporations
acting as early adopters, said Edward L. Wadbrook, vice president of
product management at NBX Corp., a private start-up developing a
telephone-convergence product for small and medium-sized businesses.
Broader market deployment, he said, is a year or two away.

Gigabit Switches

Several interesting technologies discussed in past years have reached
market this year. Gigabit switches have been reaching the market over the
past several months, and network managers attending the show were
clearly moving to deploy them.

Among the high-powered boxes introduced at the show was a
eye-catching product from Fore Systems Inc. The Warrendale, Pa.,
company unveiled its ForeRunner ASX-4000, an asynchronous transfer
mode, or ATM, switch designed to sit at the heart of corporate networks
and run at an impressive 40 gigabits per second.

Another product area moving from talk to market is layer 3 switching, a
way of intelligently routing data using silicon chips instead of slower
software. Industry leaders such as Cisco Systems Inc., Bay Networks Inc.
and 3Com have been rushing these products to market.

Cisco officials said Tuesday that layer-3 switching should be a $2 billion
market by 2001.

Last year's drawing-board promises have also translated into more
sophisticated software and hardware for creating virtual private networks,
"tunnel-like" connections across private networks and the Internet that
provide better security and privacy for data communications.


From Smoke, Solutions

Where last year there was "smoke and arm-waving," this year there are
actual solutions, said Grace Carr, vice president of corporate marketing at
Bay Networks Inc. This year's products give service providers and
corporations the tools for easier, more sophisticated tunneling and for
more advanced monitoring of performance and security.

The market for virtual-private-network gear looks like a "rapidly growing"
one that should really take off in three to six months, Ms. Carr said -- and
market researchers see it quickly reaching at least $1 billion.

Both Bay and Ascend Communications Inc. introduced products for
virtual private networks at the show.


Bay brought out its Extranet Switch 1000, a product for companies with
up to 50 simultaneous remote or branch-office computer users who need
to link to a central network. The product incorporates modem functions,
security such as user authentication and abilities to manage the use of
bandwidth. At the show, Ascend introduced a broadened business
strategy for the market and software that provides network managers with
information on network performance.


Internet-service providers, meanwhile, are seeing more savvy customer
interest in higher-quality service, such as firewall, encryption and certificate
security for data transmission.

"The awareness level is at such a point now [that customers] are definitely
more sophisticated," said Scott G. Lewis, Internet-product manager at
CompuServe, a unit of WorldCom Inc.

Industry leaders, of course, also worked to drum up interest in next year's
technologies. Talk focused on the greater use of fiber optics in network
backbones and on the evolutionary step to switching at layer 4, where, for
example, a CEO's e-mail can be given a higher delivery priority than e-mail
from accounting.


Today, however, sorting through the array of products and competing
claims remains a time-consuming task for customers. "There is so much
technology...thrown at them," said Bay's Ms. Carr.

VPNs Branch Out To Play New Roles
[I like the reference to VPN as a virtual LAN. Is this a backdoor way for ASND to enter LAN?? Comments would be appreciated. djane]

By SALVATORE SALAMONE, Friday, May 8, 1998, 5:30 p.m. ET.

techweb.cmp.com

Las Vegas -- Think outside the box.

That's what many IT managers are doing when
it comes to applications of virtual private
networking technology.

VPN pilot tests and those handling live traffic
are giving IT managers confidence that VPNs
do indeed provide adequate security and
acceptable levels of performance. With this
confidence, they are now looking at ways to
apply VPN technology to other network
applications.

At the NetWorld+Interop trade show here,
the first iterations of these new VPN
applications started to emerge.

Companies have typically looked to VPNs for
three main applications: outsourcing remote
access, connecting sites over the Internet and
linking outside users on an extranet.

But several other applications are now coming
into focus. They include using VPN
functionality within an intranet, securing a
variety of communications, and carrying
different types of traffic, including voice calls
and SNA data.

Infonetics Research Inc. has just completed a
study of user plans for VPN products and
services. One of the key findings: About half
the respondents who are using VPNs plan to
use them to segment groups on a corporate
intranet, similar to what many vendors and
users refer to as virtual LANs, according to
Michael Howard, Infonetics' CEO.


Essentially, this offers levels of segmentation
on an intranet that are otherwise only
achievable using routers or Layer 3 switches.
And, some industry experts said, the VPN
approach may be much easier to manage and
administer than these alternatives.
[Nice potential for ASND]

Another application discussed at the show
was the use of VPN technology to secure
Web hosting information. For example,
Concentric Network Corp. introduced
ConcentricHost, a managed Web-hosting
service. The company offers the service by
itself but also combines managed hosting with
its VPN services. This combination would
allow a company to use Concentric's
backbone as the heart of its intranet while
knowing that the hosted data would only be
available to employees, for example. And, on
top of that, the data would only be available to
employees who are entitled to see it.

There also were discussions of using VPN
technology to secure other forms of
communications. "You can do secure
videoconferencing using NetMeeting, for
example," said David Dawson, president and
CEO of V-One Corp.

"VPNs can be used to secure IP voice and
fax, too,"
said Robert Wilson, president and
CEO of Assured Digital Inc., a VPN vendor.
Indeed, Infonetics found that people wanting
to buy a multifunction VPN box--one that
might include firewall, authentication and
routing functions, for example--wanted VPN
connections to handle other types of
applications.

Thirty-three percent of respondents to the
Infonetics survey are interested in using VPNs
for voice over IP, Howard said.


These nontraditional VPN applications take
advantage of IT managers' increasing comfort
level with VPN security to offer alternative
ways to meet the communications needs of
organizations.

"We've been evaluating VPN technology to
connect sites, and security is the first issue
everyone raises," said Robin Hall, a network
administrator at the law firm of Reed, Hapner
and Selwin. "I've been able to convince
people here that encryption technologies like
triple-DES are adequate for safeguarding the
files and data that we expect to run over a
VPN."

Her company also is evaluating voice-over-IP
equipment so that lawyers in different sites
could talk over an IP network, thereby saving
toll charges. "The security that comes with a
VPN seems like it lends itself to other
applications like voice over IP."

And in a related development at N+I, IBM
discussed ways to handle time-sensitive SNA
traffic using VPNs. Some IT managers are
uncomfortable with the idea of using VPNs to
carry SNA traffic because of perceptions that
VPNs do not offer the performance needed to
handle such data.

IBM is trying to address this issue in a number
of ways. On one hand, it announced that it is
adding IPsec support to increase the IP
security features of its Nways internetworking
hardware equipment line that includes the
3746 Multiaccess Enclosure and 2210 and
2216 routers.

To address performance issues, the heart of
the IBM effort is providing a way to tag VPN
data carrying SNA traffic and then making
sure that the internetworking hardware is
intelligent enough to assign a high priority to
this traffic.

5/4/98 Telepath article. Discusses changes in RBOC procurement policies. Very favorable for companies like ASND, e.g., Bell Atlantic

"Measuring up in a whole new market. Rigid old procurement policies give way to faster, more flexible purchasing patterns"

pubs.cmpnet.com

By Alan S. Kay

May 4, 1998
.......

Not that long ago, there was little point in asking about relationships
between telephone companies and equipment vendors. After, all AT&T and
the Bell companies dominated the industry and bought virtually all of their
equipment from Western Electric, a sister company.

Things have changed a lot since you could have a dial phone in any color you
wanted so long as it was black. In the decade and a half since the government
broke up the Bell system, the telecom marketplace has fragmented, with a
confusing array of new service providers-CLECs, ILECs, IXCs, CAPs,
ISPs-battling for share in markets that until recently were barely more than
futurists' visions. And a host of new equipment suppliers have sprung up to
serve those new carriers as well as the traditional service providers.

But telecommunications is not like other new marketplaces. The hallmark of
the voice telephone system is reliability: One of the touchstones of the public
switched telephone network is that the dial tone will always be there.

To preserve that reputation, local carriers and long-distance companies must
temper their desire for cutting-edge, cost-effective equipment, much of which
is new and unproven, by imposing some old, familiar-but expensive and
time-consuming-requirements to meet traditional central-office equipment
standards.

But expensive and time-consuming are not advantages in the age of the
Internet and new competition. "Smaller, newer companies are much more
adaptable to new technologies and innovative ways to get technologies out
quicker," said Buzz Schadel, vice president of corporate marketing for
eFusion Inc., a Beaverton, Ore., Internet telephony vendor. "The reason you
see alternative carriers like WorldCom growing so much is that these newer
upstarts are much more flexible."


"With their brands and their facilities-based infrastructure, the traditional
players are so slow to move," said Kelly McGovern, vice president for
Internet and telecom marketing at Bay Networks Inc., in Santa Clara, Calif.
"They're surfing this voice wave, and things are looking good. But there's this
rock under there-and that's the emerging carriers."

The issue of how to introduce equipment from new vendors into central
offices is far broader than just new competition, though; it also involves the
development of new data-oriented markets. These are markets in which
traditional carriers, both local and long distance, want to compete.

There's certainly no shortage of hardware and software vendors ready to sell
data-oriented gear to service those markets to Bell companies and other
established carriers. But the culture of provisioning the telephone central office
isn't one that's historically been very open to new technologies and to young,
untested companies.

That may not be much of a problem for established voice carriers, at least not
right now, according to one analyst. "One of the things I think it is crucial to
understand," said Tom Nolle, president of CIMI Corp., a telecom
consultancy in Voorhees, N.J., "is that this 'rapidly changing marketplace' is
not changing all that rapidly. Voice networking or traditional networking
accounts for 90 percent of the revenues of the common carriers.
Institutionally, they are fixated on a level of service, quality and reliability we
have come to expect."

In carrier voice networks, quality of service is maintained largely through
adherence to standard procedures and equipment specifications. Key is the
Network Equipment-Building System(NEBS), a set of hardware
requirements intended to ensure that equipment is designed efficiently and
operates reliably. The NEBS standards, originally established in the 1970s by
Bell Labs, define a set of spatial, environmental and safety requirements for
equipment to be used in central offices and other telephone buildings.

NEBS certification is a lengthy, costly process. According to Crystal Group
Inc., a Hiawatha, Iowa, company that manufactures computers for telephony
use, obtaining NEBS certification can cost an equipment manufacturer
upwards of $100,000 per piece of equipment tested. The cost of this
certification typically is passed on to the buyer, making NEBS-compliant
equipment significantly more expensive than comparable commercial
equipment.

To challenge that mind-set, incumbent carriers may well need to turn to
young, small, venture-backed companies, many of which may not yet have
track records in shipping products. Historically, that would have been a
problem for companies that descended from Ma Bell. But Mr. Nolle said that
won't be a problem in the future-so long as the equipment isn't going into the
central office.

"If the carrier community is presented with a combination of a clear service
opportunity and products that are noticeably superior in supporting that
opportunity, the carrier community will buy them, regardless of the pedigree
of the vendor," he said. "The carrier community will certainly value experience
if the features and other characteristics are equal. But where no comparable
capability is available, they will buy from the new player."

Mr. Nolle suggested that carriers will increasingly begin to segregate their
facilities, creating data-networking centers in locations physically separate
from voice-telephony central offices and provisioning those data sites with
less expensive, commercial-grade equipment.


That's a widely shared vision of the future-one in which data connectivity
services are provided by a wide range of carriers and service providers. For
the new competitive carriers-those without local dial-tone
responsibility-NEBS compliance will be an issue only if they choose it to be.
Given the nature of the competitive environment, that's not very likely, at least
in the case of enhanced and data transmission services.

In fact, vendors report that competitive local exchange carriers (CLECs) and
Internet service providers are buying enterprise-grade routers, switches and
other networking equipment rather than telco-style equipment.


"Think about some of the larger national Internet-backbone providers. Many
of them service their Internet access customers out of real estate that isn't the
traditional central-office-based environment," said Marilyn Suey, marketing
vice president at Assured Access Technology Inc., a young Milpitas, Calif.,
manufacturer of high-density switches. "It's more like a computer
environment. There, environmental and safety requirements aren't as stringent
as they are at the NEBS3 level."

Service providers aren't reneging on their commitment to high availability, said
Mr. Schadel of eFusion; they're finding other, less expensive ways to deliver
it, such as a network of systems that operate in immediate failover mode.

"I like lots of little boxes," said Marc Evans, chief technology officer at The
Destek Group Inc., a Nashua, N.H., company that provides WAN
connectivity to businesses and institutions. "If I'm only deploying one or two
pieces of gear, I'm taking a risk with computer-grade gear. But if I'm
deploying many of them, do I really care if a small percentage of the overall
equipment fails?"

Money, in particular the cost of equipment, is a significant issue for service
providers. Mr. Evans said a big price differential can help vendors build
reliability into systems by using additional equipment and by having spares on
hand. He said he evaluates computer-grade equipment on the job to
determine its behavior and reliability, and then he shops for price. "If I save
50 percent, it's a heck of an incentive," he said.

Ironically, the purchasing and decision-making styles of the large, established
telephone companies and the new competitive carriers appear to be
converging. ISPs and CLECs are becoming more structured in their
purchasing processes as they grow, according to equipment vendors.

Said Joe Furgerson, director of marketing at Juniper Networks Inc., a
Mountain View, Calif., vendor of Internet hardware and software: "These
people are managing huge networks. There's certainly a lot in the lineage of
the telcos to be learned: You do have to proceduralize things because, if you
don't, you're dealing with so many people across so many functions that your
network operational performance can get compromised."

Some vendors, who didn't want to be identified, said the Bell companies are
having a hard time with the rapid growth of the Internet. "They can't deal with
it," said one. "It's not voice but data, it's fast moving and it requires some
bend."


Nonetheless, things are changing rapidly. While many critics have argued that
the hidebound bureaucracies of the Bell companies wouldn't-or
couldn't-change until the generation of managers who learned the business in
the old Bell system had been supplanted, recent developments suggest the
shift is already occurring. For example, many of the Bell companies have
created nonregulated business entities to market lower-margin but
fast-growing data services.

U S West Enterprise Networking has made the cultural shift necessary
to allow it to be quicker in the marketplace, according to Mike Sapien,
vice president for market development. Emblematic of that, he said, is its
positioning of its data-oriented business. "Six years ago, when Enterprise was
started, the whole data business was a small boutique business within U S
West. The difference now is that we have become more of a heartbeat of U S
West, focused on the data movement we need to make and the Internet
space we're going toward."

Changing gears

As part of that shift, the company's purchasing philosophy and management
attitudes toward it have changed as well. Where once every purchase
required a request for proposal and a formal evaluation, testing and approval
process, time-to-market concerns have led to a softening of that bureaucratic
resolve.

U S West is trying to speed up the process by taking new approaches. The
company has established a strategic relationship with Cisco Systems Inc. and
is relying on Cisco to bring in other technologies that will get U S West closer
to the IP world more quickly. This approach, Mr. Sapien said, reflects a new
pattern of alliances with vendors rather than just purchasing relationships.


There's also more room for newer and smaller companies to sell to U S
West, although one of the best ways for that to happen is through Cisco as a
partner. Helping that development, Mr. Sapien said, is a shift in U S West's
attitudes toward standards compliance. The company is showing "a little more
tolerance" for some variance in compliance with standards such as NEBS for
central-office equipment. At the same time, he said there is a pattern
developing of placing nonvoice equipment in a corner or another room so
they're technically not in the central office and therefore need not comply with
NEBS.

One of the most radical shifts in Bell company procurement patterns is to be
found at Bell Atlantic.
Ethelyn Katz and Teresa Carroll, director and vice
president of corporate sourcing, respectively, said the company has created a
new purchasing structure that mirrors the segmentation of the markets Bell
Atlantic competes in, rather than its internal bureaucracy.

The team approach

Bell Atlantic now pursues its sourcing needs with suppliers using 11 teams of
sourcing and technology professionals that manage market segment purchases
regardless of what business unit that technology is for.
It is, Ms. Katz said, a
"very flat" organizational structure.

"We're now defining needs across the entire organization. Those needs are
then taken to the marketplace by corporate sourcing," she said. The teams
represent the stakeholders seeking the acquisition and are empowered to
choose products and make the buy on behalf of the company.

The change allows Bell Atlantic to buy current technology as needed to suit
the company's target market positioning, rather than having to tailor
purchasing decisions to decades-old standards, the two said. That doesn't
mean relaxed standards, but rather clarified ones, they added.

What does this mean for Bell Atlantic's willingness and ability to buy from
nontraditional vendors?
"Our new approach allows us to say to the
marketplace that we will consider all possible suppliers," Ms. Carroll said.
"All you need to do is tell us what you're about and how you will meet our
needs."

Assessment of those suppliers, she said, is now done on an
acquisition-by-acquisition basis. "Our source-process leaders are out in the
marketplace every day, finding out what's going on. And part of the
empowerment of the team is to look at suppliers for another way to do things.
If it will bring value to Bell Atlantic, we should always be open to changing the
specs, for example," Ms. Carroll said.

Can a new purchasing structure change a Bell company into an agile
competitor in new markets? That assertion is, understandably, greeted with
some skepticism among telecom veterans. But it does seem clear that the new
competitive marketplace, both for the new players it involves and for the
pressures it has placed on existing carriers, has opened the door far wider for
a new generation of vendors to enter.

5/8/98 Wirbel article. Internet Protocol gets rules for good behavior

By Loring Wirbel with additional reporting by Rick Boyd-Merritt
Posted: 11:45 p.m., EST, 5/8/98

pubs.cmpnet.com

ATLANTA - Now that it seems the Internet Protocol is
everywhere, designers of systems that span the gamut from cable
modems to wide-area network switches are finding it's time the
protocol actually grew up and became manageable. At the
NetWorld+Interop show in Las Vegas and at Cable '98 in Atlanta,
internetworking specialists and cable-TV operators hammered out
mechanisms to create controllable networks from a protocol
designed for connectionless traffic.

Powerful business interests in both public and private networks are
driving the demand for well-defined quality-of-service (QoS)
features for prioritizing IP flows in ways similar to what's possible
with connection-oriented asynchronous transfer mode (ATM). But
substantial engineering challenges still stand in the way.

In the private networking arena, "the most significant technical
trend I see is the application of policies, classes and qualities of
service to networking,"
said Daniel Pitt, director of the Bay
Architecture Lab at Bay Networks Inc. (Santa Clara, Calif.). "This
is how a company will translate its business needs into its systems.
But the industry has not made enough progress in translating
quality-of-service into realizable architectures and products."

Among service providers, "ISPs are desperate to find a way to
make more money," said Gordon Saussy, vice president of
marketing for Torrent Networking Technologies Corp. (Silver
Spring, Md.). "They need to find a way to sell first-class seats and
get out of the business of selling flat-rate services. Fine-grained
quality-of-service is their way to [do] that."

Rob Glaser, chief executive of RealNetworks Inc. (Seattle), made
QoS a central theme in his Thursday N+I keynote, boiling down
the issue to consumer expectations. Glaser noted that the new
RealSystem G2 Internet multimedia player will implement a new
smart streaming feature, which will scale down the player's
bandwidth and performance at times of network congestion rather
than halt video or audio streams when too many packets clog the
Net. He advised paying close attention to a new standard, the
Synchronized Multimedia Integration Language (SMIL), which he
called an HTML equivalent for linking multimedia objects to the
Real Time Streaming Protocol.

Since different network managers have different goals for QoS,
methods vary widely for assigning service classes to IP. Some
managers seek only to preserve mission-critical, time-sensitive
mainframe applications. Others want IP quality-of-service to
include explicit support for low-latency isochronous traffic, such as
voice and video.

Finding solutions to the former problem would bring network
managers a step closer to true policy-based network
configurations. The latter requirements would provide better
support for voice-over-IP, the holy grail among providers ranging
from competitive local-exchange carriers to cable-TV multi-system
operators.
Solutions for Internet QoS range from the all-software
traffic shapers offered by CheckPoint Software Solutions Inc. to
the dedicated hardware offered by Packeteer Inc. and the totally
new architecture promoted by IP Highway Inc.

In any event, providing an efficient solution set for IP QoS
promises potentially big returns. Cisco Systems Inc. last week
acquired one such provider, Class Data Systems Inc. (Ra'anana,
Israel), for $50 million in Class B stock. And IP Highway, the
Israeli company's closest competitor, experienced some of the
heaviest traffic at N+I's Startup City.


Cisco plans to integrate the Class Data prioritizer into its own
Assure initiative for applications-based networking. First releases
of the integrated software will only handle mission-critical business
applications, though Cisco and Class both pledged eventual
support for isochronous services.

While Class Data has been exploring point solutions, newcomer IP
Highway (San Jose) has developed an end-to-end scheme based
on a new enterprise architecture. A QoS Management Server
oversees clusters of Policy Servers and QoS Generators. Policy
Servers sit at the edge of the WAN and determine enterprise
policy for handling traffic from outside. The QoS Generator is the
machine that actually assigns QoS parameters for IP flows.

IP Highway chief technical officer Shai Herzog said implementing
the topology would let end users keep all their legacy hardware
and software yet have traffic provisioned from the server with full
QoS signaling.

At Packeteer, developers are working to hardwire or provide in
firmware pre-standard QoS methods that are somewhat specific to
network topologies. Last week, Packeteer released an enterprise
version of the software for its bandwidth shaper, as well as a
version specific to Cisco networks. The latter leverages Cisco's
algorithms for tag switching, weighted fair queuing and weighted
random early detect.

The Packeteer software has also been made Java- and
object-module-aware. Marketing vice president Bob Quillin said
support for real-time services may be possible in the future but
called effective traffic shaping with non-real-time traffic the larger
challenge.

Designers also worry that work on quality-of-service could
mushroom into a new IP bottleneck. "One problem is how to
reduce or eliminate the amount of flow-by-flow state information in
the core of the network," said Bay's Pitt.

Since ATM began as a connection-oriented packet switching
standard based on identically sized cells, and it's ironic that
advocates of connectionless IP are embracing QoS concepts that
they once rejected in ATM as too complex. "QoS for IP can turn
IP into a protocol at least as complex as ATM,"
said Gary
Mading, market-development manager for ATM products for
Motorola Semiconductor Products Sector (Plano, Texas).

View from TV
Yet the National Cable Television Association's Cable '98 show
put out the call for advanced IP QoS parameters that would make
prioritization for voice, video, and data traffic over IP finer-grained
than the ATM equivalent. The standards efforts operate on at least
two levels in the Open System Interconnect protocol stack.

Broadcom Corp. (Irvine, Calif.) and Bay Networks (Billerica,
Mass.) have devised a packet-fragmentation scheme, operating on
the media-access-control (MAC) layer of a cable-modem design,
that will be incorporated into Release 1.1 of the Data Over Cable
System Interface Spec (Docsis) developed by Cable Labs.
Broadcom already supports the fragmentation features in a new
MAC device for cable modems. But marketing vice president Tim
Lindenfelser said that as a Docsis standard, the fragmentation
scheme will be open to any chip vendor wishing to implement it.

Ethernet packets can be split at the home interface into equally
sized cells of 16 kbytes to 256 kbytes, and various priorities can
be set for for variable, unspecified and best-effort bit rates. For
voice services' continuous-bit-rate traffic, the fragmentation scheme
assigns packets to what Broadcom calls a directed-grant service.

Gerry White, chief technical officer of Bay Networks' broadband
technology division, said the company was excited enough about
Broadcom's proposal to be a cosponsor for the Docsis specs. But
he added that Bay also saw a need for transport-layer mapping of
IP flows to packet fragments. It thus partnered with 3Com Corp.
and American Internet Inc. to promote a QoS Working Group
within the Multimedia Cable Network Systems group working on
Docsis. That group now is addressing network- and
transport-layer schemes for QoS mapping to the new
packet-signaling method.

LCP modems, too
Meanwhile, Bay Networks is taking its vision of enhanced IP
functions a step further by implementing voice-over-IP and
virtual-private-network (VPN) functions in the former LANcity's
LCP modems while adding centralized IP-security functions
through the Extranet switch, to which it gained access when it
acquired New Oak Communications Inc. late last year. While
telephony and Internet access groups are the first within Bay to
make use of the Extranet switch, White said, new members of the
family, such as Extranet 1000, are suited for use as front ends to
cable multi-system operators' headends. End-to-end networks can
be implemented using QoS over IP.

Advanced IP services played a role in several large cable-modem
contracts announced at the show. France Telecom will offer an
alternative to the character-based Minitel service through a
cable-modem infrastructure put together by Philips Broadband
Networks using modems from Com21 Inc. Buck Gee, vice
president of marketing at Com21, said the company will leverage
voice-compression cards and packetization schemes for
voice-over-IP to follow up its initial products for the France
Telecom contract with next-generation modems that will enable
more IP features.

Advanced IP service also factored into Tele-Communications Inc.
subsidiary TCI.Net's decision to award 3Com Corp., Bay
Networks Inc. and Thomson Electronics a contract to supply cable
modems for its Internet services. Rob Davenport, chief operating
officer, said TCI.Net wants to offer voice and video over IP by
summer 1999 and to add VPN-like features within a year after
that.

Similar motivations drove Shaw Communications (Calgary,
Alberta) to buy 40,000 modems and related headend equipment
from Terayon Corp. (Santa Clara, Calif.) and to make a $7.5
million equity stake in Terayon.

They may indeed deserve a high valuation.
