Hi djane - Grubman says voice over IP is a waster of fiber capacity. If so, is Cisco pursuing the wrong strategy? They seem to be pushing data, voice, video integration over IP. They may be betting on the wrong horse.

<<... Grubman, a managing director of Salomon Smith Barney, who heads that firm's global telecom team...

".. all this mumbo-jumbo means is that data
networks carry much more mission-critical stuff than voice networks. If you
and I are conversing and the line goes dead, okay, fine, we'll call back. But if
you're running someone's global data network around the world -- for money
transfers, foreign-exchange reconciliations, inventory transfers and the like -- a
line going dead is a very big problem.
In 1996, when MFS bought UUNet, virtually 100% of UUNet's commercial
customers were connected to it with a T-1 line that handles 1.5 megabits of
transmission. Today, probably 33% of new customers signing up with UUNet
want OC-12 lines, which offer 36 times as much capacity. All this has
occurred in less than two years.
My point is, demand for bandwidth, fatter pipes if you will, keeps going up
and up and up from corporations around the world. Therefore, to be perfectly
blunt, voice over IP is a waste of fiber capacity. It's a little niche business that
will remain that way. And I bet that providers of voice over IP will be forced
to pay access fees to local phone companies within 18 months.
Castro: Let me add something. Outside the U.S., especially in Europe,
incumbents are the biggest providers of Internet access in general, and will be
the natural providers of IP telephony. They're not doing it now because it
doesn't make any sense.">>

real mumbo-jumbo ---
- voice call going dead is very grave concern and voice networks are built for very high availability; imagine dialing 911 and the call going dead all the time; this is life-and-death situation and much much more serious stuff compared to a mere billion$$ of paper floating around on the line.

- to bluntly state - VoIP, VoFR, VoATM and Voice over proprietary protocols had and still being used very much in the Enterprise networks bypassing telco since many moons ago -

right, does not make sense totally, mumbo jumbo ..

BusinessWeek article. FINALLY, EUROPEANS ARE STORMING THE NET

The region looks like the next great cyberspace growth market

businessweek.com@@T2p2ZWQAkK8OKwAA/premium/19/b3577085.htm

It's 8:58 p.m., and from Berlin to Munich to tiny Black Forest hamlets, German
Internauts are booting up their PCs. Their chat rooms have been practically
deserted until now. But after the two minutes it takes to make modem
connections, they will be as lively as Bavarian beer halls. ''There's a tremendous
surge of online activity at nine o'clock in Germany,'' says Jack Davies, president
of AOL International. Why so? It's at 9 p.m. that German phone rates drop by
half.

Europeans, long cyberspace holdouts, are rushing onto the Net. It started with
companies, from German auto giants to banks in the City of London, that are
wiring together customers and suppliers in networks. With appetites whetted,
employees are subscribing in increasing numbers to online services, which are
hurrying to come up with offerings in European languages. Net subscriptions in
Europe are growing at 30% annually, even though high rates push up the average
outlay to $75 a month--triple a U.S. rate that allows unlimited Internet access on
free local lines.

Europe, in short, looks like the next growth market for cyberspace. If
deregulation cuts prices, as expected, cheaper phones--or cable or satellite
connections that circumvent phones--should draw consumers online. The most
dramatic growth is likely to be in company-to-company electronic commerce.
Forrester Research, a U.S. technology researcher with a unit in Amsterdam,
predicts that online business of $1.2 billion this year will be worth $64.4 billion by
2001. ''There's incredible pent-up demand,'' says James Richardson, president of
Cisco Systems Inc.'s European operations.


Internet companies are rushing into the fray. Partnered with German media giant
Bertelsmann since 1995, AOL is taking on giants Deutsche Telekom and France
Telecom. When AOL purchased CompuServe Inc. in February, it nearly doubled
its European base, to 2 million. In the race to wire the Continent for the Net,
outfits such as Cisco and Lucent Technologies are battling France's Alcatel and
Germany's Siemens.
What's more, as Europe's businesses invest some $125
billion to prepare computers for the euro, they're also putting the businesses
online. For Casa Gancia, a 150-year-old Italian winemaker, the Internet replaces
annual communications traffic of 35,000 faxes and letters between its offices,
warehouses, and agents. It is now extending the network to 60 countries.

SKIP A STAGE. In both home and business applications, analysts estimate,
Europe is about four years behind the U.S. in cyberspace. In Germany, France,
and Britain, barely a fifth of homes have PCs, while in the U.S., the figure is
nearer half. Internet usage is still just 7% in Germany, 6% in Britain, and 2% in
France, compared with 25% in the U.S.
But Europe could catch up fast. It may
not have to follow the U.S. through a step-by-step evolution of chips and
modems, for instance. Instead, Europeans can buy their way into the state of the
art. ''To some extent, Europeans will move faster because they don't have to go
through the pioneer stage,'' says William A. Etherington, general manager of
IBM's Europe division.

In fact, many Europeans may skip the PC stage and jump to the Web through
alternative devices. Alcatel wowed the crowd at Germany's Cebit computer
show last March with a telephone equipped with a screen and built for
Web-surfing. L.M. Ericsson and Nokia Corp. are promoting their latest cellular
phones as Web machines.

For many Europeans, though, the most likely path to the Net is the old telly.
British Telecommunications PLC, which has teamed up with Microsoft Corp.'s
WebTV, predicts that TV access to the Internet in Britain will grow from zero
now to 3.5 million subscribers in four years. That's twice the number of current
Net surfers using PCs. Cable & Wireless Communications PLC has hooked up
with U.S.-based Network Computer Inc., an Oracle and Netscape
Communications affiliate, for its autumn, 1998, digital TV launch. C&W intends
to offer TV-based Internet access within the next 12 months.

EASY TO WIRE. Even as consumers sort through these choices, businesses are
pressing ahead. Multinationals have been moving online for the past five years. In
April, Amazon.com, the online bookseller, announced that it would purchase
three European companies--two in Britain, one in Germany--to build European
book and video sales. And to compete in a united Europe, small companies have
to catch up. Further, many of them are adopting software systems--including
products by Oracle, Baan, and SAP--that virtually thrust them into networks.

One added benefit for businesses: They're the first beneficiaries of telecom
reform. Throughout the Continent, new competitors are targeting business
customers with discount services. Businesses are easier to wire and provide far
greater traffic than the unwieldy consumer market. ''You get to business
customers with a much smaller investment,'' says Aldo Peterson, chief executive
at Telepartner, a Danish company that discounts phone services.

The trouble for consumers is that while many former monopolies, including
Spain's Telefonica, are lowering long-distance fares, they're compensating by
jacking up local rates. ''There has to be a balance,'' says Luis Lopez von Damm,
CEO of Telefonica Internacional, the company's European joint venture with
WorldCom Inc. In the meantime, prices limit the number of Net surfers in some
countries.

Europeans have long resisted the Internet as a phenomenon of limited value.
Now, as they warm to the Net, they're likely to imprint their culture--as well as
their languages--on cyberspace. And with time, maybe they won't have to wait
until 9 p.m. to switch on.

Dawley in London

<<Excerpt on ISP benefit from VoIP:

Jack B. Grubman, a managing director of Salomon Smith Barney, who heads that firm's
global telecom team.

......
Q: How's the quality of Internet telephony?
Grubman: When you make a regular circuit-switch call, you use a dedicated
circuit. When you send any kind of message over routers, which happens on
the Internet, there's no network management, no queuing. A bunch of data hits
the routers. The data go off on their merry way, looking for their destination.
The problem is, the data may not arrive the way they were sent.

Q: Please elaborate.
Grubman: Let's say you send five packets of
data. Each packet goes looking for a path. They
all do arrive at the destination point, but the third
packet may get there before the first one does.

Q: How much sooner?
Grubman: We're talking seconds. That's okay
for data, meaning numbers, but not okay for
voice. It needs to be recompiled in milliseconds or
fractions of milliseconds. That's why you have a
delay on voice over IP. You can't have full duplex conversation, meaning you
can't both talk at once. You'll never hear voice over IP with quite the same
total quality and lack of delay as you get on circuit switches.
Again, if the entire cost advantage of voice over IP is a lack of access
charges, we know that advantage will disappear one way or another. In the
developed world, I don't view voice over IP as being that much of a threat.
There's another factor here.>>>

packets can get out of sequence and delay are part of connection-less IP and UDP attributes; it's a common simple networking technology knowledge (every networkers have) is that to have proper QoS over this type of network requires additional control (resource reservation, load control. .. protocols).
