Xedia First To Deliver ATM Access With IP Quality of Service
PR Newswire - January 26, 1998 09:18
An Open IP QOS Solution That Can Be Deployed Today
LITTLETON, Mass., Jan. 26 /PRNewswire/ -- Xedia Corporation, leading
provider of IP Quality of Service solutions enabling business class Internet
services, today announced Access Point/ATM as the first Internet access
product to bring Quality of Service (QOS) control to IP-over-ATM network
service offerings. With Access Point/ATM, Network Service Providers (NSPs)
can now offer a new generation of high speed Intranet and Extranet services
that deliver scaleable ATM bandwidth with the IP service level commitments
required by their business customers. NSPs can also deploy Access Point/ATM
as part of their regional access infrastructure to provide service level and
wide area cost control over wide area links leading from Points of Presence
(POP) into the Internet backbone.
"ATM access solutions are now being deployed to more quickly provision
broadband rate services for Internet access customers. These high bandwidth
customers are well down the path of migrating key business applications to the
Internet, and policy-based QOS control is critical to meeting their internal
business objectives. Access Point/ATM is the first standards-based solution
to meet explicit IP application service level commitments while taking
advantage of the bandwidth scale provided by ATM," said Karen Barton, VP
Marketing of Xedia.
"Previous IP-over-ATM offerings have been best effort solutions," said
Paul Koning, Xedia's ATM architect and past chairperson of the ATM Forum PNNI
Working Group. "Xedia is the first to deliver a solution that is standards-
based and does not require changes to network applications. Access Point/ATM
QOS control is provided with Xedia's Class Based Queuing (CBQ), which delivers
a very flexible and scaleable IP Layer traffic shaping and control service to
complement high speed ATM bandwidth services."
An IP QOS Solution Today -- With Standards, Scale, And Flexibility ATM has
long been positioned as the QOS technology of choice. However, ATM QOS
operates at Layer 2, with control exercised on a per virtual circuit basis.
The challenge in bringing IP LAN traffic and ATM together has been in how to
make ATM QOS services available to the IP applications running over these
virtual circuits.
The standards community has focused on RSVP as the recommended solution.
More recently, there have been concerns associated with RSVP. First, an RSVP
solution requires changes to user applications. In addition, mapping RSVP
service requests into ATM is not straightforward, and standards progress is
slow. But, most importantly, RSVP assumes control is managed from the IP
application.
"In the end, RSVP has the affect of placing QOS control into the hands
of network users rather than network administrators," said Koning. "The loss
of control that comes with application-enabled RSVP, inherent RSVP scale
issues, and incomplete RSVP standards work have created the need for an
alternative solution that can be deployed today."
Xedia's Access Point/ATM product features a standards-compliant RFC
1577 Classical IP and ARP over ATM implementation with the unique added value
of IP layer QOS. The IP-over-ATM RFC specifically defines a best effort
service, and efforts to extend that service definition are in the early
stages. As a result, solutions to date have been either best effort, or in a
few cases, based on simple priority schemes.
Xedia delivers QOS with Class Based Queuing (CBQ), an open, and highly
flexible solution for classifying user traffic and then meeting explicit
bandwidth commitments across a range of IP applications, users, and flows.
Because control is applied at the IP layer, or Layer 3, CBQ does not depend on
any Layer 2 specific traffic management mechanisms. As a result, it fits
easily into existing networks and provides a consistent model for QOS control,
regardless of whether the underlying Layer 2 technology is Frame Relay, ATM,
Ethernet, or PPP.
Broadest Family of Access Quality of Service Products
Access Point/ATM joins Xedia's family of next generation Internet access
products, purpose-built to migrate best effort IP networks to committed
service level environments supporting business class application needs.
Xedia's Access Point 10 and Access Point 100 are LAN-to-LAN products
providing the bandwidth control, measurement, and monitoring required to meet
service level contracts across managed server environments or routed backbone
networks. Access Point 45 and Access Point/ATM are LAN-to-WAN platforms
providing broadband WAN connectivity with the high performance bandwidth
control and usage monitoring required for emerging business class Internet
access needs.
Pricing and Availability
Xedia will offer two different members of the Access Point/ATM product
family. The Access Point/ATM-DS3 will include a 10/100Mbps Ethernet and ATM
DS3 interface, and will be available in 30 days at a price of $19,995. The OC3
version of the Access Point/ATM product will be available in approximately 60
days.
