Extreme Networks Demonstrates Carrier Ethernet Scalability of up to 16 Million Users with Industry's First Test of MAC-in-MAC Technology

Independent Testing by Iometrix Verifies Real-World Implementation of Cost-Effective and Scaleable Carrier Ethernet Networks

SANTA CLARA, Calif., Aug. 1 / -- Extreme Networks, Inc. (NASDAQ:EXTR) today announced the successful implementation of emerging Ethernet standards on Extreme Networks newest service provider offering, the BlackDiamond® 12K, designed to address the scalability of service provider aggregation networks for business and residential subscribers.

Extreme Networks® Multidimensional Ethernet capabilities are comprised of three key dimensions -- MAC-in-MAC scalability, Ethernet Cross Connect technology, and Hierarchical Quality of Service (QoS). These capabilities directly meet the changing needs of carriers to support larger scale networks that enable increased revenue per subscriber on a cost-effective native Ethernet infrastructure.

Iometrix, the lab used to certify Carrier Ethernet products and services for the Metro Ethernet Forum, was commissioned to provide an independent evaluation of Extreme Networks' BlackDiamond 12K modular switch featuring Multidimensional Ethernet. Iometrix performed a comprehensive battery of tests that covered scalability using MAC-in-MAC, the proposed IEEE 802.1ah standard, for provider backbone deployments; Ethernet Cross-Connect technology for directing subscribers to a variety of content networks; and hierarchical per- subscriber, per-application quality of service -- the key components to delivering cost effective and scaleable Carrier Ethernet networks.

"The last hurdle for Ethernet to effectively meet the demands of service provider networks is scalability," said Bob Mandeville, founder and president of Iometrix. "Until Ethernet can effectively scale to support hundreds of thousands of users, it will not be a legitimate solution at the core. This test, the first of its kind, has shown that MAC-in-MAC, and Extreme Networks implementation of Multidimensional Ethernet delivered that scalability."

Test results demonstrated that the BlackDiamond 12K, through Multidimensional Ethernet:

o Extended scalability to millions of distinct service instances with MAC-in-MAC while successfully encapsulating duplicate S-Tags.
o Delivered point-to-point and point-to-multipoint services at wire rate using MAC-in-MAC while guaranteeing subscriber traffic integrity.
o Successfully switched traffic from any selected individual subscriber to specific service instances by mapping C-Tag IDs to S-Tags IDs bi- directionally and at wire rate enabling simple layer 2 connections to content networks.
o Applied bandwidth profiles at both ingress and egress ports and accurately triggered on multiple criteria and at wire rate to prioritize subscriber traffic.
o Dynamically allocated bandwidth among different traffic classes at wire rate.

"Extreme Networks use of emerging IEEE Ethernet standards provides a simple and economical approach for scaling networks beyond the reach of a single metro area," said Peter Lunk, director of service provider marketing for Extreme Networks. "These results show not only the effectiveness of the BlackDiamond 12K, they also demonstrate that Ethernet is ready to extend its dominance in the Enterprise space into carrier networks."

About Multidimensional Ethernet

Multidimensional Ethernet is comprised of three key dimensions:

o Network scaling using Ethernet Virtual Private Networks (VPN) - To scale the network for carriers, Extreme Networks implements MAC-in-MAC technology, a breakthrough capability utilizing standards-based Ethernet to vastly increase the number of Ethernet VPNs per network.
o An Ethernet Cross Connect for simple access to various content networks- This allows service providers to connect subscribers to a growing number of content networks using a Layer 2 approach that is both simple and cost-effective to deploy.
o Guaranteed services with three-tier hierarchical QoS - Extreme Networks' greatly enhanced QoS capabilities can support up to tens of thousands of subscribers per line card with eight QoS service levels for each subscriber. This allows service providers to offer guarantees on the delivery of latency-sensitive services such as IPTV and VoIP.
