CHICAGO -- Avici Systems (NASDAQ: AVCI) and Limelight Networks today announced that Limelight has chosen Avici Systems SSR™ and TSR® core routers for deployment in its leading content delivery network for Internet distribution of video, music, games and downloads. Limelight selected Avici routers to upgrade its current Internet backbone for their ability to reliably support real-time high-bandwidth media and entertainment delivery to large audiences via the Internet, and cost-effectively scale in-service to accommodate a growing customer base.

Limelight's unique multi-core routing delivery architecture is a generation ahead of other content delivery networks, with complimentary routing deployments to separately handle backbone traffic and edge delivery. Limelight's alliance with Avici gives the service provider industry-leading performance over its "WAN-core" - the fiber-based carrier network infrastructure between its media distribution centers.

"The Avici WAN-core solution delivers a compelling new model that provides Limelight with a key competitive advantage by bringing together the perfect mix of high performance, reliability and scale to our customers at unprecedented price points," said Nathan Raciborski, Chief Network Architect of Limelight Networks. "We believe this represents a turning point in the industry, and we are pleased to be partnering with Avici to provide technology leadership with key advantages we can pass on to our customers. We selected Avici on the merits of the equipment, technology and support - and we are very pleased to be working with them on the buildout of our new content delivery network."

"Avici's vision is to make IP networks simple by removing complexity from as many places as possible. We believe carriers are demanding simpler scalability, reliability and security solutions from their IP suppliers and we are uniquely positioned to deliver on these capabilities," said William Leighton, CEO of Avici Systems. "Limelight is using its network infrastructure with the right combination of technology at the core and at the aggregation/edge to establish itself as a leading provider to enterprises around the world. We are very pleased to be working with Limelight Networks, who also share our view of how IP networks should be built."

Limelight is taking advantage of key Avici technologies including Avici's Composite Links™ and aggregate links which can dynamically aggregate up to 64 physical links into a single logical link, supporting a 10:1 speed differential Limelight can seamlessly expand link capacity to accommodate high-bandwidth applications and improve network utilization without service disruption or costly provisioning. This combined with Avici's NSR™ Non-stop routing for 99.999% availability and Avici's fast convergence solution, RAPID™, provide powerful tools for simplifying the network.

In a separate release:

Avici Systems (NASDAQ: AVCI) today announced its Simple Secure Networks(TM) strategy at SUPERCOMM 2005 through a variety of first-ever technology demonstrations and presentations that focus on allowing service providers to create and deploy networks that are inherently scalable, reliable and secure. Avici will showcase its patent-pending RAPID(TM) technology, its work with the OIF UNI World Interoperability Demo, and presentations by Avici executives to demonstrate the company's approach to simplifying IP networks.

Avici is showcasing a key component of its Simple Secure Networks strategy - its patented Reliable Alternate Paths for Internet Destinations (RAPID(TM)), Avici's fast convergence solution which uses advanced routing algorithms to dramatically speed up recovery times from link and node failures by self-calculating optimum alternate paths without complex manual intervention.

Traditionally, each time a network protocol converges, it causes a service interruption that plays havoc with delay-sensitive/real-time applications such as voice, video and interactive gaming. The magnitude of this problem increases as a network scales. As a result, carriers are unable to offer high-margin, stringent service level agreements (SLAs) without using costly and complex manual protection mechanisms. Avici's RAPID delivers sub 50ms recovery times and is widely supported by the industry, receiving draft acceptance at the IETF.

In addition to its RAPID(TM) demonstration, Avici is one of two core router vendors participating in the widely anticipated OIF UNI Worldwide Interoperability Demo that will showcase the integration of a distributed optical control plane with Ethernet over SONET/SDH. This testbed is the first to explore technical issues of multi-layer signaling and routing in such a network. Benefits to carriers include more efficient networks that automate provisioning and better utilize existing infrastructures. Participating vendors such as Avici are working on-site at carrier lab locations in Asia, Europe and North America, culminating in a live, global real-time network test at SUPERCOMM 2005, booth # 50094.

Avici is also chairing an all-day TecForum sponsored by IEC and SUPERCOMM that includes senior executives from Avici Systems, AT&T, Deutsche Telekom AG, IP-Only, Nortel Networks, Isocore, and Verisign Communications Services. The TecForum workshop entitled, "Service Provider Strategies for Services and Networks Convergence" is designed to educate attendees on strategies for the convergence of networks, services and applications, focusing on VoIP and wireless.

"Avici's Simple Secure Networks strategy is designed to simplify IP networks, focusing on network fundamentals that solve immediate business issues for carriers and lower capital and operational expenses," said William Leighton, CEO of Avici Systems. "Avici is focused on delivering scalable, reliable and high-value routing solutions to service providers worldwide, and our routing solutions are created to make IP networks inherently simple, reliable and secure."
