Press Release

Pittsburgh, PA - September 3, 2003 — Laurel Networks, Inc., the first provider of high-performance service edge routers, today announced that DACOM, one of the leading service providers in Korea, has selected the ST200™ Service Edge Router to deliver scalable, QoS-enabled Layer 2 and IP VPN services from the edge of its network.

The ST200 allows DACOM to extend its leading ATM service across its metropolitan Ethernet access network without sacrificing the high QoS of its existing offering. DACOM is also introducing next-generation Ethernet services delivered with sophisticated QoS characteristics via the ST200. At the same time, the flexible ST200 will enable DACOM to offer new, scalable IP VPN services without the use of additional devices.

Only the ST200 supports Layer 2 and IP-based services on a single device with unmatched scale and performance as customers and services are turned up. This provides a key advantage to DACOM since fewer devices are required and more services are supported per customer, with the additional flexibility to software-configure new services and speeds as customer needs change.

"For edge routers, Laurel is the clear leader, even for traditional core functions like OSPF/BGP routing throughput," said Mr. Byung Chang Choi, network switching division executive director at DACOM. "And, when it came to putting a range of interfaces in a single platform, Laurel had no peer."

"DACOM is one of the world's top service providers and a leader in the use of innovative technology to support their customers' evolving requirements," said Steve Vogelsang, co-founder and vice president of marketing, Laurel Networks. "The ST200 was designed specifically to meet the demands of the multi-service edge, and we are extremely pleased that DACOM is deploying the ST200 to offer a range of Layer 2 and IP-based offerings from our platform."

"The IP VPN service takes the flexibility of the Internet and adds to it sophisticated Quality of Service," said Mr. Jung Rae Jun, senior manager of DACOM. "No other technology comes close to MPLS in enabling the VPN capability that makes these services private, flexible and secure. On top of that, IP VPNs are a means to extend the reach and scalability of legacy Frame Relay and ATM networks, not a replacement for these services."
