Multi-vendor, Multi-layer Interoperability Tests Demonstrate Significant Progress in IP-Based Optical Networking Technology

Reston, VA, Oct. 12, 2004 – Lambda OpticalSystems, an advanced optical network solutions provider, announced today that its LAMBDA NODE 2000 Intelligent Optical Switch successfully completed interoperability testing hosted by the University of New Hampshire InterOperability Laboratory (UNH-IOL). The tests confirmed LAMBDA NODE 2000 interoperability with multi-vendor implementations of the Generalized Multi-Protocol Label Switching (GMPLS) standard, an enabler of a broad suite of new communications applications.

UNH-IOL is the networking industry’s premiere independent proving ground for developing technologies, providing leading-edge facilities and support in objective group tests and technology forums devoted to nearly every facet of networking. UNH-IOL designed “Plugfest” – a multi-vendor, multi-protocol test bed – to improve the interoperability of products supporting optical signaling, routing, and management (OSRM). The test items were selected to reflect the most up-to-date requirements of today’s carrier-class network and service scenarios. The results suggest that IP-based optical networking technology is maturing to be suitable for commercial use.

“UNH-IOL does not just test GMPLS protocol conformance. We have developed a rigorous set of tests to emulate the service providers’ real-world networks,” said Henry He, UNH-IOL MPLS services consortium engineer.

“Much of what we have seen in our lab demonstrates that service providers should soon be able to expand their product portfolios with new GMPLS-enabled applications like super-wide bandwidth virtual private networks (VPNs) and bandwidth-on-demand.”

GMPLS provides enhancements to the Multi-Protocol Label Switching (MPLS) standard, supporting optical network switching for time, wavelength, space switching, and packet switching. GMPLS adoption will improve packet switching and photonic networking device performance, providing telecommunications carriers with a scalable and cost-effective means to use optical bandwidth to facilitate the deployment of new services.

“We were delighted to have the opportunity to participate in UNH-IOL’s Plugfest,” said Irfan Ali, president and chief executive officer of Lambda OpticalSystems. “It provided a great vehicle for us to demonstrate our readiness for the market with a carrier-grade quality product.”

The testing included Japanese service provider Nippon Telegraph and Telephone Corporation (NTT), as well as optical equipment and IP routing companies Lambda OpticalSystems, Agilent Technologies, Juniper Networks, Navtel Communications, Sycamore Networks, and Tellabs Inc. Lambda OpticalSystems worked with NTT on Layer-1 VPN.

About the University of New Hampshire InterOperability Laboratory

Established in 1988, the University of New Hampshire InterOperability Laboratory (UNH-IOL) is a non-profit organization that offers comprehensive interoperability and conformance-based testing through 19 technology-based groups, called consortiums. Test solutions created at the UNH-IOL offer a set of methods to increase interoperability through protocol operations, signaling, point-to-point and multi-system scenarios.
