ATLANTA--(BUSINESS WIRE)--June 4, 2002

Product interoperability demonstration at Supercomm 2002

Movaz Networks, a leading provider of optical networking solutions for the Metro Edge, Metro Access & Metro Core, today announced the successful completion of service interworking with Corvis.

Managed Wavelength Services are demonstrated at Supercomm 2002 in Atlanta, GA across the Movaz and Corvis products. With the Movaz RAYexpress OADM as the service on-ramp, connected across a Corvis optical network comprised of the Corvis ON family of products, embedded GMPLS is used to dynamically setup and teardown optical connections. In the configuration to be demonstrated at Supercomm, video traffic is transported across the combined Movaz and Corvis networks via GMPLS instantiated optical connections. This interoperability demonstrates the power of GMPLS control protocols for seamless end-to-end service provisioning across the metro and long haul networks. The real-time management of optical circuits traversing geographically dispersed areas has become a reality with the use of GMPLS which establishes the cornerstone for resilient wide-area transport applications.

"As deployments of Movaz products broaden, multi-vendor interoperability both at the service interface and operational levels has become increasingly important," stated Bijan Khosravi, Founder, CEO and Board chairman of Movaz Networks. "It is a tremendous validation of the values of a unified optical transport infrastructure for diverse service delivery requirements in the metro as well as the operational simplification that could be achieved with the realization of the GMPLS control plane, now generally available in our RAY product portfolio."

"This solution demonstrates best of breed technology to address a substantial market opportunity of $6.2 Billion in 2006 according to Pioneer Research," says Bob Wohlford, Senior Vice President of Marketing, Corvis Corporation. "By leveraging Movaz's leading expertise in GMPLS development in combination with the agility of the Corvis optical core, this combined solution offers the instantaneous wavelength service delivery without incurring extensive support and operations costs for service providers across metro and ultra long haul."

GMPLS is the emerging industry standard suite of control plane protocols for different types of network technologies. GMPLS automates service activation and connection management across IP, Ethernet, SONET/SDH, and optical networks. GMPLS simplifies service management and reduces operational complexity. With GMPLS, services can be delivered more rapidly than is possible using legacy transport network management techniques. Movaz has been very prominent in the specification and standardization of GMPLS and optical internetworking technologies for the communications industry.
