Spatial Reuse Protocol (SRP) Model developed with Cisco Systems to enable Service Providers to plan and build IP+Optical Ring Network Architectures

WASHINGTON, DC., December 4, 2000 - OPNET Technologies, Inc. (Nasdaq: OPNT), the leading provider of predictive network management software, today announced the industry's first SRP model for network design and planning.

The model, developed in conjunction with Cisco Systems Inc., enables IP service providers and large enterprises to create virtual representations of proposed IP+Optical ring networks as they evaluate the capacity and quality of service (QoS) characteristics of alternative design proposals. The model represents Cisco Systems Inc.'s Dynamic Packet Transport (DPT) implementation of the SRP protocol.

OPNET developed the SRP model for use with its OPNET Modeler platform. OPNET is a Test & Modeling Partner for service providers building, implementing and managing DPT/SRP networks. Principal applications for DPT/SRP include ISP intra-POP connectivity, regional metropolitan IP internetworking, and broadband metropolitan Internet access.

"The OPNET SRP model is an important predictive management asset for carriers and enterprises that are committed to IP+Optical ring solutions. The OPNET SRP model also helps educate network professionals who want to gain a thorough understanding of SRP's capabilities and nuances," said Melanie Houghton, Vice President of Strategic Business Development at OPNET. "It's clear that IP+Optical technologies will play a major role in next-generation networks and we're eager to continue supporting innovations such as Cisco's implementation of SRP."

The OPNET SRP model supports Cisco's submission of its implementation to the IEEE 802 Resilient Packet Ring Study Group for consideration as a standard.

"By combining IP's intelligence and scalability with the capacity of fiber optics, customers can dramatically reduce network administration and management costs," said Graeme Fraser, Cisco vice president and general manager. "OPNET's implementation of the spatial reuse protocol model will enable service provider customers to dynamically model networks and build resilient packet rings. This will help accelerate the delivery of IP+Optical networks to data network customers, bringing them more information more efficiently and more cost-effectively than ever."
