AMCC, Cisco Team on RPR Development

SAN DIEGO -- Applied Micro Circuits Corp. (AMCC) (Nasdaq:AMCC - news), a leader in high-bandwidth silicon connectivity solutions for the world's optical networks, today announced the development of an OC-48 and OC-192 Resilient Packet Ring (RPR) roadmap with the first product utilizing the Spatial Reuse Protocol (SRP) developed by Cisco Systems and AMCC's framer and Physical Layer technology. RPR technology provides for the efficient and dynamic mapping of bandwidth between various nodes on a ring network. RPR technology also protects traffic without allocating 50 percent of the ring bandwidth as "standby bandwidth" usually found in normal SONET rings. Instead, RPR allocates 100 percent of the bandwidth to working traffic and only reduces allocation on a node-by-node basis in protection circumstances.

"Networks built using RPR technologies will be inherently easier to manage and configure while saving substantial overhead costs for ISPs," said AMCC's John LoMedico, vice president of marketing, Digital Products. "We are very excited to be on the leading edge of an important networking technology and plan to fully support our customers in successfully rolling out the best possible RPR solutions."
