Infineon Technologies AG is developing devices incorporating OC-192 resilient packet ring (RPR) technology, a technology that is currently being standardized in the IEEE 802.17 committee and that will extend Gigabit Ethernet into metro and wide area networks, paving the way for Gigabit Ethernet metro services. The new devices are expected to augment Infineon's recently announced 40Gbps high-speed framing, mapping, and mux/demux line card solutions.

In an effort to accelerate industry availability of RPR products, Infineon is licensing Cisco's spatial reuse protocol (SRP). SRP is a MAC-layer protocol for ring-based packet internetworking.

"This move reinforces Infineon's commitment to provide complete, standards-based high-speed line card solutions for the optical networking market. RPR networks will enable service providers to combine the reliability of traditional SONET/SDH rings with the richness and scalability of data networks, and to eliminate critical bottlenecks in existing metro networks," said Gerhard Geiger, SVP and general manager of Infineon's Communication Group.
