The Frea™ is a single-chip OC-192c/48c device that supports Resilient Packet Ring (RPR) protocol on both SONET/SDH and 10GbE PHYs. RPR, a layer two Media Access Control (MAC) technology, significantly RFC 2892 increases the bandwidth efficiency of service provider networks by utilizing twice the capacity of traditional SONET/SDH rings. RPR delivers dynamic bandwidth management while preserving the same kind of protection and resiliency found in SONET/SDH RFC 2892 networks. The Frea chip integrates RPR MAC, PoS (Packet-Over- SONET) framer and XAUI SerDes (Serializer/Deserializer) necessary to deploy RPR rings in Metropolitan Area Networks (MANs) and Wide Area Networks (WANs). It also eliminates external memory by including 1 MB of memory on-chip for RPR operation. The Frea chip supports both IEEE 802.17 RPR standard Draft 2.1, and RFC 2892 SRP protocol. It also operates in a PoS framer-only mode, which allows carriers unparalleled flexibility to build legacy PoS networks that can later be configured to RPR through a simple software upgrade.
