Nortel Networks Hardware-based Data Compression Coprocessor net module offloads compression and decompression tasks from the main CPU, allowing CPU resources to be used for higher throughput or other packet processing functions. The Hardware-based Data Compression net module supports ISDN, PPP, and Frame Relay links. It is also interoperable with hardware and software compression operating in other Nortel Networks routers. The draft RFC Compression Control Protocol (CCP) is supported along with the Nortel Networks WAN Compression Protocol (WCP). Two compression modes are available: Continuous Packet Compression (CPC) and Packet-by-Packet Compression (PPC). CPC mode maintains a compression history to maximize throughput. PPC optimizes throughput in customer specific applications. The Hardware-based Data Compression Coprocessor net module is available in two models to support different numbers of network paths. The 32 context and 128 context models can be configured to use an 8 KB compression dictionary for each PPP circuit or Frame Relay virtual circuit up to the number of contexts provided in each model. The Hardware-based Data Compression Coprocessor net module occupies one net module position, and one net module is configured per ASN base unit to provide compression services for all WAN interfaces installed in that base unit.| Product Description | Hardware Compression Link Module expansion module | | Device Type | Expansion module | | Form Factor | Plug-in module |
