HIGH SPEED ROUTER SYSTEM

摘要

PURPOSE: A high speed router system is provided to distribute a portion of an IP(Internet Protocol) packet and a portion of an Internet control message in a line processor, thereby reducing processing load of a non-forwarding packet concentrated on a main processor. CONSTITUTION: Line processor nodes(101) comprise as follows. External physical link connection blocks(1011) are physically connected to external networks. Network processor blocks(1012) perform routing lookup processes after interpreting destination addresses of packets, and forward the routing lookup processes. Microprocessor blocks(1013) communicate with a main processor node(102) with configuration information of the line processor nodes(101). The main processor node(102) consists of a microprocessor block(1021) for communicating with the line processor nodes(101) and processing a routing protocol collecting routing information.
