Abstract

With the growing speed of computer networks, core routers have to increase performance of longest prefix match (LPM) operation on IP addresses. While existing LPM algorithms are able to achieve high throughput for IPv4 addresses, the IPv6 processing speed is limited. To achieve 100 Gbps throughput, LPM operation has to be processed in dedicated hardware and a forwarding table has to fit into the on-chip memory. Current LPM algorithms need a large memory to store IPv6 forwarding tables or use compression with dynamic data structres, which can not be simply implemented in hardware. Therefore we provide analysis of available forwarding tables of core routers and propose a new representation of prefix sets. The proposed representation has very low memory demands and is suitable for high-speed pipelined processing, which is shown on new highly pipelined hardware architecture with 100 Gbps throughput.
