Description

【Technical field】 [0001] The invention relates to the technical field of routers, in particular to an FPGA-based routing acceleration forwarding system, router and forwarding method. 【Background technique】 [0002] Existing traditional routers are generally composed of a host computer plus a corresponding network interface card or a dedicated embedded system. The forwarding is completed by the CPU software, and the forwarding speed is limited by the processing power of the CPU. The routing of software forwarding gradually becomes the transmission bottleneck. [0003] There are also hardware circuits specially designed for packet switching on the market to complete IP packet processing. The rate is much higher than that achieved by software. The switching matrix implemented by hardware can greatly expand the number of routing ports, which is much improved compared to software forwarding. [0004] Traditional routers are generally limited by CPU speed, bus throughput, and slo...
