基于FPGA的ICN名字解析缓存加速系统
Design of ICN name resolution acceleration system based on FPGA
摘要
Abstract
Name resolution service is the key to retrieving information content in ICN(information-centric networking).Therefore,an FPGA-based ICN name resolution acceleration system is designed and proposed to enhance the efficiency of name resolution services and reduce the load on name resolution systems.This system offloads the name resolution function to FPGA on the data plane of network nodes,achieves the mapping storage of identifier-to-network address and processes forwarding data packets that require to find the network address.Additionally,the system supports dynamic configuration of mapping relationships on the control plane,and ensures the update of mapping storage.Experimental test results show that the proposed system achieves a forwarding rate of 4.6 Mpps for small packets when the test traffic is 10 Gb/s,with a request latency below 1.5 μs.In comparison with the traditional software-based key-value storage systems,the processing speed of the proposed system is increased by 27 times,and it is 4 times faster than the processing speed of software optimized with DPDK kernel bypass.关键词
