摘要
针对WLAN A(C无线局域网接入控制器)系统中日益增长的无线网络带宽对数据转发性能的要求,研究了Octeon多核网络处理器,提出了对网络流量按照数据面和控制面进行核间分离的处理架构。在控制面进行三层转发表的生成和对数据面的同步,在数据面通过LC-Trie(级压缩单词查找树)算法的回溯优化实现快速IP地址查找方法,有效地提高了三层转发的性能。
For increasing wireless network bandwidth requirement for data transfer performance in WLAN AC system,Octeon multi-core network processor is studied,a nuclear separation processing architecture based on data plane and control plane is proposed for network traffic.The control planegeneratesthe forwarding table and synchronizes to the data plane.The data plane realizes a fast IP address lookup optimization method based on LC-Trie.It improves the performance of the Layer 3 forwardingeffectively.
