随着OpenFlow技术的发展,各大网络厂商相继研发OpenFlow交换机.由于OpenFlow协议版本快速更新,网络厂商不敢盲目定制硬件.立足现有商业交换机的硬件平台,不改变交换机硬件,采用软件方式统一有效的管理交换机现有的硬件存储表,实现OpenFlow超长的流表项匹配和复杂的行为,研发出一款支持多流表查找的交换机,并完成了多流表交换机模型建模,完成数据包多流表查找的时间延迟分析,得到多流表查找的延迟函数,并测量了多流表处理的性能,为后续OpenFlow多流表实现具有一定的指导意义.
With the development of OpenFlow technology, major network vendors have successively developed OpenFlow switches.As the OpenFlow protocol version is rapidly updated, network vendors can not blindly customize the hardware.Based on the hardware platform of the existing commercial switchboards, the switch hardware is not changed and the software is used uniformly Manages the existing hardware storage table of the switch, realizes OpenFlow long flow entry matching and complex behavior, develops a switch that supports multi-flow table lookup, completes modeling of a multi-flow table switch model, completes a data packet Multi-flow table to find the time delay analysis, multi-flow table to find the delay function, and measured the performance of multi-flow table processing, follow-up OpenFlow multi-flow table to achieve a certain degree of guiding significance.
