Research on Programmable Data Plane Load Balancing based on Multipath Selection
Liqiong He, Ling OU · 2017
The switching equipment on traditional networks have limited capabilities and the exchange of the switching equipment is often associated with long time frame and high development cost.SDN deployment controller under the flow table rules also exists to handle message delay.In this paper, we propose a scheme based on multipath selection of programmable data plane load balancing.We use the P4 language to directly write the data plane flow control multipath program, and then use the improved equivalent multipath routing path matching and port selection to achieve the path efficient allocation and traffic load balancing scheduling.Finally, the NS2 simulation results show that, compared with the traditional equivalent multipath, the improved multipath selection scheme can lower the end-to-end delay, reduce the packet loss rate and improve the throughput.
