基于SDN的跨IP协议的流量调度优化模型
Traffic scheduling optimization model based on SDN for cross-IP protocols
摘要
Abstract
Aiming at that the conventional traffic engineering is incapable of forwarding IPv4/IPv6 traffic by IPv6/IPv4 link in software defined network(SDN)environment, an improved model for scheduling traffic across different IP protocols in SDN environment is constructed,and a fully poly-nomial time approximation schemes is developed, that is, the traffic scheduling algorithm based on the transition technology.First, the influence of the transition technology on the traffic forwarding performance is transformed into that on the link weight,and the sum of the link weights on each path is calculated.Secondly,the traffic is split,and then the path with the smallest sum of weight is se-lected for each segmented traffic.The experimental results based on MATLAB and Mininet simula-tion show that the traffic scheduling algorithm with transition technology achieves better network per-formance.Compared with the traditional traffic-engineering algorithm and OSPF routing algorithm, the overall throughput of the network is increased by 60%and 145%,the traffic forwarding delay is reduced by 17% and 24%, and the traffic forwarding packet loss rates are reduced by 58% and 76%,respectively by the algorithm.关键词
