SDN 中基于负载均衡的最优路径分配算法研究
Optimal path allocation algorithm based on load balancing for SDN
摘要
Abstract
To solve the problem that path allocation algorithm has poor globality and lack of real-time in the tightly couples of traditional network control and forwarding,the paper used centralized control of software defined networking (SDN)to propose the MC-LB algorithm.The method calculated link importance by transition probability of Markov chain,and optimized the business flow request quantity and the load balance rate of network simultaneously to get optimal path in multi-requests.Large experiment results comparing analysis prove that the algorithm is superior to the traditional SPF (shortest path first)algorithm which can increase the 30% network load balance rate and 20% business flow request acceptance rate in some cases.The pro-posed algorithm achieves the effect of load balancing and improves the performance of network.关键词
