基于SDN的虚拟光网络优化路由算法
Optimizing Routing Algorithm of Virtual Optical Networks based on SDN
摘要
Abstract
Considering the shortage of low bandwidth utilization and congestion of data transmission in traditional optical net-works,we construct a Software Defined Network (SDN)-based virtual optical network that comprises of a packet network and an optical network,and propose a multi-path routing algorithm that optimizes the bandwidth allocation.Under the capacity constraints of the transmission link,we calculate the maximum load of each link and optimize the bandwidth allocation in multi-path routing.With the help of ONOS and Mininet simulation tools,we verify that our algorithm can effectively reduce the de-lay of data transmission and avoid network congestion.关键词
