摘要
尽管目前在光网络上可以用很多种方法来分配资源,但是它们并没有考虑到影响服务质量的第三层延迟。提出了一个考虑了第三层延迟的建立显示路由ER的算法,通过最优化目标函数来确定是否可建立显示路由,仿真结果证明了其有效性。
Although there have been many approaches to allocate resources in optical networks, these dont consider the delays at layer 3, which impacts QoS. This paper presents an algorithm to set up explicit route considering the traffic flows with delay at layer 3 by optimizing an objective function to estimate the feasibility of setting up an ER.
