基于NFV的QoS多源多播蚁群优化算法

QoS Multi-source Multicast Ant Colony Optimization Algorithm Based on NFV

针对构建含QoS的多源多播网络以及其与网络功能虚拟化(NFV)的结合,提出一种基于蚁群优化的QoS多源多播路由算法(AQoSMMTC),并对多源多播网络中虚拟网络功能节点(VNF)部署问题进行了改进,进而提出了基于NFV的QoS多源多播蚁群优化算法(VQoSMMTC)。并对其进行实现和测试,试验结果表明该算法能够成功的构建满足QoS需求的多源多播树,优于同类算法。并能有效解决支持NFV的多源多播树构建问题。

Aiming at the construction of multi-source multicast network with QoS and its combination with network function Virtu⁃alization(NFV),this paper proposes a QoS multi-source multicast routing algorithm based on Ant Colony Optimization(AQoSMMTC),improves the deployment of virtual network function node(VNF)in multi-source multicast network,and then proposes a QoS multi source multicast ant colony optimization algorithm based on NFV(VQoSMMTC).The experimental results show that the algorithm can successfully build a multi-source multicast tree to meet the QoS requirements,which is better than other similar algorithms.And it can effectively solve the problem of multi-source multicast tree construction supporting NFV.
