摘要

如何实现网络负载均衡，同时满足带宽和时延对服务质量(QoS)的要求是一个挑战。本文设计并实现了一个基于软件定义网络(SDN)和sFlow的组播路由系统。该系统是在RYU控制器的基础上开发的。我们的主要贡献有:(1)我们的系统兼容基于Internet Group Management Protocol (IGMP) v2和多播地址的传统多播应用;(2)根据sFlow精确计算的当前可用网络带宽，为组播应用选择最优路径;(3)有效减少不必要的网络流量并实现负载均衡，从而降低组播中的丢包率和时延。

Design and implementation of multicast routing system over SDN and sFlow

It is challenging to achieve network load balancing, simultaneously meeting the quality of service (QoS) demands of bandwidth and delays. In this paper we have designed and implemented a multicast routing system over Software Defined Networking (SDN) and sFlow. The system has been developed on the top of RYU controller. Our main contributions are: (1) compatibility of our system with traditional multicast applications which are based on the Internet Group Management Protocol (IGMP) v2 and multicast address; (2) choosing the optimum paths for multicast applications on the basis of currently available network bandwidth which is calculated accurately by sFlow; (3) reduction in unnecessary network traffic effectively and load balancing, thereby reducing the packet loss rate and delay in the multicast.
