摘要
随着互联网视频组播业务需求以及结合SDN网络的优越性,设计并仿真了面向SDN网络视频组播系统。本系统采用模块化设计思想,并结合一种跳数、带宽和链路状态相结合的组播路由控制策略,实现了系统的组播系统模块的搭建过程以及视频流媒体的播放过程。最后验证组播路由控制策略和SDN在视频组播系统上的结合,不仅能够提高系统组播的流畅性和稳定性,而且也克服由于网络拥塞、丢包等原因造成的视频通信效果不稳定的问题。
With the demand of Internet video multicast service and the superiority of SDN network, SDN network video multicast system is designed and simulated. This system adopts modular design idea, and combines a multicast routing control strategy that combines the number of jumps, bandwidth, and link state, and realizes the construction process of the multicast system module and the video streaming media playback process. Finally, the combination of multicast routing control strategy and SDN on video multicast system can not only improve the fluency and stability of system multicast, but also overcome the instability of video communication due to network congestion and packet loss.
