摘要
PBB技术在电信级城域以太网中有着较好的应用实践,但其存在组播泛洪问题,对所承载业务的服务质量造成了一定影响。因此,提出了一种优化组播泛洪流量的解决方案。通过分离P2P业务,合理规划BVLAN,能将PBB组播泛洪流量控制在一个较小的范围内,从而提高运营商承载网的整体传输效率,并保障用户业务的端到端Qo S。实际组网测试表明,采用优化方式可以有效降低组播泛洪影响的范围,提升网络的整体性能。
The PBB technology has a good application in carrier ethernet, but its multicast-flooding problem would usually make a certain impact on the quality of service. A solution is proposed to optimize the multicast-flooding problem, and the PBB multicast-flooding flow may be controlled in a fairly small range by separating the P2P business and rational planning of BVLAN, thus to improve the overall efficiency of the carrier ethernet and guarantee the end-to-end Qo S. The experiment results indicate that the optimization method could effectively reduce the influence of multicast flooding and improve the overall performance of the network.
