摘　　要：ChinaNet骨干网流量疏导与优化是一项长期的、复杂的系统工程。从ChinaNet骨干网网络结构现状出发,深入分析了中国电信ChinaNet骨干网流量疏导和优化所面临的问题和挑战,阐述了SDN具有流量疏导和优化的天然适应性。结合现网实际情况,自主研发了一套基于SDN的智能路由反射器的流量调优系统,并成功应用于ChinaNet骨干网多个场景的流量疏导与优化实践,取得了预期效果。Traffic optimization of ChinaNet backbone networks is a long-term, complex system engineering. From the status quo of ChinaNet backbone network structure, the problems and challenges laced by traffic optimization in China Telecom＇s ChinaNet backbone networks are analyzed in depth. The natural adaptability of SDN to optimizing network traffic is elaborated. Combined with the actual situation of existing networks, a set of traffic optimization system based on intelligent route reflector has been developed independently and successfully applied to multiple traffic optimization scenarios of ChinaNet backbone networks with the expected results.
