Research of Egress Traffic Optimization in the Dual-stack Multi-outlet Network

To solve the bottleneck of ISP and backup link,campus network uses multi-outlet link,and its limited export bandwidth is occupied intensely by P2P applications.This paper first introduces the key technologies for flow control and link load balancing,etc.,then applies these two technologies to propose an idea of a multi-link campus network outlet flow optimization,combines with the Beijing Jiaotong university campus network to research the implementation of the method.Finally,the optimization techniques of the Ipv6 outlet flow in campus network are discussed.
