Summary:Anycast is a new service of IPv6. How to guarantee its quality of service(QoS) has become an important subject. An anycast QoS routing algorithm supporting traffic engineering(ART) in multi-protocol label switching(MPLS) networks is proposed. In order to select a QoS path for client's bandwidth request, information regarding the source-destination pairs is used to reduce the interference between current request and future requests. ART first assigns links weight associated with links residual capacity, servers load and interference on the links from anycast servers to the client. Then it gets the best path by using Dijkstra algorithm. ART uses constraint routing-label distribution protocol(CR-LDP) to reserve bandwidth on label switching path(LSP). Simulations show ART can balance the load of MPLS networks, optimize network resource utilization of anycast, and reduce delay and data loss during server's data transfer.
