MPLS组播树中协议资源的超限恢复策略的研究

he MPLS multicast tree does not depend on other protocol clusters, and has the characteristics of simple configuration and self-management. However, in the case of the overload scenario in which the routing device uses the resources of the multicast tree, the link convergence speed is slow and some important services cannot be recovered. The delay strategy can have a good suppression effect on frequent oscillations in the network, and the weight model can give optimal decision for the business recovery process. In this paper, the recovery time and recovery quality in the resource overrun are improved. A general delay-based recovery strategy based on weight calculation is proposed to improve the convergence speed of the multicast tree in the resource overload scenario and improve the service recovery quality.
