Abstract
Aiming at the problems that it is difficult to build an optimal multicast tree and its convergence is slowly in layer 2 Ethernet, a new optimal multicast tree construction method is proposed in this paper. This method put IS-IS protocol to compute the shortest path tree for layer 2 Ethernet. By means of the Code-Length-Value(CLV) of expanded link-state bag to improve its notice mechanism, an optimal multicast tree can be easily construct. The optimal multicast tree can be reconstructed fast when network topology changed. Test results show that the method can make the time of multicast tree convergence be reduced from 10 s~20 s to 50 ms and ensure that the tree is an optimal multicast tree.关键词
