The link cost and wavelength resource consumption of the current multi-source multicast routing methods are easily influenced by the variety of the number of destination nodes. To solve this problem,the multi-core multicast routing algorithm based on network coding is proposed. By selecting the multiple core nodes in the network,the algorithm constructs a network coding sub-graph for multicast routing. Then the core nodes selected according to the destination nodes are set as decoding nodes so as to reduce the influence of the number of destination nodes on coding sub-graph. The result shows that the algorithm can reduce the total link cost and wavelength resource consumption effectively in the multi-source network containing lots of destination nodes.
