Abstract： |
The related method for realizing VPN multicast comprises: VPN network calculates the coverage degree of current multicast member, and decides whether the coverage value less than a given threshold; yes to build a public network multicast distribution tree (P-Tree) with coverage value not less than the threshold. This invention reduces waste of bandwidth. |
