METHOD AND APPARATUS FOR TRANSMITTING DATA BASED ON POINT-TO-MULTIPOINT USING SUB-GOURP ON MULTI-PROTOCOL LABEL SWITCHING-TRANSPORT PROFILE NETWORK

摘要

A kind of method and apparatus are disclosed, are used to send profile (MPLS-TP) network of multiprotocol label switching business of point-to-multipoint (P2MP) data based on subgroup. According to the present invention, this method is used to send the P2MP grouping transmission of data grouping, includes the following steps: that branch node receives the information of grouping from source node; Branch node receives data grouping from source node; The branch node determines subgroup, and the grouping of data instruction is shown as the information of subgroup; Work as subgroup, the grouping of data instruction is shown as the information of subgroup, determines that the branch node receives leaf node and to send the information based on subgroup and subgroup according to grouping; Data packet is sent to leaf node is received with above-mentioned branch node, and the path other than residual paths is blocked to be sent to reception leaf node. ;The 2016 of copyright KIPO submissions
