Method, apparatus and system for forwarding multicast program

摘要

The present invention provide a method for forwarding a multicast program includes: receiving a multicast join request message requesting an on-demand program from a user; obtaining forwarding decision information according to the multicast join request message; determining a decision result corresponding to the forwarding decision information according to the forwarding decision information and forwarding relation data, where the decision result is forwarding according to PON replication or forwarding according to user replication, the forwarding relation data includes data elements indicating correspondence between various types of forwarding decision information and various types of forwarding modes, and the various types of forwarding modes include the forwarding according to PON replication and the forwarding according to user replication; and forwarding the on-demand program to the user according to the decision result.

1. A method for forwarding a multicast program, comprising:
receiving, by an Optical Line Terminal (OLT), a multicast join request message from a user for requesting an on-demand program; obtaining, by the OLT, forwarding decision information according to the multicast join request message; acquire, by the OLT, a decision result by searching data elements with the obtained forwarding decision information; wherein the data elements indicate a correspondence between various types of forwarding decision information and various types of forwarding modes; wherein the various types of forwarding modes comprise a forwarding according to Passive Optical Network (PON) replication and a forwarding according to user replication; wherein the decision result is the forwarding according to PON replication or the forwarding according to user replication; and forwarding, by the OLT, the on-demand program to the user according to the decision result.
