Abstract
Embodiments of the present invention provide a method and a system for implementing multicast using a slave block in DSL access technique. Several slave blocks are cascaded with a master block accessed to the DSL. The master block and slave block are respectively connected with DSL users via RTUs, and access an uplink via a network interface of the master block. The slave block is configured to support the IGMP proxy or the IGMP snooping so as to implement multicast function independently. This invention overcomes the shortcomings including the heavy burden on the master block, low efficiency and serious waste in bandwidth resulting from the fact that the operation of the slave block multicast member is implemented in the master block, thus increasing the efficiency of multicast and saving bandwidth of the master block.
