摘要： A method for implementing multicast in the Rapid Spanning Tree Protocol loop network includes: the program on the access device is configured to be a fixed port mode, a binding root port mode, or a following upper layer inquirer port mode; the multicast model on the access device traverses the program list when receiving the message of switching root port, updates all the ports corresponding to the programs configured with the binding root port mode to be the changed root ports; or when the multicast model receives the multicast controlling protocol inquire message from a port and determines that the port is different from the recorded global inquirer port, it updates the global inquirer port to be the port receiving the inquire message, and traverses the program table. The multicast model then updates all the ports corresponding to the programs configured with the following upper layer inquirer port mode to be the ports receiving the multicast controlling protocol inquire message.

摘要： 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 make the master block and slave block support the IGMP proxy or the IGMP snooping with the master block and slave block both capable of implementing multicast function independently. The configuration data of the master block and slave block may be both saved in the master block, and a multicast channel and a unicast channel are provided between the master block and slave block for communication. 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.

摘要： The present invention discloses a method for implementing multicast in RSTP (Rapid Spanning Tree Protocol) ring network. In the method, the port mode of a program is configured to a fixed port mode, a root port binding mode or an upper layer querier port following mode; a multicast module on access equipment traverses a program table on receiving a root port switching message, updates the corresponding port of each program whose mode is configured to the root port binding mode as the changed root port; or on receiving an IGMP (Internet Group Management Protocol) QUERY packet from a port which is different from a recorded global querier port, the multicast module updates the global querier port as the port receiving the IGMP QUERY packet, traverses the program table, and updates the corresponding port of each program whose mode is configured to the upper layer querier port following mode as the port receiving the IGMP QUERY packet.
