Embodiment Construction

[0030] The present invention relates to a realization method based on IGMPv3 protocol on PON equipment using two-level source timer to manage multicast members. and report the corresponding information after the multicast group status changes; on the router side, it is necessary to periodically send query messages to the downstream devices to collect the multicast group information of the downstream devices.

[0031] Each interface of the PON device must maintain a set of corresponding multicast group status on the interface, including: group address, group timer, filtering mode, source list and other information; the source list also includes source address and source timer. In this way, two levels of source timers must be maintained at the same time: the first level is on the router side of the PON equipment, which is the port source timer at each PON port, and mainly maintains some request information of the downlink users of the PON port; the other level is on the PON The...

Abstract

The present invention relates to a realization method of multicast member management, in which a global source list and a global source timer corresponding to the uplink port of the host end of the PON device are set in the PON device, and ports corresponding to each PON port of the router end of the PON device are respectively set Source list and port timer; when the multicast group status information under any PON port changes, after updating the port source list and port timer of the PON port, the multicast group status obtained by gathering other PON ports The global state information of the multicast group updates the global source list and the global source timer. The present invention concentrates the implementation methods of the host end and the router end of the IGMPv3 protocol on the PON equipment, and uses two-level source timers to manage the multicast group membership on the network side and the user side respectively, so as to achieve precise control of the multicast flow .

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a realization method for managing multicast members with a source timer on PON equipment. Background technique [0002] IGMPv3 is the third version of the Internet Group Management Protocol, which adds control over multicast sources on the basis of the original protocol. The host and adjacent routers use this protocol to establish and maintain multicast group membership. The host maintains an entry information for each multicast group on the interface. The format is: (multicast address, filtering mode, source list) ; The router maintains a state for each multicast group on the interface, the format is: (group address, group timer, filter mode, source list); the format of the source list is: (source address and source timer). [0003] Among the filtering modes, one is an INCLUDE filtering mode that allows receiving multicast information from a specific multicast source, and t...
