Problems solved by technology

[0003] In related technologies, for the cross-VLAN multicast function, G.988 expands the dynamic access control list (Dynamic access control listtable) field of the multicast template entity (MulticastOperations Profile, referred to as MOP), by defining the access node interface (Access Node Interface (abbreviated as ANI) side VLAN information to achieve limited cross-VLAN multicast function: but the above-mentioned functions only involve the downlink configuration of the multicast protocol module, not the configuration of downlink multicast data flow

Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] figure 2 It is a flowchart of a method for implementing cross-VLAN multicast according to an embodiment of the present invention. like figure 2 As shown, the method mainly includes the following processing:

[0031] Step S202: The ONU receives the multicast service model from the OLT, wherein the multicast service model includes a newly added extended management entity;

[0032] Step S204: the ONU invokes the extended management entity to modify the configuration information of the downlink multicast data flow.

[0033] In related technologies, the cross-VLAN multicast function only involves the downlink configuration of the multicast protocol module, but does not involve joint modificat...

Abstract

The invention discloses a cross-VLAN multicast implementation method, system and multicast service model. In the above method, the ONU receives the multicast service model from the OLT, wherein the multicast service model includes a new extended management Entity; the ONU calls the extended management entity to modify the configuration information of the downlink multicast data flow. According to the technical solution provided by the present invention, both the downlink configuration of the multicast protocol module and the downlink multicast data flow can be realized, and the effect of promoting the development of the ONU multicast function in the GPON system is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, system and multicast service model for realizing cross-VLAN multicast. Background technique [0002] Gigabit-capable Passive Optical Network (GPON) technology is a point-to-multipoint, full-service gigabit broadband access technology that can provide broadband access, telephone, IPTV, etc. user functions. In the GPON system of some operators, it is often necessary to implement cross-virtual local area network (Virtual Local Area Network, VLAN for short) multicast in live network application scenarios, such as IPTV services. The G.984.4 standard defines a model for multicast services, such as figure 1 shown. Like the unicast data flow, the multicast data flow forms a channel of a specific VLAN by configuring VLAN-related information on the respective physical links. [0003] In related technologies, for the cross-VLAN multicast function, G.988 expands the dynamic ac...
