Abstract

The invention discloses a multicast service realizing method and a multicast service realizing device. The method comprises the following steps of: creating one or more multicast entities, wherein the multicast entities are not associated with any bridge of a plurality of bridge models; when a bridge in the plurality of bridge models has a multicast service requirement, creating a multicast data channel according to virtual local area network (VLAN) information of the multicast entities and the VLAN information of the bridge user; and transmitting multicast service data by using the multicast data channel. Through the technical scheme provided by the invention, the problem that multicast services cannot be realized in a multi-bridge mode in the prior art is solved, so when a plurality of bridges exist, each bridge can realize the effect of multicast function as expected.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and device for realizing a multicast service. Background technique [0002] Gigabit Passive Optical Network (GPON for short) is a point-to-multipoint, multi-point For services, use GPON Encapsulation Method (GPON Encapsulation Method, referred to as GEM) frames to carry various services, and can provide quality of service (Quality of Service, referred to as QoS) guaranteed gigabit broadband full-service access technology. [0003] In the Gigabit passive optical network system, the GPON standard G.984.4 defines several service models for Layer 2 functions. The bridge model is a typical model. A simple bridge model is defined as figure 1 shown. Specifically, the media access control bridge service profile (Media Access Control Bridge Service Profile, referred to as MAC Bridge Service Profile) management entity through the access side network interface (Access network...
