Problems solved by technology

This will inevitably increase the burden on the main control card in the realization of multi-multicast VLAN system
Moreover, due to the huge number of users of OLT equipment terminals on the access network, after the multicast VLAN video service is enabled, the amount of multicast protocol packets is also very large, which may also cause equipment performance problems

Abstract

The utility model provides rack-type OLT equipment and a method for achieving a multicast VLAN therefor. The OLT equipment comprises a main control card and a plurality of line card. The main control card comprises a main control multicast protocol module, and each line card comprises a PON chip, a switching chip, and a line-card multicast protocol module. The method is that the line-card multicast protocol modules are enabled to participate in the processing of a multicast protocol through separating a part of functions from the main control multicast protocol module; the line-card multicast protocol modules extract a group address and the multicast VLAN according to a first multicast protocol message from a user side, so as to form a second multicast protocol message which is sent to a main control card; the main control multicast protocol module extracts the a group address and a multicast VLAN according to a second multicast protocol message, so as to form a third multicast protocol message which is sent to a network side. The method can greatly reduce workload of the main control card of the rack-type OLT equipment, and can greatly prevent an illegal multicast to join a message which is sent to the main control card.

Description

technical field [0001] The invention relates to a device and a method for realizing multicast VLAN, in particular to a rack-type OLT device for realizing multi-multicast VLAN, and a method for realizing multi-multi-cast VLAN by using the rack-type OLT device. Background technique [0002] In today's data communication networks, the demand for video services is ubiquitous. Due to the large data traffic of video services, multicast is a point-to-multipoint, that is, single-point transmission and multi-point reception or multi-point transmission and multi-point reception. The high-efficiency data dissemination technology is widely used in video services because it can effectively reduce network load and save network bandwidth. Operators use central office equipment to enable multicast services. For different access providers, operators consider using different VLANs (Virtual Local Area Networks) to distinguish them. [0003] At present, general access network equipment as a wh...
