Embodiment Construction

[0033] Such as figure 1As shown, a method for managing multicast services in an access device of the present invention includes the following steps:

[0034] Step 101, set up one or more independent basic VLANs for multicast services, the basic VLANs only include the multicast service ports on the network side, and do not include user side ports;

[0035] Step 102, create one or more MVLAN information corresponding to basic VLAN by MVLAN (Multicast Virtual Local Area Network multicast virtual local area network) module; Users of the MVLAN, etc.

[0036] Step 103, establish a control list for each user side port through the group access control module, and establish control rules for traversing the control list;

[0037] Step 104, receiving the IGMP protocol message, and passing information such as the receiving port, VLAN ID and group address of the message to the group access control module. This module traverses the corresponding user's control list by the control process...

Abstract

This invention discloses a method to manage multicast business in access device, which comprises: creating one or more independent fundamental virtual LAN; creating module according to the said LAN and one or a plurality of pieces of information opposite to the said LAN; creating control list and control rule for every user port by visiting control module; receiving IGMP protocol message, the control module traverses user's control list according to control rule and returns result; if visiting the control by group, it sends the said message and information to treatment module for corresponding treatment; the set module adds or deletes the user's port according to multicast transposition table item. The invention overcomes the shortcoming in existing technique, such as security hidden trouble and hard to control switch delay and business quality.

Description

technical field [0001] The invention relates to a method for managing multicast services in a network, in particular to the management of multicast services in an edge-access device of a communication network. Background technique [0002] IGMP Snooping (Internet Group Management Protocol Snooping) can "listen" to the IGMP protocol message between the host and the multicast routing device on the Layer 2 network device, and track the user's multicast request. Although IGMP Snooping restricts multicast data forwarding only to specific ports by dynamically configuring device ports, control multicast data is no longer sent to users by flooding VLANs (Virtual Local Area Networks) on network devices. However, as multicast services have increased requirements for access devices in terms of multicast service security, service transmission efficiency, low delay in service switching, QoS (Quality of Service) implementation, easy management, and diverse networking, the existing IGMP T...
