Embodiment Construction

[0052] The embodiment of the present invention proposes a new multicast configuration protocol—Dynamic Multicast Configuration Protocol (DMCP, Dynamic Multicast Configuration Protocol). Using the DMCP protocol, the embodiment of the present invention realizes the automatic configuration of Layer 2 multicast IGMP Snooping, improving This improves the automation of IGMP Snooping configuration and reduces the configuration workload. The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0053] Please refer to figure 1 , the method for dynamic multicast configuration described in the embodiment of the present invention, comprises the following steps:

[0054] Step 101, when the first node in the two-layer multicast network detects that the IGMPSnooping enabling state of the first VLAN changes, it generates a DMCP report message carrying the IGMP Snooping enabling state change information of the first VLA...

Abstract

The invention provides a dynamic multicast configuration method and node equipment. The method comprises: step A, a second node in a multicast network receives dynamic multicast configuration protocol (DMCP) report message sent by a first node; the DMCP report message is a message which carries with change information of enabling state of IGMP Snooping of a first VLAN and is generated and sent when the first node detects that the enabling state of IGMP Snooping of a first virtual local area network of the first node changes; and step B, the second node configures the enabling state of IGMP Snooping of the first VLAN on the second node according to the change information of IGMP Snooping carried by the DMCP report message. According to the invention, automation of multicast configuration can be realized, the workload of configuration can be reduced and fast convergence of multicast flow rate can be guaranteed after a multicast network link or topology changes.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a dynamic multicast configuration method and node equipment. Background technique [0002] Internet Group Management Protocol Snooping (IGMP Snooping, Internet Group Management Protocol Snooping) is a multicast constraint mechanism running on the Layer 2 (data link layer) device of the Open System Interconnection Reference Model (OSI, Open System Interconnect) system, used for management and Controls multicast groups. The Layer 2 device running IGMP Snooping analyzes the received Internet Group Management Protocol (IGMP, Internet Group Management Protocol) message, and establishes a mapping relationship between the port and the Media Access Control (MAC, Media Access Control) multicast address. And forward the multicast data according to such a mapping relationship. The following briefly introduces the port concepts related to IGMP Snooping in existing protocols: ...
