Embodiment 1

[0046] Embodiment one further includes:

[0047] If the VPN instance cancels the multicast function, the PE sends a cancel group CG message to the DDR, indicating that the share-group of the VPN instance is cancelled; the DDR receives the CG message from the PE, checks and resolves it, releases the locally allocated group resources, and returns an ACK Message to PE.

Embodiment 2

[0048] Example two such as image 3 shown, including:

[0049] 301. The PE sends a request to switch group RSG message to the DDR.

[0050] When the PE detects that the data rate of a certain multicast group is higher than the threshold and needs to switch the MT, it sends an RSG message to the DDR. The information carried in the RSG message includes: the loopback address of the PE, the MT address, the RD of the VPN instance, (S, G ), private network group address. Thresholds can be set according to current network conditions.

[0051] 302. The DDR sends a message of assigning a switching group DSG to the PE.

[0052] After receiving the RSG message, the DDR determines the VPN to which the private network multicast group belongs according to (S, G) and the private network group address, checks the resource allocation of the local Switch-Group, allocates the Switch-Group, and sends a DSG message to the PE. In the DSG message The carried information includes: MT address, RD of...

Abstract

The embodiment of the invention discloses a method, a router and a system for resource distribution in the virtual private network. The method of the invention example comprises: appointing a distribution router to check the local resource distribution and distribute resource; appointing a distribution router to send the resource distribution information to the provider edge. By adopting the method of the embodiment of the invention, the resource data can be in unified and centralized configuration, which is helpful for local adjustment and maintenance. Furthermore, the invention can avoid conflicts of multicast group of public network.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, router and system for resource allocation on a VPN (Virtual Private Network, virtual private network). Background technique [0002] VPN is a technology that relies on Internet Service Provider (ISP, Internet Service Provider) and Network Service Provider (NSP, Network Service Provider) to establish a dedicated data communication network in the public network. In VPN, the PE (Provider Edge, provider edge) routing device in the public network establishes a connection with the CE (Client Edge, user edge) routing device in the private network, and CEs belonging to the same private network can communicate through the public network , to realize the establishment of a dedicated data communication network in the public network. [0003] With the wide application of VPN technology, users have an increasingly urgent need to operate multicast services in VPN. The MD (Mult...
