Abstract
The invention provides a fast convergence method and device of Ethernet ring network multicast Proxy mode business, and relates to the field of Ethernet ring networks. The method comprises the following steps: when a departure message is received, deleting a packet receiving port from a multicast group member; and checking the multicast group member, if the multicast group member only has one ring network port left, sending the departure message to the ring network port, and deleting the ring network port from the multicast group member. According to the fast convergence method and device provided by the invention, the ''ping-pong effect'' in the ring network Proxy multicast is effectively solved by processing upper nodes, intermediate nodes and edge nodes in an IGMP Proxy mechanism, and the multicast flow can be converged within a relatively short time, thereby avoiding long-term occupation of network bandwidth.
Description
Technical field
The present invention relates to ethernet ring network field, be specifically related to a kind of ethernet ring network multicast agent Proxy pattern
The method and apparatus of business fast convergent.
Background technology
Ethernet ring network is the Ethernet a kind of typical case's networking application on Metropolitan Area Network (MAN), solves traditional data net
The problems such as protective capability is weak, failure recovery time is poor, using the teaching of the invention it is possible to provide the quick protection feature of 50ms, have
The service quality that improve network of effect and reliability.
Ethernet ring network has the advantage supporting multicast application, and traditional data net is each multicast branch node
It is required to carry out the duplication of multicast data flow on individual second line of a couplet port, and ethernet ring network only need to replicate on whole looped network
Multicast data flow, thus substantially increase the effectiveness that multicast traffic stream replicates.
As it is shown in figure 1, any node equipment in ethernet ring network (except connecting the root node of multicast source) is all
Being reciprocity, between node, the port of interconnection is source port, is also receiving port.If it is considered that many multicasts
The scene in source, then on looped network, all interconnection port are source port, are also receiving ports.
For loop network multicast business, generally use IGMP (Internet Group Management
Protocol, the Internet Group Management Protocol) Proxy pattern, can avoid a large amount of protocol massages that network is produced
Impact or generation loopback storm.But there is " ping-pong ", i.e. phase in looped network IGMP Proxy pattern
Can be added to mutually sending out query message between adjacent device node.Even if on a node all users all from
Open, owing to looped network port is also in multicast group, the mechanism left according to Proxy pattern end user,
Now will not send to source port and leave message, cause multicast cannot stop on looped network, take net all the time
Network bandwidth, business cannot restrain.
Summary of the invention
The present invention provides the method and apparatus of a kind of ethernet ring network multicast Proxy mode business Fast Convergent,
Enable to flux of multicast convergence within a short period of time.

Detailed description of the invention
For making the goal of the invention of the present invention, technical scheme and beneficial effect of greater clarity, below in conjunction with
Embodiments of the invention are illustrated by accompanying drawing, it should be noted that in the case of not conflicting, this Shen
Embodiment in please and the feature in embodiment can mutual combination in any.
As in figure 2 it is shown, can will cut out through STP (Spanning Tree Protocol, Spanning-Tree Protocol)
Ethernet ring network after cutting regards a chain structure as, there is the node device of three types: first line of a couplet node is (even
Connect multicast source), (only one end is in and turns for intermediate node (two ends are in forwarding state) and fringe node
Hair-like state).
Wherein, looped network port: the interconnection port between ethernet ring network interior joint, it is source port, is again
Receiving port；
Packet receiving port: receive the port of protocol massages；
Source port: connect the first line of a couplet port of multicast source；
Receiving port: connecting the port of user, multicast traffic stream and agreement query message forward from this port
Go out.
As shown in Figures 2 and 3, a kind of method of ethernet ring network multicast Proxy mode business Fast Convergent,
It is applied to fringe node or intermediate node, including:
When fringe node or intermediate node receive and leave message, packet receiving port is deleted from multicast member

Embodiment one:
As it is shown in figure 1, ethernet ring network is made up of 4 nodes, its interior joint 3 connects multicast source, port
2,3,4,5,7,8,9,10 is looped network port.Its middle port 6 is configured to source port, and 1 is configured to
Packet receiving port, 2,3,4,5,7,8,9,10 is source port, is also receiving port.Port 9
With 10 stp state be block.
On node 1, user sends and joins message, and adds multicast group 224.1.1.1, and adding port 1 is multicast
The member port of group 224.1.1.1, sends from source port 2 simultaneously and joins message；Node 2 receives addition report
Literary composition, adds multicast member by port 3, sends from source port 3,4 simultaneously and joins message, goes down successively
The looped network port of all interconnections is added to the member port of multicast group 224.1.1.1 successively, and node 3 is to port
6 transmissions join message to multicast source, make multicast traffic stream enter node 3 from port 6 and down forward.
Now, port 1,2,3,4,5,7,8 is the member port of multicast group 224.1.1.1.Multicast
224.1.1.1 data stream turns along 6 → 7 → 8 and 6 → 5 → 4 → 3 → 2 → 1 to all nodes and user respectively
Send out.
Fringe node 4 does not has the multicast group request user of correspondence, and therefore this node of data flow forwards and takies
Bandwidth.Sending out query message mutually by port 7,8 between node 3 and node 4, node 4 receives inquiry report
Literary composition checks that only looped network port 9, in multicast group, is not responding to this query message, the port 7 in node 3
Being deleted from multicast group 224.1.1.1 member by aging, data stream will no longer forward toward node 4.
On node 1, user sends and leaves message, leaves multicast group 224.1.1.1, by port 1 from multicast group
Member deletes, now the member of inspection multicast group 224.1.1.1, only one of which looped network port 2, therefore
Send from port 2 and leave message, and port 2 is deleted from multicast member.Node 2 receives and leaves
Message, deletes port 3 from multicast member, checks that multicast member only has looped network 4, therefore from
Port 4 sends and leaves message, and is deleted from multicast member by port 4.Go down successively, in looped network
All looped network ports are the most no longer the members of multicast group 224.1.1.1, and node 3 to port 6 send from
Opening message to multicast source, multicast source is by the data stream of the most down forwarding multicasting group 224.1.1.1.
Although disclosed embodiment is as above, but its content is only to facilitate understand the present invention
Technical scheme and the embodiment that uses, be not intended to limit the present invention.Technology belonging to any present invention
Skilled person, on the premise of without departing from disclosed core technology scheme, permissible
The form implemented and details make any amendment and change, but the protection domain that the present invention is limited, still
Must limit in the range of standard with appending claims.
