In, the first main link and the second main link are relative, and the processing procedure of the first main link and the second main link
Processing procedure it is identical.Under the application scenarios shown in Fig. 3, for subring 1, the first main link is node 1, the second main ring section
Point is node 2, or, the first main link is node 2, and the second main link is node 1.For subring 2, the first main link
For node 2, the second main link is node 3, or, the first main link is node 3, and the second main link is node 2.For
Subring 3 or subring 4, the first main link is node 3, and the second main link is node 4, or, the first main link is section
Point 4, the second main link is node 3.
Describe for convenience, illustrate by taking the process of the first main link as an example in the embodiment of the present invention.
As shown in figure 4, the data message transmission method that should be based on subring link is comprised the following steps：
Step 401, the first main link selects the first main link corresponding with the common link between the second main link
Backup link.Wherein, common link is specially between the first main link and the second main link the link being located on main ring,
And backup link is specially between the first main link and the second main link and is located in subring and through the chain of subring host node
Road.
Under the application scenarios shown in Fig. 3, the common link between node 1 and node 2 is the link between port 2 and port 3,
Backup link between node 1 and node 2 is the link between node 1- node 5- nodes 2.Common link between node 2 and node 3
For the link between port 4 and port 5, the backup link between node 2 and node 3 is between node 2- node 6- node 7- nodes 3
Link.Common link between node 3 and node 4 is the link between port 6 and port 7, the backup link between node 3 and node 4
For the link between the link between node 3- node 8- nodes 4, or node 3- node 9- nodes 4.
In order to the backup link for ensureing selection can carry out data-message transmission, then backup link needs available in backup
State, the i.e. subring of backup link place are complete, now can carry out data-message transmission based on backup link.Wherein,
When backup link be located subring it is complete when, backup link in backup upstate, when backup link be located subring it is not complete
When whole, backup link is in down state.
Based on this, in the embodiment of the present invention, the first main link is selected between the first main link and the second main link
Common link corresponding to backup link process, be specifically including but not limited to following manner：First main link is being received
From three message of subring host node when, determine that link in subring is complete, can now select the first main link and the
Between two main links in the subring and through subring host node link be common link corresponding to backup link；
First main link determines that the link in subring is imperfect when receiving from four message of subring host node, now can be with
Select between the first main link and the second main link in the subring and through the link of subring host node be not public
Backup link corresponding to common link.
Wherein, the 3rd message is specifically as follows CompleteFDB（Complete forwarding database）Message, subring host node is being sent out
When sending CompleteFDB messages, show that the link in subring is complete, therefore the first main link is being received from subring host node
CompleteFDB messages when, determine that the link in subring is complete.4th message is specifically as follows CommonFDB（Common forwarding
Database）Message, subring host node shows that the link in subring is imperfect when CommonFDB messages are sent, therefore the first master
Link point determines that the link in subring is imperfect when receiving from the CommonFDB messages of subring host node.
Under the application scenarios shown in Fig. 3, when node 1 is received from the CompleteFDB messages of node 5, it is determined that sub
Link on ring 1 is complete, therefore node 1 can select the link between node 1- node 5- nodes 2 as between port 2 and port 3
Link（Common link between node 1 and node 2）Backup link；Report from the CommonFDB of node 5 when node 1 is received
Wen Shi, determines that the link in subring 1 is not completed, therefore node 1 will not select the link between node 1- node 5- nodes 2 as end
Link between mouth 2 and port 3（Common link between node 1 and node 2）Backup link.
In order to avoid the backup link that Edge node and assistant edge node is selected it is inconsistent, in the embodiment of the present invention, the
One main link selects the process of the backup link corresponding to the common link between the first main link and the second main link,
It is specifically including but not limited to following manner：When the first main link is fringe node, if the link in subring is complete, the
One main link select between the first main link and the second main link in the subring and through subring host node
Link is the backup link corresponding to common link, and is taken in the second main link transmission the 5th message, and the 5th message
With the subring ID of subring；Afterwards, the corresponding links of subring ID are selected for corresponding to common link by the second main link
Backup link.Additionally, when the first main link is to aid in fringe node, the first main link is received from the second main link
The 6th message, and carry in the 6th message the second main link selection backup link corresponding to subring subring ID；
After the 6th message is received, the first main link selects the subring ID correspondences carried in the 6th message to first main link
Link be common link corresponding to backup link.
Wherein, the 5th message and the 6th message are Edge-Hello（Edge health detection）Message, the embodiment of the present invention
In, by introducing new field in Edge-Hello messages, to carry subring ID by the new field, edge is ensured then
The backup link that node is selected with assistant edge node is consistent.
Under the application scenarios shown in Fig. 3, when the link in subring 3 it is complete, and the link in subring 4 it is complete when, then：Section
Point 3 can select the link between node 3- node 8- nodes 4 as the link between port 6 and port 7（Node 3 and node 4
Between common link）Backup link, afterwards, node 3 is notified the subring ID of subring 3 to section by Edge-Hello messages
Point 4, the link between node 3- node 8- nodes 4 is selected as the link between port 6 and port 7 by node 4（Node 3 with
Common link between node 4）Backup link.Or, node 3 can select the link between node 3- node 9- nodes 4
As the link between port 6 and port 7（Common link between node 3 and node 4）Backup link, afterwards, node 3 lead to
Cross Edge-Hello messages the subring ID of subring 4 to be notified to node 4, selected between node 3- node 9- nodes 4 by node 4
Link is used as the link between port 6 and port 7（Common link between node 3 and node 4）Backup link.
In above-mentioned selection course, the priority of subring can also be configured, when multiple subrings are complete, to determine each son
Selected priority between ring.Based on this, if the priority of configuration subring 3 works as subring higher than the priority of subring 4
Link on 3 is complete, and the link in subring 4 it is complete when, the node 4 of node 3/ needs to select between node 3- node 8- nodes 4
Link as the link between port 6 and port 7（Common link between node 3 and node 4）Backup link.If matched somebody with somebody
Put the priority of the priority of subring 4 higher than subring 3, then when the link in subring 3 is complete, and the link in subring 4 it is complete when,
The node 4 of node 3/ needs to select the link between node 3- node 9- nodes 4 as the link between port 6 and port 7（Node
Common link between 3 and node 4）Backup link.
Step 402, the first main link when detecting common link and breaking down, the public affairs blocked on the first main link
The control VLAN and data vlan of common link corresponding ports, and open the corresponding marginal end of backup link on the first main link
The control VLAN of mouth, and the first message is sent to the subring host node on backup link by edge port, first message is used
The data vlan of secondary port is opened in subring host node is notified；By subring host node after the first message is received, secondary end is opened
The data vlan of mouth.
Specifically, the first main link is when detecting common link and breaking down, if there is currently the common link
Corresponding backup link, then the first main link is no longer to main ring host node transmission LinkDown（Link failure）Message, but
The control VLAN and data vlan of the common link corresponding ports blocked on the first main link, and open on the first main link
The corresponding edge port of backup link control VLAN so that main ring host node can before the timeout receive its hello packet.
Additionally, the first main link can also pass through edge port sends the first message to the subring host node on backup link（Such as
Linkdown messages, the Linkdown messages are used for the data vlan for notifying subring host node to open secondary port）；By the main section of subring
Point opens the data vlan of secondary port after Linkdown messages are received.Based on this, the first main link and the second main ring section
Backup link between point will take over common link, become new common link.Further, it is public if there is currently no this
The corresponding backup link of link, then still notify that main ring host node carries out link switching using existing Linkdown mechanism, should
Processing procedure will not be described here.
In the embodiment of the present invention, the first main link opens the corresponding edge port of backup link on the first main link
Control VLAN after, the first main link also need to by edge port to subring host node send the second message（Such as
CommonFDB messages）, and second message be used for notify subring host node stop loop detection is carried out to subring；By subring master
After the second message is received, stopping carries out loop detection to node to subring, so as to avoid subring host node from carrying out subring
There is mistake when detecting in loop.
Under the application scenarios shown in Fig. 3, node 1 breaks down detecting the common link between port 2 and port 3
When, the control VLAN of port blocked 2 and data vlan, and open the control VLAN of edge port 13, by edge port 13 to
Node 5 sends Linkdown messages, and the Linkdown messages are used to notify that node 5 opens the data vlan of secondary port；Node 5 exists
After receiving Linkdown messages, the data vlan of secondary port is opened.This exterior node 1 is also sent by edge port 13 to node 5
CommonFDB messages, the CommonFDB messages are used to notify that node 5 stops carrying out loop detection to subring 1；Node 5 is being received
After CommonFDB messages, stopping carries out loop detection to subring 1.
Step 403, the first main link carries out data-message transmission by backup link and the second main link.Based on upper
