Embodiment
For problems of the prior art, the embodiment of the present invention provides a kind of data message transmission method based on subring link, the method is applied to comprise in the RRPP network of main ring and subring, and on main ring, under adjacent two main links, hang corresponding subring, on main ring, two adjacent main links are respectively the Edge node and assistant edge node of subring.The application scenarios schematic diagram that the Fig. 3 of take is the embodiment of the present invention, node 1, node 2, node 3 and node 4 form main ring.Node 1 and node adjacent on main ring are hung corresponding subring 1 for 2 times, and node 1, node 2, node 5 form subring 1; Node 1 is fringe node, and node 2 is assistant edge node, or node 1 is assistant edge node, and node 2 is fringe node; In addition, node 5 is subring host node.Node 2 and node adjacent on main ring are hung corresponding subring 2 for 3 times, and node 2, node 3, node 6, node 7 form subring 2; Node 2 is fringe node, and node 3 is assistant edge node, or node 2 is assistant edge node, and node 3 is fringe node; In addition, node 6 or node 7 are subring host node.Node 3 and node adjacent on main ring are hung corresponding subring 3 and subring 4 for 4 times, and node 3, node 4, node 8 form subring 3, and node 3, node 4, node 9 form subring 4; In subring 3, node 3 is fringe node, and node 4 is assistant edge node, or node 3 is assistant edge node, and node 4 is fringe node; In addition, node 8 is subring host node; In subring 4, node 3 is fringe node, and node 4 is assistant edge node, or node 3 is assistant edge node, and node 4 is fringe node; In addition, node 9 is subring host node.
In the embodiment of the present invention, except Edge node and assistant edge node, other subring node in subring also needs the transmission node as main ring, and all subring nodes in subring are all as the transmission node of main ring under it, and adds the control VLAN of main ring.Wherein, by other subring node in subring being joined to the control VLAN of main ring, so that other subring node in subring is as the transmission node of main ring.Under the application scenarios shown in Fig. 3, for subring 1, node 5 is as the transmission node of main ring 1, and joins the control VLAN of main ring 1; For subring 2, node 6 and node 7 be as the transmission node of main ring 1, and join the control VLAN of main ring 1; For subring 3, node 8 is as the transmission node of main ring 1, and joins the control VLAN of main ring 1; For subring 4, node 9 is as the transmission node of main ring 1, and joins the control VLAN of main ring 1.
In the embodiment of the present invention, in the situation that main ring and subring are all complete, the control VLAN of the edge port on Edge node and assistant edge node is in blocked state, and fringe node need to block the control VLAN of edge port, and assistant edge node need to block the control VLAN of edge port.Further, in subring, the control VLAN of the port of other subring node is in forwarding state, and other subring node need to be opened the control VLAN of port.Under the application scenarios shown in Fig. 3, node 1 blocks the control VLAN of edge port 13, and node 2 blocks the control VLAN of edge port 14 and 26, and node 3 blocks the control VLAN of edge port 25,33 and 43, and node 4 blocks the control VLAN of edge port 34 and 44; In addition, node 5 is opened the control VLAN of port one 1 and 12, and node 6 is opened the control VLAN of port 21 and 22, and node 7 is opened the control VLAN of port 23 and 24, and node 8 is opened the control VLAN of port 31 and 32, and node 9 is opened the control VLAN of port 41 and 42.
In the embodiment of the present invention, two main links adjacent on main ring are respectively the first main link and the second main link, the Edge node and assistant edge node that on main ring, adjacent the first main link and the second main link are subring.Wherein, the first main link is relative with the second main link, and the processing procedure of the first main link is identical with the processing procedure of the second main link.Under the application scenarios shown in Fig. 3, for subring 1, the first main link, be that node 1, the second main link is node 2, or the first main link is that node 2, the second main links are node 1.For subring 2, the first main links, be that node 2, the second main links are node 3, or the first main link is that node 3, the second main links are node 2.For subring 3 or subring 4, the first main links, be that node 3, the second main links are node 4, or the first main link is that node 4, the second main links are node 3.
For convenience of description, in the embodiment of the present invention, the example that is treated to the first main link describes.
As shown in Figure 4, should comprise the following steps by the data message transmission method based on subring link:
Step 401, the first main link is selected the backup link that the first main link is corresponding with common link between the second main link.Wherein, common link is specially between the first main link and the second main link and is positioned at the link on main ring, and backup link is specially the link that is positioned in subring between the first main link and the second main link and passes through subring host node.
Under the application scenarios shown in Fig. 3, the common link that node 1 and node are 2 is the link of 3 of port 2 and ports, and the backup link that node 1 and node are 2 is the link of 2 of node 1-node 5-nodes.The common link that node 2 and node are 3 is the link of 5 of port 4 and ports, and the backup link that node 2 and node are 3 is the link of 3 of node 2-node 6-node 7-nodes.The common link that node 3 and node are 4 is the link of 7 of port 6 and ports, and the backup link that node 3 and node are 4 is the link of 4 of node 3-node 8-nodes, or the link of 4 of node 3-node 9-nodes.
In order to guarantee that the backup link of selecting can carry out data-message transmission, backup link need to be in backup upstate, i.e. backup link place subring is complete, now can carry out data-message transmission based on backup link.Wherein, when the subring at backup link place is complete, backup link is in backup upstate, and when the subring at backup link place is imperfect, backup link is in down state.
Based on this, in the embodiment of the present invention, the first main link is selected the process of the corresponding backup link of common link between the first main link and the second main link, specifically include but not limited to following mode: the first main link is when the 3rd message of receiving from subring host node, determine that the link in subring is complete, now can select being positioned in this subring and being the corresponding backup link of common link through the link of subring host node between the first main link and the second main link; The first main link is when the 4th message of receiving from subring host node, determine that the link in subring is imperfect, now can select being positioned in this subring and not being the corresponding backup link of common link through the link of subring host node between the first main link and the second main link.
Wherein, the 3rd message is specifically as follows the complete forwarding database of CompleteFDB() message, subring host node is when sending CompleteFDB message, show that the link in subring is complete, therefore the first main link, when the CompleteFDB message of receiving from subring host node, determines that the link in subring is complete.The 4th message is specifically as follows the common forwarding database of CommonFDB() message, subring host node is when sending CommonFDB message, show that the link in subring is imperfect, therefore the first main link, when the CommonFDB message of receiving from subring host node, determines that the link in subring is imperfect.
Under the application scenarios shown in Fig. 3, when node 1 is received the CompleteFDB message from node 5, determine that the link in subring 1 is complete, so node 1 link that can select 2 of node 1-node 5-nodes is as the backup link of the link (common link that node 1 and node are 2) of 3 of port 2 and ports; When node 1 is received the CommonFDB message from node 5, determine that the link in subring 1 does not complete, so node 1 link that can not select 2 of node 1-node 5-nodes is as the backup link of the link (common link that node 1 and node are 2) of 3 of port 2 and ports.
The backup link of selecting for fear of Edge node and assistant edge node is inconsistent, in the embodiment of the present invention, the first main link is selected the process of the corresponding backup link of common link between the first main link and the second main link, specifically include but not limited to following mode: when the first main link is fringe node, if the link in subring is complete, the first main link is selected being positioned in this subring and being the corresponding backup link of common link through the link of subring host node between the first main link and the second main link, and send the 5th message to the second main link, and in the 5th message, carried the subring ID of subring, afterwards, by the second main link, selecting the link that this subring ID is corresponding is the corresponding backup link of common link.In addition, when the first main link is assistant edge node, the first main link receives the 6th message from the second main link, and in the 6th message, carried backup link that the second main link selects the subring ID of corresponding subring; The first main link is after receiving the 6th message, and it is the corresponding backup link of common link that the first main link is selected link corresponding to subring ID carrying in the 6th message.
Wherein, the 5th message and the 6th message are Edge-Hello(edge health detection) message, in the embodiment of the present invention, by introduce new field in Edge-Hello message, to carry subring ID by this new field, then guarantee that the backup link of Edge node and assistant edge node selection is consistent.
Under the application scenarios shown in Fig. 3, link in subring 3 is complete, and when the link in subring 4 is complete,: node 3 can select link between node 3-node 8-node 4 as the backup link of the link between port 6 and port 7 (common link between node 3 and node 4), afterwards, node 3 is notified the subring ID of subring 3 to node 4 by Edge-Hello message, the backup link by the link between node 4 selection node 3-node 8-nodes 4 as the link between port 6 and port 7 (common link between node 3 and node 4).Or, node 3 can select link between node 3-node 9-node 4 as the backup link of the link between port 6 and port 7 (common link between node 3 and node 4), afterwards, node 3 is notified the subring ID of subring 4 to node 4 by Edge-Hello message, the backup link by the link between node 4 selection node 3-node 9-nodes 4 as the link between port 6 and port 7 (common link between node 3 and node 4).
In above-mentioned selection course, can also configure the priority of subring, with when a plurality of subrings are all complete, determine selecteed priority between each subring.Based on this, if the priority of configuration subring 3 is higher than the priority of subring 4, the link in subring 3 is complete, and when the link in subring 4 is complete, node 3/ node 4 need to select link between node 3-node 8-node 4 as the backup link of the link between port 6 and port 7 (common link between node 3 and node 4).If the priority of configuration subring 4 is higher than the priority of subring 3, the link in subring 3 is complete, and when the link in subring 4 is complete, node 3/ node 4 need to select link between node 3-node 9-node 4 as the backup link of the link between port 6 and port 7 (common link between node 3 and node 4).
Step 402, the first main link is when common link being detected and break down, the control VLAN and the data vlan that block the common link corresponding ports on the first main link, and open the control VLAN of the edge port that backup link on the first main link is corresponding, and to the subring host node on backup link, sending the first message by edge port, this first message is for notifying the data vlan of subring host node open auxiliary port; By subring host node after receiving the first message, the data vlan of open auxiliary port.
Concrete, the first main link is when common link being detected and break down, if the backup link that this common link of current existence is corresponding, the first main link no longer sends LinkDown(link failure to main ring host node) message, but block control VLAN and the data vlan of the common link corresponding ports on the first main link, and open the control VLAN of the edge port that backup link on the first main link is corresponding, so that main ring host node can be received its hello packet before overtime.In addition, the first main link can also send the first message (as Linkdown message, this Linkdown message is for notifying the data vlan of subring host node open auxiliary port) to the subring host node on backup link by edge port; By subring host node after receiving Linkdown message, the data vlan of open auxiliary port.Based on this, the backup link between the first main link and the second main link will be taken over common link, become new common link.Further, do not have backup link corresponding to this common link if current, still use existing Linkdown mechanism notice main ring host node to carry out link switching, this processing procedure does not repeat them here.
In the embodiment of the present invention, after the first main link is opened the control VLAN of the edge port that backup link on the first main link is corresponding, the first main link also needs to subring host node, to send the second message (as CommonFDB message) by edge port, and this second message is used for notifying subring host node to stop subring carrying out loop detection; By subring host node, after receiving the second message, stopped subring carrying out loop detection, thereby avoid subring host node when subring being carried out to loop detection, to occur mistake.
Under the application scenarios shown in Fig. 3, node 1 is when common link between port 2 and port 3 being detected and break down, control VLAN and the data vlan of port blocked 2, and open the control VLAN of edge port 13, by edge port 13, to node 5, send Linkdown message, this Linkdown message is for notifying the data vlan of node 5 open auxiliary ports; Node 5 after receiving Linkdown message, the data vlan of open auxiliary port.This exterior node 1 also sends CommonFDB message by edge port 13 to node 5, and this CommonFDB message is used for notifying node 5 to stop subring 1 to carry out loop detection; Node 5, after receiving CommonFDB message, stops subring 1 to carry out loop detection.
Step 403, the first main link carries out data-message transmission by backup link and the second main link.Based on above-mentioned processing, backup link will be taken over common link, become new common link, and therefore, the first main link can directly carry out data-message transmission by backup link and the second main link.
In the embodiment of the present invention, the first main link is when common link fails recovery being detected, open control VLAN and the data vlan of the common link corresponding ports on the first main link, and to subring host node, sending the 7th message by edge port, the 7th message is for notifying subring host node to block the data vlan of secondary port; By subring host node, after receiving the 7th message, block the data vlan of secondary port; And to subring host node, sending the 8th message by edge port, the 8th message is used for notifying subring host node to start subring to carry out loop detection; By subring host node, after receiving the 8th message, started subring to carry out loop detection; And, the control VLAN of the edge port on obstruction the first main link; Afterwards, the first main link will carry out data-message transmission by common link and the second main link.
Concrete, the first main link, when common link fails recovery being detected, need to recover the function of original common link.Now, the first main link is opened control VLAN and the data vlan of the common link corresponding ports on the first main link, and to subring host node, send the 7th message (as LinkUp message by edge port, for notifying subring host node to block the data vlan of secondary port), by subring host node, after receiving LinkUp message, block the data vlan of secondary port; And to subring host node, send the 8th message (as CompleteFDB message by edge port, be used for notifying subring host node to start subring to carry out loop detection), by subring host node, after receiving CompleteFDB message, started subring to carry out loop detection; And block the control VLAN of the edge port on the first main link.
Under the application scenarios shown in Fig. 3, node 1 is when the common link fails recovery detecting between port 2 and port 3, open control VLAN and the data vlan of port 2, and to node 5, sending LinkUp message by edge port 13, this LinkUp message is for notifying node 5 to block the data vlan of secondary port; Node 5, after receiving LinkUp message, blocks the data vlan of secondary port; In addition, node 1 also sends CompleteFDB message by edge port 13 to node 5, this CompleteFDB message is used for notifying node 5 to start subring 1 to carry out loop detection, and node 5, after receiving CompleteFDB message, starts subring 1 to carry out loop detection.In addition, node 1 also needs to block edge port 13.
In the embodiment of the present invention, when the first main link is main ring host node, when common link breaks down, if edge port corresponding to backup link on the first main link takes over as the secondary port of the first main link, the first main link blocks the data vlan of secondary port; When the first main link is main ring host node, when common link fails is recovered, if edge port corresponding to backup link on the first main link takes over as the secondary port of the first main link, the data vlan of the first main link open auxiliary port.
Under the application scenarios shown in Fig. 3, if node 1 is main ring host node,, when common link breaks down, if the edge port 13 on node 1 takes over as the secondary port of node 1, node 1 also needs to block the data vlan of secondary port (port one 3).Based on above-mentioned processing, further, if node 1 is main ring host node,, when common link fails is recovered, if the edge port 13 on node 1 takes over as the secondary port of node 1, node 1 also needs the data vlan of open auxiliary port (port one 3).
In sum, in the embodiment of the present invention, when the common link between main link breaks down, can carry out data-message transmission by backup link corresponding to common link, thereby avoid using SRPT status checkout mechanism to carry out main ring state-detection, the problem of then avoiding SRPT status checkout mechanism to bring.Aforesaid way can be when main ring common link breaks down, use the backup link in subring to carry out data-message transmission, guarantee the integrality of main ring, and at main ring multipoint fault (as the common link between port one and port 2 breaks down, and the common link between port 2 and port 3 breaks down, common link between port 3 and port 4 breaks down) time, the largest connected property of maintenance looped network.
