- Step 1105 at the PE2 node, based on port 4, follow the method of determining the number of FEI receiving groups, because all MPLS paths that terminate with port 4 have only one branch from the source node to the sink node (that is, step Branch 1) described in 1101, so a FEI receiving group 1 is created, as shown by the solid ellipse on the PE2 node in Figure 12.
- Step 1106 at the PE2 node, bind all MPLS paths on branch 1 where port 4 is located to the FEI receiving group 1 created in step 1105.
- Step 1107 At the PE3 node, based on port 5, follow the method of determining the number of FEI receiving groups, because all MPLS paths that terminate with port 5 have only one branch from the source node to the sink node (ie step Branch 2) described in 1101, so a FEI receiving group 2 is created, as shown by the solid ellipse on the PE3 node in Figure 12.
- Step 1109 At node P, if an error code is detected on port 1, step 1110 is executed; otherwise, error detection is continued.
- Step 1110 At the P node, find the FEI sending group 1 associated with port 1, and send the FEI message to the FEI message sending path 1 and the FEI message sending path 2 in the FEI sending group 1.
- Step 1111 At the PE2 node, after receiving the FEI message sent by the P node, it finds the bound FEI receiving group 1 according to the FEI message sending path 1 of the received FEI message, and saves the Node ID in the message and the corresponding For bit error rate, go to step 1112.
- Step 1112 at the PE2 node, copy the bit error rate received in step 1111 to all MPLS paths bound in the FEI receiving group 1.
- the error rate of all MPLS paths bound in the FEI receiving group 1 is cleared.
- the above steps 1111-1112 describe the processing steps after the PE2 node receives the FEI message. After the PE3 node receives the FEI message, the processing steps are similar to this, and will not be repeated here. Similarly, the processing steps that the FEI receiving group 2 on the PE3 node does not receive an FEI message within the timeout time of the next SD alarm detection are similar to the previous paragraph, and will not be repeated here.
- each MPLS path can determine whether to generate or disappear a signal degradation SD alarm according to the total bit error rate of the physical branch corresponding to each MPLS path.
- FIG. 13 is a schematic flowchart of a processing method for bit error rate detection according to another embodiment of the present invention. This embodiment is applied to the networking architecture shown in FIG. 14.
- the method includes:
- Step 1301 on the physical link PE1->P1->P2->PE2 (the P1 node is connected to PE1 through port 1, the P2 node is connected to P1 through port 2, and the PE2 node is connected to port 3 through port 3.
- P2 connection Create multiple MPLS paths, as indicated by the dashed line with arrows in Figure 14; and enable error detection on port 1 and port 2.
- the Node ID of the P1 node is A
- the Node ID of the P2 node is B
- Step 1302 at the P1 node, create FEI sending group 1 based on port 1, as indicated by the dotted ellipse of the P1 node in FIG. 14.
- Step 1303 at the P1 node, bind all MPLS paths passing through port 1 to FEI sending group 1.
- Step 1304 At the P1 node, according to the method for determining the number of MPLS paths used to send FEI packets in the FEI sending group, because the sink node PE2 that can be reached from port 1 of the P1 node has only one branch, so from In step 1303, it is bound to all MPLS paths in FEI sending group 1, electing or randomly selecting an MPLS path as FEI message sending route 1 for sending FEI messages.
- the above steps 1302-1304 describe how P1 creates the FEI sending group and the elements it needs.
- the method for P2 to create the FEI sending group is similar to this, so I won’t repeat them here, assuming that the FEI sending group created by P2 is an FEI sending group. 2.
- the elected or randomly selected MPLS path for sending FEI messages is the FEI message sending path 2 (on the same branch, different P nodes can choose the same MPLS path as the FEI message sending FEI messages Path, you can also select different MPLS paths. In this embodiment, different MPLS paths are selected.
- the PE sink node receives the FEI message processing steps, and sends the FEI message selected by the P node The sending path of the FEI message is irrelevant).
- Step 1306 At the PE2 node, bind all MPLS paths on the branch where port 3 is located to the FEI receiving group 1 created in step 1305.
- Step 1307 At the P1 node, if an error code is detected on port 1, step 1308 is executed, otherwise, error detection is continued.
- Step 1309 After the PE2 node receives the FEI message sent by the P1 node, it finds the bound FEI receiving group 1 according to the FEI message sending path 1 of the received FEI message, and saves the Node ID in the message (A) And the corresponding bit error rate, go to step 1310.
- Step 1310 At the PE2 node, copy the bit error rate received in step 1309 to all MPLS paths bound in the FEI receiving group 1.
- Step 1311 At the P2 node, if an error code is detected on port 2, step 1312 is executed, otherwise, error detection is continued.
- Step 1312 At the P2 node, find the FEI sending group 2 associated with port 2, and send the FEI message to the FEI message sending path 2 in the FEI sending group 2.
- Step 1313 After the PE2 node receives the FEI message sent by the P2 node, it finds the bound FEI receiving group 1 according to the FEI message sending path 2 of the received FEI message, and saves the Node ID (B) in the message And the corresponding bit error rate, go to step 1314.
- Step 1314 At the PE2 node, add the error rate of the Node ID (B) received in step 1313 and the error rate of the Node ID (A) received in step 1309 to obtain the total of FEI receiving group 1. Bit error rate, copy the total bit error rate to all MPLS paths bound in FEI receiving group 1.
- the reason why the processing in step 1310 is different from the processing in step 1314 is that when processing in step 1310, FEI receiving group 1 has received only one FEI message from the P1 node within the SD alarm detection timeout period.
- the key principles described here are:
- the bit error rate copied to the MPLS path bound in the FEI receiving group is the sum of the bit error rates of all Node IDs received within the SD alarm detection timeout time in the FEI receiving group.
- the error rate of all MPLS paths bound in the FEI receiving group 1 is cleared.
- steps 1307-1310 and 1311-1314 do not have a clear sequence and relationship, and may occur simultaneously, or there may be a context.
