[0002] In the current network environment, problems such as fiber degradation, fiber damage, fiber contamination, optical module damage, and optical module degradation occur frequently.

Taking voice services as an example, bit errors will cause noise, voice call delays, and dropped calls, which will greatly affect the customer experience.

[0003] To address the bit error rate issue, the industry has proposed a forwarding plane performance degradation protection switching scheme. Specifically, it employs physical link layer SD detection for performance degradation detection and uses extended OAM CCM type messages as bit error indicators (EI) to generate performance degradation messages. For SR-TP tunnels, the extended OAM CCM messages are forwarded downstream. Downstream PE devices, upon receiving these messages, trigger protection switching based on their APS status.

[0041] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0042] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0043] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0044] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0045] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0046] like Figure 1 As shown, an embodiment of the present invention provides a routing processing method applied to a service node. This routing processing method includes, but is not limited to, the following steps:

[0047] Step 11: Obtain the first message carrying error information of the node or link.

[0048] Collect node or link error information to form a message with error information. The error information includes at least one of the following: error location, error type identifier, error measurement method, error identifier, and error rate.

[0049] Step 12: Send the first message to the error handling module.

[0050] Step 13: Execute the corresponding routing switch according to the protection switching command.

[0051] Execute protection switching commands initiated due to bit error requirements. These switching commands are initiated when protection switching is determined to be necessary based on bit error information, or they are sent by the management system to indicate the routing path of the bit error policy corresponding to the bit error information. In other words, the management of switching commands can be initiated through a separate management system or through the management module on the service node.

[0052] Optionally, in one embodiment of the present invention, the first message includes at least one of the following indication fields:

[0053] The first indication field used to indicate the location of the error;

[0054] The second indicator field is used to indicate the type of error;

[0055] The third indication field is used to indicate the error measurement method;

[0056] The fourth indicator field is used to indicate error flags;

[0057] The fifth indicator field is used to indicate the bit error rate.

[0058] Optionally, such as Figure 2 As shown, the first indicator field, the second indicator field, the third indicator field, or the fourth indicator field each occupy 1 bit; the fifth indicator field occupies 20 bits.

[0059] Specifically, the first message can be called the bit error rate message. This message carries error information including error location, error type identifier, error measurement method, error identifier, and bit error rate. For example... Figure 2 As shown, in the signaling structure of the bit error rate message,

[0060] The first indicator field L occupies 1 bit and is used to indicate the location of the error, such as whether the error rate is a node error or a link error.

[0061] The second indicator field E occupies 1 bit and is used to indicate the type of error, such as: error before FEC correction, error after FEC correction, etc.

[0062] The third indicator field M occupies 1 bit and is used to indicate the error measurement method, such as whether it is a CRC check error or an optical layer BER.

[0063] The fourth indicator field P occupies 1 bit and is used to indicate the error flag. For example, the error flag is used to indicate the relationship between the error rate and the error threshold.

[0064] The fifth indicator field, BER, occupies 20 bits and is used to indicate the bit error rate, such as the bit error rate of a node or link.

[0065] By including the link error rate in the bit error rate message, and optionally including the device link error identifier, which can represent the relationship between the device's bit error rate and the configured bit error threshold, the service node can perform routing based on the bit error information in the topology information. The error identifier can be carried and transmitted, and the management and control system can initiate protection switching trigger commands for the corresponding link based on the error identifier, thereby achieving pre-emptive control of signal performance degradation.

[0066] Optionally, service nodes can autonomously determine whether to initiate protection switching based on error information. Furthermore, service nodes can determine whether to perform protection switching based on error information and a primary relationship, where the primary relationship is the relationship between the link where the service node resides and the service. In other words, protection switching can be initiated not only based on node and link error exceeding limits, but also based on the relationship between the link where the node resides and the service and the tunnel. It is worth noting that switching can only be initiated based on link degradation when a tunnel is established to carry the service.

[0067] Optionally, step 11 may be followed by sending the first message to other nodes.

[0068] Service nodes can send this first message to other nodes via protocols such as IGP / OSPF / ISIS.

[0069] Optionally, step 12 includes: sending the first message to the error handling module via the BGP-LS / EBGP protocol.

[0070] Optionally, the first message can be a link status message, or the first message can be a node status message. That is, error information can be sent as status information.

[0071] Border Gateway Protocol-Link State (BGP-LS) is a method for collecting network topology information, making the process simpler and more efficient. BGP-LS extends the BGP Path Attribute attribute, adding network topology information to BGP route attributes and transmitting it through BGP to achieve global network topology collection.

[0072] This invention provides a new type of node and link bit error rate message. By extending protocols, such as BGP node and link attributes, the link bit error rate message is added to the corresponding protocol node and link object attributes, and reported to the controller through protocols such as BGP-LS, thereby realizing the collection and updating of global topology bit error attributes.

[0073] In the routing processing method of this invention, error information is used to monitor the signal performance degradation of the link and determine the routing path corresponding to the error policy. This improves the quality of the underlying links of the service and thus enhances the guarantee of the service SLA. Issuing routing switching commands through the management system helps devices that do not support error indication switching to protect against link errors, expanding the scope of signal performance degradation protection and improving network quality.

[0074] The routing processing method of this embodiment of the invention has been described above from the perspective of the business node. The routing processing method of the error processing module side will be further explained below with reference to the accompanying drawings.

[0075] like Figure 3 As shown, an embodiment of the present invention provides a routing processing method applied to an error processing module. This routing processing method includes, but is not limited to, the following steps:

[0076] Step 31: Receive the first message carrying error information of the node or link.

[0077] The error information includes at least one of the following: error location, error type identifier, error measurement method, error identifier, and error rate.

[0078] Step 32: Determine the routing path for the corresponding error policy based on the error information.

[0079] The error handling module extracts and identifies error information from the first message, marks error information in the network topology, considers the routing strategy of the error policy when calculating the path, and selects the path corresponding to the error policy based on the error information.

[0080] Network topology information includes network devices, links, connectivity, bandwidth, etc. Traffic Engineering typically calculates paths based on network topology and network link status. For example, SPN uses PCEP routing, where PCE calculates paths based on network topology information collected by management and control.

[0081] Step 33: Based on the error information, determine whether protection switching is required.

[0082] The error handling module extracts error information from the message and determines whether to perform protection switching operation on the link or the link where the node is located.

[0083] Optionally, step 33 includes: determining whether protection switching is needed based on the bit error information and the first relationship, wherein the first relationship is the relationship between the routing path and the service. That is, protection switching can be initiated not only based on node and link bit error exceeding limits, but also based on the relationship between the link where the node is located and the service and tunnel. It is worth noting that switching can only be initiated based on link degradation when a tunnel is established to carry the service.

[0084] Step 34: When it is determined that protection switching is required, send a protection switching command carrying the routing path to the management system.

[0085] The error handling module notifies the control system of protection switching, and the control system then issues a command to the original node of the business path to perform the switching.

[0086] Optionally, in one embodiment of the present invention, step 33 includes, but is not limited to, the following two implementation methods:

[0087] Method 1: Determine whether protection switching is required based on the error identifier in the error information.

[0088] Specifically, the protection switching action can be directly determined through error codes.

[0089] Method 2: Determine whether protection switching is needed based on the bit error rate in the bit error information.

[0090] By extracting and analyzing the bit error rate, a decision is made as to whether protection switching is necessary.

[0091] Optionally, the routing processing method in this embodiment of the invention further includes: generating an operation and maintenance report indicating network quality based on the bit error information. That is, the bit error processing module uses the bit error information to generate an intelligent operation and maintenance report analyzing network quality, etc.

[0092] Optionally, the first message includes at least one of the following indication fields:

[0093] The first indication field used to indicate the location of the error;

[0094] The second indicator field is used to indicate the type of error;

[0095] The third indication field is used to indicate the error measurement method;

[0096] The fourth indicator field is used to indicate error flags;

[0097] The fifth indicator field is used to indicate the bit error rate.

[0098] Optionally, such as Figure 2 As shown, the first indicator field, the second indicator field, the third indicator field, or the fourth indicator field each occupy 1 bit; the fifth indicator field occupies 20 bits.

[0099] Optionally, the first message is a link status message, or the first message is a node status message.

[0100] In the routing processing method of this invention, error information is used to monitor the signal performance degradation of the link and determine the routing path corresponding to the error policy. This improves the quality of the underlying links of the service and thus enhances the guarantee of the service SLA. Issuing routing switching commands through the management system helps devices that do not support error indication switching to protect against link errors, expanding the scope of signal performance degradation protection and improving network quality.

[0104] The first sending unit 420 is used to send the first message to the error processing module;

[0105] The processing unit 430 is used to execute corresponding routing switching according to the protection switching command sent by the control system.

The switching command is used to indicate the routing path of the error policy corresponding to the error information.
