[0002] Operations, Administration and Maintenance (OAM) is a management and maintenance protocol for network devices. It can monitor and warn device status by sending and receiving different types of messages. If a device is found to have a fault or abnormality, OAM will report the alarm information to the Network Management System (NMS) to help operation and maintenance personnel find and solve the problem in a timely manner. With the gradual development of 5G technology, users' requirements for high bandwidth, low latency and high stability of the network are gradually increasing, and the OAM alarm detection function is an important means to improve the stability of network equipment.

[0003] At present, the OAM alarm implementation of mainstream switching chips is designed according to fixed parsing logic, and only supports common OAM alarm types, such as: Loss of Continuity (LOC), Remote Defect Indication (RDI), Bidirectional Forwarding Detection (BFD), Diagnostic (DIAG), etc. This implementation is generally designed according to the requirements of standard protocols and can only meet the basic OAM alarm detection needs of users. However, with the continuous changes in user needs, new alarm types and requirements are constantly being proposed, and the solidified alarm detection mechanism cannot meet the ever-changing new alarm detection needs.

[0004] In summary, there is no good solution to the above problems. Summary of the invention

In one example, the transmission device 16 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0026] In one embodiment of the present application, an OAM alarm detection method is provided, which is applied to a switch or similar network equipment and can be specifically executed by a switching chip inside the switch.

[0027] Figure 2 is a flow chart of an OAM alarm detection method according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0028] Step S202, according to the detection type field of the message, entering the OAM detection process corresponding to the detection type field, wherein the OAM detection process includes a preset custom detection process;

[0029] Step S204, when the OAM detection process is the custom detection process, obtaining an enabling control type field and a detection configuration field corresponding to the detection type field;

[0030] Step S206: determine a target detection result according to the enable control type field and the detection configuration field.

[0031] In an embodiment of the present application, through the above-mentioned steps S202 to S206, the problem that the alarm detection mechanism in the related technology is solidified and cannot meet the ever-changing new alarm detection needs can be solved. Starting from the logical design of alarm detection, independent custom alarm detection logic judgment is added and user configuration is supported, thereby improving the flexibility of alarm detection.

[0032] In some embodiments, the OAM detection process may further include a preset fixed detection process to achieve compatibility with traditional OAM detection.

[0033] In some embodiments, the preset fixed detection process (i.e., traditional OAM detection) includes but is not limited to the following detection methods:

[0034] Connectivity Fault Management (CFM) is used to detect and locate network connection failures. It monitors network connections and locates fault points by sending and receiving detection frames.

[0035] Transparent OAM (TPOAM) is used for performance monitoring and fault management at the transport layer or data link layer. It monitors and controls data flows by embedding OAM information in the transport layer protocol header.

[0036] Bidirectional Forwarding Detection (BFD) is used to quickly detect and notify router or link failures in the network by periodically sending and receiving small probe messages on the network path.

[0037] In some embodiments, before entering the OAM detection process corresponding to the detection type field according to the detection type field of the message in step S202, the method further includes:

[0038] Step S200: receiving a message, and adding the detection type field to the system header of the message.

[0039] In this embodiment, the detection type field is used to indicate whether the message performs the fixed detection process or the custom detection process.

[0040] In an exemplary embodiment, when the number of fixed detection processes is 3, the value of the detection type field (custom_alm_type) can use 0 to 2 to represent the above three fixed detection processes, and use a value other than 0 to 2 to represent a custom detection process, for example, custom_alm_type = 0 represents the CFM detection process, custom_alm_type = 1 represents the TPOAM detection process, custom_alm_type = 2 represents the BFD detection process, and custom_alm_type = 3 represents the user-configured custom detection process. This application does not limit the number of detection types and the field values ​​corresponding to each detection type.

[0041] In this embodiment, the user can flexibly configure the value of the detection type field, thereby improving the flexibility of alarm detection. When a new alarm detection requirement is added, a new detection type field value can be directly added without changing the original alarm detection logic.

[0042] In some embodiments, step S202 may include: determining a corresponding OAM detection type according to a value of the detection type field, and entering an OAM detection process corresponding to the OAM detection type, wherein the OAM detection type includes at least one preset custom detection type.

[0043] In another embodiment, the OAM detection type further includes at least one preset fixed detection type, such as one or a combination of CFM detection, TPOAM detection or BFD detection.

[0044] In some embodiments, step S204 may include: acquiring the enable control type field and the detection configuration field from a register corresponding to the OAM detection type, wherein each of the custom detection types corresponds to at least one group of the registers.

[0045] In some embodiments, each group of registers includes at least one register, and each register stores the values ​​of an enable control type field and a detection configuration field corresponding to a custom detection type.

[0046] In the embodiment of the present application, custom configuration of OAM detection can be achieved by configuring the custom detection type, enable control type field and detection configuration field of the register.

[0047] In some embodiments, step S206 may also include: when each of the custom detection types corresponds to multiple groups of registers, obtaining a register matching relationship from a ternary content addressable memory (TCAM) according to a preset matching relationship mask value, wherein the register matching relationship includes AND and OR; determining a target detection result according to the register matching relationship and multiple groups of detection configuration fields, wherein the multiple groups of detection configuration fields are obtained respectively from the multiple groups of registers.

[0048] In this embodiment, a combination configuration of multiple groups of matching conditions can be achieved by setting the register matching relationship, which can further improve the flexibility of alarm detection compared to the matching method of a fixed set of conditions.

[0049] In some embodiments, the global enable control type under custom detection may include incoming packet detection, polling detection, and alarm disappearance. Incoming packet detection is used to detect whether a specified position in a message packet carries specified information, and if so, an alarm is generated. Polling detection is used to detect whether a specified message type is received within a certain period, and if not, an alarm is generated. Alarm disappearance is used to eliminate the alarm generated in polling detection.

[0050] In some embodiments, when the enable control type field includes an incoming packet detection enable control field, the detection configuration field includes: an alarm offset, an alarm length, an alarm mask, and an alarm expected value, wherein the alarm expected value is configured based on the session number of the message.

[0051] In some embodiments, step S206 may include the following steps:

[0052] Step S2061-1, judging whether to enter the incoming packet detection process according to the incoming packet detection enable control field;

[0053] Step S2061-2, if the judgment result is yes, obtaining a target alarm value from the message according to the alarm offset, the alarm length and the alarm mask;

[0054] Step S2061-3: When the target alarm value is consistent with the alarm expected value, generate an incoming packet detection alarm corresponding to the alarm expected value.

[0055] In some embodiments, after step S2061-3, the method further includes the following steps:

[0056] Step S2061-4, acquiring a corresponding alarm elimination period and an alarm elimination multiple from a target session table according to the detection type field, wherein the target session table is configured based on the session number of the message;

[0057] Step S2061-5, determining the product of the alarm elimination period and the alarm elimination multiple as the elimination time of the incoming packet detection alarm;

[0058] Step S2061-6: if no message corresponding to the incoming packet detection alarm is received within the cancellation time of the incoming packet detection alarm, cancel the incoming packet detection alarm.

[0059] In this embodiment, the target session table is configured based on the OAM session number (OAMID), and the alarm elimination conditions of the packet detection alarm are configured in the session table, which can be achieved by adding a detection type field and the corresponding alarm elimination cycle and alarm elimination multiple in the traditional OAM session table.

[0060] In some embodiments, when the enable control type field includes a polling detection enable control field or an alarm elimination enable control field, the detection configuration field includes: an operation code offset, an operation code length, and an operation code expected value.

[0061] In some embodiments, step S206 may include the following steps:

[0062] Step S2062-1, judging whether to enter the polling detection process according to the polling detection enable control field;

[0063] Step S2062-2, if the judgment result is yes, obtaining a target operation code value from the message according to the operation code offset and the operation code length;

[0064] Step S2062-3, when the target operation code value is consistent with the operation code expected value, perform polling detection according to the target operation code value, and obtain a polling detection result corresponding to the message.

[0065] In this embodiment, through polling detection, a LOC alarm of a corresponding message, such as CCM LOC / BFD LOC, etc., may be generated when certain designated messages are not received within a certain period.

[0066] In some embodiments, performing polling detection according to the target operation code value and obtaining a polling detection result corresponding to the message may further include the following steps:

[0067] Step S2062-4, acquiring a corresponding polling period and a polling multiple from a target session table according to the detection type field, wherein the target session table is configured based on the session number of the message;

[0068] Step S2062-5, determining the product of the polling cycle and the polling multiple as the generation time of the polling detection alarm;

[0069] Step S2062-6: If the target message corresponding to the target operation code value is not received within the generation time of the polling detection alarm, a polling detection alarm corresponding to the target message is generated.

[0070] In this embodiment, the alarm condition of the polling detection is configured in the session table, which can be achieved by adding a detection type field and a corresponding polling cycle and polling multiple in the traditional OAM session table.

[0071] In some embodiments, after generating a polling detection alarm corresponding to the target message in step S2062-6, the method further includes the following steps:

[0072] Step S2062-7, acquiring the corresponding polling alarm elimination period and polling alarm elimination multiple from the target session table according to the detection type field;

[0073] Step S2062-8, determining the product of the polling alarm elimination period and the polling alarm elimination multiple as the elimination time of the polling detection alarm;

[0074] Step S2062-9, after waiting for the elimination time of the polling detection alarm, eliminate the polling detection alarm corresponding to the target message.

[0075] In this embodiment, the alarm elimination condition of the polling detection is configured in the session table, which can be achieved by adding a detection type field and a corresponding polling alarm elimination period and polling alarm elimination multiple in the traditional OAM session table.

[0076] In an exemplary embodiment, the polling detection enable control field and the alarm elimination enable control field can be configured separately, and whether to enter the alarm elimination process can be determined based on the alarm elimination enable control field. If so, the alarm elimination process of the polling detection alarm in the above steps S2062-7 to S2062-9 is executed.

[0077] Although the related art can realize the new alarm detection function by redesigning the chip code logic, the versatility is poor, and the chip takes a long time from design to production. Through the embodiment of the present application, it can be compatible with the traditional alarm detection process, and provide good support and compatibility for the introduction of new alarms, realizing a more flexible alarm detection configuration method, which can better adapt to the ever-changing product needs.

[0078] Figure 3 is a schematic diagram of the structure of the OAM message format according to an embodiment of the present application, such as Figure 3 As shown, the chip OAM module parses the received message and adds a custom detection mark in the system header of the OAM message.

[0079] In this embodiment, the detection type field (custom_alm_type) can be added to the header type (head_type), and 0 to 2 are used to indicate a fixed detection type, and a value other than 0 to 2 is used to indicate a newly added custom detection type.

[0080] In this embodiment, a specific type value may be configured in the chip register, and when the value of the detection type field matches the type value in the chip register, the corresponding type alarm detection logic is executed.

[0081] Figure 4 is a flow chart of incoming packet detection according to an embodiment of the present application, such as Figure 4 As shown, the process includes the following steps:

[0082] Step S401, determining whether the packet header type (pkt_head_type) is a custom detection type (custom_type_n);

[0083] Step S402, determine whether the incoming packet detection enable control field (custom_headtype_coming_en) is enabled, and if enabled, enter the incoming packet detection process;

[0084] Step S403, obtaining a custom target alarm value (custom_alm_value) according to the detection configuration field;

[0085] Step S404, determining whether the target alarm value (custom_alm_value) is consistent with the alarm expected value (custom_alm_exp);

[0086] Step S405: When the target alarm value is consistent with the alarm expected value, a custom incoming packet detection alarm (custom_alm) is generated.

[0087] In this embodiment, if the packet header type in step S401 is not a user-defined detection type, the fixed detection process is entered.

[0088] In this embodiment, if the judgment result of any step from step S402 to step S404 is no, or the target alarm value is not extracted, then no incoming packet detection alarm corresponding to the user-defined detection type is generated.

[0089] In this embodiment, the configuration information corresponding to the incoming packet detection (ie, the detection configuration field) includes: an alarm offset (custom_alm_offset), an alarm length (custom_alm_len), an alarm mask (custom_alm_mask), and an alarm expected value (custom_alm_exp).

[0090] In this embodiment, the alarm offset is used to indicate the position of the message from which the match starts, the alarm length is used to indicate the length of the match, and the alarm mask is used to indicate the mask of the match. Step S403 can match the received message content according to the above three configuration information, and then extract the target alarm value. Due to the addition of the alarm mask, fuzzy matching of the target alarm value can be achieved, which improves the flexibility of matching.

[0091] In some embodiments, the expected alarm value in step S404 may be configured for an OAM message session ID (OAMID), and different OAMIDs may be configured with different expected alarm values.

[0092] In some embodiments, when the target alarm value is consistent with the alarm expected value, step S405 generates a custom alarm corresponding to the alarm expected value. If there are multiple alarm expected values, multiple custom alarm fields can also be added to the alarm table item.

[0093] In this embodiment, the alarm elimination of the incoming packet detection can be performed according to the alarm elimination period (custom_alm_coming_clr_period) and the alarm elimination multiple (custom_alm_coming_clr_dm) in the session table. The product of the alarm elimination period and the alarm elimination multiple is determined as the elimination time of the incoming packet detection alarm. If no message of the custom type is received within the elimination time, the custom alarm elimination is triggered.

[0094] Figure 5 is a flowchart of polling detection according to an embodiment of the present application, such as Figure 5 As shown, the process includes the following steps:

[0095] Step S501, determining whether the packet header type (pkt_head_type) is a custom detection type (custom_type_n);

[0096] Step S502, determine whether the polling detection enable control field (custom_alm_polling_en) is enabled, and if enabled, the polling detection process is entered;

[0097] Step S503, obtaining a custom target opcode value (custom_opcode_value) according to the detection configuration field;

[0098] Step S504, determining whether the target opcode value (custom_opcode_value) is consistent with the opcode expected value (custom_opcode_exp);

[0099] Step S505, when the target operation code value is consistent with the expected operation code value, polling detection is performed on the message packets corresponding to the target operation code value according to the session table information;

[0100] Step S506: Generate a customized polling detection alarm.

[0101] In this embodiment, if the packet header type in step S501 is not a user-defined detection type, the fixed detection process is entered.

[0102] In this embodiment, if the judgment result of any step from step S502 to step S504 is no, or the target operation code value is not extracted, the polling detection process ends.

[0103] In this embodiment, an operation code (opcode) may be used to indicate a message type, and a designated message targeted by the polling detection is determined according to a target operation code value.

[0104] In this embodiment, the configuration information corresponding to the polling detection includes: an opcode offset (custom_alm_poll_opcode_offset), an opcode length (custom_alm_poll_opcode_len), and an opcode expected value (custom_opcode_exp).

[0105] In this embodiment, the opcode offset is used to indicate the position of the message from which the match starts, and the opcode length is used to indicate the length of the match. Step S503 can match the received message content according to the above two configuration information, and then extract the target opcode value.

[0106] In this embodiment, polling detection is also performed according to the polling period (custom_alm_polling_period) and the polling multiple (custom_alm_polling_dm) in the session table. The two are multiplied to obtain the generation time of the polling detection alarm. If the specified message is not received within this time, this type of LOC alarm is triggered.

[0107] Figure 6 is a flowchart of alarm elimination according to an embodiment of the present application, such as Figure 6 As shown, the process includes the following steps:

[0108] Step S601, determining whether the packet header type (pkt_head_type) is a custom detection type (custom_type_n);

[0109] Step S602, determine whether the alarm elimination enable control field (custom_alm_clr_en) is enabled, and if enabled, the alarm elimination process is entered;

[0110] Step S603, obtaining a custom target opcode value (custom_opcode_value) according to the detection configuration field;

[0111] Step S604, determining whether the target opcode value (custom_opcode_value) is consistent with the opcode expected value (custom_opcode_exp);

[0112] Step S605: when the target operation code value is consistent with the expected operation code value, the message packet corresponding to the target operation code value is polled and detected according to the session table information;

[0113] Step S606, eliminating the customized polling detection alarm.

[0114] In this embodiment, if the packet header type in step S601 is not a user-defined detection type, the fixed detection process is entered.

[0115] In this embodiment, if the judgment result of any step from step S602 to step S604 is no, or the target operation code value is not extracted, the alarm elimination process of the polling detection is terminated.

[0116] In this embodiment, the configuration information corresponding to the alarm elimination includes: an opcode offset (custom_alm_poll_opcode_offset), an opcode length (custom_alm_poll_opcode_len), and an opcode expected value (custom_opcode_exp).

[0117] The alarm elimination process in the embodiment of the present application is aimed at the alarm elimination of the polling alarm, and the generation and elimination of the polling alarm can share the same set of configuration information.

[0118] In this embodiment, the opcode offset is used to indicate the position of the message from which the match starts, and the opcode length is used to indicate the length of the match. Step S603 can match the received message content according to the above two configuration information, and then extract the target opcode value.

[0119] In this embodiment, the polling detection alarm elimination also needs to be performed according to the polling alarm elimination period (custom_alm_clr_period) and the polling alarm elimination multiple (custom_alm_clr_cnt) in the session table. The two are multiplied to obtain the elimination time of the polling detection alarm. When a specified message is received within this time, the corresponding polling detection alarm is eliminated.

[0120] In one embodiment, the newly added custom OAM detection standard is as follows: for OAM messages with an operation code of 70, a remote defect indication (RDI) alarm is triggered when a certain offset position is 1, and a signal degrade (SD) alarm is triggered when a certain position is 1. If no message is received within 5 cycles, a LOC alarm is reported (polling detection). If any correct message is received within 5 cycles, the alarm disappears.

[0121] In this embodiment, according to the user-defined OAM detection standard, the user configures the OAM message header, register, and OAM session table as shown below.

[0122] Table 1 shows the global custom detection type, which is configured in the OAM packet header. The configuration value can be any value except the value corresponding to the fixed detection type.
