In the public telecommunication network, OAM technology has become very important, especially for networks that need to provide quality of service guarantee, OAM technology can detect link status in real time and report the status, so as to achieve the purpose of link error management and provide fast Ability to switch links. So far, more and more manufacturers of communication equipment use Application Specific Integrated Circuits (ASICs) to realize the function of quickly detecting defect oscillations in OAM messages. Specifically, after the hardware detects the defect of the OAM message, it reports to the co-processor (Co-processor) through an interrupt mode, and the co-processor reads the corresponding defect information and related registers, and then notifies the upper layer application module to perform the operation of the protocol layer. However, the above-mentioned measures have the following technical problems: when OAM defect oscillation occurs, the hardware reports a large number of interrupts to the coprocessor, thereby wasting a large amount of coprocessor resources, reducing the efficiency of the coprocessor and degrading the performance of the device. In addition, since the coprocessor cannot immediately process the defects detected by the hardware, and the state of defect oscillation changes in real time, the current defect information read by the coprocessor cannot provide reliable support for the upper application modules, resulting in protocol-level wrong operation.

The above method can suppress to a certain extent the oscillation alarm caused by the mismatch of OAM packet transmission period of the two devices, but the above method only proposes a method to suppress the oscillation alarm caused by the defect, and does not solve the problem caused by the defect oscillation processing at the protocol level. technical problems of incorrect operation.

Step 1100: extract the session number and session state information from the OAM detection message.

Before step 1100, the device for OAM message detection defect oscillation processing is in the power-on process, to the random access memory (RAM, Random Access Memory) and the defect information storage unit storing the OAM detection session parameter inside the OAM message detection unit Use internal RAM for initialization.

In the initialization process, the OAM message detection unit in the OAM message detection defect oscillation processing device configures the OAM detection session parameters according to the application scenario, wherein the OAM detection session parameters include: session enable bit, session detection threshold and upper limit time of arrival. The RAM inside the OAM packet detection unit is used to store OAM detection session parameters, wherein each address can be mapped to a session number. In addition, when configuring the OAM detection session parameters, the OAM packet detection unit writes the current time into the entry of the OAM detection session parameters as the initial time of timeout detection, and the initial time of timeout detection is the last arrival time.

After the initialization is completed, the detection state machine in the OAM message detection unit is started, so that the OAM message detection unit enables the OAM detection function, and starts to receive OAM detection messages from the outside of the OAM message detection defect oscillation processing system.

Further, before extracting the session number and session state information from the OAM detection message, the method further includes:

When the OAM detection message arrives within the session detection threshold, receive the OAM detection message;

When the OAM detection message does not arrive within the session detection threshold, the enabled OAM detection session is polled to determine whether the enabled OAM detection session times out.

Specifically, the OAM packet detection unit in the device for OAM packet detection defect oscillation processing performs processing according to whether the OAM detection packet arrives. If within the session detection threshold, the OAM detection message corresponding to the OAM detection session arrives at the OAM message detection unit, the OAM message detection unit updates the last arrival time of the OAM detection session to the current time for the next time Timeout detection; at the same time, the OAM message detection unit sends the session number and message arrival information to the defect information processing unit.

If within the session detection threshold, the OAM detection message corresponding to the OAM detection session does not arrive, the OAM message detection unit updates the last arrival time of the OAM detection session to the current time for the next timeout detection; The packet detection unit sends the session number and session timeout information to the defect information processing unit. Subsequently, the OAM packet detection unit sequentially performs polling detection on all enabled OAM detection sessions, and judges whether the enabled OAM detection sessions time out to determine whether to update the last arrival time or notify the defect information processing unit.

In summary, as shown in Figure 2, the OAM packet detection method performed by the OAM packet detection unit includes the following steps:

Step 1103: Poll the OAM to detect the session.

In step 1103, when the OAM detection message does not arrive within the session detection threshold, the enabled OAM detection session is polled, the OAM detection session parameters are read, and step 1104 is executed.

Step 1104: Determine whether the difference between the current time and the last arrival time is overtime.

In step 1104, calculate the difference between the current time of the enabled OAM detection session and the stored last arrival time, and determine whether the difference is greater than the configured session detection threshold, if not, then perform step 1105; if yes , then step 1106 is executed.

Step 1105: no operation, return to step 1103.

In step 1105, the OAM detection session has not timed out, so no operation is performed, and this processing ends, and step 1103 is executed to continue polling for the next OAM detection session.

Step 1106: Update the last arrival time.

In step 1106, the OAM detection session has timed out, and the last arrival time in the OAM detection session parameter is updated to the current time for use in next detection, and step 1107 is executed.

Step 1107: Send the session state information to the defect information processing unit, and this processing ends.

In step 1107, send the session number and session state information of the current time-out OAM detection session to the defect information processing unit, and this processing ends. Here, the session state information is session timeout information.

Step 1108: Read the OAM detection session parameters.

In step 1108, if the OAM detection message arrives at the OAM message detection unit, the session number in the OAM detection message is extracted, and the corresponding OAM detection session parameter stored in RAM is read according to the session number, and step 1109 is executed.

Step 1109: Determine whether the OAM detection session is enabled.

In step 1109, the OAM message detection unit judges whether the OAM detection session is enabled according to the configured enable bit, if not, execute step 1110, and if yes, execute step 1111.

Step 1110: Discard the OAM detection message, and this processing ends.

In step 1110, if the OAM detection session is not enabled, the received OAM detection message is considered invalid, the message is discarded, and this processing ends.

Step 1111: Update the last arrival time.

In step 1111, the OAM detection session is enabled, and the last arrival time in the corresponding OAM detection session parameter is updated to the current time for use in the next detection, and step 1112 is executed.

Step 1112: Send the session state information to the defect information processing unit.

In step 1112, the OAM packet detection unit sends the session number and session state information of the currently received OAM detection packet to the defect information processing unit, and this processing ends. Here, the session state information is packet arrival information.

Step 1200: After reading the corresponding defect information according to the session number, judge whether to report defect interruption according to the session state information and the defect information; or judge whether to update only the Describe the defect information.

In step 1200, after receiving the session number and session state information of the OAM detection message from the OAM message detection unit, the defect information processing unit in the device for OAM message detection defect oscillation processing reads the information in the defect information storage unit according to the session number. Corresponding defect information, then compare the current session state information with the defect information stored in the OAM detection session, and judge whether to update the defect information in the defect information storage unit or report the defect interruption to the external OAM packet detection defect oscillation processing device.

In step 1200, the judging whether to report defect interruption according to the session state information and the defect information includes:

When the session status information is message arrival information, judge the latch status bit and the real-time status bit, wherein the defect information includes the latch status bit and the real-time status bit;

When the latch status bit is a defect exit status and the real-time status bit is a defect generation status, report the defect interrupt; or,

When the session status information is session timeout information, judge the latch status bit and the real-time status bit;

When the latch status bit and the real-time status bit are the defect exit status, report the defect interrupt.

In step 1200, the judging whether to update only the defect information according to the session state information and the defect information includes:

When the session state information is the packet arrival information, judge the latch state bit and the real-time state bit;

When the latch status bit and the real-time status bit are the defect generation status, setting the real-time status bit to the defect exit status; or,

When the session state information is the session timeout information, judge the latch state bit and the real-time state bit;

When the latch status bit is the defect generation status and the real-time status bit is the defect exit status, the real-time status bit is set to the defect generation status.

In step 1203, after the defect information storage unit returns the defect information, the defect information processing unit judges whether the received session state information is message arrival information, that is, whether it is 0, if not, then execute step 1204, if yes, execute step 1211.

Step 1204: Determine whether the latch status bit (S_state) is 0.

In step 1210, both the latch status bit and the real-time status bit in the defect information of the OAM detection session are defect exit states, indicating that the current OAM detection session has not generated defect interruption, so the real-time status bit and the latch status bit are updated, namely S_state and C_state are both set to 1, and a defect interrupt is reported to the processor for OAM message detection defect oscillation processing, and this processing ends.

Step 1211: Determine whether S_state is 0.

In step 1211, the current OAM detection session is in the packet arrival state, and judge whether the latched state bit S_state in the returned defect information is 0, if not, execute step 1212, and if yes, execute step 1215.
