Description

Technical Field

[0001] The present invention relates to the technical field of network communication, in particular to a method for modifying a CCM detection period in Ethernet OAM and a device, electronic equipment and storage medium for implementing the modification method. Background Art

[0002] The basic function of Ethernet OAM is to detect connectivity through CCM messages. According to the IEEE 802.1ag and ITU Y.1731 standards, the CCM sending period needs to be pre-set before configuring the OAM session. The CCM message format is as follows: Figure 1 As shown, the specific content of the tag field is as follows Figure 2 As shown, the lowest 3 bits represent the sending cycle, and the valid value is 1-7. The cycle value represented by it is as follows Figure 3 As shown, periods ranging from 3.33 ms to 10 minutes can be represented.

[0003] This period is used to control the period of sending CCM messages, and is also used for connectivity detection in the receiving direction. According to the standard, if the correct CCM message is not received within 3.5 times the period time, it is considered that the OAM monitoring session has a LOC (Loss of Continuity) alarm, that is, it is considered that the link has a connectivity problem and requires the upper-layer system to perform linkage processing, such as protection switching. According to the protocol standard definition, this CCM period is pre-configured, and when receiving a message, whether the period value in the message is consistent with the pre-configured value is one of the steps in the CCM message legitimacy check. If not, an alarm of inconsistent period needs to be reported. However, in actual use, from the perspective of network management, there is an application requirement to adjust this period. If the CCM period at both ends is simply modified directly, the following two problems may occur: (1) Since both ends cannot guarantee simultaneous modification, an alarm of period value check error will be generated; (2) Since this period is also used to detect link connectivity, if it is modified improperly, a LOC alarm may be generated, further triggering other linkage behaviors of the upper-layer system. For example, if the two devices (A and B) originally used a 3.33ms sending and receiving cycle, and now want to change it to a 100ms sending and receiving cycle. After the configuration of end A is modified, end A will send CCM messages according to the 100ms sending cycle, but the receiving direction of port B has not been modified at the same time. In a short period of time, the receiving direction detection is still performed according to the 3.33ms cycle. Therefore, it is easy to trigger a LOC alarm due to the failure to receive the CCM message sent by end A for more than 3.5 times the 3.33ms cycle. The above two points are errors that administrators do not want to see when modifying the CCM detection cycle at both ends.

[0048] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0049] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0050] In the prior art, when modifying the CCM detection period, it is impossible to achieve synchronous modification of both ends of the OAM session, and error alarms will be generated, such as cycle value detection error alarms, LOC alarms, etc., which cannot meet the operation and maintenance requirements. However, the method, device, electronic device and storage medium for modifying the CCM detection period in Ethernet OAM disclosed in the present invention can achieve synchronous modification of the CCM detection period at both ends of the OAM session without generating error alarms, thus meeting the operation and maintenance requirements.

[0051] The present invention discloses a method for modifying a CCM detection period in Ethernet OAM, which is applied to an Ethernet OAM scenario. In the scenario, connectivity detection can be performed between devices through CCM messages.

[0052] The following takes the transmitting end as an example to describe in detail the method for modifying the CCM detection period in Ethernet OAM disclosed in the present invention. Figure 4 and Figure 5 As shown, the modification method includes the following steps:

[0053] S1, start the CCM detection period modification and send a period update notification message, where the period update notification message includes an enable field for identifying the detection period modification enable information;

[0054] Specifically, when modifying the CCM detection period, the transmitting end first starts the CCM detection period modification function. The CCM detection period modification function can be enabled through a corresponding instruction or through a physical switch, etc., and can be selected according to actual needs.

[0055] When the CCM detection period modification function is enabled, a period update notification message is further sent to the receiving end. The period update notification message can be used to start the notification of the OAM session CCM detection period update. In this embodiment, the period update notification message is customized based on the OAM PDU message. Figure 6 As shown, it is the OAM PDU message format, which includes an operation code (OpCode) field and a flag (Flags) field. By configuring the value of the operation code field to a preset value, such as 64, the message is identified as a periodic update notification message. At the same time, the flag field is used to customize the enable field that can identify the detection period modification enable information. The detection period enable modification information here includes the enable detection period modification information and the detection period modification information that is ready. For example, bit4 of the flag field can be used to identify whether the detection period modification is enabled, and bit5 can be used to identify whether the detection period modification is ready, which can be selected according to actual needs. For example, when bit4 is set to 1, it indicates that the detection period modification is enabled. When bit5 is set to 1, it indicates that the detection period modification is ready. Of course, in other embodiments, the existing non-periodic OAM message can also be used, and the reserved position of its flag field can be used to customize the periodic update notification message. And for the receiving end, the pre-configured operation code field value used to notify the CCM detection period modification and the corresponding tag field configurable position value can be used to jointly determine whether the OAM PDU is a notification message for the OAM session CCM detection period modification, so as to distinguish it from the original function of the operation code.

[0056] Furthermore, in order to avoid false alarms of LOC error alarms during the negotiation process of modifying the CCM detection period, the CCM reception detection may be disabled after the CCM detection period modification function is enabled.

[0057] S2, receiving a period update reply message, and determining whether the detection period modification is ready, the period update reply message including the enable field;

[0058] Specifically, after the transmitting end sends the cycle update notification message, it further waits for the receiving end to reply with a cycle update reply message. After the receiving end receives the cycle update notification message, it replies with a cycle update reply message to the receiving end, and the cycle update reply message also includes the enable field described above, and the enable field records whether the receiving end is ready to modify the detection cycle.

[0059] Furthermore, after the sending end sends the periodic update notification message, due to network abnormalities, the receiving end may not receive the periodic update notification message, and the sending end may not receive the periodic update reply message. Therefore, the sending end also periodically detects whether the periodic update reply message is received. During implementation, a timer can be used to periodically detect whether the periodic update reply message is received.

[0060] When the receiving end does not receive the periodic update notification message within a certain period of time, the timing detection mechanism of the sending end can detect this event, and then clear the update periodic notification state and restore CCM reception detection. At the same time, it reports to the upper-layer system that the peer device (receiving end) has not responded to the periodic update reply message, and the CCM detection period modification has failed. The upper-layer system can decide to conduct a new round of CCM detection modification process again.

[0061] When the sender does not receive a periodic update reply message within a certain period of time, the sender's timing detection mechanism can detect this event, and then clear the update cycle notification state and restore CCM reception detection. At the same time, it reports to the upper-layer system that the peer device has not responded to the periodic update reply message and the CCM detection period modification has failed. The upper-layer system can decide to conduct a new round of CCM detection modification process again.

[0062] In order to ensure the consistency of the confirmation processing of the CCM detection period modification, the sender still sends several period update notification messages to the receiver after the preset time (i.e. the timer times out). For the receiver, even if it is in the period learning state, the period in the CCM message it receives remains unchanged. Even if the local CCM detection period is updated, the result of the update is that the local CCM detection period remains unchanged, and the CCM detection period at both ends remains consistent, which will not have any impact on the OAM session.

[0063] When the sending end receives the period update reply message, it further determines whether the receiving end is ready to modify the detection period based on the information carried in the period update reply message. During implementation, the value of the enable field in the period update reply message can be used to determine whether the receiving end is ready to modify the detection period. For example, when bit 4 is 0 and bit 5 is 1 in the above-mentioned flag field, it indicates that the receiving end is ready to modify the detection period.

[0064] S3, in response to being ready to modify the detection period, modify the local CCM detection period, and send a CCM message after the modified CCM detection period, wherein the CCM message is used to enable the opposite device to modify the CCM detection period based on the CCM message.

[0065] Specifically, when the sending end determines that the receiving end is ready to modify the detection period, the sending end further modifies the local CCM detection period. After the modification is completed, the CCM message is sent to the receiving end according to the modified CCM detection period. The receiving end can modify the local CCM detection period according to the CCM message, thereby ensuring the consistency of the operation of the CCM detection period modification at both ends.

[0066] Furthermore, since the sending end does not close the sending function of the CCM message throughout the negotiation process of the modification of the CCM detection period, in order to prevent the receiving end from misprocessing the received CCM message, the sending end makes a corresponding mark in the sent CCM message to identify that the CCM message is a message after the CCM detection period is modified. For example, a bit can be set in the tag field in the CCM message to identify that the period in the CCM message is the modified period, and the bit can be configured according to actual needs.

[0067] In this embodiment, in order to ensure that the receiving end can receive the CCM message after the CCM detection period is modified, the sending end can send several CCM messages after modifying the CCM detection period to ensure that the receiving end can receive the CCM message. During implementation, it is best for the sending end to send 3 CCM messages to the receiving end.

[0068] Furthermore, when the receiving end modifies the local CCM detection period, it sends a CCM message to the sending end. After receiving the CCM message after the CCM detection period is modified, the sending end reports the CCM detection period modification event to the upper system. In addition, since the CCM reception detection is turned off after the CCM detection period modification function is turned on, when the sending end receives the CCM message after the CCM detection period is modified, the CCM reception detection is turned on, that is, the CCM message after the CCM detection period is modified can trigger the turning on of the CCM reception detection of the sending end.

[0069] The following takes the receiving end as an example to describe in detail the method for modifying the CCM detection period in Ethernet OAM disclosed by the present invention. Figure 7 As shown, the modification method includes the following steps:

[0070] S1', receiving a period update notification message, wherein the period update notification message includes an enable field for identifying detection period modification enable information;

[0071] S2', determine whether to enable the time negotiation function;

[0072] Specifically, after the sending end sends the periodic update notification message to the receiving end, the receiving end may receive the periodic update notification message or may not receive the periodic update notification message due to network reasons. The specific processing of the receiving end not receiving the periodic update notification message is described above, and will not be repeated here. Similarly, the specific processing of the periodic update notification message is described above, and will not be repeated here.

[0073] When the receiving end receives the periodic update notification message, it further determines whether to enable the time negotiation function, which is used to identify whether the device needs to modify the CCM detection period. The time negotiation function is enabled in the following ways: one is to enable it through the corresponding command, and the other is to enable it through the corresponding physical button, which can be configured according to actual needs.

[0074] S3', in response to starting the time negotiation function, further determining whether to enable the detection period modification based on the period update notification message;

[0075] Specifically, when the receiving end determines that the time negotiation function is enabled, it further obtains information carried in the period update notification message to determine whether the detection period modification is enabled. During implementation, the receiving end determines whether the detection period needs to be modified through the enable field.

[0076] S4', in response to enabling detection period modification, setting the OAM session to a periodic learning state, turning off CCM reception detection, turning off CCM message sending, and sending a periodic update reply message, wherein the periodic update reply message includes the enable field;

[0077] Specifically, after determining to enable the detection cycle modification, the OAM session is further set to the cycle learning state, and the CCM reception detection is turned off, the CCM sending is turned off, and a cycle update reply message is sent to the sending end. In the cycle update reply message, the second bit of the enable field is set to the first preset value to indicate that it is ready to modify the detection cycle. After receiving the cycle update reply message, the sending end determines whether the receiving end is ready to modify the detection cycle through the enable field in the message.

[0078] S5', receiving the CCM message after the CCM detection period is modified, obtaining the CCM detection period information in the CCM message and updating the local CCM detection period, and enabling the period detection function and the CCM message sending function.

[0079] Specifically, after the receiving end sends a period update reply message to the sending end, it waits to receive a CCM message after the CCM detection period is modified. When the sending end determines through the period update reply message that the receiving end is ready to modify the detection period, it further sends several CCM messages after the CCM detection period is modified to the receiving end.

[0080] When the receiving end receives the first CCM message after the CCM detection period is modified, it further obtains the CCM detection period information carried in the CCM message, and updates the local configuration based on the CCM detection period information to ensure that the local CCM detection period is the same as the CCM detection period in the sending end. At the same time, the period detection function is turned on and CCM sending is turned on. At this time, the receiving period detection and CCM sending period are both the modified period values ​​consistent with the sending end.

[0081] Furthermore, the receiving end needs to report the modification of the CCM detection period to the upper layer system to report the CCM detection period modification event.

[0082] After the receiving end completes the modification of the local CCM detection period, it can send CCM messages to the sending end. After the sending end receives the CCM message, it can trigger the start of the receiving detection.

[0083] The present invention ensures the operational consistency of CCM detection period modification at both ends through the handshake mechanism and linkage processing of periodic update messages (periodic update notification messages and periodic update reply messages) and CCM messages. At the same time, through necessary error shielding configuration (such as closing CCM receiving detection after opening the CCM detection period modification function), it is ensured that some false alarms will not be generated during the modification phase of the CCM detection period, avoiding unnecessary processing and network switching of the upper system.

[0084] like Figure 7As shown, the present invention also discloses a device for modifying the CCM detection period in Ethernet OAM, which is applied to the sending end in Ethernet OAM and can implement the modification method of steps S1 to S3 described above. Specifically, the modification device includes: a first message sending module, a first message receiving module and a first cycle modification module. Among them, the first message sending module is used to send a cycle update notification message after starting the CCM detection period modification, and the cycle update notification message includes an enable field for identifying the detection period modification enable information; the first message receiving module is used to receive a cycle update reply message and determine whether it is ready to modify the detection period, and the cycle update reply message includes the enable field; the first cycle modification module is used to modify the local CCM detection period in response to being ready to modify the detection period, and send a CCM message after modifying the CCM detection period, and the CCM message is used to enable the opposite device to modify the CCM detection period based on the CCM message. This module corresponds one-to-one to the steps of the above method, and will not be repeated here.
