Description

Business processing method and device

Technical field

The present disclosure relates to the field of communications, for example, to a service processing method and apparatus.

Background technique

Network survivability refers to the ability to maintain an acceptable level of service quality when a network device fails. At this stage, the optical network has higher and higher requirements for survivability. Recovery of Automatic Protection Switching (APS) and Automatically Switched Optical Network (ASON) is the main method to improve network survivability.

The ASON recovery operation does not pre-allocate the working channel or the protection channel for the service. When the working channel or the protection channel fails, the recovery control unit calculates a new channel in real time from the idle available resources of the current network, and in the path. The other recovery control units perform the signaling interaction. Finally, all the recovery control units in the new channel deliver the handover command to the device that actually carries the service, and switch to the new channel. The advantage of recovery is that the bandwidth utilization is high, and the disadvantage is the interruption time. A little longer.

The APS automatic protection switching operation pre-allocates the working channel and the protection channel. When the working channel or the protection channel fails, the protection control unit executes the protocol algorithm in the standard, and the protection control unit of the first and last nodes also performs signaling interaction. The first and last nodes finally send a switching command to the device that actually carries the service, and switch to the working channel or the protection channel. The advantage of protection is high stability, short interruption time, and the disadvantage is low bandwidth utilization.

For a network with automatic switched optical network ASON deployment, the service is often configured with protection and recovery functions. When the working or protection channel fails, the automatic protection switching is performed first, and the service traffic is switched to the protection or working channel. If a new work or protection channel is restored, if the automatic protection switch fails, the recovery operation will be performed first, and the service traffic will be switched to the new channel. Therefore, protection and recovery need to work together.

Normally, the recovery will be performed after the protection. After the work or protection channel has an alarm, the recovery control unit will start a timer. After the timer expires, check whether the channel has an alarm. If there is an alarm, the recovery operation will be started. Switching traffic, so that the recovery operation is not timely, let the protection control unit notify the recovery control unit to immediately start the recovery operation switching traffic within the timer range of the timer, On how it will increase the business interruption time. If the recovery is very timely, the recovery control unit does not start the timer and ignores the result of the protection switching, but the recovery control unit cannot work well with the protection control unit. For example, the protection switching may succeed or fail. Successfully, the recovery control unit only needs to restore the new channel path without switching the traffic. If it fails, the recovery control unit needs to restore the new channel path and switch the traffic at the same time. In addition, the protection protocol has its own set of algorithms. Traffic switching does not take into account the requirements of ASON. In some special scenarios, ASON prefers that APS does not switch traffic, but initiates ASON recovery operations.

Related technologies include how to coordinate protection and recovery methods, such as adding message interactions in the protection control unit and the recovery control unit to coordinate, which will increase the interruption time of the service, and in some special scenarios, in order to satisfy the ASON Restoring demand requires APS special handling and destroys the standard protocol of its own APS.

In view of the related art, the existing service interruption time caused by the coordination scheme of the APS protection and the ASON recovery has not been put forward, and an effective solution has not been proposed.

FIG. 4 is a schematic structural diagram of a service processing apparatus according to an embodiment of the present disclosure, and FIG. 5 is a flowchart of a service processing method according to an embodiment of the present disclosure.

Example 1

The first embodiment provides a service processing device. As shown in FIG. 5, the device includes a service lifting and lowering control unit 50, a channel alarm detecting unit 52, a protection control unit 54, and a recovery control unit 56.

The present embodiment further provides a service processing method, and FIG. 4 is a flowchart of a service processing method according to an embodiment of the present disclosure. As shown in FIG. 4, the steps of the method include:

Step S202: When an alarm is generated, check the alarm type. When the alarm type is a protection channel alarm, Step S204 is performed, when the alarm type is a working channel alarm, step S206 is performed;

Step S204: Keep the service level unchanged;

Step S206: determining whether the channel recovery is successful; when the determination result is yes, step S208 is performed, and if the determination result is no, step S210 is performed;

Step S208: the service level is unchanged;

Step S210: Degrading the service, removing the protection attribute, and retaining only the recovery attribute;

Step S212: When the working channel alarm disappears and the recovery is successful, the service is upgraded, and the protection attribute is added.

It can be seen from the above steps S202 to S212 that the channel alarm detecting unit detects the fault of the service and the protection channel, reports the alarm message to the lifting level control unit when the working channel fails, and simultaneously restores the control unit to report the recovery failure message to The lifting level control unit performs the degradation of the service, removes the protection attribute, and only retains the recovery attribute. After the channel alarm detecting unit detects that the working channel alarm disappears, and at the same time, the recovery control unit reports the recovery success message to the lifting level control unit to perform the service. Upgrade to increase protection attributes.

To explain the present embodiment, the method of this embodiment will be described in detail below. The steps of the method are as follows:

Step S302: When the channel alarm detecting unit of the device detects the working fault, it reports to the lifting level control unit and at the same time restores the control unit to report the recovery failure message to the lifting stage control unit, and the lifting stage control unit performs the derating operation.

The step S302 includes:

Step S302-1: After receiving the work fault alarm reported by the channel alarm detecting unit, the lifting level control unit waits for the recovery control unit to report the success or failure of the recovery. At this time, when the recovery control unit starts the recovery operation, if the current calculation is performed, If no idle path is available, the failure will be restored, and the recovery failure message will be reported to the lifting and lowering control unit. If the available idle path can be calculated, the recovery will be successful, and the recovery success message will be reported to the lifting and lowering control unit, so that the degraded operation will not be performed. .

Step S302-2: If the degrading operation is performed, the elevating stage control unit notifies the recovery control unit and the protection control unit to degrade the message, and temporarily removes the protection attribute of the service. After receiving the degraded message, the protection control unit temporarily does not process the alarm or the protection channel alarm of the service reported by the channel alarm detection unit, and the channel alarm of the service reported by the channel alarm detection unit after the recovery control unit receives the degraded message. Perform recovery directly.

Step S304: The channel alarm detecting unit of the device detects that the working fault has disappeared and reports it to the lifting level control unit and the recovery control unit reports the recovery success message to the lifting level control unit, and the lifting level control unit performs an upgrading operation.

Wherein, step S304 includes:

Step S304-1: After receiving the work failure alarm reported by the channel alarm detection unit, the lifting level control unit waits for the recovery control unit to report the success or failure of the recovery. At this time, when the recovery control unit starts the recovery operation, the calculation is available. The idle path will be successfully restored, and the recovery success message will be reported to the elevator control unit.

Step S304-2: If the upgrade operation is performed, the elevation level control unit notifies the restoration control unit and the protection control unit to upgrade the message, and increases the protection attribute of the service. After receiving the upgrade message, the protection control unit and the recovery control unit process the alarm or the protection channel alarm reported by the channel alarm detection unit according to step 6.

Step S306: The channel alarm detecting unit, the lifting level control unit, the protection control unit, and the recovery control unit have the following message interactions, which are described in conjunction with FIG. 5. FIG. 5 is a schematic structural diagram of a service processing apparatus according to an embodiment of the present disclosure.

Step S306-1: After detecting the working or protection channel alarm, the channel alarm detecting unit sends an alarm detection message 401 to the lifting and lowering control unit, the protection control unit, and the recovery control unit, wherein the alarm detection message includes the alarm board address and port. Whether the alarm is generated or disappeared.

Step S306-2: The recovery control unit notifies the resume level control unit of the recovery success or failure message 402.

Step S306-3: The elevation level control unit notifies the protection control unit and the restoration control unit to the downgrade or upgrade message 403 at the same time.

Step S306-4: The protection control unit notifies the recovery control unit of the switching success or failure message 404.

Step S308: when the channel alarm detecting unit of the above device detects the protection fault, it is also reported to the lifting level control unit, and the lifting level control unit does not perform the lifting level processing.

Step S310: The above-mentioned channel alarm detecting unit, the lifting level control unit, the protection control unit, and the recovery control unit have a reliable communication mechanism, which can be implemented by process or inter-thread communication, and advanced data links such as TCP/IP.

Step S312: The channel alarm detecting unit of the above device simultaneously transmits the working or protection channel alarm to the protection control unit and the recovery control unit.

Wherein, step S312 includes:

Step S312-1: After receiving the alarm, the protection control unit triggers the protection protocol calculation, performs automatic protection switching, and switches the traffic to the new channel path.

Step S312-2: After the recovery control unit receives the alarm, a timer is started.

Step S312-3: In the range of the timer timing, the switching success message sent by the protection control unit is received, and the timer is cleared, and the new working or protection channel path is immediately restored.

Step S312-4: Within the range of the timer timing, the switching failure message sent by the protection control unit is received, and the recovery operation is immediately started. If the recovery is successful, the traffic is switched to the new channel path.

Step S312-5: After the timer expires, the recovery control unit checks whether there is an alarm in the working or protection channel. If there is an alarm, the recovery operation is immediately started. If the recovery is successful, the traffic is switched to the new channel path.

In Embodiment 2, a service with a high priority (for example, may be a diamond-level service) is downgraded and then upgraded:

FIG. 6 is a network topology diagram according to an embodiment of the present disclosure. As shown in FIG. 6 , ASON establishes a diamond level 1+1 service AE, and three available paths are ABE, ACE, ADE, and the initial working path selects ABE. The initial protection path selects the ACE, and the working and protection paths respectively have recovery attributes, and an alarm exists on the path ADE.

An alarm is detected on the initial working path ABE at a certain moment. The alarm is detected by the channel alarm detecting unit and reported to the lifting level control unit, the protection control unit, and the recovery control unit. The lifting level control unit waits for the recovery control unit after receiving the working alarm. If the reported recovery is successful, the recovery control unit starts the timer to wait for the protection control unit to report the success of the switching, and the protection control unit executes the APS protocol algorithm after receiving the working alarm to obtain the current protection group status as the SF channel failure, the request signal. If the bridge signal is 1, the traffic is switched to the protection channel ACE, and the recovery control unit reports the success message to the recovery control unit. The recovery control unit calculates other currently available paths. Since there are alarms on the path ADE, there are currently no idle resources. If the recovery fails, the recovery failure message is reported to the elevator control unit. At this time, the service is degraded, and the protection attribute is temporarily removed, leaving only the recovery attribute of the path ACE.

At some time after a period of time, the alarm passing through the ADE disappears, the channel alarm detection unit reports to the lifting level control unit, the protection control unit, and the recovery control unit, wherein the recovery control unit attempts to restore the new working path ADE, after the recovery is successful. Notify the lifting level control unit, perform the upgrade operation, increase the protection attribute of the service, update the new working path ADE, and the original protection path is still ACE. At this time, the traffic is still protecting the path through the ACE, and the service is downgraded to the upgrade process. carry out.

If the alarm of the protection path is detected first at the beginning, the service will not be degraded and the traffic will remain on the A-B-E.

If the work path is successfully detected after the initial detection of the work path alarm, the downgrade will not be performed, but the working path of the service protection group is updated by A-D-E.

7 is a flowchart of an upgrade according to Embodiment 2 of the present disclosure. As shown in FIG. 7, the upgrade process of the entire diamond level 1+1 service includes:

Step S702: The service traffic is in the working channel;

Step S704: Check the alarm type, wherein, when the alarm type is the working channel alarm, step S706 is performed, and when the alarm type is the protection channel alarm, step S716 is performed;

Step S706: automatic protection switching, and the traffic is switched to the protection channel;

Step S708: determining whether the working channel is successfully restored, when the determination result is yes, step S710 is performed, and if the determination result is no, step S712 is performed;

Step S710: The service updates the working channel path, and the level is unchanged;

Step S712: The service is demoted to only the recovery attribute;

Step S714: The service updates the working channel path and upgrades to the diamond-level service.

Step S716: determining whether the protection channel recovery is successful, when the determination result is yes, step S718 is performed, and if the determination result is no, step S720 is performed;

Step S718: The service update protects the path of the channel, and the level is unchanged;

Step S720: The service level is unchanged.

In case 3, the higher-level business (for example, the gold-level business) is upgraded after downgrading:

As shown in Figure 6, ASON establishes a gold-level 1+1 service A-E. There are three available paths, namely A-B-E, A-C-E, and A-D-E. The initial working path is A-B-E, the initial protection path is A-C-E, and the protection path has recovery attributes.

An alarm is detected on the initial working path ABE at a certain moment. The alarm is detected by the channel alarm detection unit and reported to the lifting level control unit, the protection control unit, and the recovery control unit. The protection control unit executes the APS protocol algorithm after receiving the working alarm. The current protection group status is SF channel failure, the request signal is 1, the bridge signal is 1, the traffic is switched to the protection channel ACE, and the lifting level control unit directly performs the degrading operation after receiving the work alarm, which is different from the diamond level service. The job of the level service is that there is no recovery attribute, and the protection attribute is temporarily removed, leaving only the recovery attribute of the path ACE.

At some time after a certain period of time, the alarm of the original working path through the ABE disappears, and the channel alarm detecting unit reports to the lifting level control unit, the protection control unit, and the recovery control unit, wherein the lifting level control unit directly performs the upgrading operation to increase the service. The protection attribute is still the original working path ABE. The original protection path is still ACE. At this time, the traffic is still protecting the path through the ACE, and the process from the downgrade to the upgrade is completed.

FIG. 8 is a flowchart of an upgrade according to Embodiment 3 of the present disclosure, and the process of upgrading the entire gold-level service shown in FIG. 8 includes:

Step S802: The service traffic is in the working channel;

Step S804: Check the alarm type, when the alarm type is the working channel alarm, step S806 is performed, and when the alarm type is the protection channel alarm, step S812 is performed;

Step S806: automatic protection switching, and the traffic is switched to the protection channel;

Step S808: The service is demoted to only the recovery attribute;

Step S810: When the working channel is successfully restored, the gold return service is upgraded;

Step S812: determining whether the protection channel recovery is successful, when the determination result is yes, step S814 is performed, and if the determination result is no, step S816 is performed;

Step S814: The service update protects the path of the channel, and the level is unchanged;

Step S816: The service level is unchanged.

In case 4, the recovery operation of ASON replaces the traffic switching of APS:

An alarm is detected on the initial working path A-B-E at a certain moment, or is degraded according to Embodiment 3. In the process, if the protection path detects the alarm again through the A-C-E, the recovery control unit directly restores the protection path according to the method of the present disclosure, calculates the current available path A-D-E of the network, and directly switches the service traffic to the A-D-E.

If the protection attribute does not exist according to the degradation scheme in the method of the present disclosure, according to the APS protocol algorithm, the priority of the protection channel failure is higher than the priority of the work channel failure, and the protection control unit switches the traffic to the original working path ABE. On the other hand, the ABE alarm still exists, so that the recovery operation cannot be performed, and the service is always interrupted, causing considerable loss.
