According to the scheme, after the manufacturer equipment controller receives the routing resource request of the operator controller, whether the routing resource to be requested corresponding to the routing resource request is locked is judged; when the routing resource to be requested is locked, acquiring an information summary algorithm MD5 value corresponding to the routing resource request, acquiring a resource list corresponding to an MD5 value, and feeding the resource list back to the operator controller; when the routing resource to be requested is not locked, a current transaction corresponding to the routing resource to be requested is started, the transmission line resource corresponding to the routing resource to be requested is applied in the current transaction, the validity of the resource applied by the operator controller can be ensured, the application and the use of the circuit resource by the operator controller are in different processes, the separation of resource things and use is realized, the utilization rate of the routing resource is improved, the manufacturer equipment controller avoids that a large amount of network resources are idle due to the fact that the operator controller applies the resource for multiple times, and the resource inquired by the operator controller is ensured to be an available resource.

Based on the hardware structure, the embodiment of the resource scheduling method is provided.

Referring to fig. 2, fig. 2 is a flowchart illustrating a resource scheduling method according to a first embodiment of the present invention.

In a first embodiment, the resource scheduling method includes the following steps:

step S10, after the manufacturer device controller receives the route resource request from the operator controller, it determines whether the route resource to be requested corresponding to the route resource request is locked.

It should be noted that the routing resource is a request for applying for use of a resource corresponding to a relevant route, and after receiving a routing resource request from an operator controller, a manufacturer device controller determines whether a to-be-requested routing resource corresponding to the routing resource request is locked, and determines whether the to-be-requested routing resource has been requested but is not occupied by an actual circuit; the route resource request may be a cross-domain route request or an intra-domain route request, which is not limited in this embodiment.

Step S20, when the routing resource to be requested is locked, obtaining an information digest algorithm MD5 value corresponding to the routing resource request, obtaining a resource list corresponding to the MD5 value, and feeding back the resource list to the operator controller.

It should be understood that different routing resource requests may correspond to different values of the information summarization algorithm MD5, when the routing resource to be requested is locked, a resource list corresponding to the value of MD5 can be obtained, where the resource list is the detailed information of the locked resource corresponding to the value of MD5, and after the resource list is obtained, the detailed information of the locked resource can be directly fed back to the operator controller, so that the operator controller can quickly obtain the relevant resource corresponding to the resource list.

Step S30, when the routing resource to be requested is not locked, starting a current transaction corresponding to the routing resource to be requested, and applying for a transmission line resource corresponding to the routing resource to be requested in the current transaction.

It can be understood that the transmission line resource is an available transmission line resource corresponding to the routing resource to be requested, that is, an available circuit resource, when the routing resource to be requested is not locked, the manufacturer device controller may start a new transaction, that is, start the current transaction corresponding to the routing resource to be requested, and may apply for the circuit resource in the new transaction after starting the current transaction, that is, apply for the transmission line resource corresponding to the routing resource to be requested in the current transaction, thereby ensuring that the resource queried by the operator controller is the available resource.

Further, fig. 3 is a flowchart illustrating a second embodiment of the resource scheduling method of the present invention, and as shown in fig. 3, the second embodiment of the resource scheduling method of the present invention is proposed based on the first embodiment, and in this embodiment, the step S10 specifically includes the following steps:

step S11, after receiving the route resource request from the operator controller, the manufacturer device controller obtains a request feature parameter set corresponding to the route resource request, where the request feature parameter set is a unique feature parameter set describing the route resource request.

It should be noted that, the request feature parameter set is a unique feature parameter set describing the routing resource request, and the request feature parameter set generally includes: source and destination ports, transmission line rates, routing constraints, i.e., resources that must be passed through and bypassed by the route, etc.; of course, the request feature parameter set may also include more or less parameters, which is not limited in this embodiment; of course, the request feature parameter sets corresponding to different routing resource requests are different, and the routing resource request needs to be analyzed to obtain the required feature parameters.

And step S12, obtaining the request MD5 value corresponding to the request feature parameter set.

It is understood that after obtaining the request feature parameter set, a message digest operation may be performed according to each feature parameter in the request feature parameter set, and a corresponding value of request MD5 is obtained through calculation.

And step S13, inquiring whether the request MD5 value exists in a preset first cache, and generating an inquiry result.

It should be understood that the preset first cache is a cache in the vendor device controller, and stored in the first cache is a key value pair consisting of a request MD5 value corresponding to a request feature parameter set and an ID of a transaction opened when applying for a routing resource, for example, (MD5-1, fransid), MD5-1 is a request MD5 value corresponding to the request feature parameter set, and fransid is an ID of a transaction opened when applying for a resource; by performing query operation in the preset first cache, it can be determined whether the request MD5 value corresponding to the request feature parameter set exists in the preset first cache.

And step S14, when the query result is that the request MD5 value exists, determining that the route resource to be requested corresponding to the route resource request is locked.

It can be understood that, when the query result is that the request MD5 value exists in the preset first cache, it may be determined that the to-be-requested routing resource corresponding to the routing resource request is locked, that is, the to-be-requested routing resource has been requested but is not occupied by an actual circuit.

And step S15, when the query result is that the request MD5 value does not exist, determining that the route resource to be requested corresponding to the route resource request is not locked.

It should be understood that, correspondingly, when the query result is that the request MD5 value does not exist in the preset first cache, it may be determined that the to-be-requested routing resource corresponding to the routing resource request is not locked, that is, the to-be-requested routing resource is not requested.

In this embodiment, with the above scheme, after receiving a routing resource request from an operator controller through a manufacturer device controller, a request feature parameter set corresponding to the routing resource request is obtained, where the request feature parameter set is a unique feature parameter set describing the routing resource request; acquiring a request MD5 value corresponding to the request feature parameter set; inquiring whether the request MD5 value exists in a preset first cache, and generating an inquiry result; when the query result is that the request MD5 value exists, determining that the to-be-requested routing resource corresponding to the routing resource request is locked; when the query result is that the request MD5 value does not exist, it is determined that the to-be-requested routing resource corresponding to the routing resource request is not locked, and it can be ensured that the resource queried by the operator controller is an available resource; the effectiveness of the operator controller applying for the resources can be ensured, the resources are prevented from being locked in large quantities due to repeated inquiry of the available routes, and the utilization rate of the route resources is improved.

Further, fig. 4 is a flowchart illustrating a resource scheduling method according to a third embodiment of the present invention, and as shown in fig. 4, the third embodiment of the resource scheduling method according to the present invention is proposed based on the first embodiment, in this embodiment, the step S20 specifically includes the following steps:

step S21, when the route resource to be requested is locked, obtaining a request feature parameter set corresponding to the route resource request, and obtaining a request MD5 value corresponding to the route resource request from the request feature parameter set.

It should be noted that, when the route resource to be requested is locked, the manufacturer device controller may obtain the request feature parameter set corresponding to the route resource request, and further obtain the request MD5 value corresponding to the route resource request from the request feature parameter set, that is, calculate the request MD5 value corresponding to the route resource request through a message digest algorithm.

Step S22, obtaining the unique code of the request transaction corresponding to the request MD5 value from the preset first cache.

It can be understood that the preset first cache stores a request MD5 value and an ID of a request transaction opened when applying for a resource, that is, a key value pair consisting of a unique code of a request transaction, and a request transaction ID when applying for a resource, that is, a unique code of a request transaction, corresponding to the request MD5 value can be obtained from the preset first cache through a query operation.

Step S23, obtaining resource detail information corresponding to the unique code of the request transaction from a preset second cache, and generating a resource list according to the resource detail information.

It should be noted that the preset first cache stores an MD5 value corresponding to the request feature parameter set and an ID of a transaction opened when applying for a routing resource; the preset second cache stores MD5 values corresponding to the routing resources, transaction IDs started when the routing resources are applied, and resource detailed information corresponding to each routing resource, and the resource detailed information corresponding to the MD5 value can be generally queried through the MD5 value corresponding to the routing resources.

It should be understood that the preset second cache is another cache in the vendor device controller, and is used for storing a key value pair consisting of a resource MD5 value corresponding to a routing resource and a transaction ID opened when applying for the routing resource, such as (MD5-2, fransid), where MD5-2 is an MD5 value corresponding to the routing resource and the fransid is a request transaction ID opened when applying for the routing resource; after the resource detailed information corresponding to the unique code of the request transaction is obtained from the preset second cache, a corresponding resource list can be generated according to the resource detailed information.

And step S24, feeding back the resource list to the operator controller.

It can be understood that after the resource list is obtained, the resource list is fed back to the operator controller, and through a timely and efficient feedback process, the speed and efficiency of the operator controller for calling related resources can be increased, the validity of the operator controller for applying for the resources can be ensured, the resources are prevented from being locked in a large amount due to repeated inquiry of available routes, and the utilization rate of the routing resources is improved.

In this embodiment, with the above scheme, when the route resource to be requested is locked, a request feature parameter set corresponding to the route resource request is obtained, and a request MD5 value corresponding to the route resource request is obtained from the request feature parameter set; obtaining a request transaction unique code corresponding to the request MD5 value from the preset first cache; acquiring resource detailed information corresponding to the unique code of the request transaction in a preset second cache, and generating a resource list according to the resource detailed information; feeding back the resource inventory to the operator controller; the speed and the efficiency of calling related resources by the operator controller can be increased, the effectiveness of applying for the resources by the operator controller can be ensured, the resources are prevented from being locked in large quantities due to repeated inquiry of available routes, and the utilization rate of the route resources is improved.

Further, fig. 5 is a flowchart illustrating a fourth embodiment of the resource scheduling method of the present invention, and as shown in fig. 5, the fourth embodiment of the resource scheduling method of the present invention is proposed based on the first embodiment, and in this embodiment, after step S30, the resource scheduling method further includes the following steps:

and step S40, after the transmission line resource is successfully applied, acquiring the current transaction unique code of the current transaction, and storing the request MD5 value and the current transaction unique code into a preset first cache.

It should be noted that, after applying for a successful transmission line resource, the vendor device controller may store the MD5 value corresponding to the request feature parameter set and the transaction ID of the current transaction, that is, the unique code of the current transaction, in the preset first buffer.

And step S50, acquiring a resource MD5 value corresponding to the resource data of the transmission line resource, and storing the resource MD5 value and the current transaction unique code in a preset second buffer.

It should be understood that the manufacturer device controller may apply for the resource MD5 value corresponding to the resource data, that is, the resource MD5 value corresponding to the resource data of the transmission line resource and the transaction ID of the open transaction, and store the current transaction unique code in the preset second buffer.

In this embodiment, by using the above scheme, after a transmission line resource is successfully applied, the unique current transaction code of the current transaction is obtained, and the MD5 value and the unique current transaction code are stored in the preset first cache; and acquiring a resource MD5 value corresponding to the resource data of the transmission line resource, and storing the resource MD5 value and the current transaction unique code in the preset second cache, so that the effectiveness of applying for the resource by the operator controller can be ensured, the application and the use of the operator controller for the circuit resource are in different processes, the separation of the things and the use of the resource is realized, and the utilization rate of the routing resource is improved.

Further, fig. 6 is a flowchart illustrating a fifth embodiment of the resource scheduling method of the present invention, and as shown in fig. 6, the fifth embodiment of the resource scheduling method of the present invention is proposed based on the fourth embodiment, in this embodiment, after step S50, the method for improving microservice further includes the following steps:

step S60, after receiving the route creation request from the operator controller, determining whether the to-be-issued routing resource corresponding to the route creation request is locked, and generating a determination result.

It should be noted that the line creation request is a request for creating a new line again, and the to-be-issued routing resource is a routing resource that needs to be called and corresponds to the line creation request; after receiving a line creation request of an operator controller, judging whether a to-be-issued routing resource corresponding to the line creation request is locked or not, so that the situations that the same resource is inquired, a calling error is caused, and network resources of a manufacturer equipment controller are greatly idle can be effectively avoided.

And step S70, according to the judgment result, performing circuit creation on the prefabricated circuit corresponding to the to-be-issued routing resource, or reapplying for transmission line resources.

It can be understood that the pre-established line is a pre-set line to be created corresponding to the route resource to be issued, that is, a line matched with the route resource to be issued, and it can be determined to create a pre-established line or reapply for a transmission line resource according to the determination result, depending on whether the route resource to be issued corresponding to the line creation request in the determination result is locked.

According to the scheme, after receiving the line creation request of the operator controller, the embodiment judges whether the to-be-issued routing resource corresponding to the line creation request is locked or not, and generates a judgment result; and performing line creation on the prefabricated line corresponding to the to-be-issued routing resource according to the judgment result, or reapplying for the transmission line resource, so that the flexibility of the manufacturer equipment controller for utilizing the routing resource can be improved, and the effectiveness of the resource applied by the operator controller is ensured.

It should be noted that, when the resource MD5 value matching the line MD5 value exists in the preset second cache, it may be determined that the to-be-issued routing resource corresponding to the line creation request is locked, and otherwise, the to-be-issued routing resource is not locked.

According to the scheme, after a line creation request of an operator controller is received, a line feature parameter set corresponding to the line creation request is obtained, wherein the line feature parameter set is a unique feature parameter set describing routing resources corresponding to the line creation request; acquiring a line MD5 value corresponding to the line characteristic parameter set; searching whether a resource MD5 value matched with the line MD5 value exists in the preset second cache, and generating a search result; judging whether the to-be-issued routing resource corresponding to the line creation request is locked or not according to the search result, and generating a judgment result; the method can ensure the accuracy of circuit creation, avoid the situation that the same resource is repeatedly created, ensure the effectiveness of the resource applied by the operator controller, and ensure that the resource inquired by the operator controller is the available resource.

Further, fig. 8 is a flowchart illustrating a seventh embodiment of the resource scheduling method of the present invention, and as shown in fig. 8, the seventh embodiment of the resource scheduling method of the present invention is proposed based on the fifth embodiment, in this embodiment, the step S70 specifically includes the following steps:

step S71, obtaining the unique line transaction code corresponding to the MD5 value from the preset second buffer.

It should be noted that the preset second cache stores a key value pair consisting of an MD5 value and a corresponding transaction ID, and the preset second cache can obtain a resource MD5 value matching the line MD5 value, and further determine the corresponding transaction ID, that is, the unique line transaction code, according to the resource MD5 value.

Step S72, when the determination result indicates that the routing resource to be issued is locked, submitting the line transaction corresponding to the unique line transaction code, completing creating a pre-manufactured line corresponding to the routing resource to be issued, and removing the cache data corresponding to the unique line transaction code from the preset first cache and the preset second cache.

It can be understood that, when the to-be-issued routing resource is locked, the manufacturer device controller may determine a corresponding line transaction through the line transaction unique code and submit the transaction, thereby completing creation of a pre-fabricated line and instantiating the pre-fabricated line, and at the same time, may remove an entry corresponding to the line transaction unique code and a corresponding cache from the pre-fabricated first cache and the pre-fabricated second cache.

And step S73, when the judgment result is that the to-be-issued routing resource is not locked, starting a line transaction corresponding to the to-be-issued routing resource, and applying for transmission line resources in the line transaction.

It should be understood that, when the to-be-issued routing resource is not locked, the manufacturer device controller may start a new transaction, that is, start a line transaction corresponding to the to-be-issued routing resource, apply for transmission of the line resource in the line transaction, and determine again whether the routing resource corresponding to the new transaction is locked.

In this embodiment, by using the above scheme, the unique line transaction code corresponding to the line MD5 value is obtained from the preset second buffer; when the judgment result is that the routing resource to be issued is locked, submitting the line transaction corresponding to the unique code of the line transaction, completing the creation of the prefabricated line corresponding to the routing resource to be issued, and removing the cache data corresponding to the unique code of the line transaction from the preset first cache and the preset second cache; when the judgment result is that the to-be-issued routing resource is not locked, the line transaction corresponding to the to-be-issued routing resource is started, the transmission line resource is applied in the line transaction, the accuracy of circuit creation can be ensured, the situation that the same resource is repeatedly created is avoided, the effectiveness of applying the resource by the operator controller can be ensured, the resource inquired by the operator controller is ensured to be an available resource, the application and the use of the circuit resource by the operator controller are in different processes, the separation of the things and the use of the resource is realized, and the utilization rate of the routing resource is improved.

Further, fig. 9 is a flowchart illustrating an eighth embodiment of the resource scheduling method of the present invention, and as shown in fig. 9, the eighth embodiment of the resource scheduling method of the present invention is proposed based on the first embodiment, and in this embodiment, after step S10, the resource scheduling method further includes the following steps:

and step S101, acquiring the locking accumulated time of the locked target to-be-requested routing resource.

It should be noted that the lock accumulated time is the accumulated time from the locking start of the target to-be-requested routing resource until the target to-be-requested routing resource is queried again, for example, if the resource is locked at a certain time, the lock accumulated time t starts to be counted; if the locked resource is queried again at a certain time, the locking accumulated time t is counted again.

Step S102, comparing the locking accumulated time with a preset time threshold, releasing the target to-be-requested routing resource when the locking accumulated time is greater than the preset time threshold, and removing transaction data corresponding to the target to-be-requested routing resource in a preset cache.

It can be understood that the preset time threshold is a preset time threshold for comparing with the lock accumulation time, the lock accumulation time is compared with the preset time threshold, when the lock accumulation time is greater than the preset time threshold, the target to-be-requested routing resource is released, a transaction applying for the target to-be-requested routing resource is cancelled, a corresponding resource is released, and a corresponding related entry is removed from a preset cache, that is, the transaction data corresponding to the target to-be-requested routing resource is removed.

According to the scheme, the locking accumulated time of the locked target to-be-requested routing resource is obtained; and comparing the locking accumulated time with a preset time threshold, releasing the target to-be-requested routing resource when the locking accumulated time is greater than the preset time threshold, and removing the transaction data corresponding to the target to-be-requested routing resource from a preset cache, so that the effectiveness and recoverability of the resource applied by the operator controller can be ensured, the resource is prevented from being locked in large quantity, and the utilization rate and the recovery rate of the routing resource are improved.

Step S0022, decomposing the service to be cross-domain into line establishing requests in the routing boundary points of each domain according to the cross-domain service opening instruction, and sending the line establishing requests to equipment controllers of various manufacturers.

It should be understood that, according to the cross-domain service provisioning instruction, the operator controller may initiate a cross-domain routing request, decompose the cross-domain request into resource requests in the routing boundary points of each domain, and issue the resource requests to each manufacturer equipment controller, that is, decompose the to-be-cross-domain service into line creation requests in the routing boundary points of each domain, and issue the line creation requests to each manufacturer equipment controller.
