Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to a service resource analysis method. The network management system determines each service model, selects port resources matched with each service model from port resources of the service, and calculates whether available resources exist in each service model, wherein for each service model, if path resources exist in the service model according to the port resources matched with the service model and the routing constraint conditions of the service model, the network management system calculates whether wavelength resources exist in the path resources of the service model according to the optical transmission quality constraint conditions of the service model, and generates service resource information, wherein the service resource information comprises the path resources existing in each service model and the wavelength resources existing in the path resources. The following describes implementation details of the service resource analysis method of this embodiment in detail, and the following is only provided for facilitating understanding of the implementation details and is not necessary for implementing this embodiment.
In this embodiment, there are multiple network elements, each network element is equipped with a board, each board has a port, and each port has multiple wavelength resources or time slot resources of a configurable service.
A specific flow of the service resource analysis method in this embodiment is shown in fig. 1, and includes:
In one example, the network management system may customize multiple service templates by combining different attribute information and/or changing related parameters of the attribute information, and the generated multiple service templates may be stored in a database or a cache for direct extraction when being used again without regeneration. Furthermore, the network management system can sort the service templates generated historically according to the use frequency, so that the service template with the highest use frequency can be found more conveniently when the user selects the service template. The attribute information may include one of the following or any combination thereof: service layer rate, direction of service establishment, customer, activation status, bandwidth, service type, service class, service mode, routing policy, optical damage verification parameter, routing constraint, etc., without limitation.
And 102, selecting the port resource matched with each service model from the port resources of the network.
In one example, the network management system groups each port resource of the network, determines each port resource pair, wherein the port resource pair includes two port resources respectively serving as a departure port and a destination port, and then selects a port resource matched with each service model from each port resource pair according to the service type of each service model. Specifically, a network management system can divide a port in a network into an input port, an output port and a bidirectional port, wherein the input port can be used as a destination port, the output port can be used as a departure port, and the bidirectional port can be used as both the destination port and the departure port; the network management system combines the port capable of being used as the departure port and the port capable of being used as the destination port two by two to be used as a port resource pair, and for the port resource pair consisting of two bidirectional ports, when one of the bidirectional ports is respectively used as the departure port and the destination port, they can form two port resource pairs, for example, bidirectional port A, B, the two port resource pairs are: a as a destination port and B as a departure port, B as a destination port and A as a departure port; of course, the resource pair may also contain port related information, such as: wavelength resources, time slot resources, etc., without limitation herein; further, the service types of the service model may include: an Optical Channel (OCH) type, an Optical Channel Data Unit (ODU) type, a Synchronous Digital Hierarchy (SDH) type, an Optical conversion Unit (OTU) type, and the like, and accordingly, the port types may include an OCH type, an ODU type, an SDH type, an OUT type, and the like, and taking the service type as an OCH type as an example, the network management system may select an OCH type starting port and an OCH type destination port that match the OCH type service model from each port resource pair. In this embodiment, one service model is matched with one port resource pair, that is, one service model is matched with one departure port and one destination port, in practical application, one service model may be matched with a plurality of port resource pairs, and correspondingly, one port resource pair may also be matched with a plurality of service models. It should be noted that, when the practical application is considered, the network resources are very huge, and the network management system can select a part of ports from all the ports to pair to form port resource pairs, thereby reducing the calculation amount.
And 103, obtaining a first calculation result of whether the path resources exist in each service model according to the port resources matched with each service model and the routing constraint conditions of each service model.
In one example, the network management system calculates whether there are resources available for each business model. Specifically, the network management system may determine a priority order of each service model according to attribute information of each service model, where the attribute information may include a service mode, a service level, a service running state, and the like, and taking the service level as an example, the network management system determines the priority order of the service models according to the service level; taking a service mode as an example, the network management system can determine the priority order of the service model according to the historical use frequency of the service mode, and the higher the use frequency is, the higher the; taking the service running state as an example, the better the service running state, the higher the priority of the service model; then, the network management system may obtain, according to the priority order of each service model, a first calculation result of whether each service model has a path resource according to the port resource of each service model and the routing constraint condition of each service model, taking one of the service models as an example, the first calculation result may include that the service model has a path resource, that is, the first calculation result includes a path resource corresponding to the service model, such as: path resources a corresponding to the service model a, for example: port 1, port 2, port 3, and port 4, where port 1 and port 4 are respectively a departure port and a destination port in a port resource pair matched by the service model a. It should be noted that, when the network management system calculates whether the first calculation result of the path resource exists in the service model, a preset rule may be adopted, for example: the shortest path priority rule is taken as an example, the network management system may calculate the path resources existing in the service model according to the shortest path priority rule, and the path resources may include: the shortest path resource, the second shortest path resource, the calculation work protection path resource and the like, wherein the second shortest path resource and the calculation work protection path resource can be used as standby path resources, so that the network management system can complete the establishment of the service under the condition that the shortest path resource is occupied by other services. In this embodiment, the service model a corresponds to the path resource a, that is, one service model corresponds to one path resource, and in practical application, one service model may have a plurality of path resources, which is not limited herein.
In one example, the network management system may group the service models according to attribute information of each service model, such as: the network management system divides the service models into a high-level group, a middle-level group and a low-level group according to the service levels, the service models divided into the high-level group can be calculated preferentially, and the network management system calculates according to the priority sequence of the high-level group, the middle-level group and the low-level group. Further, the priority order of different service models in the same group may not be in sequence.
In one example, the priority order of different business models within the same group may be further determined based on another attribute information. Taking the service mode as an example, the network management system may determine the priority order of each service model in the high-level group according to the historical use frequency of the service mode, and the higher the historical use frequency is, the earlier the priority order of the service model is, so that the service model with the highest historical use frequency of the service mode in the high-level group may be preferentially calculated. That is, the network management system can also determine the priority order of the service models according to the multi-layer attribute information.
It should be noted that, in the above example, the network management system obtains, according to the priority order of each service model, the first calculation result of whether each service model has a path resource according to the port resource of each service model and the routing constraint condition of the service model, and in practical application, the network management system may not be according to the priority order.
In an example, the first calculation result may further include that no path resource exists in the service model, and at this time, the network management system may analyze the reason that no path resource exists in the service model a, for example: the network management system can mark the reason by using the identification code of the service and record the reason, wherein the type of the identification code can be a universal unique identification code, and details are not repeated herein. Preferably, the first calculation result may also be embodied in a correspondence relationship between the service model and the inapplicable path resource, such as: path resource a is not applicable to business model a.
And step 104, if the first calculation result is that the path resource exists, obtaining a second calculation result of whether the wavelength resource exists on the path resource of each service model according to the optical transmission quality constraint condition of each service model.
In an example, if it is calculated that the service model has the path resource, the network management system may obtain a second calculation result of whether the service model has the wavelength resource on the path resource according to the optical transmission quality constraint condition of the service model, where the second calculation result may include that the service model has the wavelength resource on the path resource. Specifically, it is assumed that a path resource a exists on the service model a, then the osnr of optical signals with multiple selectable wavelengths transmitted on the path resource a can be estimated, and according to the osnr and the maximum allowable value of the osnr included in the optical transmission quality constraint condition, it is determined whether a wavelength resource exists on the path resource a in the service model a, and when an optical signal with an osnr smaller than the maximum allowable value of the osnr exists, the network management system can use the wavelength of the existing optical signal as the wavelength resource on the path resource a in the service model a, such as: assuming that there are an optical signal 1 with a wavelength i, an optical signal 2 with a wavelength ii, and an optical signal 3 with a wavelength iii, the osnr of these optical signals transmitted on the path resource a is respectively 30dB, 40dB, and 45dB, and the osnr maximum allowable value is 35dB, since the osnr 30dB corresponding to the optical signal 1 is less than the osnr maximum allowable value 35dB, the network management system can use the wavelength i of the optical signal 1 as the wavelength resource i 'of the service model a on the path resource a, and similarly, the wavelength ii of the optical signal 2 and the wavelength iii of the optical signal 3 cannot be used as the wavelength resource of the service model a on the path resource a, and at this time, the second calculation result is that the service model a has the wavelength resource i' on the path resource a. It should be noted that, in this embodiment, the path resource a corresponds to the wavelength resource i', that is, one path resource corresponds to one wavelength resource, and in practical application, one path resource may correspond to multiple wavelength resources, which is not limited herein.
In one example, the second calculation result may further include that the traffic model does not have a wavelength resource on the path resource. At this time, the network management system may analyze the reason that the service model a does not have the wavelength resource on the path resource a, such as: the optical transmission quality constraint condition is not satisfied, there is no idle wavelength resource, and the like, which is not limited herein. Preferably, the second calculation result may also be specific to a correspondence between the wavelength resource and the inapplicable path resource, such as: wavelength resource i' is not applicable to path resource a.
And 105, generating service resource information according to the first calculation result and the second calculation result.
In one example, the service resource information includes path resources existing in each service model and wavelength resources existing on the path resources. For example, for the business model a, path resources a, b, c exist as a first calculation result; for the path resource a of the service model A, the second calculation result is that a wavelength resource I' exists; for the path resource b of the service model A, the second calculation result is that a wavelength resource II' exists; for the path resource c of the service model a, the second calculation result is that the wavelength resource iii' exists, then, the service resource information generated by the network management system includes resource information corresponding to each service model, that is: the service model A has a wavelength resource I ' on the path resource a, a wavelength resource II ' on the path resource b and a wavelength resource III ' on the path resource c. The resource information corresponding to each service model may exist in the form of records, and each record may be understood as a corresponding relationship between a service model, a path resource, and a wavelength resource.
In an example, assuming that the first calculation result is that a path resource exists in the service model a, and the path resource includes path resources a and b, and for the path resource a of the service model a, the second calculation result is that no wavelength resource exists, and for the path resource b of the service model a, the second calculation result is that no wavelength resource exists, then, the service resource information generated by the network management system may include: the service model a does not have a wavelength resource on the path resource a, and the service model a does not have a wavelength resource on the path resource b, at this time, taking the example that the service model a does not have a wavelength resource on the path resource a, the network management system may analyze a specific reason, which has been exemplified in the above contents, and is not described herein again.
In one example, the network management system may store the calculation result of the history, or may store the calculation result by means of other devices, such as: and sending the calculation result to a Software Defined Network (SDN) controller, and storing the SDN controller, wherein the Network management system does not need to store the historical calculation result and can extract the calculation result from the SDN controller when needed. The embodiment can reduce the storage pressure of the network management system and enhance the computing capacity of the network management system. The method for sending the calculation result may be: the network management system uses the hk2 lightweight dynamic architecture technology to realize the message conversion between the Yaml interface and the Yang interface of the micro-service processing, namely, the calculation result is converted into the Yang interface message, so that the calculation result is sent to the SDN controller through the Yaml interface of the network management system.
In this embodiment, the network management system determines each service model, selects a port resource matched with each service model from each port resource of the network, and calculates whether each service model has a path resource or not, and further calculates whether each service model has a wavelength resource or not on the path resource, so as to obtain service resource information before establishing a service, accurately judge whether the current service resource is available, and avoid finding that the service resource is occupied after a service is failed to be established.
A second embodiment of the present invention relates to a service resource analysis method. The second embodiment is substantially the same as the first embodiment, with the main differences being: in the second embodiment of the present invention, after the network management system generates the service resource information according to the first calculation result and the second calculation result, when receiving the service resource change message, the network management system obtains the first calculation result of whether the path resource exists in each service model according to the port resource matched with each service model and the routing constraint condition of each service model again. The following describes implementation details of the service resource analysis method of this embodiment in detail, and the following is only provided for facilitating understanding of the implementation details and is not necessary for implementing this embodiment.

Wherein the service resource change message comprises at least one of the following messages: creating message of occupying resources by service, deleting message of releasing resources by service, and modifying message of changing resources by service.
In one example, when receiving the service resource change message, the network management system obtains the first calculation result of whether the path resource exists in each service model according to the port resource matched with each service model and the routing constraint condition of each service model again. Assuming that the SDN controller receives the message for creating the service occupation resource, the SDN controller may send the message to the network management system, and then the network management system starts to execute steps 203 to 206.
It should be noted that, when the network management system receives the service resource change message and executes step 205 again, the originally generated service resource information may be updated according to the first calculation result and the second calculation result, that is, the service resource information that has not been changed is retained. The embodiment can reduce the data change amount and the workload of the network management system.
In this embodiment, the network management system may re-execute the calculation action according to the resource change condition to dynamically update the service resource information, so that the service resource information more accurately reflects the current service resource state.

The steps 301, 302, 303, 304, and 305 are similar to the steps 101, 102, 103, 104, and 105, respectively, and are not described herein again.
And step 306, visually displaying the service resource information.
