303. And the first platform receives the identifier of the first access layer equipment sent by the opening device of the private line service.
304. And the first platform sends the identifier of the first core layer equipment to the opening device of the private line service.
After receiving the identifier of the first access layer device, the first platform may select, according to a pre-stored nearby routing principle, a convergence layer device that is close to the first access layer device in a transport network managed by the first platform, and then select a corresponding first core layer device, to determine a transmission route of the private line service in a province corresponding to the first platform, and send the identifier of the selected first core layer device to an opening device of the private line service. And after receiving the configuration information of the private line service, the first platform may send the configuration information of the private line service to the first access layer device, so that the first access layer device performs configuration according to the configuration information of the private line service to prepare for transmission of the private line service.
305. And the opening device of the private line service receives the identifier of the first core layer equipment sent by the first platform.
306. And the opening device of the private line service sends the identifier of the second access layer equipment to the second platform.
307. And the second platform receives the identifier of the second access layer equipment sent by the opening device of the private line service.
308. And the second platform sends the identifier of the second core layer equipment to the opening device of the private line service.
309. And the opening device of the private line service receives the identifier of the second core layer equipment sent by the second platform.
After determining the first core layer device and the second core layer device, the opening apparatus of the private line service may select a path that meets the requirement between the first core layer device and the second core layer device, and may specifically perform the following steps 310 to 312:
310. and the opening device of the private line service determines the corresponding path quality according to the routing hop count, the bandwidth utilization rate and the overhead value of each path between the first core layer equipment and the second core layer equipment.
In the embodiment of the present invention, description is given by taking the determination of any one of the N paths, for example, the path quality of the first path, as an example.
Specifically, the provisioning apparatus for dedicated line service may determine a routing hop count of the first path, where the routing hop count is equal to the number of devices that the first path passes through. And then determining the bandwidth utilization rate corresponding to each device via which the first path passes according to the real-time resource data, and determining the maximum bandwidth utilization rate in the bandwidth utilization rates as the bandwidth utilization rate of the first path. Finally, the device for opening the private line service can adopt the following formula:
a path quality score q for the first path is determined. Wherein r is the route hop count of the first path; r is the maximum route hop number in the route hop numbers of each path of the N paths; b is the bandwidth utilization of the first path; c is a pre-stored cost value of the first path, C isThe largest cost value in the cost values of each of the N paths.
It should be noted that, in the embodiment of the present invention, the path quality score q may indicate the condition of the path quality, and the smaller the score q is, the better the path quality is.
311. And the opening device of the private line service determines the failure rate of each path.
The activating apparatus of the private line service may determine a failure rate of each of N paths from the first core layer device to the second core layer device, and the determination of the failure rate of the first path is taken as an example for description.
Specifically, the device for opening the dedicated line service may determine, according to past fault data, a fault rate of each device in the devices through which the first path passes, and determine a fault rate of each link in links between the devices through which the first path passes. And the failure rate of the first path can be determined according to the failure rate of each device and the failure rate of each link.
It should be noted that, in the embodiment of the present invention, the failure rate may indicate the condition of the service quality of the path, and the smaller the failure rate is, the better the service quality of the path is.
For example, as shown in fig. 4, it is assumed that a first core layer device is M1, a second core layer device is M2, a first path from M1 to M2 passes through three devices, which are device D, E, F respectively, and two links exist between devices D, E, F, which are link 1 and link 2 respectively, so that the provisioning apparatus for dedicated line service can determine failure rates d1, d2, and d3 of device D, E, F respectively, and determine failure rates t1 and t2 of the two links respectively, and use the formula: and p is 1- (1-d1) (1-d2) (1-d3) (1-t1) (1-t2), and the failure rate p of the first path is determined.
312. And the opening device of the private line service determines a target path according to the path quality and the fault rate of the path and the category of the private line service.
After determining the path quality score and the failure rate of each of the N paths from the first core layer device to the second core layer device, the provisioning apparatus for the private line service may first determine the class of the private line service according to the class of the private line service, where the requirement of the private line service of each class on the service quality of the path is different, and each class corresponds to a preset failure rate, where the preset failure rate is a maximum allowable failure rate in the corresponding class. Then, the provisioning device of the private line service may determine, as candidate paths, paths having a failure rate less than or equal to a preset failure rate corresponding to the level of the private line service among the N paths, and determine, as a target path, a path having a minimum path quality score among the candidate paths.
It should be noted that, in the embodiment of the present invention, the correspondence between the category of the private line service and the class of the private line service may be prestored in the provisioning apparatus for the private line service. And the preset failure rates corresponding to different grades of the private line service can be obtained by analyzing the previous service and stored in the opening device of the private line service.
313. And the opening device of the private line service respectively sends routing information to the first core layer equipment, the second core layer equipment and the equipment through which the target path passes.
The routing information is used for transmission of the private line service.
According to the method for opening the private line service, after the access layer devices at the two ends are obtained, the corresponding core layer devices are determined, the optimal target path between the two core layer devices is determined according to the path quality and the fault rate of the path, and the routing information is issued, so that the private line service at the two ends is opened, and the problems that time and labor are consumed when optical fibers are directly connected and optical fiber bandwidth resources are wasted in the prior art are solved.
