The first embodiment is as follows:
in order to solve the conflict problem existing in the following two scenes in the OTN communication network: firstly, a batch rerouting electrical layer intelligent service scene; and secondly, a multi-user concurrent intelligent service scene.
In this embodiment, a method for adjusting domain-divided resources in a communication network is provided, as shown in fig. 1, the method includes:
s101: and the preset resource area is used for carrying out weight scoring on each network element in the preset resource area.
The network elements in the preset resource area support intelligent service deployment, and the network elements in the preset resource area comprise a first network element which creates the intelligent service and a second network element which does not create the intelligent service.
The intelligent service refers to an operation that can automatically sense network topology and environment change and needs to adjust a routing path.
The first network element is connected with a channel of the total bandwidth of the intelligent service as the edge of the intelligent service topology;
and the second network element is connected with a channel of the vacant total bandwidth as an edge of the vacant bandwidth topology.
The resource division of the network elements in the domain is determined according to the topology, and the topology can be changed according to the available resources and the used resources. In this embodiment, a pair of resource subdivisions is based on a reserved resource topology, and resource division also changes dynamically after topology changes.
The network element in the resource area is a network element for manually determining networking, and the network element needs to support intelligent service deployment; whether the network element supports intelligent service deployment is determined by the relevant equipment.
The network elements include a rerouting intelligent service network element and an electrical layer OTN network element for intelligent service rerouting.
And the rerouting intelligent service network element is the created intelligent service.

And the scoring of each network element in the resource area is to perform resource refinement management on the network elements so as to facilitate resource adjustment in the later period. And scoring each network element in the resource area is to calculate the total weight according to the position of the network element to be scored in the intelligent service topology, the priority intelligent service and the total available intelligent service resource weight in the vacant bandwidth topology, calculate the total weight M of each network element in the resource area according to the weighted scores of the network element to be scored, and sort according to the total weight M.
S103: and when the network elements in the preset resource area are operated concurrently, re-routing resources are distributed according to the time slot bandwidth values corresponding to the network elements.
When the intelligent service is modified and issued, time slot and bandwidth rate resources related to the intelligent service need to be locked. Concurrent operation means that a plurality of execution units are executed simultaneously and in parallel, and the access of concurrent execution units to shared resources (global variables, static variables and the like on hardware resources and software) easily causes competition.

In this embodiment, the bandwidth capability of the intelligent service channel is divided into three levels, and the value of Wn of the to-be-evaluated network element may be set to one of W high and W2, W medium and W low being 0.5, and all W medium and W1 are set when the user is undefined. The core trunk intelligent service may be set to W high-2, and in general, intelligent services above 40G may be set to W high. The division of the bandwidth capability level of the intelligent service channel can be more detailed, the important weight value of the intelligent service is high, and the unimportant weight value of the intelligent service is low. The weight setting of the intelligent service is set according to the user requirements and is not a fixed value.
The value of the bandwidth rate value Kn of the intelligent service channel is as follows: 1.25, 2.5, 5, 10, 40, or 100 in Gbps. And determining the n value in the Kn according to the number of the bandwidth rate values of the intelligent service channels, wherein the numerical values of the Kn are sorted from small to large, if 6 intelligent service channels with different rate values exist, the same rate value does not count the number, the n value in the Kn is 6, the maximum rate of the K is K6 which is 100, and the minimum rate of the K is K1 which is 1.25.

and the M3 is a total idle traffic rate, which is the sum of the total intelligent traffic channel bandwidths on the network element to be scored minus the occupied intelligent traffic channel bandwidth. In the spare bandwidth topology, the sum of the idle total flow of each network element is M3, and the calculation mode of the idle flow of each network element is that the occupied intelligent service channel bandwidth is subtracted from the total intelligent service channel bandwidth on the network element to be evaluated.
In order to rank all network elements in a resource area, and thereby find a network element corresponding to a time slot bandwidth value according to a modeling granularity, and obtain a time slot division scheme for the network element in the resource area, in combination with the embodiment of the present invention, there is also a preferred implementation scheme, and specifically, a corresponding time slot bandwidth value is allocated to each network element according to a weight score of each network element in the preset resource area, and the specific method includes:

nmax is the number of the time slot bandwidth values of the network element to be scored.
And the rerouting intelligent service port modeling granularity is related to the value of the timeslot bandwidth value Sn.
In this embodiment, the value range of the timeslot bandwidth value S is one or more of 1.25, 2.5, 5, 10, 40, or 100. The total weight score M determines the value of the value n of the slot bandwidth value Sn, the number of the slot bandwidth values Sn is 6 at most, and is S1-S6, and if n is 6 and nmax is 6, the values of Sn are S1 is 1.25, S2 is 2.5, S3 is 5, S4 is 10, S5 is 40, S6 is 100, and the unit is Gbps. If n is 2, nmax is 2, Sn is 1.25, S2 is 2.5, or S1 is 10, S2 is 40. The value of Sn is preset by a user.
S1 is the minimum time slot bandwidth value of the network element to be scored, Smax is the maximum time slot bandwidth value of the network element to be scored, S is sorted from small to large according to the numerical value of the time slot bandwidth value, and nmax is the number of the time slot bandwidth values of the network element to be scored.
The modeling granularity is related to the value of the slot bandwidth value Sn.
In this embodiment one, if the intra-domain rerouted intelligent services are all ODU1 intelligent services, the timeslot division may be based on 10G; if the intra-domain rerouting intelligent service has ODU1, GE and STM1 intelligent services, the time slot division is based on 1.25G, 2.5G or 10G; if the intra-domain rerouting intelligent services are all the FLEXE intelligent services of the 5G particles, the time slot division can be based on the 5G particles; and if the intra-domain rerouted intelligent services are all 40G large-granule intelligent services, dividing the time slot based on 40G.

And after the resource topology changes, the resource adjustment is triggered again, so that the network resource intelligent service topology and the vacant bandwidth topology are always in the optimal state. The preset time may be set to an empirical value in hours as a minimum unit. Any modification of the time slot modeling resources used during the time period, or an increase or decrease of network elements within the domain, is considered to be changed.
In this embodiment, in order to enrich the usage scenarios, in combination with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, the time slot bandwidth value in the resource area or the network element score in the resource area is calculated in a timed manner or manually triggered and calculated manually.
