otn ring network service optimization method, computer system and server

Abstract

The present invention provides an OTN ring network service optimization method, a computer system and a server. By calculating the variance of the link channel usage rate of the ring network, the balance of the load sharing of the ring network is judged. First, when a single service is opened, first Calculate the link channel usage rate to determine whether there is a link whose channel usage rate exceeds 100%. If there is no link channel that exceeds 100%, calculate the ring network corresponding to the forward path and reverse path of the current service Variance, select the link channel with small variance as the link channel of the current service. And store the corresponding path into the link matrix A. By comparing the variance of the forward path and the reverse path of each service, it is ensured that after the current service planning is completed, the link channel planning of the entire ring network is balanced, and at the same time, after the planning of each service is completed in turn, The link channel planning of the entire ring network is balanced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an OTN ring network service optimization method based on link channel load sharing and balancing. Background technique [0002] The path planning of the operator's OTN network is basically in the process of automatic calculation. If there is no restriction on it, the usage of the path will be unevenly distributed, and the channel usage of the link will fluctuate greatly, resulting in the ring network part. The link channel load fluctuates greatly, resulting in unbalanced problems. [0003] In the existing technology, the layered modeling of the OTN communication network is started by specifying the transmission delay requirements, reliability requirements and other indicators, and finally the occurrence of high-load optical layer path nodes can be reduced and balanced as much as possible. When performing path planning, the calculation of the algorithm is relatively...

Problems solved by technology

[0002] The path planning of the operator's OTN network is basically in the process of automatic calculation. If there is no restriction on it, the usage of the path will be unevenly distributed, and the channel usage of the link will fluctuate greatly, resulting in the ring network part. The link channel load fluctuates greatly, resulting in unbalanced problems

[0003] In the existing technology, the layered modeling of the OTN communication network is started by specifying the transmission delay requirements, reliability requirements and other indicators, and finally the occurrence of high-load optical layer path nodes can be reduced and balanced as much as possible. When performing path planning, the calculation of the algorithm is relatively mechanized, and it cannot further process the path with certain rules, and the existing technology only estimates the variance of the utilization rate of the link channel by presetting the peak value of the utilization rate, which has limitations. , when encountering a complex network topology, or an uncertain number of services and ring network nodes, the existing methods cannot solve the problem very well

[0004] The current service configuration only considers finding the shortest link channel between two points for service provisioning when planning service link channels, and lacks a balanced planning for channel load sharing of the entire ring network, which will greatly The load pressure on some link channels is very heavy, and a single link channel will bear huge transmission pressure. Once a problem occurs on this link channel, it will cause a large number of services to fail
