OTN ring network service optimization method, computer system and server

Abstract

The invention provides an OTN ring network service optimization method, a computer system and a server. Load sharing of the looped network is subjected to balance judgment by calculating the varianceof the link channel utilization rate of the looped network. The method comprises the steps of: firstly, when a single service is opened, calculating the channel utilization rate of a link, judging whether the channel utilization rate of the link exceeds 100% or not, if the channel utilization rate of the link does not exceed 100%, calculating corresponding looped network variances during forward path and reverse path of the current service, and selecting the link channel with a small variance as the link channel of the current service; and storing the corresponding path into the link matrix A.By comparing the variance of the forward path and the reverse path of each service, the link channel planning of the whole looped network is ensured to be balanced after the current service planningis completed, and meanwhile, the link channel planning of the whole looped network is ensured to be balanced after each service is planned in sequence.

Description

Technical field [0001] The present 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 operator’s OTN network’s path planning is basically in the automatic calculation process. If it is not restricted, the path usage will be unevenly distributed, and the channel usage of the link will fluctuate very greatly, which will lead to the ring network part The link channel load fluctuates greatly, and the problem of imbalance occurs. [0003] The prior art uses hierarchical modeling of the OTN communication network and specifies indicators such as transmission delay requirements, reliability requirements, etc., and ultimately can reduce the appearance of high-load optical layer path nodes, and can be balanced as much as possible. During path planning, the calculation of the algorithm is relatively mechanized, and the path with ...

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
