Optical fiber network balancing routing method based on link dynamic loads

Abstract

The invention relates to the field of communication and specifically relates to an optical fiber network balancing routing method based on link dynamic loads. The method comprises the steps of S1, dividing a network into routing domains according to business demands, recording inter-domain nodes and links of different routing domains, setting identifiers and recording inter-domain link weights of the routing domains; S2, carrying out routing computation on the routing domains and updating a link state database; S3, dividing complete business flow into different intra-domain segments and marking service quality demands; S4, determining a layer of a power business initial node; S5, updating routing table information among different routing domains and carrying out segmental routing on different types of business; S6, expanding the segments of the business follow in the corresponding routing domains; S7, determining an entrance node address of a business termination routing domain, thereby finishing layered routing; and S8, combining the business routing segments in various routing domains, thereby forming a complete explicit routing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a balanced routing method for an optical fiber network based on link dynamic load. Background technique [0002] With the increase in the scale of the underlying bearer network of electric power communication, the unified planar management is no longer used, and the routing needs to be calculated in a hierarchical manner. Otherwise, it will bring a large computational burden to the centralized computing nodes. In each hierarchical routing domain, an independent routing calculation method is mostly used to determine the path of the service. However, among different routing domains, in order to reduce the communication overhead of the system, the topology and resource information inside each routing domain are not disclosed to the public, so centralized and unified routing optimization cannot be adopted. Although hierarchical routing can reduce the operating overhead of the...

Problems solved by technology

However, in the power communication network, there is a special problem. The established service connection is often not like the operator, there is a large number of service flows, and many established dedicated service channels only have a small amount of data. The bandwidth resources actually used by some service channels are not in the same order of magnitude as the reserved resources, which leads to a very serious bandwidth consumption of the power integrated data network

This problem mainly occurs in the difference between the statistical bandwidth and the reserved bandwidth
