Problems solved by technology

Since this method is only an optimization method for static service resource consumption in the network, it cannot be applied to the optimization of dynamic service resource consumption
However, in the actual three-tier network system, static services and dynamic services often exist on the network at the same time, so the above two technologies cannot realize joint route selection and resource optimization of static and dynamic mixed services in the network

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , the concrete implementation method of the present invention is as follows:

[0042] Step 1, input network topology information and static services, according to Figure 4 The six simulation conditions of each layer are used to set the number of nodes, adjacent links, and interlayer links.

[0043] Step 2, select routes for static services and update network resources.

[0044] Static service routing is implemented using the routing algorithm that requests the largest amount of bandwidth first. The algorithm first selects the node pair with the largest total bandwidth request in the service matrix, and then selects routes for service requests between the node pairs one by one according to the Dijkstra method. This routing algorithm with the largest total requested bandwidth first can avoid too many service routing hops between no...

Abstract

The invention discloses a method for optimizing resources of a static-dynamic mixed service in a three-layer network, which mainly solves the problem of transmission of the static-dynamic mixed service resource in the three-layer network, and comprises the following steps of: 1) inputting three-layer network topology information and a static service matrix; 2) taking a priority routing algorithm of request bandwidth total maximum as static service routing; 3) taking an ant colony optimization-based integrated routing algorithm as dynamic service routing; 4) determining whether to call an interlayer or intralayer resource optimization method or not according to grade parameters of the dynamic service and the joint routing result; 5) performing network periodic triggering on the global resource scheduling and optimizing method based on the adaptive period of the load intensity; and 6) carrying out the algorithm running result. In the invention, by introducing transport network layering,the ant colony optimization-based dynamic service joint routing algorithm, an interlayer resource coordination mechanism and a tabu search-based static service re-grooming method, global network resource optimal utilization is improved, the false rejection rate of a user connection request is reduced, and the requirement of end-to-end quality of service (QoS) is met.

Description

technical field [0001] The invention belongs to the technical field of communication, and mainly relates to a resource optimization method for static and dynamic mixed services in three-layer network communication. Background technique [0002] The three-layer network generally refers to the three-layer structure of IP / SDH / WDM of the optical transport network. Its function is to integrate three types of networks with different constitutions and realize the transmission of services with different bandwidth granularity in the optical transport network. Because the service bandwidth granularity is much smaller than the optical transport network wavelength granularity, it is very important to optimize various resources in the three-layer network. At present, the three-layer network resource optimization methods seen mainly include "transport network resource optimization utilization method" and "method and device for allocating network resources". [0003] The patented technolo...
