Example Embodiment

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings. For the convenience of description, the present invention uses M=3 as an example to describe the implementation method, but the principle is also suitable for the case of M>3 or M=2. In order to facilitate the distinction between the link between adjacent nodes in the same layer and the two upper and lower adjacent interlayer node links, the present invention refers to the link between adjacent nodes in the same layer as the adjacent link between nodes. The link between two adjacent layer nodes is called the adjacent link between nodes.

[0063] Refer to figure 1 , The specific implementation method of the present invention is as follows:

[0064] In the first step, according to the actual network system of the transport network, the network structure used by the operator, or the fictitious network settings, the transport network is divided into 3 layers, from the...

Abstract

This invention discloses a method for laminating transmission nets, selecting joint routes and jointly optimizing multi-layer resource including the following steps: 1, expressing layering to the network, 2, jointly selecting routes according to the parameters of service request bandwidth and grade, link bandwidth usability, adjacent inter layer link transmission rate and hops, 3, calling the MRIS method based on the result of jointly selecting routes, 4, periodically calling the MRJS method to optimize the resource configuration, 5, carrying out the algorithm operation.

Description

technical field [0001] The invention belongs to the field of communication technology, and mainly relates to resource utilization technology in a communication network, in particular to a resource optimization method for a transmission network. technical background [0002] With the rapid development of telecommunication networks, computer networks and radio and television networks, the networks are showing a trend of mutual integration, and the network structure has undergone quantitative and even qualitative changes, and is evolving and transitioning to the next generation network NGN (Next Generation Network or NewGeneration Network). NGN is not a simple extension and superposition of the existing telecommunication network and IP network, but a transformation of the entire network framework and an overall solution. In order to protect existing network investment, the emergence and development of NGN is a gradual change rather than a sudden change. It is a network that rea...
