Resource utilization optimization method for transfer network

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...

Problems solved by technology

[0005] This method has the following defects: 1) it is only applicable to the ring network in the transport network; 2) it is only applicable to the two-level structure of ring subnet, edge subnet and core subnet; Changes in the network topology to maximize the use of network resources; 4) User services are not graded, which cannot better guarantee the service quality of high-level services and maximize the benefits of network operators

This invention application has the following defects: 1) Network resource optimization is not performed according to the user's service request, and resource optimization cannot be achieved from the network as a whole; 2) It is not suitable for performance evaluation of the network to be built

[0007] In short, the traditional transport network routing selection and resource management do not take into account the layering of the network and the interaction between different layers of networks, the difference in operator revenue generated by different types of users and different types of services, and cannot realize the rational use of existing network resources. It is also impossible to design a network to be built with a more reasonable utilization of network resources, resulting in the defects of low overall resource utilization and reliability of the network, and a high rejection rate of user calls or service requests
