PTN network optimization simulation method and system

Abstract

The invention particularly relates to a PTN network optimization simulation method and a system. The method comprises steps that step 1, key indexes for quantitatively evaluating a PTN network are determined; step 2, a simulation model of the PTN network is constructed according to performance parameters of PTN network elements, optical cable distances among the network elements and a PTN network topology structure; step 3, the input data of the simulation model is determined according to the key indexes; step 4, the input data is inputted to the simulation model to carry out simulation calculation to acquire key index values used for evaluating quality of the PTN network; and step 5, whether the key index values are in a target value scope is determined, if yes, optimization simulation is ended, if not, the simulation model of the PTN network is optimized till the key index values outputted by the simulation model are in the target value scope. Through the method, optimization simulation of the PTN network can be realized.

Description

technical field [0001] The invention relates to the technical field of network evaluation and network simulation optimization, in particular to a PTN network optimization simulation method and system. Background technique [0002] The services carried in the communication network are gradually transitioning from voice services to data services. Correspondingly, China Mobile's transmission network has also developed from SDH to a PTN (Packet Transport Network)-based transmission network. The PTN transmission network based on MPLS-TP packet transmission adopts a connection-oriented transport layer network architecture. The OAM mechanism is added on the basis of IP / MPLS, which has high network survivability and scalability. [0003] At present, the PTN system is an important way to carry various services of China Mobile. The importance of the PTN network is self-evident, but how to judge and build a good PTN network currently mainly depends on the perceptual judgment of person...

Problems solved by technology

[0004] At present, for the construction of PTN network, the construction plan is mainly obtained through discussion by all parties involved in the network construction. The main considerations of the construction plan are the loop formation rate, network topology structure, network traffic satisfaction, and investment situation. There is no scientific, comprehensive and unified plan. Judgment criteria

Moreover, relying on experience and perceptual judgment to determine the PTN network construction plan, investment and construction will cause greater risks to investment
