Research On Network Improvement Of The Network Planning

The Quality of Service (QoS) Providing System, Traffic Engineering, andNetwork Planning are three approaches by which computer networks can be improved.Initially, when Internet started to develop, Internet Service Providers satisfied therequirements of customers only by augmenting network devices. In the late 20thcentury, with a view of mapping network traffic to physical topology rationally,Traffic Engineering research became a focus in the field of network research, in orderto equipoise load, enhance network devices use ratio, consequently improve networkperformance finally. With the appearance of new network application (eg. video meeting, phonetictransmission), a complete set of QoS Providing System must be established urgently,in order to satisfy quantificational network performance and requirement. The QoSProviding System arouses comprehensive attention, network group bring forwardmulti-QoS Providing System accordingly. Basing on the analysis of network developmental current and study status quoapplying to new type network QoS Providing System, the paper summarizes thenetwork planning study theoretically, discusses the factors in the study of networkimprovement, brings forward static routing scheme and bandwidth use strategyapplying to network improvement, presents the genetic algorithm scheme insolving network improvement of the network planning concretely, establishesnetwork improvement mathematics model, analyzes network improvement ideacommonly, presents the overall flow of the genetic algorithm in network improvementaccordingly and the details of all module, which mainly include initialization,topology coding, fitness counting, connectivity testing and mending, genetic strategyand terminating condition. Finally the paper proves that the algorithm is feasible andpreferable by theoretical deduction and computer simulation. As now the research of new type network planning is just on the start spot. Fromthe existing study we can conclude, network planning study integrating trafficengineering is a new study field worthy of probe, and it has important theoreticalmeaning and practically value.
