Study On Enlarged Capacity Plans Of A's Metropolitan Area Communication Transmits Network Based On Graph Theory

In the context of increasing communication demand,various high-speed bandwidthbusiness has emerged.On the one hand,it brings convenience and convenience for people's work and life,and on the other hand,it is a great test for the carrying capacity of communication network.Communication network in the process of construction to be adapted to the dynamic of business increasing bandwidth demand,the operator of the problems often encountered in the daily production,the Marketing Department with the customer to negotiate successfully the new business requirements,pass requirements to construction and maintenance department,found that the cause of the new business due to the limited network capacity,cause business is difficult.This article is based on a certain operator local transmission under the background of metropolitan area network,combined with the characteristics of the network of specific objects and logic of abstract modeling ideas,the network from a complex chaotic entity gradually abstracted as can research model;Coupled with an actual customer business requirements,detail when network face due to capacity problems lead to open new business difficulties,how to use network analysis method in operational research,expansion and quickly find bottlenecks point and formulate solutions;Then,in the process of implementing the scheme,the specific problems and causes of the impact on the project progress are analyzed by using the single codename network graph and the critical path method,and the method of progress control is given.Finally,we ensure that the expansion solution can realize the business needs of customers without affecting the construction of other projects on the network.Relying on the support of relevant theoretical basis,the construction and maintenance personnel of communication operators can be reasonable and reliable in their daily work.Not only can be done in the face of emergency network bottlenecks and quickly solve,to identify the needs of the business can also achieve the ceiling in network,give the rationalization suggestion to the construction department after completed at a lower cost of the expansion of the network.
