Networking Strategy And Testing Of Local Transport Network Based On PTN Technology

As the basis of municipal transmission,the metropolitan area network provides a fast transmission platform and operating mechanism for carrying out data business.This model is the use of Ethernet switches and routers to complete implementation requirements are different,the difference is easy to cause in the whole business environment compatibility problem between the network and burden disequilibrium problem.This article analyze the Zhejiang Unicom traditional metropolitan area network,the network is established on the basis of MSTP,discussed on the basis of traditional network basic strategy for the development of PTN network,to solve the problem of enterprise's capital investment,management of data elements such as stability,analysis of the relationship between the MSTP network with PTN network.Then,how to realize the evolution of PTN network under the background of MSTP.In this paper,on the basis of Zhejiang Unicom company existing metropolitan area network,according to the future business demand forecasting,in the next few years based on PTN transport network technology,build an efficient,safe and stable metropolitan area mobile transmission network.PTN technology has the outstanding advantages,such as to show its superiority.Secondly,this paper introduces the development situation of packet transport network technology,the implementation principle of this technology,key technology need,and the main problems existing in the practical application has carried on the thorough analysis.With the help of direct investigation and actual analysis,this paper puts forward a more scientific approach to network construction.Zhejiang Unicom network conditions carry out the actual test,related to the stability of the network device,implementation,and business development status of these tests for the stability evaluation of mobile company transport network provides the necessary reference.Finally,this paper summarizes the research conclusions and gives the direction of future research.
