| With the continuous development of Chinese Internet industry and technology,many commercial applications and related technologies are gradually realized IP functionalization.Based on the traditional circuit-switched data communications technology,transmission capacity is concerned which can not satisfy the characteristics of today's sudden peak and great change.In this context,PTN came into being,which is a technology that takes advantage of packet transmission as the core technology.PTN network transmission technology can satisfy our current Internet data transmission requirements,and the application of technology gradually becomes the main building of the Chinese Internet today.This article is mainly based on network transmission status of Pu'er Yunnan,which combined with the PTN network packet transport technology to optimize the network.The main contents as follows: First,this paper introduces the background,the purpose and significance of the research on the subject.Then,introduces the basic principles of PTN technology and analyze the principles,the definitions,the hierarchical structure technology and the technical characteristics of PTN.Secondly,to expound the networking strategies of PTN technology in detail,which discusses the core layers designed of PTN networking,the QoS policy and the synchronous clock strategy of PTN.After that,based on the actual movement of Pu'er optimized project,elaborates the further applies of PTN network technologies,and introduces the transmission of mobile network Status,analyze service bearer capability and demand.In addtion,the backbone,the building strategy layer,the convergence layers,the access layer of PTN network are analyzed in detail.And test the respective PTN performance of the program.The difficulties of this article are QoS policies,the protective layer on the PTN,and the backbone layer,the convergence layer,the access to technical oriented sub-layer of Pu'er PTN network.The paper analyzed their specific strategies in detail. |
