Shangqiu Local Mobile Transmission Network Packetization Scheme Applied Research

As the 3G network, WLAN and group data network convection media business and high-speed broadband business increased demand, shang qiu local existing SDH network capacity cannot meet the needs of the new business and bearing. Packet transmission network (PTN) blend the metropolitan area transport network and the advantages of the metropolitan area data networks, aims to structure of telecommunication level for the grouping of bearing network connection. PTN technique is based on the packet switching, connection-oriented service transmission technology, to provide more efficient business bearing, have the strong protection, OAM and network management function. PTN flexible statistical multiplexing, strict QoS and time synchronization transmission network telecommunication level ability to meet the needs of the development of the network operators. This paper is dedicated to the study of PTN technology to local transmission network optimization as the technical means, through to the local metro transmission network for expansion and new transmission system, effectively improve the local transmission network structure, improve the network to the bearing capacity of the new business, strengthen the network operation safety of the whole business and enterprise competition ability.This paper first introduced the optical transmission network metropolitan area of technology evolution trend. On the 3G business, mobile Internet, three nets fusion and all the business operation of that drive, metro optical transmission network from rigid circuit transmission to the transfer of the grouping of business perception evolution trend irreversible.Second, the thesis of existing local transmission network status and existing problems of the analysis and research, and discussed the local transmission network of demand and the evolution of group a transformation of the technology choice. Around the goal of carrying demand for business circuit forecast, according to the transmission network structure and level, analysis to identify every level of bearing type and bandwidth business needs, we determine the main bearing PTN network bandwidth model business planning.Then, positioning in the transmission of the key-between local networks optimization man, clear the principle, structure optimization) planning, overall strategy, determine the transmission network construction group metropolitan area should be adopted on PTN technology network, according to the principle of the whole over the whole construction planning, take into account the GSM base stations, important group clients and broadband access needs, meet the overall carrying all kinds of data network business requirements.At last, this paper also shang qiu local groups to transmit network construction of some key techniques such as OAM, QOS and synchronization mechanism the implementation scheme of in-depth discussions.
