PTN Technology And Its Application In Yunfu Mobile Construction

Into the information age of the 21 st century, explosive, people to produce information of gaining information demand is higher and higher, more and more kinds, more and more convenient way, from the previous simple language service demand to the present language and data pay equal attention to the needs of the business on even data, including data business requirements including high-speed Internet access, video, IP telephone (VoIP) and other business, these are IP data services. Also with China's 3 G network construction and all the business operation, the advent of the high speed data and multimedia application proportion, further improve the data based on IP man become the subject of transfer business, mobile broadband, transmission network will be inevitable development direction,3 G base station the bearing will also from the traditional E1 interface to a FE interface evolution, especially as the 3 G base station number of scale development, increase, Ethernet data load MSTP network to bring enormous pressure, operators based on SDH/MSTP bearing technology is difficult to meet the 3 G network development needs, and so, bearing the business of the group is the IP an unstoppable trend and choice, as the business of the drive to the IP network development, the IP packet transmission network (PTN) will gradually replace traditional SDH network into the next generation of transmission network/MSTP the mainstream IP bearing technology is the inevitable choice of telecom operators.This paper focuses on the technology PTN principle, key technology, network structure, application mode, network scheme and the network planning were analyzed; Also studied PTN equipment the main function and performance indicators. Through the analysis of the mobile network structure, yunfu PTN network planning, construction and application PTN principle, puts forward the network schemes, and in the implementation of construction PTN. At last, the paper analyzes the_problems existing in PTN commercial, and put forward the solution. These for future large-scale construction of PTN and application has the very vital significance.
