System Optimization Of Metropolitan Area Packet Transport Networks

Based on the developing trend of transport network in recent years,global network is changing very fast in a period.On the one hand,all kinds of telecommunication operators from the original voice type business into IP data class of the whole business,business transfer conveys the great transition from mainly for TDM to IP.On the other hand the traditional GSM network and CDMA network,and can't keep up with the trend of The Times,the transmission network business will carry large particles such as LTE,residential broadband,etc.The current network load is already unable to meet the needs of the development.So how to adjust the PTN network to achieve the required bandwidth,and guarantee the safety of network? These problems has become the current challenges of communication operators.This paper first studied the development of communication and the basic principle of PTN network.This paper will accord to the explosive growth of the entire network flow problem,put forward a means of flow separation,and on the basis of the existing network architecture,research carry business security problems,use effective protection technology PTN network reliability improvement scheme is put forward.From the two aspects,to optimize the existing packet transport network system,to achieve a strong support to the front desk business.
