电信传输网络PTN技术应用发展

Development of Telecom Transmission Network with PTN Technology Application

随着国家经济的腾飞和科学技术的高速发展,网络技术的革新也越来越迅猛。PTN技术在电信城域网建设中的应用开始越加广泛,并将电信网络技术提升到更新的层次。由于电信运营商传统的SDH/MSTP传输体系采用的是以TDM内核为基础的通道复用技术,这对于传输网络的IP化、宽带化、业务多元化等方向的发展带来了很大的限制。而PTN技术由于拥有更为灵活的特性和十分便捷的多业务支持,在网络兼容性以及系统安全性等方面拥有了很高的优越性,因此PTN技术的发展正好满足了电信传输网络发展的新需求,并成为新一代的主流传输技术。文章主要针对PTN技术在传输网中的应用进行探究,阐述了这一领域的发展方向。

With the rapid development of national economy and advance of science and technology, the innovation of network technology is also more and more swift and violent. More applications of PTN technology appear in telecom network construc-tion, ascmds the telecommunication network technology to a higher level. Because of the SDH/MSTP transmission system of telecom carriers is the farditional channel multiplexing technology based on TDM kernel, it limits the development for the IP transmission network, broadband, business diversification direction, PTN technology with more flexible and convenient service support, network compatibility and system security aspects have a great advantage, so the development of PTN technology just to meet the new demand of the development of telecommunication transmission network, and become the mainstream trans-mission technology of the new generation. In this paper, the application of PTN technology in transmission network is resear-ched, and the development direction of this field is expounded.
