电力通信网中引进MPLS技术的探讨

多协议标记交换技术(MPLS)融合了IP技术和ATM技术的各自的优点,是近年来提出的一种实现IPoverATM的较好的解决方案。该文介绍了MPLS的基本概念、工作原理和网络结构,分析了在电力宽带通信网中引进MPLS的必然性,并针对电力系统关键业务对传送性能的要求,阐述了如何在电力系统中利用MPLS技术构建电力宽带通信网。

MPLS(multiprotocol label switching) technology is a better solve scheme to achieve IP over ATM recently which combines the advantage of IP technology a nd ATM technology.This paper introduces the basic conception,working theory and network structure of MPLS,analyzes the necessity of introducing MPLS into electr ic wide-band communication net,and expounds how to use MPLS technology to const ruct electric wide-band communication net in power system aimed at the demand o f key service in power system to transmitting Performance.
