城域网高可靠性思考及系统优化实践

High reliability thinking and system optimization practice of metropolitan area network caused by network access

目前,IP城域网已成为电信运营商重要的业务承载网络,对于IP城域网而言,网络安全性和稳定性是核心也是关键。随着业务市场不断发展,人们对网络的质量和速度的要求更高,运营商之间的竞争越发激烈,为了在激烈的市场竞争中取得优势,就需要不断建设和优化网络环境。文章简要介绍了典型IP城域网网络架构,以及承载业务的重要性分析,针对传输光缆故障可能造成的用户上网卡顿现象,坚持以人民为中心的网络保障理念,深入分析IP城域网路由分布可能存在的安全隐患,系统提出IP城域网高可靠性优化实践方案,具有普适性。在本地某运营商施行后取得较好的成效,进一步增强了网络安全性、可靠性,提升了用户上网感知。

Currently,the IP metropolitan area network have become important business bearing networks of Telecom operator.The security and stability of network is becoming the core and key for that.People have higher requirements for the quality and speed of the network with the continuous development of the business market,and the competition among operators is becoming more and more fierce.we need to constantly build and optimize the network environment in order to gain an advantage in the fierce market competition.This article introduced the IP metropolitan area network and analysed the importance of carrying services briefly.Aiming at the phenomenon of users’Internet network freezes that may be caused by the failure of the transmission cable,we analyze the possible security risks in the IP metropolitan area network routing distribution deeply adhere to the peoplecentered network security concept.This article put forward a high reliability optimization practice plan for IP metropolitan area network systematically.It had achieved good results after being implemented locally.The network security and reliability was further enhanced,which also improved users’online perception.
