城域数据节点远距离接入的实施策略研究

Implementation Tactics of the Remote Accessing of Metro Data Nodes

目前部分数据网络建设较为滞后的市县和边远地区存在数据节点远距离接入的需求,包括远端IP节点的接入、用户接入交换机接入、远端DSLAM的接入,本文在分析网络现状和数据传输新技术的发展情况的基础上,结合城域接入产品的市场情况,讨论各种可行的解决方案,从而提出相关实施方案和策略。

This paper centers on the construction of the IP metro data networks of China Telecom,and is aimed at meeting the requirements of data nodes' remote accessing in some lagging areas or outlying cities and counties.The requirements include the accessing of remote IP nodes,the accessing of user exchanger and the accessing of remote DSLAM.On the basis of analyzing the current situations and the developments of new technologies in data transmission area,we take the accessing product market into consideration,thus discuss various kinds of feasible solutions,and suggest our implementing schemes and tactics.
