单向链路原理分析及解决方案研究

在电力信息网络中,核心层组网链路多采用冗余方式,存在单向链路.文章论述了单向链路产生的原因及对网络造成的影响,同时针对该现象提出相关技术手段并结合原理进行分析经过实践论证,在网络设备上应用DLDP或者UDLD等技术,实现对通信链路状态的综合控制和监测,能有效解决单向链路的存在所造成的网络异常和故障,达到消除网络运行潜在威胁的目的.为今后在多链路组网方式下,避免单向链路问题,提高通道稳定性、可靠性提供新技术和新思路

Unidirectional Link Principle Analysis and Solutions

In power information network,the core layer network link usually takes a redundant way,producing a unidirectional link.This article discusses the causes of the unidirectional link and its impact on the network,proposes techniques and analyzes the principle for the phenomenon.Practices proved that the application of the DLDP or UDLD technologies on network equipment can achieve comprehensive control and monitoring of communication link status,which effectively addresses network anomalies and faults caused by the presence of unidirectional links,so as to eliminate the potential threat for network operation.It provides new technologies and new ideas to improve the channel stability and reliability under multi-link networking in the future,avoiding the problems of unidirectional links.
