PTN大客户数据专线总头主备保护策略

摘要

为了提升PTN大客户数据专线组网的可靠性,实现常用组网方式中的故障自动迂回功能,本文提出了采用多种组合保护的策略,分别在基于MPLS-TP和基于PBB的两种方式中,有效实现专线总头主备保护.通过网络运行测试,采用上述策略,可以有效降低大客户专线平均故障历时40％以上.%In order to enhance the reliability of PTN convergence data line for key customers, and to realize the automatic roundabout on malfunction in usual networking modes, various combined protection strategies is proposed in this paper. The convergence data line can be effectively protected by the main standby switching protection strategies under MPSL-TP based and PBB based situations. The network operation test shows that the average fault duration of the data line for key customers can be effectively reduced more than 40％by using these strategies.
