 PTN网络支持的保护方式分为以下三大类:
  (1)PTN网络内的保护方式

  PTN网络内的线性保护包括单向/双向1+1路径保护、双向1︰1或1︰N (N >1)路径保护、单向/双向1+1 SNC/S保护和双向1︰1 SNC/S保护,应至少支持双向1︰1保护机制。

  PTN网络内的环网保护包括Wrapping和Steering两种保护机制,应至少支持一种环网保护机制。

  (2)分组传达网与其他网络的接入链路保护

  TDM/ATM接入链路的1+1或1︰N保护。

  以太网GE/10GE接入链路的保护,即链路聚合组(LAG)。

  (3)双归保护

  PTN网络内保护和接入链路保护相配合,实现在接入链路或PTN接入节点失效情况下的端到端业务保护。具体实现机制待研究。
