摘要： A protection method in the packet transport network is provided by the embodiment of the invention. A protection path for the service data flow bearing on the shared protection ring is set up in the method, wherein the protection path includes a loopback protection path and a source routing protection path. Firstly, a first service data flow is sent through the loopback protection path. Then a service data flow node stops sending a second service data flow following the first service data flow to the loopback protection path, and caches the second service data flow. When the first service data flow completely passes the service data flow node again, the cached second service data flow is switched from the loopback protection path to the source routing protection path. A relevant system and device are also provided by the embodiment of the invention. The invention can solve the disordering problem generated when the combination protection scheme of the loopback way and the source routing way is applied in the packet transport network.

摘要： A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow. When the first service data flow completely passes by the service data flow node again, the buffered second service data flow is switched from the wrapping protection path to the steering protection path. A corresponding device and a corresponding system are also provided. Therefore, a disordering problem that occurs when a combination protection solution of the wrapping manner and the steering manner is applied in the packet transport network is solved.
摘要翻译： 提供分组传输网络中的保护方法。 在该方法中为共享保护环承载的业务数据流建立保护路径，保护路径包括包裹保护路径和转向保护路径。 首先，通过包装保护路径发送第一服务数据流。 然后，业务数据流节点停止发送第一业务数据流到包装保护路径之后的第二业务数据流，并缓存第二业务数据流。 当第一业务数据流再次完全通过业务数据流节点时，缓存的第二业务数据流从缠绕保护路径切换到转向保护路径。 还提供了相应的设备和相应的系统。 因此，解决了在分组传输网络中应用打包方式和转向方式的组合保护方案时出现的无序化问题。
