Abstract

本发明涉及光通信技术领域，尤其涉及一种波长选择技术。在一种可能的波长选择的方法中，目的节点设备从其上游的网络设备接收工作路径波长和保护路径波长的指示信息，所述工作路径波长和保护路径波长用于承载同一个业务，所述指示信息包括用于波长选择的波长参数；所述上游的网络设备为首节点设备或中间节点设备；然后，所述目的节点设备根据所述指示信息，确定所述工作路径波长和所述保护路径波长中要被关断的波长；随后，所述目的节点关断所述要被关断的波长，并从所述工作路径波长和保护路径波长中未被关断的波长中接收所述业务。本发明提供的方案通过传递指示信息，来保证目的节点选择正确的波长进行业务接收，提升了保护倒换的正确性。
