Abstract

本发明公开了一种保护倒换方法及节点，该方法包括：中间节点接收上游邻居节点发送的第一保护倒换请求消息，第一保护倒换请求消息用于请求激活第一保护路径，中间节点为第一保护路径上的节点；中间节点确定第一保护路径需要占用N1个时隙，按照预设的顺序从N2个可用时隙中为第一保护路径选择第一组时隙，第一组时隙的时隙个数为N1，N2个可用时隙为中间节点与下游邻居节点之间的链路所包含的可用时隙，N2大于等于N1；中间节点向下游邻居节点发送第二保护倒换请求消息，第二保护倒换请求消息用于请求下游邻居节点基于第一组时隙完成下游邻居节点到中间节点在第一保护路径上的交叉连接。采用本发明，可以提高时隙资源的利用率。
