| 摘要 |
The present invention refers to a method and an apparatus for synchronizing operation in a communication network of the kind wherein the physical node-to-neighbor-node links of the network are combined into forming logical multi-access unidirectional links, on each of which data is transferred in a recurrent frame that is defined by a frame synchronization signal on the link and that is forwarded downstream on the link by the nodes attached to the link. According to the invention, a frame synchronization distribution spanning tree is defined for said network so as to span said network by regarding the network in terms of node-to-neighbor-node physical links branches, not by default limiting the structure of said spanning tree to follow the structure of said network in terms of it's logical multi-access unidirectional links. |
