| 发明名称 | Method and means for state transition of Ethernet linear protection switching | ||
| 摘要 | The present invention relates to state transition, especially relates to method and means for state transition of Ethernet linear protection switching. It is provided a method of state transition for a local end of a protection group of Ethernet linear protection switching in a local network element, and the method comprises receiving a first message configured to change the state of the local end with a first state, the first message being overridden by the first state; receiving a second message configured to change the state of the local end; determining a second state of the local end on the basis of the first message and the second message; and changing the state of the local end into the second state. In this way, there will be no unnecessary state transition and then no traffic loss caused by the unnecessary state transition. | ||

| 主权项 | 1. A method of state transition for a local end of a protection group of Ethernet linear protection switching in a local network element, comprising the steps of: receiving, at the local end, a first message configured to change the state of the local end with a first state, the first message being overridden by the first state; receiving, at the local end, a second message configured to change the state of the local end; determining, at the local end, a second state of the local end on the basis of the first message and the second message; and changing, at the local end, the state of the local end into the second state. | ||
