Abstract
Provided are a method and a device for implementing timeslot synchronization. The method includes: a master node performing timeslot synchronization training of an OBTN according to a timeslot length of the OBTN. By adopting the solution provided by the embodiments of the present disclosure, an FDL does not need to be considered in node design, the node design is simplified, the time precision of synchronization is improved and no loss is caused to optical efficiency.
Claims25
A method for implementing timeslot synchronization, applied to an Optical Burst Transport Network OBTN, comprising:
- performing, by a master node, timeslot synchronization training of the OBTN according to a timeslot length of the OBTN.
(canceled)
A master node, comprising:
- a synchronization module arranged to perform timeslot synchronization training of an Optical Burst Transport Network OBTN according to a timeslot length of the OBTN.
(canceled)
An agent master node, comprising:
- a second receiving module arranged to receive a first testing data frame and a second testing control frame from a master node;
- and measure and receive a second time delay that a third testing control frame and a second testing data frame return to the agent master node;
- and
- a second sending module arranged to forward the second testing control frame to a next node in the core path after a fixed time delay after the second testing control frame is received, and directly forward the first testing data frame to a next node in the core network after the first testing data frame is received;
- sequentially send the second testing data frame and the third testing control frame to a slave node in a non-core path in which the agent master node is located according to a timeslot length of an OBTN;
- and send the second time delay to the master node.

A slave node, comprising:
- a third receiving module arranged to receive a second testing control frame and a first testing data frame;
- and
- a third sending module arranged to forward the second testing control frame to a next node in a core path after a fixed time delay after the second testing control frame is received, and directly forward the first testing data frame to a next node in the core network after the first testing data frame is received.
