The method comprises: measuring, by a master node, the network ring length of an OBTN, and according to a measurement result, calculating the length of a data frame, the number of time slots in the data frame, the length of the time slots and the guard interval of the time slots; according to the calculated length of the data frame, the number of time slots in the data frame, the length of the time slots and the guard interval of the time slots, sending a testing data frame and a testing control frame to a slave node to conduct frame synchronization training and time slot synchronization training; according to a result of the frame synchronization training and a result of the time slot synchronization training, sending, by the master node, a data frame and a bandwidth map to the slave node; and according to a bandwidth request sent from the node, generating, by the master node, a new bandwidth map, and sending the new bandwidth map to the slave node.

Optical burst transport network, node, transmission method and computer storage medium

The present disclosure discloses a method for training time slot synchronization of nodes in an Optical Burst Transport Network (OBTN), a node device and a network. The method includes that: a node trains a reference time delay between receiving of a control frame and receiving of a data frame, wherein the data frame and the control frame are within one period; and the node trains a sending time slot between sending of adjacent data packets in the data frame.

Method for training time slot synchronization of nodes in optical burst transport network, node device and network

A method for bandwidth map update includes: after receiving a bandwidth report carried by a control frame, a master node newly establishing a bandwidth map, newly establishing a resource state table, and setting all resource states in the newly established resource state table to be available; adding a cross-master node transport channel drop allocation structure of the newly established bandwidth map in accordance with a cross-master node transport channel add allocation structure of a bandwidth map to be updated, and updating the resource state table; according to the bandwidth report carried by the control frame, allocating a wavelength and an optical burst timeslot one by one to a current bandwidth request, adding wavelengths and optical burst timeslots to the newly established bandwidth map, generating a new bandwidth map, and updating the resource state table; and distributing the control frame carrying the new bandwidth map to slave nodes hop by hop.
