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

Provided are service sending, receiving methods and devices. The service sending method includes that: one or more services are sequentially mapped into a target transmission frame; the target transmission frame is encapsulated into Optical Burst Units (OBUs), which carry one or more Transmission Adapter Units (TAUs), according to a sequence of mapping, wherein the one or more TAUs carried in the N OBUs are able to be formed into the target transmission frame, and each TAU carries a data fragment of the one or more services; N is a positive integer; an Identifier (ID) for indicating an identity of the target transmission frame is added into an overhead of each TAU; a length indicator for indicating the length of payload, occupied by the TAU, in an OBU is added into the overhead of each TAU; a position identifier for indicating a position of the TAU in the target transmission frame is added into the overhead of each TAU; and the N OBUs are sent to a destination node one by one according to a sequence of encapsulating. According to the solution, service transmission can be performed in an Optical Burst Transport Network (OBTN).
