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). |
