<p>Provided are a service transmission method of an optical burst transport network (OBTN), source node and destination node, the service transmission method applied to the source node comprising: acquiring the bandwidth map of a target service from a received control frame; determining, from the bandwidth map of the target service, various wavelengths used by optical signals for transmitting the target service, and the time slot position of the target service in the optical signals of various wavelengths; encapsulating the target service into a data frame, and mapping the data frame encapsulated with the target service into the optical signals of various wavelengths according to the time slot position via electro-optic conversion; and transmitting each optical signal to a destination node according to the corresponding wavelength. The solution of the present invention transmits target service via the optical signal of various wavelengths, thus taking full advantage of OBTN bandwidth resources.</p> |
