Abstract:
1. An apparatus for preserving a frame sequence and distributing traffic in a multi-channel link, comprising: a transmitting buffer module for receiving frames from a higher layer and storing the frames; a first switching unit for switching the frames received from the transmitting buffer module to a plurality of paths; a sequence preservation buffer unit for outputting the frames after storing the frames in at least one sequence preservation buffer for a sequence preservation service time (SPST); a second switching unit for switching the frames output from the sequence preservation buffer unit to at least one idle transmitter at a termination point of the SPST; and a sequence preservation scheduler for predicting a transmission service finish time according to frame length, determining the SPST on the basis of the predicted transmission service finish time, determining a sequence of available sequence preservation buffers and a sequence of available transmitters using the number of busy sequence preservation buffers, storing the frames, and the number of idle transmitters, and controlling scheduling of the first and second switching units and the sequence preservation buffer unit, wherein the sequence preservation scheduler compares a transmission service finish time for each of the frames with a previous service finish time (PSFT) for a previous frame with respect to each conversation, determines a transmission sequence of frames belonging to the same conversation on the basis of a transmission service time according to frame length, and performs scheduling of the frames.
