Title: Data transfer method and apparatus that allocate storage based upon a received relative offset

Abstract: A method of using a frame sequence to transmit a data block from a transmitting device to a receiving device is disclosed. One step of the method includes generating a first frame of the frame sequence that includes a last portion of the data block and a relative offset which indicates a relative displacement between a first portion of the data block and the last portion of the data block. Another step of the method includes generating a second frame of the frame sequence that includes the first portion of the data block. The method also includes the step of transmitting the first frame of the frame sequence from the transmitting device to the receiving device before transmitting the second frame. Yet another step of the method includes receiving the first frame of the frame sequence from the transmitting device before receiving the second frame. Moreover, the method includes allocating a storage area for the data block, the storage area having a storage capacity that is based on the relative offset of the first frame. A network device which allocates storage for a data packet based upon a relative offset for a last portion of the data block is also disclosed.
