ABSTRACT:
An apparatus for reordering frames of data within an interface device of a receiving device. The present invention can switch context to allow frames associated with more than one sequence to be handled concurrently. A "Missing Frame Window" is generated and associated with each sequence. Each Missing Frame Window maintains a record of frames of a particular sequence received out of order. When a frame associated with a particular sequence is received out of order, a bit within the Missing Frame Window representing the "missing" frame is asserted to represent receipt of the out of order frame. The out of order frame is then stored to be transferred to a host in order upon receipt of those frames which must be transferred before transfer of the out of order frame.
