Patent ID: 8111696

Claim:
A method of indicating a status of a transfer of data from a first device to a second device over a network, the data being transferred using one or more data frames, each data frame including a header having one or more bits and at least a part of the data being transferred, the method comprising: indicating, by the first device, a successful transfer status, without using a status frame containing no data being transferred, by setting a last bit of the one or more bits in the header of a last data frame of the one or more data frames to a first value; indicating, by the first device, a failed transfer status by setting the value of the last bit of the last data frame to a second value; discovering whether the second device receiving the data is adapted to check a value of the last bit of the one or more bits in the header of the last data frame to determine the status of the data request; and sending a status frame following the last data frame to the second device if the second device fails to check the value of the last bit.
