Abstract
Each frame (500) being transmitted and received contains two frame sequence numbers. The first frame sequence number (501) comprises the sequence number of the frame being transmitted, while the second frame sequence number (502) comprises the sequence number of the next expected frame being received by the transmitter. Because each frame (500) contains a sequence number for the next expected data frame (502), transmitting circuitry (301, 302) will more quickly realize if a particular frame has not been received by the receiver. This reduces the number of idle frames needed to be transmitted at the end of the data session.
Claims13
A method comprising the steps of:
- receiving a first set of data having a first series of frame sequence numbers;
- and
- transmitting a second set of data comprising a second series of frame sequence numbers and the first series of frame sequence numbers.
A frame comprising:
- a first frame sequence number from a first data transmission session;
- a second frame sequence number from a second data transmission session;
- and
- data from the first data transmission session while containing no data from the second data transmission session.
A method comprising the steps of:
- receiving a first plurality of frames, the first plurality of frames comprising a first series of sequence numbers;
- and
- transmitting a second plurality of frames, the second plurality of frames comprising a second series of sequence numbers differing from the first plurality of sequence numbers, the second plurality of frames additionally comprising the first series of sequence numbers.
