Abstract
In the present technique of round trip time management, an acknowledgment packet received (204) on a wireless network is first buffered (210) to a memory buffer. A time delay is then added (214) to an assigned departure time of the acknowledgment packet, which at least substantially stabilizes the round trip times of a transmission control protocol transmitter. As a result, a congestion control feature of the transmission control protocol transmitter is prevented from being triggered by a false detection of a network congestion.
Claims19
A method of managing round trip time of a transmission control protocol comprising:
- receiving an acknowledgement packet;
- buffering the acknowledgement packet into a memory buffer;
- and
- adding a time delay to an assigned departure time of the acknowledgement packet.
An apparatus for managing round trip time of a transmission control protocol comprising:
- a memory buffer having an acknowledgement packet;
- and
- a time delay adder circuit operably coupled to the memory buffer and having an added delay value to an assigned departure time to the acknowledgement packet.
A system of managing round trip time of a transmission control protocol comprising:
- a transmission control protocol transmitter;
- a transmission control protocol receiver;
- and
- a controller circuit operably coupled to the transmission control protocol transmitter and the transmission control protocol receiver, wherein the controller circuit buffers at least one acknowledgement packet from the receiver and adds a delay to an assigned departure time of the at least one acknowledgement packet for transmission to the transmitter.
