Abstract
Providing transport protocol within a communication network having a lossy link. The receiver distinguishes between packets received with non-congestion bit errors and packets having been not at all received due to congestion. When packets are received with non-congestion bit errors, the receiver sends selective acknowledgments indicating that the packets were received with bit errors while suppressing duplicate acknowledgments to prevent the invocation of a congestion mechanism.
Claims1
A method for controlling transmission performance in a communication network having a base station relaying a plurality of packets to a receiver, each of said packets having a payload without error correction bits and a header comprising an address and a sequence number, said header having error correction bits, said method comprising the steps of:
- identifying a received packet having a bit error at said receiver;
- determining at said receiver whether said bit error occurs within a packet header of said received packet;
- correcting said bit error at said receiver if the bit error occurs within said packet header;
- and
- marking said received packet as received in error at said receiver if the bit error does not occur within said packet header.
