By definition of RFC 2018, each SACK block has to be indicated by two 32-bit unsigned integers which may introduce significant extra load in reverse ACK path. Moreover, due to a 40-byte length limitation, when errors occur in sudden bursts it is noted that the available option space may not be sufficient to report all sequence blocks and sometimes some unnecessary retransmission may be resulted in...
Satellite link is generally featured by long propagation delay, large bandwidth-delay product (BDP) and high bit error rate (BER). This tends to make the conventional TCP suffer from performance degradation in satellite networks. Thus Forward Error Correction (FEC) scheme is suggested for error recovery over satellite channel and RFC 2488 suggests that TCP does not reduce its congestion window (cwnd)...
This paper proposes a new error and congestion control scheme using corruption-aware adaptive increase and adaptive decrease algorithm to improve TCP performance over wireless/heterogeneous networks. In the proposed scheme, the slow start threshold is estimated based on the amount of the received integral data as well as the amount of the received corrupted data as per round trip time interval, and...
