Congestion Control Mechanism of TCP for Achieving Predictable Throughput
White Papers This paper proposes a congestion control mechanism of TCP for achieving predictable throughput. It does not mean one can guarantee the throughput, while one can provide the throughput required by an upper-layer application at high probability when...

"De-Randomizing" Congestion Losses to Improve TCP Performance Over Wired-Wireless Networks
White Papers Currently, a TCP sender considers all losses as congestion signals and reacts to them by throttling its sending rate. With Internet becoming more heterogeneous with more and more wireless error-prone links, a TCP connection may unduly throttle its...

SCTP and TCP Variants: Congestion Control Under Multiple Losses
White Papers Inefficiency in the current specification of SCTP's congestion control is characterized, which degrades performance when there are multiple packet losses in a single window. First, a Fast Recovery mechanism, similar to that of New-Reno TCP, is...

Congestion Control: SCTP Vs TCP
White Papers This paper characterizes an inefficiency in the current speciation of SCTP's congestion control, which degrades performance (more than necessary to be 'TCP-friendly') when there are multiple packet losses in a single window.
