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.

"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...
