TCP Smart Framing: A Segmentation Algorithm To Reduce TCP Latency
White Papers Without modifying the TCP congestion control based on the additive-increase/ multiplicative-decrease paradigm, TCP-SF adopts a novel segmentation algorithm: while Classic TCP always tries to send full-sized segments, a TCP-SF source adopts a more...

TCP-Adaptive Reno For Improving Efficiency-Friendliness Tradeoffs Of TCP Congestion Control Algorithm
White Papers It has been recognized that TCP throughput deteriorates in networks with large bandwidth-delay-product and non-negligible packet losses. A number of protocols, such as High Speed TCP, Scalable TCP and TCP-Westwood have been proposed to address this...
