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. An SCTP variant, called New-Reno SCTP is presented, which introduces three...

Analysis of Scalable TCP in the Presence of Markovian Losses
White Papers This paper first presents an approximate expression for the throughput of a long lasting Scalable TCP session when the losses are i.i.d.and due to window dependent errors. It then presents an analysis when the losses are due to Markovian window...

A TCP With Guaranteed Performance in Networks With Dynamic Congestion and Random Wireless Losses
White Papers It is well-known that TCP performs poorly in the presence of packet losses happening for reasons other than Internet congestion. One increasingly important source of such errors is wireless links. In this paper, networks are studied where the...

"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...

Insuring Against Backup Losses
White Papers Crawford Adjusters Canada had a number of reasons to go looking for a new backup and recovery solution. For starters, the company's aging backup process wasn't doing the trick anymore, and more and more clients were requiring proof of a solid...

Fast 802.11 Link Adaptation for Real-Time Video Streaming by Cross-Layer Signaling
White Papers The quality of real-time video streaming over wireless links is significantly reduced due to packet losses and delays caused by rapid changes of the link conditions. Together, these solutions will prevent packet losses and skipped frames, both of...

A Comparison of Mechanisms for Improving TCP Performance Over Wireless Links
White Papers Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant losses due to bit...

Enhancing Wireless TCP: A Serialized-Timer Approach
White Papers In wireless networks, TCP performs unsatisfactorily since packet reordering and random losses may be falsely interpreted as congestive losses. This causes TCP to trigger fast retransmission and fast recovery spuriously, leading to under-utilization...

Improving TCP Performance Over 802.11 WLAN With Radio Network Feedback
White Papers A new technique is proposed that enables TCP to distinguish wireless packet losses from congestion related packet losses. This is achieved by introducing a wireless enhancement proxy (WENP) at layer 3 in the base station that monitors the TCP...

Improving TCP Performance Over Mobile Wireless Environments Using Cross Layer Feedback
White Papers This is because such environments are prone to packet losses due to high bit error rates and mobility induced disconnections. TCP interprets packet losses as an indication of congestion and inappropriately invokes congestion control mechanisms...

A Machine Learning Approach to Improve Congestion Control Over Wireless Computer Networks
White Papers TCP is suboptimal in hybrid wired/wireless networks because it reacts in the same way to losses due to congestion and losses due to link errors. For this classifier to be useful in this application, it should satisfy both a computational constraint...
