Augmented Split-TCP Over Wireless LANs
White Papers This paper introduces a new split-TCP approach for improving TCP performance over IEEE 802.11-based wireless LANs. This paper proposes augmented split-TCP (AS-TCP) to mitigate this problem. The paper compares AS-TCP with both normal TCP and I-TCP...

TCP Congestion Control With A Misbehaving Receiver
White Papers This paper explores the operation of TCP congestion control when the receiver can misbehave, as might occur with a greedy Web client. The paper first demonstrates that there are simple attacks that allow a misbehaving receiver to drive a standard...

SACK TCP Resilience Improvement With OPNET
White Papers This paper studies the resilience behavior of SACK TCP in both cases and finds that there is a critical point at which the behavior of SACK TCP changes significantly. This paper documents a change to the OPNET version of SACK TCP that improves the...

Machine-Learnt Versus Analytical Models Of TCP Throughput
White Papers This paper first studies the accuracy of two well-known analytical models of the average throughput of long-term TCP flows, namely the so-called SQRT and PFTK models, and show that these models are far from being accurate in general.

Inverting Sampled ADSL Traffic
White Papers The method presented in this paper proves efficient for TCP flows composed of more than 20 packets. These flows contribute 95% to the global TCP bit rate and a precise knowledge of their characteristics is necessary for charging issues.

On The Modeling Of TCP Latency And Throughput
White Papers Combining these short and steady state models, the paper proposes an extensive stochastic model which can accurately predict the throughput and latency of the TCP connections as functions of loss rate, round-trip time (RTT), and file size.

TCP NewReno: Slow-But-Steady Or Impatient?
White Papers This paper compares the throughputs of two different TCP NewReno variants, namely Slow-but-Steady and Impatient. The models build upon prior work on TCP Reno throughput modeling, but extend this work to provide an analytical characterization of the...

Dealing With Sudden Bandwidth Changes In TCP
White Papers This paper proposes a novel technique to deal with sudden bandwidth changes in TCP. To resolve this problem, the paper proposes to modify the current TCP algorithm to include a new phase, called Fast Adaptation (FA).

TCP Westwood: Analytic Model And Performance Evaluation
White Papers This paper presents a performance model of TCP Westwood (TCPW), a new TCP protocol with a sender-side modification of the window congestion control scheme. TCP Westwood controls the window using end-to-end connection bandwidth share estimation.

An Experimental Investigation Of The Congestion Control Used By Skype VoIP
White Papers The paper has found that Skype flows are somewhat elastic, i.e.they employ some sort of congestion control when sharing the bandwidth with unresponsive flows, but are inelastic in the presence of classic TCP responsive flows, which provokes...

Providing Soft Bandwidth Guarantees Using Elastic TCP-Based Tunnels
White Papers This paper presents a novel approach that enables two edge/border routers - which the paper calls Internet Traffic Managers (ITM) - to use an adaptive number of TCP connections to set up a tunnel of desirable bandwidth between them.
