White Paper Modern cellular channels in 3G networks incorporate sophisticated power control and dynamic rate adaptation which can have a significant impact on adaptive transport layer protocols, such as TCP. Though there exists studies that have evaluated the... [07 Nov 2007]
TCP Self-Clocking
White Paper The authors propose a simple queueing model for one or more TCP transfers sharing a bottleneck link and examine its behavior when the buffer at the bottleneck is large compared to the bandwidth-delay product. [07 Nov 2007]
TCP Westwood With Bulk Repeat for Heavy Loss Environments
White Paper TCP Westwood (TCPW), a recently introduced sender only variant of TCP, was shown to be particularly efficient in high bandwidth, large propagation paths, with light random loss. That is, when the bandwidth delay product is high and some of the... [05 Dec 2007]
TCP Performance Improvement With ACK Pacing During a Long Lasting Loss Period in Wireless Data Networks
White Paper In wireless data networks, the TCP congestion mechanism can mistake a wireless channel error or blackout for congestion on the route. Several wireless TCP protocols have been proposed considering TCP performance degradation in wireless systems. [15 Jan 2008]
TCP Meets Mobile Code
White Paper This paper argues that transport protocols such as TCP provide a rare domain in which protocol extensibility by untrusted parties is both valuable and practical. TCP continues to be refined despite more than two decades of progress and the... [07 Nov 2007]
TCP-LP: A Distributed Algorithm for Low Priority Data Transfer
White Paper To this end, it develops TCP Low Priority (TCP-LP), a distributed algorithm whose goal is to utilize only the excess network bandwidth as compared to the "fair share" of bandwidth as targeted by TCP. The key mechanisms unique to TCP-LP congestion... [15 Jan 2008]
TCP With Adaptive Pacing for Multihop Wireless Networks
White Paper This paper introduces a novel congestion control algorithm for TCP over multihop IEEE 802.11 wireless networks implementing rate-based scheduling of transmissions within the TCP congestion window. It shows how a TCP sender can adapt its... [20 Dec 2007]
TCP Congestion Control Over 3G Communication Systems: An Experimental Evaluation of New Reno, BIC and Westwood+
White Paper One of TCP's key tasks is to react and avoid network congestion episodes which nor-mally arise in packet switched networks. This paper focuses on the UMTS wireless scenario and it reports a campaign of measurements that involved around 3000 flows... [20 Dec 2007]
TCP Tuning Guide for Distributed Application on Wide Area Networks
White Paper TCP uses what it calls the “congestion window”, or CWND, to determine how many packets can be sent at one time. The TCP “slow start” and “congestion avoidance” algorithms determine the size of the congestion window. [03 Jul 2008]
TCP WestwoodVT: A Novel Technique for Discriminating the Cause of Packet Loss in Wireless Networks
White Paper Conventional TCP in wireless environment cannot differentiate packet losses caused by network congestion from those caused by wireless link errors, thus, resulting in severe performance degradation. Accordingly, efficient operation of TCP in... [20 Dec 2007]
TCP-PARIS: A Parallel Download Protocol for Replicas
White Paper This paper presents TCP-PARIS, a novel parallel download protocol from multiple replicas to one receiver. Because the ideal partitioning of the transfer volume from each server is a dynamic and a difficult-to-predict function of network conditions... [20 Dec 2007]
TCP Rate Control
White Paper This paper presents TCP Rate Control, a new technique for transparently augmenting end-to-end TCP performance by controlling the sending rate of a TCP source. The `rate' of a TCP source is determined by its window size, the round trip time and the... [03 Jul 2008]
TCP Westwood: Bandwidth Estimation for Enhanced Transport Over Wireless Links
White Paper TCP Westwood (TCPW) is a sender-side modification of the TCP congestion window algorithm that improves upon the performance of TCP Reno in wired as well as wireless networks. The improvement is most significant in wireless networks with lossy links... [06 Dec 2007]
TCP-Friendly Many-to-Many End-to-End Congestion Control
White Paper The paper addresses the issue of TCP-friendly congestion control mechanism for many-to-many communication environment. The measurements have proved the proposed approach to be robust, efficient and TCP-friendly, as well as to provide fairness among... [27 Dec 2007]
TCP in Mixed Internet and Geo-Satellite Environments: Experiences and Results
White Paper The selected material includes: characterization of an induced error-prone satellite channel; results from an optimized non-congestion losses aware TCP (TCP Westwood) and its superior performance compared to TCP NewReno on such error prone scenario. [06 Dec 2007]
