TCP Testing - Preventing Global Internet Warming
White Papers Do the new TCP congestion control algorithms and other changes have unfairness that could lead to congestion collapse? Testing multiple flows using applications (rsync and ftp) shows some unfairness exists when the bottleneck queue is large; but...

End-to-End Reliability In UMTS: TCP Over ARQ
White Papers The focus of this paper is end-to-end reliable transmission in UMTS environment where TCP, a reliable transport protocol designed to retransmit information in case of loss, is present at the mobile station as well as the wired portion of the network.

TCP Implementations And False Time Out Detection In OBS Networks
White Papers This paper compares Reno, New-Reno and Selective Acknowledgements (SACK), the three most common TCP implementations today in (future) optical burst switched (OBS) networks. All three TCP implementations react to a Time Out (TO) loss in the same way...

TCP Performance In Wireless Access With Adaptive Modulation And Coding
White Papers We study a wireless access system with adaptive modulation and coding (AMC) at the physical layer, finite-length queuing at the data link layer and a TCP protocol at the transport layer. We analyze the end-to-end TCP performance via a fixed-point...

TCP Performance Over End-to-End Rate Control And Stochastic Available Capacity
White Papers Motivated by TCP over end-to-end ABR, this paper studies the performance of adaptive window congestion control, when it operates over an explicit feedback rate-control mechanism, in a situation in which the bandwidth available to the elastic...

TCP And UDP Performance For Internet Over Optical Packet-Switched Networks
White Papers This paper studies packet aggregation and deflection routing as employed in OPS networks on the performance of upper layer Internet protocols represented by TCP and UDP. The results show that for both TCP and UDP, mixed-flow aggregation achieves...

TCP-LP: A Distributed Algorithm For Low Priority
White Papers To this end, this paper 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.
