- Linux Beats Windows! - Or the Worrying Evolution of TCP in Common Operating Systems
- For a long time, operating system designers have followed the recommendation of the IETF for TCP congestion control. Lately, this has changed: the Linux kernel uses BIC-TCP by default since June 2004, and Compound TCP is going to be a part of Microsoft Windows Vista, where it is likely to...

- Understanding TCP Over TCP: Effects of TCP Tunneling on End-to-End Throughput and Latency
- TCP tunnel is a technology that aggregates and transfers packets sent between end hosts as a single TCP connection. By using a TCP tunnel, the fairness among aggregated flows can be improved and several protocols can be transparently transmitted through a firewall. Currently, many applications such as SSH, VTun, and...

- An Analysis of TCP Through Simulation
- This paper is an analysis of TCP and its variations through the use of simulations. The NS-2 network simulator was used to help understand the behaviors and characteristics of TCP variants. Two different experiments were set forth. The first varied different load conditions; the second varied queuing algorithms. The TCP...

- Experimental Evaluation of TCP Protocols for High-Speed Networks
- In this paper we present experimental results evaluating the performance of the Scalable-TCP, HS-TCP, BIC-TCP, FAST-TCP and H-TCP proposals in a series of benchmark tests. In summary, we find that both Scalable-TCP and FAST-TCP consistently exhibit substantial unfairness, even when competing flows share identical network path characteristics. Scalable-TCP, HS-TCP, FAST-TCP...

- A Uni?ed Framework for Modeling TCP-Vegas, TCP-SACK, and TCP-Reno
- This paper presents a general analytical framework for the modeling and analysis of TCP variations. The framework allows the modeling of multiple variations of TCP, including TCP-Vegas, TCP-SACK, and TCP-Reno, under general network situations. In particular, the framework allows us to propose the first analytical model of TCP-Vegas for arbitrary...

- Augmented Split-TCP Over Wireless LANs
- This paper introduces a new split-TCP approach for improving TCP performance over IEEE 802.11-based wireless LANs. TCP over wireless LANs is not aggressive, which is a fundamental reason for poor performance. This paper proposes augmented split-TCP (AS-TCP) to mitigate this problem. The scheme extends the split-connection approach that divides a...

- The Effect of Reverse Traffic on the Performance of New TCP Congestion Control Algorithms
- Several new TCP congestion control algorithms have been proposed to speed up the TCP over very fast networks. All these algorithms propose their own modifications of the increasing/decreasing phases of classic Reno/NewReno TCP. On the other hand, all of them preserve the self-clocking mechanism, which is a fundamental part of...

- Is Tampered-TCP Really Effective for Getting Higher Throughput in the Internet?
- This paper examines the effectiveness of tampered-TCP whose congestion control mechanism has been modified by malicious users for higher than the normal TCP throughput. This paper focuses on a tampered-TCP in which the increase and decrease ratio of the congestion window size were changed during the congestion avoidance phase. The...

- Use of Competition Detection in TCP for Fair and Effective Utilization of Network Bandwidth
- The fairness (or TCP-friendliness) of recent high-speed TCP proposals for high bandwidth-delay product networks is generally poor. The authors believe that the lack of TCP-friendliness of high-speed TCP proposals stems from their ineffectiveness in detecting competing TCP flows. The paper suggests a competition detection mechanism for a single TCP flow...

- Adaptive Aggregated Aggressiveness Control on Parallel TCP Flows Using Competition Detection
- This paper presents a competition detection mechanism for parallel TCP flows and uses this to propose a new parallel TCP congestion control scheme called Adaptive TCP-P (A-TCP-P). A-TCP-P automatically controls the aggregated aggressiveness of parallel TCP flows to fairly share network bandwidth with single TCP flows independently from the number...

The paper compares Tahoe and Reno TCP, the two most common reference implementations for TCP, with two modified versions of Reno TCP. The first version is New-Reno TCP, a modified version of...

- TCP-PR: TCP for Persistent Packet Reordering
- Most standard implementations of TCP perform poorly when packets are reordered. This paper proposes a new version of TCP that maintains high throughput when reordering occurs and yet, when packet reordering does not occur, is friendly to other versions of TCP. The proposed TCP variant, or TCP-PR, does not rely...

- TCP Westwood: Bandwidth Estimation for Enhanced Transport Over Wireless Links
- 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, since TCP Westwood relies on end-to-end bandwidth estimation to discriminate the...
