- Simulation-Based Comparisons of Tahoe, Reno, and SACK TCP
- This paper uses simulations to explore the benefits of adding Selective ACKnowledgments SACK and selective repeat to TCP. 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...

- SACK TCP Resilience Improvement With OPNET
- SACK TCP was designed to be capable of surviving multiple segment loss. This can occur during network congestion as well as network failure. 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...

- 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...

- TCP K-SACK: A Simple Protocol to Improve Performance Over Lossy Links
- This paper proposes k-SACK, a TCP variant that has considerably improved throughput characteristics over lossy links. A k-SACK source does not consider every packet loss as an indication of congestion. It uses the Selective Acknowledgement option to estimate a parameter lookaheadloss, which is used in congestion detection. The results demonstrate...

- TCP Pacing Revisited
- TCP pacing promises to reduce burstiness of TCP traffic and alleviate the impact of under-buffered routers and switches on flow throughput. However, current research literatures have not always agreed on the overall benefits of pacing. This paper re-examines the benefits and drawbacks of TCP pacing in light of new TCP...

- New Reno and SACK TCP Implemented in UMTS Networks: A Performance Analysis
- Universal Mobile Telecommunication System shortly UMTS is seen as the future mobile network. The use of the existing Transmission Control Protocol TCP as transport protocol in an UMTS environment is an understandable choice. TCP is the most commonly used transport protocol on the internet, and if it will be used...

- 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...

- Multiple Layer Error Control Over Wireless Links
- This paper compares the wireless performance of TCP with or without selective acknowledgments and in the presence or absence of a reliable link layer protocol, in order to determine whether link layer error control remains beneficial for TCP variants with improved error recovery capabilities, such as TCP SACK. The paper...

- M-TCP+: Using Disconnection Feedback to Improve Performance of TCP in Wired/Wireless Networks
- This paper proposes the M-TCP+ algorithm for heterogeneous wired/wireless networks. The algorithm is a modification of M-TCP that was proposed for deployment in mobile cellular networks. It is recommended that Internet hosts enable the delayed acknowledgement delayed ACK option to maximize network bandwidth by reducing the number of ACKs sent...

- OPNET Model of TCP With Adaptive Delay and Loss Response for Broadband GEO Satellite Networks
- Transmission Control Protocol TCP provides reliable transport services for Internet applications. Broadband Geostationary Earth Orbit GEO satellite networks play an important role in providing Internet access and network connectivity. They are characterized by long propagation delays and high bit error rates, which negatively affect TCP performance. The paper proposed a...

- Congestion Control in Linux TCP
- The TCP protocol is used by the majority of the network applications on the Internet. TCP performance is strongly influenced by its congestion control algorithms that limit the amount of transmitted traffic based on the estimated network capacity and utilization. Because the freely available Linux operating system has gained popularity...

- Use of TCP Decoupling in Improving TCP Performance Over Wireless Networks
- This paper proposes using the TCP decoupling approach to improve a TCP connection's goodput over wireless networks. The performance improvement can be analytically shown to be proportional to MTU=HP Sz, where MTU is the maximum transmission unit of participating wireless links and HP Sz is the size of a packet...

It has been enhanced repeatedly over 3 decades, and is now an integral part of every single computing facility. Internet is again on the move toward more reliable and robust network services. In...

- 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...

- C-Snoop: Cross Layer Approach to Improving TCP Performance Over Wired and Wireless Networks
- TCP continues to be the most important transport layer communication protocol. In heterogeneous wired and wireless networks, however, the high packet loss rate over wireless links can trigger unnecessary execution of TCP congestion control algorithms, resulting in performance degradation. Several solutions have been proposed to address the known problems that...

- 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...

- 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...
