- TCP Probe: A TCP With Built-In Path Capacity Estimation
- Knowing the capacity of an Internet path is important for efficient network utilization, pricing, and management. Using the capacity information, one can provide better TCP congestion control, multimedia streaming, P2P peer selection, and overlay structuring. Capacity estimation has been extensively studied. Though current approaches have been able to provide fast...

- 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...

- Inline Network Measurement: TCP Built-In Techniques for Inferring End-to-End Bandwidth
- This paper introduces a method for measuring the available bandwidth in a network path between two end hosts using an active TCP connection. First it constructs a new measurement algorithm that uses a relatively small number of probe packets yet provides periodic measurement results quickly. Then it applies the proposed...

- A Simulation Study of Packet Path Diversity for TCP File Transfer and Media Transport on the Internet
- This paper studies the performance of TCP-based media transport when combined with Packet Path Diversity PPD in the Internet. A simple PPD-TCP transport scheme is presented where the ACKnowledgments ACKs from the receiver are duplicated and sent across independent network paths. It also investigates a PPD-TCP scheme where in addition...

- How Well Can TCP Infer Network State?
- The Transmission Control Protocol TCP has been the protocol of choice for many Internet applications requiring reliable connections. The design of TCP has been challenged by the extension of connections over wireless links. This paper ask a fundamental question: What is the basic predictive power of TCP of network state,...

- An Extension of the TCP Steady-State Throughput Equation for Parallel TCP Flows
- Almost a decade after its publication in, the steady-state throughput equation of TCP by Padhye et al. remains the most widely used method for calculating the throughput that a TCP sender obtains under certain environment conditions. While there is now a wealth of other models available, many of which are...

- A System Demonstration of ST-TCP
- ST-TCP (Server fault-Tolerant TCP) is an extension of TCP to tolerate TCP server failures. Server fault tolerance is provided by using an active-backup server that keeps track of the state of a TCP connection. The backup server takes over the TCP connection if the primary server fails. This paper provides...

- 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...

- Diagnosis of TCP Overlay Connection Failures Using Bayesian Networks
- When failures occur in Internet overlay connections today, it is difficult for users to determine the root cause of failure. An overlay connection may require TCP connections between a series of overlay nodes to succeed, but accurately determining which of these connections has failed is difficult for users without access...

- 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 Smart TCP Acknowledgment Approach for Multihop Wireless Networks
- Reliable data transfer is one of the most difficult tasks to be accomplished in multihop wireless networks. Traditional transport protocols like TCP face severe performance degradation over multihop networks given the noisy nature of wireless media as well as unstable connectivity conditions in place. The success of TCP in wired...

- 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...
