- A Comparison of TCP and SCTP Performance Using the HTTP Protocol
- This paper discusses using HTTP over SCTP as an alternative to the traditional HTTP using TCP as the transport layer protocol. Some performance tests using modified versions of thttpd and httperf are performed and the results indicate that SCTP using multiple streams can improve performance on heavily congested lines compared...

- HTTP Transfer Latency Over SCTP and TCP in Slow Start Phase
- Current web applications use HTTP Hyper Text Transfer Protocol over TCP Transmission Control Protocol to retrieve objects over the Internet. SCTP Stream Control Transmission Protocol is a recently proposed transport protocol with very similar congestion control mechanisms as TCP, except the initial congestion window during the slow start phase. This...

- SCTP and TCP Variants: Congestion Control Under Multiple Losses
- Inefficiency in the current specification of SCTP's congestion control is characterized, which degrades performance when there are multiple packet losses in a single window. An SCTP variant, called New-Reno SCTP is presented, which introduces three modifications. First, a Fast Recovery mechanism, similar to that of New-Reno TCP, is included to...

- QoS-Enabled Internet-on-Train Network Architecture: Inter-Working by MMP-SCTP Versus MIP
- Internet-on-the-train is a rising concept in the last few years. Several trials in different countries have proved the feasibility of offering Internet access to train commuters, but none of them combines broadband access, scalability, seamless handover and quality of service guarantees in one solution. This paper proposes a new architecture...

- Congestion Control: SCTP Vs TCP
- This paper characterizes an inefficiency in the current speciation of SCTP's congestion control, which degrades performance (more than necessary to be 'TCP-friendly') when there are multiple packet losses in a single window. It presents an SCTP variant, called New-Reno SCTP, which introduces three medications. First, a Fast Recovery mechanism, similar...

- Load Balancing Over Multipaths Using Bandwidth-Aware Source Scheduling
- This paper proposes an extension to SCTP featuring support for bandwidth-aware load balancing over multiple paths. Such extension may be useful to improve the throughput of data transfers when more than one path, spanning heterogeneous wireless networks, is available. In addition, it can provide reliability during horizontal and vertical handovers...

- Implement of FTP Application Using SCTP
- The transport layers were designed for the terminal communication among the applications that operate in different hosts. This is an attempt to simplify the application development by eliminating the application layer's dependency on network layers. Transport layers, which provides functions such as flow control, error solution, and secure transfer, has...

- Optimizing the ASC WAN: Evaluating Network Performance Tools for Comparing Transport Protocols
- The Advanced Simulation & Computing Wide Area Network ASC WAN, which is a high delay-bandwidth network connection between US Department of Energy National Laboratories, is constantly being examined and evaluated for efficiency. One of the current transport-layer protocols which is used, TCP, was developed for traffic demands which are different...

- Reliable Signaling System 7 (SS7) Transport Over Satellite Links
- Satellite communication channels allow operators to reach otherwise unreachable locations. This comes with the price of significant delays in the transmission channel. Legacy SS7 links may experience link failure, causing links to go up and down over a satellite link, a phenomenon usually referred to as link flap. SS7 OVER...

- Introduction to the Diameter Protocol in 3GPP Context
- Diameter is an AAA (Authentication, Authorization and Accounting) protocol for applications such as network access or IP mobility. The basic concept is to provide a base protocol that can be extended in order to provide AAA services to new access technologies. Diameter is intended to work in both local and...
