Simulation of the error control procedures in the Xpress Transport Protocol
… media, the demand for a more efficient transport layer protocol is increasing. Many research activities have been devoted to this area. The Xpress Transport Protocol (XTP) is one such example. XTP was designed to fix some deficiencies in the Transmission Control Protocol (TCP), and to …

The Design and Simulation of a Transport Protocol for Interactive Network Applications
… network, which uses the Transmission Control Protocol (TCP) for guaranteed data delivery. In addition to providing a reliable data transport layer, TCP aids the stability of a large scale internetwork through congestion detection and avoidance algorithms. Since TCP's inception in 1981, both …

Transport layer protocol design over flow-switched data networks
In this work, we explore transport layer protocol design for an optical flow-switched network. The objective of the protocol design is to guarantee the reliable delivery of data files over an all-optical end-to- end flow-switched network which is modeled as a burst-error channel. We observe that …

A network interface for a distributed system on 110 Mbps optical fibre AMNET
… data transfer between nodes. A very reliable transport protocol with large sliding window size is proposed here. This transport protocol has the advantage of taking care of any message loss and minimizing the acknowledgement message returned to the sender. The network interface equipment is …

SCTP Performance Improvement Based on Adaptive Retransmission Time-Out Adjustment
The Stream Control Transmission Protocol (SCTP) was designed to combat certain types of faults which commonly occur in IP networks The algorithm used in SCTP that estimates the Round Trip Time (RTT) between nodes are critical to the effectiveness of the transport protocol. This work focuses in the …

Experimental Evaluation of Convergence Layers in Delay Tolerant Networks
Traditional Internet protocols like TCP/IP and UDP/IP are not designed to perform efficiently in Delay Tolerant Networks (DTN) environments that operate in environments with high delays, significant losses, and intermittent connectivity. DTN uses the Bundle Protocol (BP) in the Bundle layer for …

Hop-by-Hop Transport Control for Multi-Hop Wireless Networks
… This thesis explores the design of a hop-by-hop transport protocol (HxH). By allowing intermediate nodes to actively participate, the protocol can respond more quickly to changing network conditions and exploit the unique characteristics of wireless networks. Results indicate that hop-by-hop …

Application Aware Multicasting in VPLS Networks.
… in a Point-to-Multipoint VPLS network using Multiprotocol Label Switching (MPLS) as a transport protocol. MPLS is a Layer 2.5 transport protocol that encapsulates and labels frames from their sources to their destinations. MPLS uses labels to identify the frame destination and in so doing reduces …

Optimising data centre operation by removing the transport bottleneck
… scale” computers. Data centres rely on TCP, a transport protocol that was originally designed for use in the Internet. Like other such protocols, TCP has been optimised to maximise throughput, usually by filling up queues at the bottleneck. However, for most applications within a data centre …

ASAP: a low-latency transport layer
… establishment delay in the underlying network protocols, such as Domain Name System (DNS) and Transmission Control Protocol (TCP). In this work, we introduce ASAP, a new naming and transport protocol that significantly reduces latency by shortcutting DNS requests and eliminating TCP’s three-way …

Analysis of bandwidth attacks in a bittorrent swarm
… Bram Cohen developed a new Peer-to-Peer protocol called BitTorrent. The main principle behind BitTorrent is an incentive mechanism, called a choking algorithm, which rewards peers that share. Currently, BitTorrent is one of the most widely used protocols on the Internet. Therefore, it is …

Seamless handover among heterogeneous mobile networks using stream control transmission protocol (SCTP)
The Stream Control Transport Protocol (SCTP) is being adopted for general transport by IETF. SCTP supports multi-homing and allows endpoints to use multiple heterogeneous links in an association. An enhancement known as dynamic address reconfiguration (ASCONF) defines procedures to gracefully add …

A Transport Layer Approach to Host Mobility
… in the link or network layer. In comparison, the transport layer has access to end-to-end information not available at lower layers. Coupled with inverse multiplexing techniques and error classification algorithms, such information can be used to achieve a significant improvement in data …

User Datagram Protocol with Congestion Control
… disseminating information. TCP and UDP are the transport layer protocols responsible for transit of nearly all Internet communications. Due to the growth of real-time audio and video applications, UDP is being used more frequently as a transport protocol. As UDP traffic increases potential …

An integrated transport solution to big data movement in high-performance networks
… data transfer performance largely depends on the transport protocol being used on the end hosts. The high-speed network path with reserved bandwidth in High-performance Networks has shifted the data transfer bottleneck from network segments in traditional IP networks to end hosts, which most …

Effects of diversity routing on TCP performance in networks with stochastic channels
Transmission Control Protocol (TCP) is a widely used transport protocol in today's multimedia applications. TCP was originally designed for wired networks, and its performance is highly degraded in networks with stochastically variable links, such as satellite and wireless networks. One significant …

Protocol design for scalable and reliable group rekeying
… appears in vi RFC 2627. The scalability of rekey transport, however, was not addressed. The objective of this dissertation is to design a scalable and reliable rekey transport protocol and evaluate its performance. Rekey transport differs from data transport because rekey messages require …
