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 …

Multipath transport for virtual private networks
… Private Networks (VPNs) are designed to use the Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) to establish secure communication tunnels over public Internet. Multipath TCP (MPTCP) extends TCP to allow data to be delivered over multiple network paths simultaneously. This …

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 …

Development and Evaluation of the Ethernet Interface(s) for the Monitoring and Control System of a New Beamforming Radio Telescope
… are formed into beams. The Monitoring and Control System (MCS), a subsystem of each LWA station, controls the station's subsystems and also monitors their status. This thesis addresses the interface-related features of MCS. The physical interface of the MCS with each subsystem is a Gigabit …

Enhancing TCP delivery over wireless networks
… communication. Based on the idea of simplicity, Transmission Control Protocol (TCP) has been used widely over wired network. When network applications take place using wireless link, TCP is still useful because partial wired connection might be necessary. Although wired and wireless communication …

Simulation of the error control procedures in the Xpress Transport Protocol
… 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 provide a highly …

Burst TCP: an approach for benefiting mice flows
The Transmission Control Protocol (TCP) is responsible for supplying reliable data transport service on the TCP/IP stack and for carrying most than 90% of all Internet traffic. In addition, the stability and efficiency of the actual TCP congestion control mechanisms have been extensively studied …

Mitigating Network-Based Denial-of-Service Attacks with Client Puzzles
… in network security. Recently, client puzzle protocols have received attention as a method for combating DoS and DDoS attacks. In a client puzzle protocol, the client is forced to solve a cryptographic puzzle before it can request any operation from a remote server or host. This thesis …

Multipath "Fresnel Zone" Routing for Wireless Ad Hoc Networks
… and their interaction with transport layer protocols has not been thoroughly addressed in the literature. In this work, we propose the multipath “Fresnel zone” routing (FZR) algorithm for wireless ad hoc networks. FZR constructs multiple parallel paths from source to destination based on the …

The Design and Simulation of a Transport Protocol for Interactive Network Applications
… currently an IP datagram 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 …

Learning-Based Quality of Service Prediction in Cellular Vehicle Communication
… which may lead to a takeover maneuver, in which control is returned back to the driver. Since such a handover takes time, prediction is necessary to forecast the network quality for the next few seconds. Prediction of QoS parameters, especially in terms of Throughput (TP) and Latency (LA), is …

Device-type Profiling using Packet Inter-Arrival Time for Network Access Control
Network Access Control (NAC) systems are technologies and defined policies typically established to control the access of devices attempting to connect to enterprise networks. However, NAC limitations have led to security threats that can lead to illegal and unauthorised access to networks as well …

An investigation to cybersecurity countermeasures for global internet infrastructure.
… ASes are globally connected via the inter-domain protocol that is Border Gateway Protocol (BGP). BGP was designed to be scalable to handle the massive Internet traffic; however, it has been studied for improvements for its lack of security. Furthermore, it relies on Transmission Control Protocol …

Performance modeling of congestion control and resource allocation under heterogeneous network traffic. Modeling and analysis of active queue management mechanism in the presence of poisson and bursty traffic arrival processes.
… and congestion bottlenecks. Efficient congestion control is fundamental to ensure the Internet reliability, satisfy the specified Quality-of-Service (QoS) constraints and achieve desirable performance in response to varying application scenarios. Active Queue Management (AQM) is a promising scheme …

Improving TCP performance over heterogeneous networks : The investigation and design of End to End techniques for improving TCP performance for transmission errors over heterogeneous data networks.
Transmission Control Protocol (TCP) is considered one of the most important protocols in the Internet. An important mechanism in TCP is the congestion control mechanism which controls TCP sending rate and makes TCP react to congestion signals. Nowadays in heterogeneous networks, TCP may work in …

Design and implementation of split TCP in the Linux kernel
The Transmission Control Protocol (TCP) was designed for reliable communication between computers over networks of unpredictable quality. It has admirably succeeded in satisfying the needs of the growing internet. Yet, there are combinations of network problems too bad even for TCP. In particular, …
