The Internet Protocol Stack provides a set of transport layer protocols. There are two dominant types of transport layer protocol used in the Internet: UDP (User Datagram Protocol) and TCP (Transmission Control Protocol). The transport layer provides end-to-end information transfer across a network with the quality of service needed by the application. In this paper, we provide a performance comparison...
There has been considerable research into the performance of the enhanced IEEE 802.11e standard in recent years. Majority of the performance analysis has been based on simulations and analytical models, with little testing done in a real-world environment. We investigate the behaviors of the enhanced distributed channel access (EDCA) and legacy distributed coordination function (DCF) based on a testbed...
Multimedia applications have been the key driving force in converging fixed, mobile and IP networks. A major hurdle in the realisation of this convergence is obtaining Quality of Service from a heterogeneous, best-effort service network. Interactive voice requires strict bounds on delay, jitter and packet losses, video adds significant bandwidth requirements to the network, while Internet only makes...
