Analysis and Modeling of World Wide Web Traffic by Ghaleb Abdulla Doctor of Philosophy in Computer Science and Applications Virginia Polytechnic Institute and State University, 1998 Professor Edward A. Fox, Chair This dissertation deals with monitoring, collecting, analyzing, and modeling of World Wide Web (WWW) traffic and client interactions. The rapid(More)
Congestion control plays an important role in the effective and stable operation of ATM networks. This paper first gives a historical overview of rate-based congestion control algorithms developed in the ATM Forum, showing how the current ATM Forum standard regarding the traffic management control methods is exploited, by these algorithm. Then, analytical(More)

We study routing methods in all–optical switching networks. In all–optical switching networks, the connection with more hops encounters more call blocking, and it is especially true in optical networks with no wavelength conversions. We therefore consider an alternate routing method with limited trunk reservation in which connections with more hops are(More)
An ATM network is expected to support a large number of bursty traffic sources and, therefore, it becomes critical to control network traffic in order to provide a desirable level of performance. One important realization for that purpose is admisson control, which decides to accept a new call or not dependent on current resource usage so that the network(More)
We investigate the performance of TCP under three representatives of packet scheduling algorithms at the router. Our main focus is to investigate how fair service can be provided for elastic applications sharing the link. Packet scheduling algorithms that we consider are FIFO (First In First Out), RED (Random Early Detection), and DRR (Deficit Round Robin).(More)
As the use of real-time multimedia applications increases, bandwidth available to TCP connections is oppressed by “greedy” UDP traffic and their performance extremely deteriorates. In order that both TCP and UDP sessions fairly co-exist in the Internet, UDP sessions should properly react against congestion as TCP. In this work, we implement a “TCP-friendly”(More)
