Warren's Ph.D Thesis
Welcome to the on-line version of my Ph.D thesis. Here is the title and
abstract of the thesis:
A Rate-Based Congestion Control for
Connectionless Packet-Switched Networks
The control of congestion in connectionless packet-switched wide-area
networks is a major problem, especially in such networks as the Internet,
which is experiencing an exponential growth in users and network traffic.
This thesis outlines a rate-based framework for congestion control in
these networks, examines the requirements of the framework, and describes
a number of control mechanisms which meet the framework's requirements.
The effectiveness of the framework in combatting congestion is
demonstrated by a series of simulation experiments, which also
compare the framework against traditional end-to-end congestion control
mechanisms. Experimental results indicate that rate-based congestion control
provides excellent congestion control. Moreover, a rate-based framework
achieves much better congestion control in these networks than traditional

There, you will find the following:
wkt_real.tar.gz: A full distribution of REAL 4.0, with
modifications as described in Chapter8.
Note that the modifications have only been verified
on machines running SunOS 3.5 and FreeBSD 2.x.
wkt_scenarios.tar.gz: The input scenario files which
were discussed in Chapter 9, and listed
in Appendix E. Please note the rider
at the beginning of Appendix E.
random_scenarios.tar.gz: The 500 randomly-generated scenario files
which were described in Chapter 10.
param_changes.tar.gz: A set of changes which were made to the
500 randomly-generated scenario files in order to obtain the
parameter results described in Chapter 11.
trump_spin.tar.gz: The input files to the Spin protocol verification
suite which were used to verify the TRUMP protocol, described
in Appendix B.
