Abstract
An ongoing project of the Highly Dependable Systems Research Programme
(PHDS) at the University of the Witwatersrand is the development of a
dependable autonomous decentralised system using readily available
hardware and software components. The experimental system consists of
Unix stations connected by ethernet. Real-time communication protocols
and fault tolerant protocols have implemented as a fault-tolerant
real-time environment to support various applications. Inspired from
South African industry's requirement, the Internet service redirector
is chosen as the application of the PHDS system. A firewall application
has been implemented on the virtual redirector. Current work on this
project includes: introduction of mobile agent technology into the
system and implementation of a testbed to evaluate the availability and
performance of the system.
