As it is proven by practice, load balancing techniques are the only
tool that network service provider have, in order to support and
handle scalable network load. This paper presents PEGASUS, a novel
framework that provides load balancing in network services transparently,
using a competitive scheduling algorithm.
PEGASUS is designed upon the inetd superserver, thus providing a easy to
configure, yet efficient infrastructure. Our proposed architecture is based
on well known user space tools. The prototype implementation is using inetd
as the basis application. Using inetd we provide a simple scheme for service
categorization, using tcp/ip network ports. The scheduling algorithm that our
system proposes is competitive. The paper concludes with a comparison of
PEGASUS and other well known similar infrastructures.
