ABSTRACT
The goal of QoS routing is to find a loopless path through a
network that can satisfy a given set of constraints on parame-
ters such as bandwidth, delay and cost. QoS routing algorithms
can be classified into three categories. They are Source routing,
Distributed routing and Hierarchical routing. In this paper we
propose a distributed QoS routing algorithm that gives high call
admission rates in a congested network for constraints on met-
rics like bandwidth, buffer, and CPU usage with a low message
complexity.
1. INTRODUCTION
Resource reservation is a necessity for providing guar-
anteed end-to-end performance for multimedia applications.
However in the present Internet setup, resource reservation
is not supported. Also, the data packets of these applications
