Abstract
Due to the success of new multimedia technologies, there
is a great interest for providing a resource allocation strat­
egy suitable for multimedia applications. Many solutions
proposed in literature are based on proportional share re­
source allocation, such as WFQ, WF 2 Q, EEVDF, or SFQ.
In a previous paper, we showed how to perform resource
reservation according to a Constant Bandwidth allocation.
In this paper we compare Proportional Share and Constant
Bandwidth resource allocation strategies, by showing ad­
vantages and drawbacks of both techniques.
1. Introduction
There exists a large class of applications that require real­
time computation in order to be effective. An interesting ex­
ample is given by multimedia systems, which manage Con­
