Constant bandwidth vs. proportional share resource allocation

Due to the success of new multimedia technologies, there is a great interest in providing a resource allocation strategy suitable for multimedia applications. Many solutions proposed in the literature are based on proportional share resource allocation, such as WFQ, WF² 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 advantages and drawbacks of both techniques
