Adaptive resource negotiation based control for real time applications

In this paper, we focus on providing quality-of-service (QoS) control in te rms of packet loss and delay for interactive real-time applications. We pro pose a new scheme to find the optimal values of token bucket parameters, to ken generation rate r and token bucket size b, from the observed real-time traffic. This can be adjusted based on the user's QoS requirement and the d ifferent classes of real-time applications. Based on these optimal token bu cket parameters, we introduce an adaptive resource negotiation control sche me. Our proposed admission control scheme offers the re-negotiation feature in the resource reservation process allowing higher admission ratios and h igher resource utilization to be achieved.
