Design and implementation of measurement-based resource allocation schemes within the realtime traffic flow measurement architecture

The concept of effective bandwidth can be utilized to estimate the amount of bandwidth that should be allocated to a source in order to meet a QoS requirement. Several different effective bandwidth estimators have been defined in the literature; however it is necessary to ensure that these estimators are practically implementable and feasible in realistic network environments. This necessity serves as our motivation to implement several estimators in a realistic network in order to evaluate the use of online measurement-based resource allocation schemes. In this paper, we describe our implementation of three resource allocation schemes within the realtime traffic flow measurement architecture. We compare our results of emulation to previous simulation results in order to compare the accuracy and performance of the schemes. Finally, we demonstrate that these schemes are feasible to be implemented in network hardware to be utilized in self-sizing high-speed networks.
