Abstract

It is proposed to apply an integrated admission control scheme to both streaming flows and elastic flows. It is assumed that streaming flowpac kets are served with priority in network queues so that admission control ensures minimal delay for audio and video applications while preserving the throughput of document transfers. An implicit measurementbased implementation is proposed where admissibility is based on an estimation of the bandwidth a newelastic floww ould acquire. An analytical fluid flowmo del provides insight and guides the choice of admission thresholds. Detailed packet level simulations of TCP and UDP connections showthat the proposed algorithms work satisfactorily in the range of admission thresholds predicted by the fluid model.
