Bandwidth adjustments using online packet-level measurements
George Kesidis · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1999
Because of the large statistical complexity of the traffic in communication networks, connection admission controls (CAC) often use only crude initial estimates of the required bandwidth for variable bit-rate connections. This is one reason why on-line measurements of the existing network traffic have been proposed. The well-known effective bandwidth formulation or recent worst case bounds could be used by CAC. On-line methods of estimating the received quality-of-serve of connections from `feasible statistics' could be used to modify the bandwidth allotment of such connections. Such bandwidth modifications occur at a time- scale between those of the packet level and connection (i.e., CAC) level.
