Optimal filtering in traffic estimation for bandwidth brokers
In this paper we present a method for an on-line
traffic optimal estimation on a communication link. The
proposed filtering procedure is based on a traffic model
constituted of a birth and death process, elaborates the current
noisy measurements from the link and minimizes the estimate
error conditional variance. Performance of the method is tested
by considering both simulated and real data. This result is of
interest with reference to a possible procedure for bandwidth
allocation in the framework of Bandwidth Brokers. The
bandwidth allocation is necessary to provide Quality of Service
guarantees to users and requires, as a preliminary step, the on
line traffic estimation
