Summary:The authors show the existence of effective bandwidths for
multiclass Markov fluids and other types of sources that are used to
model ATM traffic. More precisely, it is shown that when such sources
share a buffer with deterministic service rate, a constraint on the tail
of the buffer occupancy distribution is a linear constraint on the
number of sources. That is, for a small loss probability one can assume
that each source transmits at a fixed rate called its effective
bandwidth. When traffic parameters are known, effective bandwidths can
be calculated and may be used to obtain a circuit-switched style call
acceptance and routing algorithm for ATM networks. The important feature
of the effective bandwidth of a source is that it is a characteristic of
that source and the acceptable loss probability only. Thus, the
effective bandwidth of a source does not depend on the number of sources
sharing the buffer or the model parameters of other types of sources
sharing the buffer
