The effective bandwidth is a descriptor in the context of stochastic models for statistical sharing of resources. One of the most interesting properties of effective bandwidth is that it does not change when passing a network node under many sources limiting regime (infinitely many sources). This is referred as the "Invariance property" of effective bandwidth. Numerical simulations have suggested that in some cases, the "Invariance property" of effective bandwidths holds already for a surprisingly small number of competing flows even in the presence of aggressive TCP traffic.
