Abstract
An asynchronous transfer mode (ATM) switch (12) in an ATM network is provided with a connection admission control function which is periodically modified in a predetermined manner in dependence on a measurement of bandwidth utilization of the ATM switch (12) over an interval encompassing a number of call connections. The ATM switch (12) implements an effective bandwidth type connection admission control function which bestows an amount of bandwidth to each of a number of connection types which are supported. One or more higher layer connection admission control functions are provided which are responsive to traffic fluctuations to modify effective bandwidths for connection types stored by the ATM switch in a predetermined manner.
