Abstract
A method that alleviates congestion problems in prior art networks by insuring that selected classes of calls have a reserved capacity, thus insuring a capability to service at least the selected level of traffic. In an illustrated embodiment, a selected capacity is reserved for voice calls, in contrast to data calls. When a connection request is made and there is unoccupied capacity, a voice call is always serviced, but a data call is serviced only if the number of established data connections is less than capacity of the path required for establishing a connection for the request, minus the capacity reserved for voice call.
