Allocation of channel capacity in multiservice networks

Abstract

Methods are described which enable the operator of a network such as an Internet protocol (IP) network to allocate ingress and egress channel capacity for the use by different services or for use by different service providers. The methods can prevent a service provider or a service from overusing network capacity. The methods also enable the network operator to temporarily allocate unused capacity if demand for a service exceeds previously allocated capacity. Further a method is described whereby capacity on a Voice over Internet protocol (VoIP) network is sold to service providers with guarantees for the number of available channels, where the channel capacity guarantees could be global, or by any type of subdivision. In addition to having a committed channel capacity, the service provider could be allowed to exceed the committed capacity whenever excess capacity is available on the network.
