Multimedia switching system
First Claim
1. A communications network arranged to provide multimedia switched services comprising a set of minichannel media components, wherein said set of minichannel media components is encapsulated in an ATM virtual circuit and is switched as an entity so as to provide connection records for usage based tariffing purposes, and wherein the minichannel components carry IP protocols and are switched using IP cut-through routing applied at the adaptation switching layer.

Abstract
A communications network arranged to provide multimedia switched services comprising a set of media components. The set of media components including IP traffic is encapsulated in an ATM virtual circuit and is switched as an entity using a robust signalling system so that the resultant connection records can then be employed for usage based tariffing purposes. This overcomes the problem of establishing billing records for connectionless traffic carried over a connection oriented network.
