A paper on fast circuit switching, which was referred to as "dynamic channel switching," was originally published in IP Applications and Services 2003: A Comprehensive Report by the International Engineering Consortium (copyright 2002). This paper describes a networking approach that combines the advantages of circuit switching and packet switching in an integrated communications network. Here is a link to the paper on: convergence based on fast circuit switching.
With the proposed fast circuit switching approach, control signals are separated from the data and are transmitted separately in a common control channel. Control and signaling operation can be viewed as a logical extension of Generalized MPLS (GMPLS). A variable number of data channels are dynamically assigned to each connection through the network. Channels are quickly switched in to accommodate the data flow through a connection and switched out when they are no longer needed. With this dynamic channel switching approach, a continuous data stream is not altered as it transits the network, and data channels are efficiently utilized even if the data source is bursty. The proposed approach is compatible with legacy networks and can provide a mechanism for convergence of circuit switching and packet switching. Most of the benefits of the proposed approach can be achieved if only network and server equipment, but not client equipment, is upgraded to support dynamic channel
switching.
