Abstract
A multi-layered network for transporting data comprises a first network layer that provides a first session topology, and a second network layer that provides a second session topology. The second network layer uses the first network layer to transport data. In one embodiment of the invention, the data sent by the second layer is real-time audio data, such as voice. Each session topology may be either peer-to-peer or client/server. The first and second layers may have different topologies and/or different session hosts. A deterministic algorithm is provided whereby a new session host is selected when the current host leaves the session.
