Abstract
The present invention switches a source of a streaming session between a primary server and its client, from the primary server to another server at arbitrary points during the progress of the streaming session. The switching of the source is accomplished through the use of a virtual socket capable of simultaneously phasing in a new streaming connection while phasing out an old streaming connection during a streaming session that preserves the temporal progress of the session. The virtual socket acts as a client-based intermediary between the client and one or more streaming servers, thus enabling a client application to establish a streaming connection with respect to content and not to the end-party, i.e., server.
