ABSTRACT:
A system and method for providing real-time, dynamic switching between first and second service providers each capable of providing a service for users over a communications network. The method includes steps of: establishing switching criterion for deciding when to switch service provision between the first service provider and second service provider; maintaining state information associated with a user's use of the service provided by a first service provider; switching between the first and second service provided over the communications network based on satisfaction of the switching criterion; and, migrating any state information maintained up to the time of switching to the second service. Preferably, the dynamic switching occurs in a manner substantially transparent to the user.
