Patent ID: 7571245

Claim:
Method for dynamically externalizing service delivery with a streaming system in a data transmission system in which at least one user computer is connected to an Internet protocol (IP) transport network to transmit requests to and receive data from a plurality of servers through a switch layer and to receive stream delivery from at least one of the servers in charge of handling at least one user context associated with the at least one user, the method comprising: forwarding the at least one user context to an external service infrastructure partner (SIP) device when the streaming system is triggered by a first event, wherein the first event is a manual action from an operator or an automatic action based on technical or business rules; reconfiguring the switch layer when the at least one user context is received by the external SIP to allow user reconnection requests to be rerouted to the SIP; stopping the stream delivery for the at least one user computer; and restarting the stream delivery by the SIP upon receiving a reconnection request from the at least one user computer.
