Abstract: PROBLEM TO BE SOLVED: To provide a method operating on an established first connection between a first endpoint device and a second endpoint device. SOLUTION: An example embodiment of the method comprises a decision step in which a decision is made in the first endpoint device whether to switch form the first connection to a second connection between the first endpoint device and the second endpoint device. Upon the decision being to switch, an information exchange step is carried out for exchanging connection information between the first endpoint device and the second endpoint device, enabling the establishment of the second connection. Furthermore, a setup step is carried out for establishing the second connection under use of the connection information. The invention further relates to a telecommunication endpoint device that provides selection between the two connections.

Abstract: A method, a system and a device for data communication between a sender and a plurality of recipients are provided to be used for interactive multimedia systems such as interactive television game shows. First, the sender transmits over a data network a first message. The first message causes a response message returned by one of the plurality of recipients to be delayed for a random period of time. Then, the sender broadcasts a second message asking the plurality of recipients for a response message. After having received the second message, each recipient initiates a response message. The response message is delayed for a random delay time. Thereafter, the response message is transmitted to the sender over the data network. Finally, the sender waits for a second period of time for response messages to arrive at the return address. A major advantage of the invention is a reduction of a peak load caused by the recipients' response messages.

Abstract: A plurality of protocol stacks are deployed. Each of the protocol stacks includes a plurality of composable protocol modules, and each of the composable protocol modules implements common interfaces. It is detected that a first given one of a plurality of clients wishes to connect to a publication-subscription engine and it is determined whether the first given one of the plurality of clients is to be connected in a secure manner. Responsive to determining that the first given one of the plurality of clients is to be connected in the secure manner, an encrypted instance of a first appropriate one of the plurality of protocol stacks is instantiated to effectuate the secure connection. The first given one of the plurality of clients is authenticated and authorized.
