Patent ID: 8713310

Claim:
A method for transmitting payload data that implement at least one real-time application between at least one first communication device and at least one second communication device, the at least one first communication device comprising a first communication device and the at least one second communication device comprising a second communication device, wherein the payload data will be transmitted as data packets during a communication connection, the data packets comprising first data packets and second data packets, the method comprising: at a first time period, during the transmission of the data packets between the first and second communication devices, the first communication device embedding at least one first data packet of the first data packets with first authentication information enabling authentication of the first communication device; the first communication device transmitting the first data packets to the second communication device; the second communication device receiving the first data packets and extracting the first authentication information embedded within the at least one first data packet of the first data packets; upon a determination that the first authentication information authenticates the first communication device, the second communication device maintaining the communication connection and forwarding the first data packets for appropriate processing; at a second time period that is after the first time period, and during the transmission of data packets between the first and second communication devices, the first communication device embedding at least one second data packet of the second data packets with first authentication information enabling authentication of the first communication device; the second communication device receiving the second data packets an amount of time after the receipt of the first data packets and forwarding of the first data packets; the second communication device extracting the first authentication information embedded within the at least one second data packet of the second data packets; and upon a determination that the first authentication information authenticates the first communication device, the second communication device maintaining the communication connection and forwarding the second data packets for appropriate processing.
