Patent ID: 7672306

Claim:
A method for sending secure reliable point to multi-point transmissions, the method comprising: establishing an overlaying protocol being interpretable at each end of potential links of a point to multi-point transmission; and sending feedback data from one of a plurality of multiple end nodes (MEN) being one end of the point to multi-point transmission to a sender node (SN) being another end of the point to multi-point transmission, wherein the feedback data is sent in accordance with the established overlaying protocol, whereby the feedback data provides the SN with information for improving reliability, wherein the SN encapsulates messages to the MEN comprising encapsulated DATA_PACKETS and MESSAGES based on the protocol, wherein the DATA_PACKETS contain ACCESS_SYNCH_CODE, PACKET_TYPE, CMD (command), RESERVED, PACKET SIZE, PACKET_NUMBER (sequence number), PACKET FORMAT, DECRYPT_Y_N, QUIET (stop requesting re-transmission for x time), and PAYLOAD.
