Title: DATA TRANSMISSION BY MEANS OF AN UNRELIABLE AND A RELIABLE TRANSPORT MECHANISM
Abstract:
A method and mechanism is described for reliably transmitting messages over an unreliable transport mechanism. A (180) sender transmits a first message over an unreliable transport mechanism (150) to a receiver (190), and a second message that identifies the first is transported over a reliable transport mechanism (160) to the receiver. When the receiver (190) receives the second message, the receiver (190) determines whether it has received the first message. If not, the receiver (190) requests retransmission of the first message.
