Abstract
A method for reliably communicating unreliable protocol packets by encapsulating one or more unreliable protocol packets in a packet constructed according to a predefined format. The method further employs an acknowledgement mechanism whereby a receiver of packets acknowledges reception by responding with a packet containing information pertaining to received packets. A sender retransmits packets for which no acknowledgement was received within a predefined period of time.
