Abstract:
1. A method for communicating between a first and a second machine, the method comprising: providing by the first machine, a reliability delivery layer (RDL) interface to a User Datagram Protocol (UDP) layer on the first machine; establishing by the first machine a UDP connection with the second machine; and establishing by the first machine, a transport layer security over the RDL interface to the UDP layer on the first machine; wherein the transport layer security is incompatible with the UDP and is separated from the RDL; the RDL is configured to make the UDP appear to be compatible with the transport layer security without modification to the transport layer security or to the UDP; and the RDL layer comprises a header including a checksum field to emulate Transmission Control Protocol (TCP) checksum used for data protection, a sequence number field and an acknowledgement field to emulate TCP data loss detection and recovery, and a flag field to facilitate TCP like connection oriented behavior management.
