A zero-added-jitter protocol for transmission of datagrams over packet-switched networks between two or more connected microprocessor devices with negligible packet delay variation and negative acknowledgment datagram recovery. A method for the analysis and preservation of the instantaneous bitrate and packet spacing provides for the output of the datagrams to a network facing provider edge device matching in timing and inter-packet spacing, that which was originally received, along with a pre-configured time-delay for error correction. Additional embodiments provide duplication of path for reduction of re-requests; the splitting of path for faster transport between transmitter and receiver; encryption for more secure transport between transmitter and receiver; compression for more efficient transport between transmitter and receiver; and encryption and compression, for more secure, efficient transport between transmitter and receiver.
