1. A method for providing optimal transaction routing of data packets through a network on a plurality of logical pipes, comprising:

  • assigning each data packet to one of the plurality of logical pipes, each logical pipe having an assigned numerical service level;

    associating a numerical priority-usage level to each of the assigned data packets;

    establishing a numerical threshold return-time-out (RTO) for each logical pipe;

    transmitting data packets from one of the logical pipes and evaluating a running estimate of round trip times (RTT) for the transmitted data packets from the logical pipe being serviced; and

    transitioning to a subsequent logical pipe in a round robin manner once a combination of numerical priority-usage levels for the delivered data packets has at least equaled the numerical service level for the logical pipe being serviced, or once a current estimate of the RTT for the delivered packets has at least equaled the threshold RTO for the logical pipe being serviced.
