Abstract
A control process controls transmission of digitally encoded messages (DEMs) over a data communications network to allow real-time performance. The control process establishes a communication path which DEMs are sent. The control process can operate according to any data communications protocol, including the protocol native to the communicating device. The control process can establish communication paths based upon least-cost routing determinations. When there is insufficient bandwidth or excessive latency, the control process can choose a secondary path over which to transmit a DEM.
