LEVERAGING INTERNET PROTOCOL (IP) NETWORKS TO TRANSPORT MULTI-RATE SERIAL DATA STREAMSHeath, Doug; Polluconi, Marty; Samad, Flora; RT Logic Incorporated (International Foundation for Telemetering, 2006-10)As the rates and numbers of serial telemetry data streams increase, the cost of timely, efficient and robust distribution of those streams increases faster. Without alternatives to traditional pointto- point serial distribution, the complexity of the infrastructure will soon overwhelm potential benefits of the increased stream counts and rates. Utilization of multiplexing algorithms in Field- Programmable Gate Arrays (FPGA), coupled with universally available Internet Protocol (IP) switching technology, provides a low-latency, time-data correlated multi-stream distribution solution. This implementation has yielded zero error IP transport and regeneration of multiple serial streams, maintaining stream to stream skew of less than 10 nsec, with end-to-end latency contribution of less than 15 msec. Adoption of this technique as a drop-in solution can greatly reduce the costs and complexities of maintaining pace with the changing serial telemetry community.
