Abstract:
1. A network supervisory control and data acquisition (SCADA) system for dynamically and continuously (i) discovering at least one router in a communication path between a communication server and at least one remote device being monitored and controlled with the supervisory control and data acquisition system, (ii) calculating latencies incurred by each hop of at least one tracer packet deployed by the communication server, to determine bandwidth restrictions, the supervisory control and data acquisition system comprising: a. the at least one remote device with a destination internet protocol address; b. the communication server with an origination internet protocol address comprising: c. the at least one tracer packet deployable from the communication server, the at least one tracer packet comprising: d. the at least one router in the communication path between the at least one remote device and the communication server, each router comprising: the at least one tracer packet is deployed by the communication server making an initial hop to discover a first router which decrements the time to live value by one, and then the at least one tracer packet makes additional hops to discover additional routers towards the destination internet protocol address until the time to live value of the at least one tracer packet is zero, and the communication server calculates latencies incurred by each hop to obtain an indication of bandwidth restrictions for the supervisory control and data acquisition system.
