Abstract:
1. A method of operating a communication system to determine latent applications in a communication network, the method comprising: in a transmitter, transferring a first packet comprising a first test code to a network node; in the network node, receiving the first packet, and in response to the first test code, time stamping the first packet resulting in a first timed stamped packet, and transferring the first time stamped packet; in a receiver, receiving the first time stamped packet and transferring the first time stamped packet to a test server; in the test server, determining a node latency of the network node based on the first time stamped packet; if the node latency is greater than a first threshold, then in the transmitter, transferring a second packet comprising a second test code to the network node; in the network node, receiving the second packet, and in response to the second test code, time stamping the second packet resulting in a second time stamped packet, and transferring the second time stamped packet; in the receiver, receiving the second time stamped packet, and transferring the second time stamped packet to the test server; in the test server, determining an application latency of an application based on the second time stamped packet; if the application latency is greater than a second threshold, then receiving application data associated with the application.
