Abstract: The correlating network transactions techniques include a method, an apparatus, and/or a computer program product. In some embodiments of these techniques, the method includes receiving, at a first monitor server, a first plurality of network transmissions from a first plurality of communication networks and correlating, at the first monitor server, the first plurality of network transmissions based on information associated with the first plurality of network transmissions to form a first correlated network transaction.

Abstract: A packet transmission diagnostic system transmits diagnostic packets during a communications session in which data packets are transmitted between a source and destination. The diagnostic packets elicit responses from routers along a path between the source and destination. The elicited responses, in the form of packets, are used by the diagnostic system to produce one or more packet-delivery metrics for one or more of the routers along a packet transmission path between the source and destination.

Abstract: A method of measuring jitter of a packet flow includes identifying the data packet flow at each of a first and second network locations by analyzing the data fields of each of the packets in the flow. The method associates a transmit time code with each packet transmitted from the first location, and associates a receive time code with each packet received at the second location. The method calculates inter-arrival times for consecutive pairs of packets by (i) subtracting the transmit time code of the first packet from the transmit time code of the second packet, (ii) subtracting the receive time code associated with the first packet from the receive time code associated with the second packet, and (iii) subtracting the results. The method includes calculating a jitter value as a smoothed version of two or more inter-arrival times, smoothed over a predetermined number of pairs of consecutive packets.
