Abstract: A quality of service monitor adapted to measure a separate value for a quality of service for each of a plurality of monitoring intervals, where each monitoring interval is shorter than the total time duration of a network communications session and longer than the time duration of one data packet in the plurality of packets included in the session. A processor searches for the one monitoring interval with the poorest quality of service value and reports the quality of service for the session as the poorest quality of service for the one monitoring interval.

Abstract: Measuring a quality of service in an Internet protocol network includes forming no more than one echo request packet in an originating device; transmitting the echo request packet to a destination device; swapping the source and destination addresses in the received echo request packet to form an echo reply packet without allocating memory for a new packet; receiving at the originating system the echo request packet repurposed as the echo reply packet; comparing a DSCP value in the echo request packet to a DSCP value in the echo reply packet; and when the DSCP values from the two packets are the same, asserting a prediction that the network will deliver a preferred quality of service for a streaming message service.

Abstract: Method creates Real-Time Estimates (RTE) of network parameters for responsive resources of a network management zone (NMZ) by sending requests in a management protocol and uses those real-time estimates to present a resource map of the NMZ, possibly altering a responsive resource, possibly posting a service schedule request. The invention includes implementation mechanisms and installation packages. The RTE of network parameter is a product of the process. Constructing a quality of service measure from RTE of at least two network parameters. Quality of service measure as a product of the process. The quality of service measure may include or be the Mean Opinion Score.

Abstract: A network quality control system includes a user control console to probe, calculate, and display the quality of an enterprise's network connections to remote SNMP managed devices supporting real-time services like VoIP. Traceroute-like messages are sent to each remote SNMP managed device to report on the path, and hop latency, jitter, and packet losses. MOS scores are computed to indicate performance with a variety of available codec's. Empty test packets used simply to probe network quality are not used. Instead, SNMP messages that carry valuable information or commands for other purposes are gleaned of timing information so the MOS quality scores can be calculated in background.
