The most common measurement for network speed is data rate, counted as the number of computer bits that travel over the connection in one second. Modern computer networks support data rates of thousands, millions, or billions of bits per second. Speed tests also often include a separate measurement for network delay, sometimes called ping time.

Consistent sampling for network traffic measurement
InactiveUS6873600B1Reduce ambiguityIncrease choiceError preventionFrequency-division multiplex detailsHash functionNetwork measurement
Traffic measurement should make it possible to obtain the spatial flow of traffic through the domain, i.e., the paths or trajectories followed by packets between any ingress and egress point of the domain. A method of sampling packet trajectories in a packet switching network allows the direct inference of traffic flows through a measurement domain by observing the trajectories of a subset of all packets traversing the network. A method which assumes that the measurement domain does not change comprises the steps of selecting packets for sampling in accordance with a sampling function of the packet content and generating a practically unique label for each sampled packet. The method does not rely on routing state, its implementation cost is small, and the measurement reporting traffic is modest and can be controlled precisely. Using the same hash function will yield the same sample set of packets in the entire domain, and enables us to reconstruct packet trajectories. An alternate embodiment which assumes no constraints and that the measurement domain may change comprises the steps of applying a sampling function and altering an invariant bit position as a signaling flag in each packet selected for sampling.

When performing load balancing in a wireless extended self-organizing network (extended SON), network health status is monitored by collecting network measurement data and identifying network nodes that require policy adjustment. Based on the network measurement data, network and / or user policies are automatically adjusted and policy updates are disseminated by a policy and charging rule function module to a packet gateway (PGW) as well as to one or more non-PGW network nodes (e.g., base stations, mobility management entity (MME) nodes, radio network controller (RNC) nodes, and the like). The automated policy updates are locally enforced at the nodes that receive the updates, rather than solely at the PGW node.

Measuring speech quality over a communications network
InactiveUS20020193999A1Reduction of informationSpeech analysisSupervisory/monitoring/testing arrangementsNetwork measurementPESQ
When the PESQ and similar algorithms are used to measure speech quality, a particular voice call is set up to transmit only test voice signals over a communications network. This enables the test voice signals to be easily identified and provides a means of determining the amount of degradation that occurs as a result of transmission of the test voice signals. However, one problem is that in packet switched networks the transmission characteristics change with time. Thus the estimated MOS score obtained cannot be assumed to give an accurate speech quality measure for a voice call later made between the same two points. By adding test voice information to an ongoing voice call and transmitting that test voice information integrally with the ongoing voice call these problems are addressed. The test voice information is sent in packets during silent periods in the voice call such that the voice call is not affected by the test voice information. An identifier is used to identify or label the packets comprising test voice information. In the case that real-time transport protocol is used, the identifier is preferably a payload type value.
