Report of a network measurement. The full name of the network characteristic being measured. The hosts and mnetworks that are being tested. What test was run, and how it was run, in order to collect the measurement. Time that the measurement started, as a number of seconds since the Unix epoch 1/1/1970. If the endTime element is not present, this element could also be construed as the time the measurement 'was made', which may in reality be at the end of the test (!). Time that the measurement ended, as a number of seconds since the Unix epoch 1/1/1970. This time should be greater than or equal to the startTime. A measurement of this network characteristic. See http://dsd.lbl.gov/NMWG/docs/measurements.pdf Common elements for all result sub-types Result of performing a network test. Subclasses will be named for the particular type of result. If no timestamps are present, then use those provided for the enclosing resultSet. These units apply to both the "rawData" and "summaryData" sub-elements, unless these elements have a different value for their units attribute. Statistical summary Count of measurements Minimum measured value Maximum value Median Mean Standard deviation Network measurement tool Name of the tool Parameters that affect how a tool performs its measurement Parameters for tests that run over IP, including TCP/IP and UDP over IP. The duration of the test(?) Size of packets sent on network Number of packets sent on network What algorithm is used to space packets (poisson or periodic) Time between test packets, in seconds (for periodic tests) IP version (this information is also available as an attribute of the IPAddress, do we need it both places?) Type of service (IP precedence) differentiated services code point IP v6 option for QoS The threshold used to distinguish between a large finite delay and loss Amount of test traffic Are bytes moving memory to memory or disk to disk? Size of TCP buffers used Reno, Vegas, HSTCP, ScalableTCP, etc Number of parallel streams Some details about a host system. Description of a host operating system A network interface on a host This repeats the information already contained in the parent type NetworkPath. In the XML instance, those elements may be referenced here to avoid duplication. Path between a network source and destination node A network node A network path between exactly two hosts. Abstract network address Internet Protocol address Internet Protocol version (4 or 6) Version for a piece of software, for example a measurement tool. Description of a system clock
