The technology disclosed relates to real-time collection and flexible reporting of test data. In particular, it is useful when collecting packet counts during tests of network devices that simulate thousands or even millions of data sessions conducted through a device under test ('DUT').

A system for testing a segment of a data-packet-network has a first probe connected substantially at one end of the segment; a second probe connected substantially at the opposite end of the segment from the location of the first probe; and a process application distributed to each probe. The first and second probes collect data from and time stamp data packets as they pass forming first and second records of the individual packets whereupon the second-formed records of each packet are compared with the first records of each packet for record matching, time-stamp comparison and test result processing.

Method and apparatus for monitoring latency, jitter, packet throughput and packet loss ratio between two points on a network

A system for diagnosing impairments in computer networking services a plurality of connector gateways for interfacing to a plurality of data sources to provide access by the system to computer network data, business-related data, and extra-enterprise environmental data in the plurality of data sources. The system includes a knowledge manager in communication with each of the plurality of connector gateways for analyzing data from the plurality of data sources to generate diagnostic conclusions for resolving the impairments in the computer networking services. The system also includes an interactor in communication with the knowledge manager for generating format information for displaying at least the diagnostic conclusions to a user. The system can include a graphical user interface for displaying at least the diagnostic conclusions associated with edges of an edge model of the computer networking services of the user.

System and method for integrating multiple data sources into service-centric computer networking services diagnostic conclusions

A fault-testing node for a connectionless data link has at least two opposing communication ports; a soft switch for controlling port-to-port data flow through the device; and an instance of software for modifying packet header information. The node enables loop-back testing by one or more port-to-port data flow paths being switched through activation of the soft switch to loop incoming packets back to the sender of the packets through the device and wherein the instance of software reverses the order of source and destination addresses of data units to insure acceptance of looped data units at the sender station.
