  • Methods, systems, and computer program products for monitoring network performance
    Patent number: 8976689
    Abstract: Network performance management includes identifying a location of a test unit, providing a test protocol to the test unit over a network, and transmitting a stream of data packets to the test unit. The network performance management also includes identifying, via the location of the test unit, a transmission path of network elements through which the stream of packets flows. The network performance management further includes tracking measurements associated with the stream of data packets transmitted to the test unit and return data packets received from the test unit. The measurements are tracked for segments associated with each of the network elements in the transmission path.
    Type: Grant

  • Method, device, and computer program product for detecting and encoding states for accurate measurement
    Patent number: 8929382
    Abstract: A method, device, and program for determining states in a flow of packets are provided. A flow of transmitted packets is received. When the difference between the sequence number of the arriving packet and the next expected sequence number is equal to zero and when the TTL number of the arriving packet is equal to the TTL number of the previous packet, there is a stable state beginning with the first of the consecutively received packets. If a difference between the sequence number of an arriving packet and a next expected sequence number is greater than 1, or TTL of the arriving packet is not equal to the TTL number of the previous packet, there is a not stable state. Time between end of one stable state and start of the next stable state is the hole, and the states and holes correlate to events for analysis of the network.

  • Facsimile machine transmission rate fall-back arrangement
    Patent number: 5050004
    Abstract: A facsimile machine is provided with a fall-back strategy arranged to track not only errors occurring in received scan lines randomly disposed over a received facsimile page, but also errors occurring in each of a series of scan lines. If the level of each such error at least equals the value of a respective threshold adapted to the current transmission rate and facsimile resolution, then the transmission rate is changed, in which case, the value of each threshold is changed in accordance with a new transmission rate.
