  • Method and system for measuring packet loss
    Patent number: 10063440
    Abstract: In a method of measuring packet loss, a flow of packets is identified at first and second locations in a network. The packets in the flow are counted at each of the first and second locations to provide first and second packet counts, respectively. When a trigger packet in the flow is identified at each of the first and second locations, the first and second packet counts are latched to provide latched first and second packet counts corresponding to same packets in the flow. The latched first and second packet counts are compared to measure packet loss between the first and second locations.
    Type: Grant

  • Method of extracting network information
    Patent number: 5892908
    Abstract: A method of extracting network information first receives an initial link address (102) and retrieves a file (104) associated with the initial link address. The file is then parsed (106) to find a hyper text link. Next it is determined (108) if the hyper text link has a link address that contains the network address as a root. When the link address contains the initial link address as the root, a link file associated with the link address is retrieved (110).
