  • Network link monitoring and testing
    Patent number: 8937870
    Abstract: In some embodiments, a link monitoring system (“LMS”) is configured to obtain link status metrics and packet transmission metrics for network links forming a network channel between a first network device and a second network device. The LMS can obtain link status metrics from the first network device and the second network device and can also initiate the generation of packets on the network links to obtain the packet transmission metrics. Based on the status metrics and packet transmission metrics, the LMS can determine if the network links are malfunctioning.
