  • Minimally invasive monitoring of path quality
    Patent number: 10355944
    Abstract: Systems and techniques are described for performing minimally invasive monitoring of path quality in a network. Specifically, path quality requests and measurements can be piggy-backed on the data traffic that is flowing through a secure connection between two network nodes. For example, path quality requests and measurements can be inserted into the TFC padding field of IP/ESP packets that are being communicated between two IPsec devices. The disclosed embodiments ensure that the number/frequency of measurements increases/decreases naturally in proportion to the amount of traffic flowing, and that the measurement data does not get differential treatment in the network as they are intrinsically bound to the data packets being monitored.
    Type: Grant
