Abstract: A method of estimating network latency including receiving intercept data (representing observations of requests sent by a client node and responses to the respective requests from a host node), detecting a burst of network traffic bounded by a first idle interval and/or second idle interval, and estimating download and/or upload latencies associated with the burst, wherein the download latency is estimated to be an amount of time between observation of an inferred first request of the burst from the client node until observation of a first response from the host node following the inferred first request, and the upload latency is estimated to be an amount of time between observation of a last inferred data packet of the burst from the host node to the client node until observation of a last inferred ACK packet from the client node following the last inferred data packet from the host node.

Abstract: A computer implemented method for determining the identity of an Over-the Top (OTT) application or service being accessed over the Internet from a HTTP, HTTPS or QUIC connection request received in a network monitoring device. Determine if one or more entries are present in the received connection request have an IP address that matches a known server IP address. A determination is then made as to whether if the received connection request is one of a HTTP, HTTPS or QUIC connection request, and if this cannot be determined than determine if a subject field in the received connection request is available. And determine if a candidate domain name is available from IP cache created from one or more of the above steps if a subject field is not available in the received connection request.
