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. Identify and categorize OTT applications associated with the received connection request if it is determined: the connection is either a HTTP, HTTPS or QUIC connection type; a subject field is available; or a candidate domain name is available utilizing a lookup table that is periodically updated with new OTT applications.
