Abstract
A method is described for detecting rogue packets in real-time protocol (“RTP”) data streams. Rogue packets occur due to a malfunctioning device continuing to send RTP packets after the termination of the media session, or by third party devices due to malfunction or malicious activity. The method recognizes rogue RTP packets by examining identifying fields in each packet associated with the RTP stream. The fields can be in the header of the packet or in the payload, and can include information such as destination address, destination port, protocol, sequence number, SSRC number, and others. Once rogue activity is detected the method can quarantine the associated pinhole information and/or alert a network operator.
