摘要： A redundancy architecture is described for network processing systems which allows the network to recover from failure of a network processing system without interruption in service. The redundancy architecture allows network processing systems that use state information to associate network traffic into discrete flows, to provide system level redundancy to prevent service outages, or loss of network traffic resulting from a failure in any single network processing system. The redundancy architecture includes an out-of-band network link between the redundant network processing systems. The out-of-band network link allows the network processing systems to exchange state and other data as necessary. By maintaining the state data not only for the network traffic being processed by the network processing system, but also the state data for the network traffic being processed by its mate network processing system, either network processing system can assume the network traffic of its redundant mate in the event of a failure.

摘要： 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.
