Abstract: A system and method for discovering user equipment in a network is disclosed. According to one embodiment, a discovery proxy periodically scans an access router that serves a target user equipment and collects an address assignment record of the target user equipment via the access router. The discovery proxy passes the address assignment record to a discovery server, and the discovery server identifies a location of the target user equipment based on the address assignment record of the target user equipment.

Abstract: A system and method for discovering Internet Protocol (IP) network address and port translation bindings is disclosed. According to one embodiment, a system for creating IP data records, includes a carrier grade network address and port translation (CGNAPT) node in communication with a private network on an internal side and a public network on an external side. The system further includes a private Ethernet span port disposed on the internal side of the CGNAPT node that receives packet streams traversing the CGNAPT node. A public Ethernet span port is disposed on the external side of the CGNAPT node that receives packet streams traversing the CGNAPT node. The private Ethernet span port and the public Ethernet span port copy packet streams traversing the CGNAPT node and deliver the copied packet streams to a deep packet inspection host.

Abstract: A method and system for enabling peer-to-peer (P2P) communication between a first device and a second device is disclosed. According to one embodiment, a P2P communication system includes a first peer agent serving a first peer, a second peer agent serving a second peer, and a rendezvous server. The rendezvous server updates a first IP address for the first peer agent to the second peer agent and a second IP address for the second peer agent to the first peer agent. The first peer agent and the second peer agent communicate with the rendezvous server by dropping and retrieving a plurality of dead-drop packages. A first dead-drop package of the plurality of dead-drop packages comprises a first alias that is known only to the first peer and the second peer. A second dead-drop package of the plurality of dead-drop packages comprises a second alias that is different from the first alias.

Abstract: A data replication system of a communication network is disclosed. According to one embodiment, the data replication system includes a replication gateway node and a replication control system located in one or more of a visited network and a home network. The replication gateway node is configured to create a first replication tunnel between a first gateway node and the replication gateway node and a second replication tunnel between the replication gateway node and a second gateway node. The replication gateway node replicates data streams between the first gateway node and the second gateway and delivers the replicated data stream to a management node for further analysis.

Abstract: Systems and methods for scalable and iterative deep packet inspection for communication networks are disclosed. According to one embodiment, a system comprises a home network and a visitor network in communication with the home network over an Internetwork packet exchange. The visitor network may have an intercept area with an intercept probe, a local packet data network gateway (PGW) and a local proxy-call session control function (P-CSCF). The system further includes a diameter edge agent that monitors signaling traffic in the visitor network passing to and from the home network. The system also has a targeting system in communication with the diameter edge agent that redirects the signaling traffic from the home PGW to the visiting PGW.
