System and methods for modifying streaming data based on radio frequency information is provided. As radio transceivers transition move to a shared resource or cloud model and the existing radio transceivers are split into a baseband unit and a remote radio head, radio frequency (RF) information including power levels, encoding, data rates, and bandwidth can be provided to video optimization server. The RF information can be provided more frequently to allow real-time modifications to streaming video data. Existing protocols are reactionary in nature and perceive changing channel conditions indirectly. By providing RF information from the baseband unit on a low latency channel, modifications to the video stream can be made before an impact would be noticed at the protocol level. Also, policy information can be used to influence the changes made to streaming data in addition to the RF information.

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.

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.

A system and method for metadata analysis and collection with privacy is disclosed. According to one embodiment, a trusted third party (TTP) system generates and transmits authorization keys to a government agency (GA) system and a communication service provider (CSP) system. The TTP system receives index records referencing records of subscribers from the CSP system and ingests the index records received from the CSP system. The TTP system receives a target index request from the GA system and sends a metadata record request to the CSP system based on the target index request. The CSP system sends metadata records to the TTP system, and the TTP system delivers the metadata records to the GA system. The metadata records are encrypted with encryption keys shared between the GA system and the CSP system such that the TTP system cannot decrypt the metadata records.

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.

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.

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.

Techniques are described for fulfilling a request for services in a federated peering environment. Embodiments receive an advertisement of offered services from each of a plurality of service providers. Such an advertisement may specify a list of offered services and pricing information for the services. A request for one or more services is received from a client at a first service provider. Embodiments determine a second service provider from the plurality of service providers to peer with to dynamically create a federation of peers for fulfilling the service request, based on the received advertisements of offered services and the requested services. Embodiments then peer with at least the determined second service provider to dynamically create a peered federation and fulfill the service request through the created federation of peers.

According to one embodiment, a system includes one or more memory units for storing an Address Resolution Protocol (ARP) table. The system further includes one or more processors. The processors receive, from a routing protocol, an Internet Protocol (IP)-Media Access Control (MAC) address pair for a first host computer. The processors further populate the ARP table with the IP-MAC address pair for the first host computer.

System and method for facilitating communication

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. 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.

A system and method for defending a mobile network from a fraud committed via GTP is disclosed. According to one embodiment, a computer-implemented method includes receiving receives information associated with a GTP request from a serving node to a gateway node in a mobile network. The information associated with the GTP request is a GTP control plane request or a CDR associated with the GTP request. The information associated with a GTP request is examined, and parameters contained in the information associated with the GTP request are analyzed. It is determined that the GTP request is a fraudulent GTP request if the parameters do not belong to an authorized subscriber of the mobile network. A GTP tunnel associated with the fraudulent GTP request is denied, an established fraudulent GTP tunnel is deleted, or network traffic established by a fraudulent GTP tunnel is redirected to a monitoring node.
