Interference signals are detected in a multi-layer wireless communication systems, which have a frequency spectrum that is captured by using a spectrum analyzer. Thereafter, an occurring interference type is identified based on image of the frequency spectrum. In response, an interference mitigation solution is engaged which corresponds to the identified interference type. The interference mitigation solution can simultaneously deploy or change one or more forward error correction (FEC) protocols on each of two or more of the layers along with other related system parameters. Related apparatus, systems, techniques and articles are also described.

Multi-layer forward error correction (FEC) for jamming resiliency

Described are systems, methods, and computer-program product embodiments for providing Session Initiation Protocol (SIP) network security. In some embodiments, a SIP processing system includes a SIP device configured to receive a packet stream from a first SIP user agent and facilitate a SIP communication session between the first SIP user agent and a second SIP user agent. The SIP device receives the SIP messages in the SIP communication session and opens one or more socket connections with one or more security systems. The SIP device transmits metadata of the SIP messages to the one or more security systems configured to detect threats. Based on a threat status generated by and received from the one or more security systems, the SIP device controls the SIP communication session.

Deploying session initiation protocol application network security

Described are systems, methods, and computer-program product embodiments for providing Session Initiation Protocol (SIP) network security. In some embodiments, a SIP processing system includes a SIP device configured to establish and control a SIP communication session between SIP user agents. In some embodiments, the SIP processing system includes a SIP device that establishes a recording session with a first server to receive SIP messages relayed in the SIP communication session. The first server decodes the SIP messages based on metadata in the SIP messages to extract multimedia content. Then, the first server opens a socket connection to establish a security session with a security system configured to determine whether the portion is associated with a detected threat and transmits a portion of the decoded multimedia to the security system. Based on a threat status generated by and received from the security system, the first server controls the SIP communication session.
