Abstract: Systems and techniques for increasing wireless network performance using contextual fingerprinting are described herein. Performance metrics may be obtained for a client device-access radio pair that includes a wireless network interface of a client device and an access radio of a wireless network associated with the client device. A fingerprint may be generated for the client device-access radio pair. The fingerprint may be stored in a fingerprint store for the wireless network.

Abstract: Methods, apparatuses and computer programs for protecting a network against forged messages, or impersonation attacks, which do not require the use cryptography. One or more nodes on the network are configured to detect a forged message and to output an indication that a forged message has been detected. Nodes that receive an indication that a forged message has been detected may then take certain actions, such as, for example, discontinuing use of the protocol associated with the forged message for a period of time.

Abstract: A method for surveilling a telecommunications network link includes disposing a link demarcation device (LDD) at a point on a network link, the LDD dividing the network link into a first network link section and a second network link section, the LDD being configured to perform self-monitoring and monitoring of the first and second network link sections, operating the LDD to transmit one of a plurality of unique fault-indicating signals based upon a specific detected fault-indicating condition, wherein each of the unique fault-indicating signals corresponds to a detected fault-indicating condition, detecting the unique fault-indicating signal with a link delimiting device (LLD) communicatively coupled to the LDD by one of the first and second network link sections, and unambiguously identifying the unique fault-indicating signal with the LLD, wherein the unique fault-indicating signals are selected to be readily distinguishable by an existing detection and alarming capability of the LLD.
