Abstract: In one embodiment, an apparatus includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the apparatus to perform operations including receiving a first type-length-value (TLV) associated with a winning flexible algorithm definition (FAD) from a first element of a network. The operations also include determining a security level for the winning FAD based on the TLV. The operations further include determining a data transmission route through a plurality of elements of the network based on the security level for the winning FAD.

Abstract: A method, system and associate peripheral device for remotely teaching piano. The device (13/23) comprises a plurality of indicator LEDs along its length for arrangement/alignment across a student piano keyboard (11). When a key is triggered on a remote piano keyboard (21), e.g., by a teacher, one of the LEDs lights up at the equivalent key at the student piano keyboard. The system also allows for playing notes from the student or teacher piano keyboard, communicated over the internet, at the teacher or student piano keyboard and vice versa.

Abstract: In one embodiment, a link state advertisement is generated. A first value and a second value are read from the link state advertisement. The first value and the second value are combined to create a combined value. The combined value is input to a hash algorithm that performs a hash function on the combined value to produce a resulting value. The resulting value is used as a link state identifier of the link state advertisement.

Abstract: In one embodiment, a technique is used by a routing system to generate a link state identifier for a link state advertisement message. The routing system generates the link state advertisement message. A prefix length is read from the link state advertisement message. Further, a prefix is read from the link state advertisement message. A hash function is performed on the prefix and the length to produce a result by appending the length to the prefix to generate a combined value, inputting the combined value to a hash algorithm, and using at least a portion of an output of the hash algorithm as the result. The link state identifier is determined from the result of the hash function.
