Abstract: A deep packet inspection (DPI) allocator for managing bandwidth in a communication channel, the DPI allocator comprising: a DPI application for inspecting data packets propagating to a destination via the channel that enter the allocator; and at least one service application for processing data packets that enter the allocator.

Abstract: The present invention provides a cellular traffic monitoring system, which includes: a traffic detection function (TDF) module to monitor cellular traffic associated with a cellular subscriber device, and to generate detection output which includes at least one of: a type of an application associated with said cellular traffic of said cellular subscriber device, and a type of said cellular traffic of said cellular subscriber device. The further includes a policy charging and enforcement function (PCEF) module to enforce one or more charging rules to said cellular subscriber device, based on said detection output.

Abstract: A hash unit, including an input interface adapted to receive an input key, an arbitrary number generator adapted to generate one or more arbitrary numbers, a processor adapted to apply a multi-operand function to an input key received by the input interface together with each of one or more arbitrary numbers generated by the generator so as to generate intermediate results, to mathematically combine the digits of the intermediate results to generate respective short bit results having less than half the bits of the intermediate results and to concatenate the short bit results and an output unit adapted to provide the concatenated short bit results for use as an output hash key.
