English to Italian Law/Patents IT (Information Technology) anomalies in a communication system

to reduce the number of samples of the symbolic packet features, the values
of the symbolic packet feature can be grouped or hashed into a smaller set of values. For example, only some bits of a
32-bit IP address can be chosen. More generally, only some linear functions of bits of a 32-bit IP address can be chosen.
As known to the skilled person, a (conventional) hash function is a reproducible method of turning original data, belonging
to a symbolic data set, into hashed data belonging to a reduced symbolic data set, which contains a reduced number
of discrete values. The hashed data is also called a digital "fingerprint" or digest of the original data.
