ABSTRACT:
A method for rapidly accessing address features of communication subscribers, in particular, when reading data packets is provided. Performance features of the communication connection are deposited in tables in the form of addresses that must be successively searched. A large address area from which a sub-set of addresses is used, is compressed onto a compressed address area of the same size as the sub-set of the addresses used, thereby obtaining miniaturized addresses. Since a plurality of tables must be searched per address entry, different tables to be checked are activated via offsets proceeding from the compressed address area. The communication load for the address transfer is reduced as a result and a shortened calculating time is achieved in comparison to a hash addressing.
