IDENTIFICATION OF DATA PACKETS

摘要

The invention relates to the identification of data packets in switching equipment (2) included in a telecommunication system (1) and known as a packet switch. A plurality of incoming links (4) are connected to the switching equipment (2) via first switch ports (3), and a plurality of outgoing links (6) are connected to the switching equipment via second switch ports (5). The equipment (2) also includes control means (10) and coupling devices (11) required to connect an incoming link (4) with an indicated link (6), where the indication of an outgoing link (6) is initiated by signals in the form of one or more data cells (30) occurring on an incoming link (4). Additional information in the form of additional bits (31) is delivered to the data cell (30) in the first switch port (3) and the additional bits are given a configuration which corresponds to the address information (32) in the data cell (30). The additional bits (31) are removed in the second switch port (5). Said additional bits include a category identification (31f) and/or a functional identification (31g).
