US 5,845,086 A · System for addressing a destination station using only address of a network junction and station link identifier in a network with plurality of segments

Abstract

A process and a device for addressing stations in a network consisting of at least two segments (S1, S2, S3), wherein network junctions (N1, N2) are provided between the individual segments, which network junctions forward a message from a first segment (S1) to other connected segments (S2, S3) on the basis of path information contained in messages for addressing. The path information of a message to be forwarded through a network junction (N1) contains the station address, valid in the first segment (S1), of the network junction (N1) and an address extension containing a station link identifier for the network junction (N1), and with the help of said address extension the network junction (N1) inserts path information, valid in the other segment (S2), in the message for addressing the receiving station (E2, E3) and forwards it to the other segment (S2). The path information for each station link that can be established via a network junction are advantageously stored in a transmission table. Such transmission tables can be generated automatically by a special procedure in the network junctions.

Dependent claims

A process for addressing stations in a network containing at least two segments and network junctions arranged between the at least two segments, wherein the network junctions forward a message from a first of the at least two segments to another of the at least two segments on the basis of path information contained in an addressing message, the process comprising the steps of:

forwarding a message through one of the network junctions, the message including path information containing a station address of the network junction and an address extension, wherein the station address is valid in the first segment and the address extension includes a station link identifier, which address extension uniquely identifies for the network junction a link that is to be established in the network between a transmitting station and a receiving station via the network junction;
forwarding, from the network junction, the message to another segment if the station address of the network junction agrees with the received station address in the path information;
and
updating, at the network junction in accordance with the station link identifier, the path information of the message for addressing the receiving station, wherein the path information is valid in the other segment.
