Abstract:
1. A method for connection set-up in a communication system which comprises a plurality of first processing units and a plurality of second processing units, said method comprising: transmitting information as a stream of information cells having cell identification, wherein the plurality of first processing units are connected to the plurality of second processing units using virtual path connections on an asynchronous transfer mode layer; supplying information cells to a plurality of second processing units which distinguish between the cells based on the cell identification for further processing, generating virtual path connections between the plurality of first processing units and the plurality of second processing units and between each of the plurality of first processing units; copying using the first processing units, in the direction towards the second processing units, each received cell to each second processing unit; checking a virtual path identifier and a virtual channel identifier of a received cell; and processing using a second processing unit a received cell when the received cell has the same virtual path identifier and virtual channel identifier as a channel opened in the second processing unit, otherwise discarding the received cell by the second processing unit, wherein the plurality of first processing units or the plurality of second processing units share the same virtual path.
