Abstract:
A system for transmitting cells of internal traffic between computer units in a broadband telecommunication system which comprises:an ATM switch which has at least one input port and a plurality of output ports and which switches an internal traffic cell applied to the input port to an output port, a connection control unit which, as a response to a request sent by the party requesting the connection, the request including the party's traffic and quality parameters as well as the desired service category, decides whether the connection can be accepted and in the affirmative case establishes a virtual connection to another party, at least one computer unit controlling the switch, in which at least one application is running, wherein the at least one application communicates with applications in other computer units, wherein each computer unit has an entity carrying out ATM adaptation layer functions, the entity inserts information which was generated by the application and is to be transmitted into the data section of the internal traffic cell and the entity correspondingly combines the data sections of the cells received from the other applications into received information, each computer unit comprises an entity handling communications, which, as a response to the application's request to be allowed to transmit information to an application in another computer unit, transmits the application's traffic and quality parameters as well as the desired service category to the connection control unit, whereby the application is able to act as the party requesting a connection from the ATM switch, the service category requested by all the applications are at least selected connection-specifically.
