Abstract
In an ATM communication network ATM cells to be transmitted from a terminal device (46) to a network control node (12) are transmitted according to certain transmission properties also called Quality of Service. In order to determine the Quality of Service with which a given packet has to be transmitted, the Quality of Service is determined from address information in the VPI/VCI identifier in the header of the ATM cell. In an embodiment of the invention a network termination (32) comprises address translation means (76) for translating the address present in ATM cells received from the terminal device (46) into addresses indicating the Quality of Service
Claims10
Communication network comprising a plurality of secondary nodes being coupled to at least one primary node, said secondary nodes being arranged for transmitting packets to the primary node according to predetermined transmission properties, characterized in that the secondary node comprises selection means for selecting packets according to address information in their header, and in that the transmission means are arranged for transmission of said packets with transmission properties dependent on the selection performed by the selection means.
Node for use in a communication network, said node being arranged for transmitting packets according to predetermined transmission properties to a primary node, characterized in that the secondary node comprises selection means for selecting packets according to address information in their header, and in that the transmission means are arranged for transmission of said packets with transmission properties dependent on the selection performed by the selection means.
Communication method comprising transmitting packets according to predetermined transmission properties, characterized in that the communication method comprises selecting packets according to address information in their header, and in that the communication method comprises transmission of said packets with transmission properties dependent on the selection performed.
