Abstract
Asynchronous Transfer Mode (ATM) network Quality of Service (QoS) guarantees are extended to Token Ring LAN stations. A LAN station originating a request for a connection through an ATM network to either a remote ATM station or a remote LAN station sends a frame having an encoded priority value to a LAN/ATM interface device. The device maps the priority value to one of the standard ATM traffic classes; namely, CBR, VBR, ABR and UBR. The LAN/ATM interface device attempts to set up a connection through the ATM network conforming to the mapped class or QoS. If the connection destination is another LAN station, a destination LAN/ATM interface device attempts to set up the final ATM-LAN phase of the connection.
