UBR traffic class for ATM with and without weighted priorities

摘要

An ATM communication system including a source which produces traffic for connections having known traffic characteristics and unknown traffic characteristics. The traffic having unknown characteristics including traffic with weighted priorities and traffic without weighted priorities. The source sends the traffic having known traffic characteristics and unknown traffic characteristics onto the network. The system includes a destination which is connected to the network and receives the traffic having known traffic characteristics and unknown traffic characteristics. A switch for switching traffic on an ATM network from a source to a destination. The switch includes a mechanism for receiving traffic for connections having unknown traffic characteristics and transmitting including traffic with weighted priorities and traffic without weighted priorities. The switch includes a scheduler for scheduling when the connections having traffic with unknown characteristics having weighted priorities are to be transmitted to the network. The scheduler is connected to the transmitting mechanism and the receiving mechanism. A method for transferring traffic in an ATM communication system. The method includes the steps of transmitting from a source traffic of a connection having unknown traffic characteristics with a weighted priority onto an ATM network. Then there is the step of transmitting from the source traffic of another connection having unknown traffic characteristics without a weighted priority onto the ATM network.
