1. In a component for being disposed in a communication system including at least one other component, an apparatus comprising:

  • means for establishing a virtual connection through the communication system between the component and the at least one other component;

    receiving means for receiving information frames transmitted over the virtual connection from the at least one other component;

    transmitting means for transmitting information frames over the virtual connection from the component to the at least one other component; and

    a state machine, coupled to the transmitting means, that controls use of the virtual connection by the component, the state machine defining a live state of the virtual connection wherein a minimum bandwidth is guaranteed for transmission of information frames between the component and the at least one other component over the virtual connection, the state machine further defining a dormant state of the virtual connection wherein the minimum bandwidth is not guaranteed for the transmission of information frames between the component and the at least one other component over the virtual connection.
