Abstract: An apparatus for dispensing soft serve frozen food product, such as soft serve ice cream and the like, provides the ability to select the fat content or other characteristic of the ice cream dispensed from the machine.

Abstract: A packet switch interface, which may be an asynchronous transfer mode (ATM) layer interface chip, may be connected to the inputs or the outputs of a packet switch. The interface chip modifies the virtual path identifier and the virtual channel identifier in packets directed to and from the switch. The interface chip also manipulates routing tags for the packets which are used for internal routing purposes in the switch. The interface chip includes a local interface through which packets may be extracted from or added to a packet stream flowing between a main input and a main output of the interface. The interface chip polices different communications channels handled in the interface chip by detecting whether traffic in those channels exceeds certain network usage parameters. The interface is also capable of gathering certain statistical information about the traffic in certain communications channels to allow evaluation of network performance.
