Abstract: A device for realizing upstream aggregation and downstream translation of a virtual local area network (VLAN) includes a buffer and a processor. The buffer is used for storing an ingress VLAN translation table and an egress VLAN translation table. The processor is used for translating an upstream packet inputted from a first user port into an upstream translation packet according to the ingress VLAN translation table, and transmitting the upstream translation packet to the Internet through an internet port, and translating a first downstream packet inputted from the internet port into a first downstream translation packet according to the egress VLAN translation table, and transmitting the first downstream translation packet to a user device through a second user port.

Abstract: A computer controlled system and method of using the system for control of shipping a quantity of product either domestically or internationally. The system comprises a number of user input stations for entering a shipping request. Product release information stored in the computer is added to the request which is transmitted t a product storage unit, a printer, and an exit control station. The product storage unit selects the product requested. The printer prints a product release form which can include a customs declaration form and/or a digital authentication stamp if desired. The product is prepared for shipping and the product release form is attached. The product and the product release form is checked at the exit control station. The product is then shipped or corrective action is taken.
