Abstract: A method, apparatus and computer program product are provided for implementing enhanced proxy Address Resolution Protocol (ARP) for Virtual Internet protocol (IP) addresses. A Virtual Internet protocol (IP) interface requiring proxy ARP is identified and a proxy agent for the Virtual Internet protocol (IP) interface is dynamically selected. An IP address for the Virtual Internet protocol (IP) interface is added to an address list of a physical adapter for the selected proxy agent. Utilizing the physical adapter for the selected proxy agent, the added IP address for the Virtual Internet protocol (IP) interface is broadcast with a media access control (MAC) address of the physical adapter for the selected proxy agent.

Abstract: A continuous pneumatic tobacco conveyance system is described which automatically controls the rate at which tobacco is fed into the conveyance system and automatically controls the velocity of the tobacco which is pneumatically conveyed. The system utilizes a plurality of programmable logic controllers for analyzing the velocity of the tobacco in the system and the amount of tobacco required and currently existent in cigarette making machine. The system compensates for correct airflow and velocity of the tobacco in the pneumatic piping by controlling the rate at which tobacco is fed into the conveyance system and controlling the airflow required to move the tobacco at a continuous velocity by adjusting a flow control valve attached to a vacuum source.
