Abstract: A method, apparatus and computer program product for performing optimized distributed routing for stretched data center models through updating route advertisements based on changes to Address Resolution Protocol (ARP) Tables is presented. Port members of an Internet Protocol I (IP) interface or Virtual Local Area Network (VLAN) are distinguished into Access Interfaces which only lead to hosts on said subnet and Trunk Interfaces which lead to other redundant routers on said subnet. In the subnet of a network a network route for the subnet is always advertised. A separate host route corresponding to an Internet Protocol (IP) address of each Address Resolution Protocol (ARP) table record that points to an Access Interface is advertised and route advertisements are changed for a host in said subnet for tracked access interfaces.

Abstract: An imaging apparatus and an imaging method includes an imaging unit to collect light input through a lens and sensing an image, a storage unit to store an acquisition condition and the sensed image, a control unit to designate a plurality of objects in the stored image, to analyze respective motion of the plurality of objects, and to predict a moment of acquisition at which the motion corresponds to the acquisition condition, and a shutter control unit to control the imaging unit to perform imaging at the predicted moment of acquisition.
