Abstract
A technique for providing a device referred to as a transparent bump between a local area network and a router. The device is inserted with minimal intrusion to the devices on the LAN to provide a certain operation, such as web caching. The device initializes at start-up in the promiscuous mode to learn the MAC address of the router and subsequently accepts data packets destined to the router for internal processing. Accesses to a web page are checked in the device to determine if cached data is present, so that redundant accesses are reduced. The device initializes and performs its intended function transparently to a user on the local area network.
