Abstract
A method and system for providing a standardized set of filters for a router. A set of pre-written filters are provided in a file, and a program is run on a computer to identify one of these pre-written filters as a substitute for a filter that was specifically written for the router. The standardized filter file is then loaded onto the router and the identified substitute filters are used instead of the filter that has been specifically written for the router. Preferably, the computer program is used to identify which one of the pre-written filters of the pre-written filter files most closely matches, according to a predefined test, the filter file written specifically for the router.
