Abstract
A method and apparatus for performing address translation in an ATM network element, such as a switch, resulting in minimized circuit complexity and resultant cost savings. The present invention includes the generation of a simplified local address from elements of internetwork communications, the local address being suitable for addressing a routing table in the network element. Components of the local address are also individually employed as masks for out-of-range checking.
