TUNNELING SCHEME OPTIMIZED FOR USE IN VIRTUAL PRIVATE NETWORKS

摘要

A tunneling scheme includes the creation of tunnels having a source addre ss and potentially multiple destination addresses. Each tunnel endpoint is divided into two sub-endpoints, where one sub-endpoint has a public network address and t he other sub-endpoint has a private network address. Also included in the tunneling scheme is a static Address Resolution Protocol (ARP) table. The static ARP table contains information on virtual private network membership. More particularl y, the static ARP table provides address resolution between public network addresse s and private network addresses.
