> Where is the edge of the Internet? here's what i came up with while trying to explain "the edge" elsewhere. 1 - Connection Taxonomy 1.1. The Internet is a "network of networks", where the component networks are called Autonomous Systems (AS), each having a unique AS Number (ASN). 1.2. Connections inside an AS are called "Interior" (or sometimes "backbone"), and their security policies are set according to local needs, usually based on business or technical requirements. 1.3. Connections between ASs are called "Border" (or sometimes "peering"), and their security policies are set bilaterally according to the joint needs of the interconnecting parties. 1.4. Connections between an AS and its traffic sources (generators) and traffic sinks (consumers) are called "Edge" (or sometimes "customer"), and their security policies are generally, by long standing tradition, nonexistent. -- Paul Vixie
