in SAC 004 (http://www.icann.org/committees/security/sac004.txt) we see: 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, inconsistent. the rest of the paper is also germane to this thread. just fya, we keep rehashing the UNimportant part of this argument, and never progressing. (from this, i deduce that we must be humans.) -- Paul Vixie
