Abstract

   The Internet and its architecture have grown in evolutionary fashion
   from modest beginnings, rather than from a Grand Plan. While this
   process of evolution is one of the main reasons for the technology's
   success, it nevertheless seems useful to record a snapshot of the
   current principles of the Internet architecture. This is intended for
   general guidance and general interest, and is in no way intended to
   be a formal or invariant reference model.

1. Constant Change

   In searching for Internet architectural principles, we must remember
   that technical change is continuous in the information technology
   industry. The Internet reflects this.  Over the 25 years since the
   ARPANET started, various measures of the size of the Internet have
   increased by factors between 1000 (backbone speed) and 1000000
   (number of hosts). In this environment, some architectural principles
   inevitably change.  Principles that seemed inviolable a few years ago
   are deprecated today. Principles that seem sacred today will be
   deprecated tomorrow. The principle of constant change is perhaps the
   only principle of the Internet that should survive indefinitely.
