Abstract

This memo is an informational RFC which outlines one potential approach for inter-domain routing in future global internets. The focus is on scalability to very large networks and functionality, as well as scalability, to support routing in an environment of heterogeneous services, requirements, and route selection criteria.

1.0 Motivation

   The global internet can be modeled as a collection of hosts
   interconnected via transmission and switching facilities.  Control
   over the collection of hosts and the transmission and switching
   facilities that compose the networking resources of the global
   internet is not homogeneous, but is distributed among multiple
   administrative authorities.  Resources under control of a single
   administration form a domain.  In order to support each domain's
   autonomy and heterogeneity, routing consists of two distinct
   components: intra-domain (interior) routing, and inter-domain
   (exterior) routing.  Intra-domain routing provides support for data
   communication between hosts where data traverses transmission and
   switching facilities within a single domain.  Inter-domain routing
   provides support for data communication between hosts where data
