Analysis of Inter-Domain Routing Requirements and History
Abstract
This document analyzes the state of the Internet domain-based routing
system, concentrating on Inter-Domain Routing (IDR) and also
considering the relationship between inter-domain and intra-domain
routing. The analysis is carried out with respect to RFC 1126 and
other IDR requirements and design efforts looking at the routing
system as it appeared to be in 2001 with editorial additions
reflecting developments up to 2006. It is the companion document to
"A Set of Possible Requirements for a Future Routing Architecture"
(RFC 5772), which is a discussion of requirements for the future
routing architecture, addressing systems developments and future
routing protocols. This document summarizes discussions held several
years ago by members of the IRTF Routing Research Group (IRTF RRG)
and other interested parties. The document is published with the
support of the IRTF RRG as a record of the work completed at that
time, but with the understanding that it does not necessarily
represent either the latest technical understanding or the technical
consensus of the research group at the date of publication.
