Subject: [Int-area] RANGER BOF - call for participation

A community of interest is being formed to gauge
whether there is sufficient interest to host a BOF
on "Routing and Addressing in Next-Generation
EnteRprises (RANGER)" at IETF74.

Please see below for proposed BOF agenda, and comment
on the RRG and int-area lists while we wait for the
ranger list to come up.

RANGER [1] is a scalable architecture for routing and
addressing in next-generation enterprise networks, where
an "enterprise" [2] can be as small as a SOHO network,
as dynamic as a Mobile Ad-hoc Network (MANET) [3] or as
large as the global Internet itself [4]. The architecture
is manifested through Virtual Enterprise Traversal (VET)
[5], in which IP-in-IP encapsulation provides a virtual
view of each enterprise as a Non-Broadcast, Multiple-
Access (NBMA) link.

RANGER is recursive, in that multiple enterprises can be
joined together in a nested "enterprise-within-enterprise"
fashion. In this way, the same RANGER principles that
apply in lower levels of recursion can extend upwards
to parent enterprises and ultimately to the core of the
global Internet itself. Furthermore, it is also worth
considering whether today's global Internet represents a
limiting condition for recursion, or if other Internets
could be manifested as "parallel universes" and joined
together at still higher levels of recursion.

The RANGER architecture is manifested through composite
technologies including Virtual Enterprise Traversal (VET),
the Subnetwork Encapsulation and Adaptation Layer (SEAL)
[6], the Intra-Site Automatic Tunnel Addressing Protocol
(ISATAP) [7], and many others. Noting that combinations
with other technologies are also possible, the issues
addressed either in full or in part by RANGER include:

- IPv6/IPv4 coexistence and transition
- scalable routing and addressing
- provider-independent addressing and its
  relation to provide-aggregated addressing
- site mobility and multi-homing
- ingress filtering for multi-homed sites
- address and prefix autoconfiguration
- border router discovery
- router-to-router tunneling
- neighbor discovery over tunnels
- MTU determination for tunnels.

As seen in the above list, the RANGER architecture
provides a framework for addressing a broad range of
problem areas that currently limit the functionality,
growth and maturation of today's Internet. Therefore,
it is the purpose of this BOF to discuss the formation
of an IETF WG to produce the following work items:

1) An Informational RFC describing the RANGER architecture.
   This document to provide a high-level overview of the
   RANGER enterprise-within-enterprise framework, its
   constituent technologies, and its domain of

2) An RFC specification of Virtual Enterprise Traversal
   (VET). This document to specify the inner workings of
   IP-in-IP encapsulation and its associated mechanisms
   within the RANGER context.

3) An RFC specification of the Subnetwork Encapsulation
   and Adaptation Layer (SEAL). This document to specify
   an encapsulation sublayer used to provide enhanced
   packet identification and tunnel MTU robustness.

4) Other work items within scope as determined, e.g.,
   by working group/BOF consensus, etc.
