This document was submitted to the IETF IPng area in response to RFC
1550. Publication of this document does not imply acceptance by the
IPng area of any ideas expressed within. Comments should be
submitted to the email@example.com mailing list. This draft
summarizes some of the requirements of large corporate networks for
the next generation of the Internet protcol suite.
As more and more corporations are using TCP/IP for their mission-
critical applications, they are bringing additional requirements,
summarized below, the satisfaction of which would make TCP/IP even
more appealing to businesses. Since these are requirements rather
than solutions, we include capabilities that might be provided in
protocol layers other than the one that IPv4 occupies; i.e., these
items might lie outside the scope typically envisioned for IPng, but
we'll refer to them as IPng requirements nonetheless. When we
mention potential solutions, it is not to suggest that they are the
best approach, but merely to clarify the requirement.
Among business users the major requirements we see for IPng are:
-- smooth migration from, and coexistence with, IPv4;
-- predictable levels of service for predictable costs;
-- security; and
-- accommodation of multiple protocols suites.
We also mention several more specific requirements.
IPng must have a viable strategy for migration from, and coexistence
with, IPv4. IPv4 and IPng must coexist well, because they will need
to do so for several years. To encourage IPv4 users to upgrade to
IPng, IPng must offer compelling advantages and an easy migration
Corporate networks must meet promised levels of service while
controlling costs through efficient use of resources. The IETF
should consider both technical solutions (such as service classes and
priorities) and administrative ones (such as accounting) to promote
Many businesses will not connect to a network until they are
confident that it will not significantly threaten the
confidentiality, integrity, or availability of their data.
Corporations tend to use multiple protocols. Numerous forces stymie
the desire to settle on just one protocol for a large corporation:
diverse installed bases, skills, technical factors, and the general
trend toward corporate decentralization. The IETF needs a strategy
for heterogeneity fl...
