Subject: IPv6 Test Network 6bone
Date: Tue, 02 Apr 96 12:57:33 -0500
My name is Jim Bound and I am working with an informal group of IETF
colleagues to define and set up a world-wide test network for IPv6. Brian
Carpenter from CERN gave me your name as one who may be interested in this
work. My day job is at Digital Equipment Corporation in the U.S. where I am
the IPv6 Technical Director. We have initial participants from multiple
vendors, universities, research, and network operators across North
America, Europe, and Japan.
I have attached our DRAFT charter of "What is the 6bone". Its critical
we have European participation for this effort.
Brian has shared with me what RENATER is and it appears to be a good
place to add IPv6 nodes as part of the 6bone. We also need
leadership support to integrate 6bone across Europe.
Are you interested in participating in this effort? If so we could
add you to our 6bone mailing list as we develop the details of 6bone, as
a first step?
What is the 6bone?
The 6bone is an independent outgrowth of the IETF IPng project that
resulted in the creation of the IPv6 protocols intended eventually to
replace the current Internet network layer protocols known as IPv4.
The 6bone is currently an informal collaborative project covering
North America, Europe, and Japan.
One essential part in the IPv4 to IPv6 transition is the development
of an Internet-wide IPv6 backbone infrastructure that can transport IPv6
packets. As with the existing IPv4 Internet backbone, the IPv6
backbone infrastructure will be composed of many Internet Service
Providers (ISPs) and user networks linked together to provide the
Until the IPv6 protocols are widely implemented and fully tested for
interoperability, production ISP and user network routers will not
readily place production Internet (IPv4) routers at risk. Thus a way
is needed to provide Internet-wide IPv6 transport in an organized and
orderly way for early testing and early use.
The 6bone is a virtual network layered on top of portions of the
physical IPv4-based Internet to support routing of IPv6 packets, as
that function has not yet been integrated into many production
routers. The network is composed of islands that can directly support
IPv6 packets, linked by virtual point-to-point links called "tunnels".
The tunnel endpoints are typically workstation-class machines having
operating system support for IPv6.
Over time, as confidence builds to allow production routers to carry
native IPv6 packets, it is expected that the 6bone would disappear by
agreement of all parties. It would be replaced in a transparent way
by production ISP and user network IPv6 Internet-wide transport.
The 6bone is thus focused on providing the early policy and procedures
necessary to provide IPv6 transport in a reasonable fashion so testing
and experience can be carried out. It would not attempt to provide
new network interconnect architectures, procedures and policies that
are clearly the purview of ISP and user network operators. In fact,
it is the desire to include as many ISP and user network operators in
the 6bone process as possible to guarantee a seamless transition to
