Memo on "Toward 10% of R&E network traffic"
Kilnam Chon

"Toward 10% of R&E network traffic" is the subtitle of APAN IPv6 Task Force
objective. It is a simple concept, but there may be some confusion on the
concept. I will clarify and explain on this matter.

APAN IPv6 Task Force with the objective of develop IPv6 traffic toward 10%
of the R&E network traffic. When the 10% traffic for IPv6 will be accomplished,
then the task force will be assessed if we may disband the task force.

When we start the new service such as the production service deployment of
IPv6 in APAN, we start from the zero traffic. If we are successful on
the traffic development campaign, then we would reach to 10%, followed by
50% and more. The remaining traffic(i.e., the balance of the traffic) is of
IPv4. When do we stop the campaign of concentrated effort is one of the issues
the task force has to look into, and there are the following(and more) choices;
0%, 10%, 20%, 50%, and 100%.

1. 0%
This is the choice of Internet 2 among others, i.e., Internet does not
any direct approach to build up the traffic. They tend to take the approach
of dual stack.

2. 10%
This is the target(or stopping rule) we are proposing at APAN for IPv6
deployment. This is an optimistic approach. We expect IPv6 starts
snowballing when it reaches to 5~20% of the traffic, and we don't want
to over-engineering the deployment as it may distort the natural traffic
development.

3. 20%(~25%)
System engineering tells us that once a service buildup reaches 20~25%,
it starts snowballing. i.e., takeoff points are usually 20~25%.

4. 50%
This implies that there are equal traffic; IPv6 and IPv4.

5. 100%
This implies the transition, and IPv4 is to be phased like. US DoD takes
this approach, partially it is of intranet and it simplified the operation
(if you can afford it).
