[dc] A purpose of the draft /// Re: draft-khasnabish-vmmi-problems-00.txt

[Richard Bin liu <[e-mail]>]

Greetings David,

Thank you for your comments and question, it is a good question.
>From your viewpoint, "the interoperability between the different
vender (or SPs)" is the necessary condition of the "to work for the
IETF", but I think it is only a sufficient condition of the "to work
for the IETF", not a necessary condition, for example, do VM migration
between private desktop system with IPV6 addresses systems is not one
of the goals of the IETF? Of course yes. Whether or not to agree with
my viewpoint, seamless VM migration between a variety of computing
systems (servers, tablet PCs, mobile phone system) is an irreversible
trend in the future. Do IETF going to miss it?

So, I am sorry, in my personal viewpoint, your query is debatable.

See here, some people may be in doubt: Is the existing program can not
solve your problem?

Yes, the reasons for defect analysis of existing system can refer to
my following opinion(you can seach "traditional tunneling gateway" to
find it in this mail).

Many thanks for guidance

Regards,

Richard Bin Liu

In other words, there’s no work for the IETF to do because
interoperability is not a goal.  What have I missed?



Thanks,

Thomas, thank you for your comments!

About VM migration in the draft, we did not demand forcibly between
the different vender(or SPs), so your concerns may not
exist. As you say, "let's be realistic", our intention is to improve
the flexibility of VM migration, as well as the breadth
of applications under the premise of market heavyweights are not
opposed to it.In order to achieve these goals, analyse possible
problems, discuss and resolve these problems, such as: VM migration is
due to a non-public sector energy-efficient needs, rather than to
public access without interruption, or business needs of the user's
desktop migration, this demand may exist within a same service
provider, or you say a same vender with mixed network, for example:

With the promotion of IPv6 technology, the existing IPv4 networks will
be more and more IPv6 hosts, these applications driven
a series of tunnel technologies to provide solutions, such as: 6to4
tunnel technology, ISATAP tunnel technology, and so on.
Virtual machine migration technology will also be the basis of these
network environments,in the transition network using tunneling
transition technique, the connections between the subnets and the
backbone network are achieved through the tunneling gateway. In the
IPv4/IPv6 transition period, a variety of tunnels coexist. The
establishment of the tunnel varies with different gateways. The
traditional tunneling gateway only establishes tunnels for
communication with the same type of gateway, the different types of
traditional tunneling gateway cannot communicate with each other,
which cannot meet the requirements of VPN communications in the
transition period. A multi-tunnel VPN gateway is used to solve the
problem of establishing the tunnel between the heterogeneous gateways.

Many thanks for guidance
