Re: [tlug] IPv6

Hello!

This is not an area I am particularly well versed in, but I do hear
much reference to Mobile IPv6 in discussions on the development of IP
based mobile /wireless networks.

You asked about applications for IPv6, the only direct answer I can
think of is not new applications, but much improved access to existing
applications.  NAT stops lots of direct communications and hence use
of applications, and in particular interfere with IPsec protocal
usage.  The other big area in application usage is mobility.

The mobility (coupled with low latency, more efficient packet sizes
and packet encryption) is vital feature.  Within the use of mobile
IPv6, devices not on their home report a care-of address (their
temporary network address on the foreign network) to their home agent.
The home agent intercepts and reroutes the first packets of any new
transmissions to the care-of address of the device and also reports
the address-change to the network / device initiating the transfer, so
that further packets go direct and not via the home network.

As someone else said, IPv6 would be a very interesting issue which it
would be nice to have a TLUG technical meeting on.  Well worth getting
used to IPv6, as it is already here and will become dominant.  More so
for people in technical reserach in Japan than elsewhere as the
Japanese Govt has put an emphasis on subsidising IPv6 compatible
projects.

Yours,
Tim
