Title: RE: TCP Connection Identifiers in IPv6

This can be true in IPv4 as well...  for example,
if the IPv4 stack allows multiple interfaces to have
the same "autonet" (169.254...) addresses, which
are roughly equivalent to link-local addresses.

Subject: TCP Connection Identifiers in IPv6

Hi,

In IPv4 a TCP connection was uniquely distinguished with the help of  the 4 tuple.  Does this hold good with IPv6? I can think of the following scenario caused by scoping, where such a identification might fail.

In IPv6 scenario, if a  node with multiple links having same link local addresses on both the interfaces exists, then it is possible that the 4 tuple is no longer sufficient to determine a connection uniquely. There has to be an interface identifier added as the 5th element to now distinguish across connections.

Any comments/suggestions?

Thanks,
Narsi
