RE: [NSIS] new GIMPS version



Hi Takako,

The phrasing is sloppy (my fault). 

Case 1 could better say "... the RAO is relevant to NSIS but
not the specific node, but the IP layer is unable to recognise
whether it needs to be passed to GIMPS for further processing
or whether the packet should be forwarded just like a normal
IP datagram."

(In this case, because the RAO is not relevant to the specific
node, the GIMPS processing is to do whatever should have
been done to a normal datagram. In some implementations,
GIMPS would not be invoked at all here.)

Case 2 is different because the RAO *is* associated with a set
of signaling applications, some of which are processed on the
node (but not this specific one). 

Section 8.4 is also relevant here.

Hope this helps,

robert h.
