Hi all,

I am doing the final edits to the terminology draft, and I would need 
answers to the following questions raised by the IESG and Thierry Ernst in 
a separate email.

Jukka


1) What would be the definition of a subnet? Thierry thought one should be 
added.


2) The definition of source route?

     Source Route
       A source route from node A to node B is an ordered list of IP
       addresses, starting with the IP address of node A and ending with
       the IP address of the node B. Between A and B, the source route
       includes an ordered list of all the intermediate hops between A
       and B, as well as the interface index of the interface through
       which the packet should be transmitted to reach the next hop.

Allison: This is a stricter definition of Source Route than is usual.
Normally SR includes ("Loose SR") the possibility to omit intermediate
hops.  Consider clarifying.

[JM]: Suggestion to remove "all the", and add at the end "The list of 
intermediate hops might not include all visited nodes, some hops might 
be omitted for a reason or another."


3) Is the definition of "link" sufficient? Does it need to be very
detailed? There was this email quite some time ago:

<SNIP>

Hi,

I have a question about the definition of "link" in

draft-ietf-seamoby-mobility-terminology-04.txt

It is said:

"A communication facility or physical medium that can sustain data
communications between multiple network nodes, such as an
Ethernet (simple or bridged). A link is the layer immediately
below IP."

As I undestand, the definition of link is not directly related to an
IPv6 link.
For example, consider the following example:

One ethernet link where a router advertises a single IPv6 prefix, and an
802.11b access point connected to this ethernet link as illustrated here:


         AR
   ____ |__________________
                |                         |
             AP                     Fixed node
                         MN2
 MN1

In this situation, is it right to say that :
    - there are 2 links
and
    - there is one IPv6 link
?

Thanks

Regards,
Nicolas

[JM]: (don't know how the figure was meant to be formatted...) Isn't an
802.11b AP just a wireless bridge between the AR/FN and MN1, and, thus,
not its own link? Still, you could say there are two links and one "IPv6 
link", for example. Comments?


4) Do we need an index of terms (Appendix B)?
