RE: Optical Link Interface
Bilel,
I might not have worded my response exactly as John did (being the nice
guy that I am), but I agree with his answers.
In particular, you continue to talk about "unnecessary
LMP baggage", or "complexity", but cannot describe
what it is.

- Andre,
- 2 comments on you statistics, then a proposal to progress:
- 1. The stats are not that significant, since there was no "last call" period announced in advance to gauge community interest.
- [John Drake]
- This is silly. Who else would you like to hear from?
- 2. I do not think IETF uses company affiliation when measuring consensus. If it did, then the fact that 3 from Nortel are supporting NTIP, is an indication that there is an immediate need for NTIP given Nortel is a key player in this space.
- [John Drake]
- The fact that you perceive yourself to be a key player shouldn't a priori give your opinion any additional weight
- ------
- All,
- Now to focus the discussion back on the OLI solutions (NTIP or LMP-WDM, or a merged version),
- - There is consensus on a single protocol which I respect.
- - Key distinctions between NTIP and WDM-LMP:
- 1. WDM-LMP assumes that LMP is a priority, people will implement LMP, hence WDM-LMP is a natural extension. The issues here are:
- (a) this assumption is not accurate, the functions of NTIP (or WDM-LMP) are more urgent than LMP
- [John Drake]
- What is the basis for this assertion? When we started the LMP-WDM work we asked you to work on it with us
- and you refused, citing lack of need.
-
- (b) there is significant baggage to be carried from LMP down to the WDM-LMP
- [John Drake]
- You've made this assertion inumerable times, and have been asked inumerable times to enumerate what this
- excess baggage is. You have yet to do so.
- 2. WDM-LMP assumes a peer model between the OXC and the WDM system. The issue:
- - this model doesn't reflect the reality that OXC and WDM are two different devices - the OXC-WDM relationship is client-server one.
- [John Drake]
- This is an assertion. Some of the co-authors of the LMP WDM draft work for WDM vendors and they're happy with
- the peer relationship between the two devices
- I suggest merging the two proposals as follows:
- - remove unnecessary LMP baggage
- [John Drake]
- Once again, this would be what?
- - adopt a client-server model
- [John Drake]
- No
- - allow for TCP as the transport
- [John Drake]
- No one but you and your co-authors think that this is either necessary or desirable
-
- - clarify a simplified autodiscovery mechanism
- Bilel.

- From my count on the mailing list we have the following results so far:
- LMP-WDM: 8
- NTIP: 3 (All from Nortel)
- Agnostic: 1
- And then there are the other 16 co-authors of LMP-WDM who haven't posted
- (perhaps because they don't think they have any new points to add).
