RE: Re: Some thoughts on policy and governance issues with respect to open lightpath exchange points

["Wilson, Rodney" <rwilson@xxxxxxxxx>]

This is shaping up to be quite an interesting discussion. But our time during the Internet2 meeting is brief. The definitions are important as we need to reach some common terminologies which are the handles we grab as we carry on to the discussion Bill has proposed. 

I suggest we use this forum to get the definition discussions substantially dealt with prior to meeting face to face. If there are strongly held diametrically opposed definitions, we have more worries than addressing optical network allocation, management and governance. If on the other hand it's a matter of semantics let's move quickly on.

Building on Jerry's start, is this the lexicon we need to define. Or are there additional candidates?

In the light of Jerry's search for definitions, here are my comments, 
some perhaps clarifying some no doubt muddying.

We should probably distinguish "exchange" from "exchange point".  The 
former can have its own internal topology whereas the latter tends to 
imply a single point (place or locus) of operation.  With this 
distinction, the term "distributed exchange" makes sense but 
"distributed exchange point" doesn't (it is an oxymoron since a point 
can't be distributed, can it?)

The goal not GOLE :-)  of an exchange point is to provide a capability 
for other entities (usually networks) to exchange traffic where the 
interaction between the participants may occur at different protocol layers
