I guess I see them as two functions which may or may not be connected. The route collector does the work of peering with the participants. An exchange operator can interact with a route collector as if it were a standard router; there is no need for any interface other than the cli (or other standard interface) for the trouble shooting function. The looking glass can be tied to the same information source, but its primary function is to present that data. In a lot of cases the interface used for that isn't different from the interface used by the exchange operator, so the two are strongly tied. They can be weakly tied, though, as the looking glass might use a different information source (say, a participant's router) or may have filters which limit what data can be presented to the looking glass's user base. Does that match your sense of the functional difference? regards, Ted Hardie
