On at least two occasions that I can document, I've been asked to opine for a large house consultancy on how such capacity tracking could be achieved, while the meat is still fresh in the freezer case. One of them actually asked about a dynamic predictor capability. What's the use, when plug-in inventory for the higher bandwidth denominations is always at least a month to three months in arrears, if you're lucky? The johnny-come-lately backbone providers have a better handle on inventory. All they have to do is count the lambdas (and the cross-connect ports behind them) that are busy or idle. The incumbents, on the other hand, have multiple overlays of used, retiring and emerging platforms that are at best unwieldy to track, even if they tried. Fragmentation between divisions based on each carrier's disparate service areas doesn't help their cause, either, despite the existence of sophisticated trunk assignment databases and tracking tools. Somehow those don't seem to "see" beyond their individual purviews. The glitch is often found in the amount of manual intervention that must occur on the parts of facilities engineers who design customer networks, as opposed to those processes being fully automated. Just keeping track of the number of plug-in unit$ in inventory can be a bear.
