I hate following up on my own message, so I'm following up on this. A
point just raised privately was that *IF* you need the buffers you could
just OSM the ports under stress [say the ones dedicated to the 1 or 2
expensive WAN links you may want to run near their top]. Considering a 4
port GE-WAN OSM is $800 on Ebay, I don't see how its even a pricing
consideration.
