Thats an average over 30 day periods. How is this converted to peak hour load projections? We have SNMP link utilizations in 15 minute increments that could be averaged over an hour to get a rough conversion factor. We could probably provide access to this data (Merit should already have access to it, I think) or if not provide the conversion factor if asked. In any case, this is John's topic, but I'm quite interested in both the bottom line numbers and the method (so we have a better idea how much to trust the bottom line).
