Perry> Perry As to how much of the traffic is local, about half of the people I know at least check email from home. Some are "weekend and evening telecommuters", making quite extensive use of "local connectivity". How this compares to the generic web surfing, I can't say. The CAIDA and NLANR folks say that http traffic is the most significant portion of today's Internet. Perhaps someone who is actually running a local exchange can report on how much traffic they are carrying that is now not being sent to a MAE-equivalent? I think that actual experience and hard data will surprise us all. --tep
