3) As time passes, more providers either understand the benefits of peering at an exchange point versus paying ${UPSTREAM} to provide transit for all of their traffic, or their traffic levels grow to the point (see point 1) where peering at ${EXCHANGE} begins to make financial sense. Most providers lack the levels of traffic or the geographic footprint to peer with the big guys (UUNET, Sprint, AT&T, CW, Genuity, etc), who typically build private interconnections with each other in multiple geographically diverse areas. Private interconnects are normally not cost effective for service providers who don't satisfy those criteria, so for them, peering at exchange points is more financially/technically attractive.
Is there a need for additional IXs or are there too many today and some should be consolidated or shut down altogether? If there is a need for new IXs, where do you put them? Who decides where to build a new IX and how do you get service providers to show up there once it is built? Thanks. __________________________________________________ Do You Yahoo!? Yahoo!
