there is a huge amount of information on the net. have you done any homework? brief summary, an exchange is a shared fate transport where an ISP can exchange traffic with two or more other participants on the exchange. most of the traffic exchange is done via "peering" with the BGP protocol. Bill Norton has written about peering. Bill Woodcock has built on the old EP.NET data and has a fairly comprehensive set at PCH.NET Current discussion is being held in the OpenIX forums. IXPs are even a part fo the next ITU framework. Care to refine your question a bit? /bill On Thu, Sep 19, 2013 at 08:35:18AM +0330, Shahab Vahabzadeh wrote:
