3. definition of an IXP -----------------------
It was generally felt that it is difficult to define an IXP, but that the following refined definition could be used as a starting point:
Three or more ASes and thee or more separate entities attached to a LAN (a common layer 2 infrastructure) for the purpose of peering and more are welcome to join.
My way of writing it, would be: "Three or more ASes owned/managed by 3 or more separate entities attached to a common layer 2 infrastructure, for the purpose of peering." - I dont see an IXP necessarily as a LAN. An IXP can be distributed geographically, so the IXP infrastructure can really be called a WAN. - The same way we dont refer what kind of peering is done (BGPv4, normally) i think we shouldnt limit the definition introducing the "more are welcome to join" part... Of course i want all IXPs to grow (regarding the number of peers) and especially the one i manage :-), but i feel this "welcome call" is more just another "political" issue.
