Micahel, Have you had much experience, having the servers connect directly on to a level-2 device like a FDDI-to Ethernet (e.g. catalyst) connector ? and it security implications ? -Mulugu ========================================================= Mulugu Srinivasarao Tel : 703/904-2013 SprintLink Engineering Fax : 703/904-2292 Sprint, GSD Bldg.

Second: allowing such a customer, or an NSP, to attach web services directly to the FDDI ring at the NAP.
PAIX is doing this. As far as I know the other major interchange provider are not. I am wondering why.
No, Gordon, PAIX IS NOT DOING THIS. I told you quite explicitly that the only hosts connected to the PAIX layer 2 network (GIGAswitch/FDDI, not FDDI ring) are ISP routers, just like all the other IX networks.
*sigh* OK, so PA stands for Palo Alto while I assumed it stood for Pennsylvania...
Anyway, from the point of view of network engineering it makes a lot of sense for the customer machines to be kept off the central exchange media. But from every other point of view, the fact that there is a router between the customer equipment and the layer 2 exchange media is irrelevant as it has no negative impact on anything.
Did I misinterpret Gordon's question as being a higher level question about which XP's allow customer servers to have high-speed access to the XP? Said high-speed access could just as easily be a Gigaswitch/FDDI behind the ISP's router.
