Hi Jeff, Glad to see you jump into this.. Would you feel comfortable is sharing what Model Image Stream will do the following:-
be able to handle full bgp feeds from multiple providers ( 2gig Ram ?) and be able to handle 300 - to a GIG of traffic ? Rough cost of unit will be great to know as well. (Gig E feeds, copper & Fiber). And How Stable is the Imagestream in running this type of a configuration. Regards.
