I feel slightly embarrassed to be asking this but I have to know.
I have a project where the project team has asked me to build a flat network. There will be approximately 10,000 hosts.
Half of those 10,000 hosts will be very low traffic (former 9600 baud serial connections migrated to ethernet). I have NO ability to run packet captures since this is a "proposed" solution.
I am trying to convince the team that even low traffic ethernet interfaces are going create much more arp/dns/whatever traffic than they are thinking they will. The chatter will be enormous.
Can anyone help me with the argument? I have already sent an "CYA" email to my boss saying that I fully expect this network to crash.
The topology will be such that I have about 13 sites spread around a single mode fiber optic ring.
My problem is in convincing this team that the arp traffic alone on a 10,000 node network is going to create a ton of latency for the entire network.
