Network infrastructure of large networks
Hi,
Currently, is it possible to run a large network with Free Software?
If a large organization would like to run only Free Software, how would their network infrastructure be?
Which devices and software should they use to replace their proprietary state-of-the-art network appliances?
I mean stackable 48-port switches which have optical uplinks, high-performance routers with optical and other interfaces, powerful multi-feature firewalls, and so on.
Which existing hardware and software would you use?
Let's think we are millionaires.
Thank you.
