You need at least a pair of “switches”, and you really need more. But there are multiple options for what you buy to do switching with for the lab, and those choices impact the topology you end up ...

Mathematicians proved in the early 1990s that randomly connecting routers produces the most efficient, resilient network topology. It took AWS roughly 30 years to turn that result into production ...

Have any of you Arsians heard of something called a 'router-bus' network topology? If you have, could you please share your knowledge? -- -- Diagrams would be appreciated as well. I've been hitting up ...
