I'm on an assignment and its asking for a network speed of 1gbps for at least 60 PCs but to be scaled to 120 devices/PCs I think the cisco 4461 router is sufficient (I'm using it as a core router) and I'm using 3 more cisco routers 4451 connected to the previously mentioned and each one has a switch with 20 devices on each one. I'm just unsure of how I could see if the Scalability would work or if there is a process in how to test or calculate
very much apperciated for any suggestions
