I've been reading up on QoS and wanted to do some testing with it but have run up against a problem on scale.
I wanted to learn how to implement it so I was going to implement both an IntServ and DiffServ model in a small home network but I'm not clear on if this is possible for such a small application. In the end, my goal is to figure out what is best for a small LAN with a few dozen voice, video, and data apps that will send locally as well as outside the LAN.
I've read that QoS (e.g. IntServ) requires several functions on routers and switches along the path like admission control, classification, policing, queuing and scheduling. But say I have all this gear, and one of the hops in the network is done over radio and this radio may have to travel very long distances. Does QoS still work then?
Generally you can test all QoS features in your lab no problem, you'll just need to make sure that the platforms and IOSs that you are using supports the intended feature, i'll recommend that you use Cisco Feature Navigator, as for the radio connectivity, i don't know what kind of radio connectivity you are talking about, but generally they are characterized with low speeds and high delay which may impact your voice and video traffic, but QoS is functional and can circumvent most of your problems.
