I'm fairly new to network design and I was wondering if someone could help clarify a couple of things regarding traffic prioritisation on a LAN.
Some background: I'm designing a network that will have a number of PCs connected via Ethernet, a number of wireless access points, server(s) storing multimedia content and server(s) for file storage. Ideally certain users' traffic would have a higher priority than others and traffic to/from the media server would have a higher priority as well.
I was thinking of using DiffServ prioritisation to avoid having to reset the priority field at each switch and configuring switches to automatically prioritise traffic to/from the MAC addresses of priority users and to/from the IP address of the media server.
Is this an appropriate way to approach the problem. Would using separate VLANs and prioritising those be a better solution?
