Depends on if he wants to police or shape. To police you don't need much of a buffer, and it's a very hard cutoff. To shape (much better user experience), he'll need something like RED, WRED, codel/fq_codel and deeper buffers.

Normally switches don't have the proper buffer depth for that kind of thing at scale, unless using those super high throughput, very large buffer data center oriented ASIC designs.
