Click comes with many elements that implement diffserv-like QoS, including
hard bandwidth guarantees (within a single router). The TOCS paper, for
example, demonstrates a QoS configuration. But we have not looked into
intserv. Remember that truly "hard" QoS requires cooperation from *all
routers along a path*. Click can't help you there unless you are dealing
with a path that you can completely administer yourself.
