What is the difference between throttling network and network tuning?

Doesn't both means to send with the maximum possible bandwidth?

Check out this article on Policing traffic versus Shaping traffic.


Cisco: Policing vs. Shaping

Policing (aka throttling) is done by dropping traffic when it exceeds the configured rate. Network Tuning (aka shaping, QoS, etc.) implements queues to hold traffic that exceeds configured rates. (this can include prioritization of different types/classes of traffic. eg. VoIP getting high priority than web browsing.)

  • I saw this diagram elsewhere (can't remember where) when I was trying to get a basic handle on QoS. Your explanation summarizes a lengthy and wandering document very well.
