# Chapter 9. Queueing Disciplines for Bandwidth Management

Now, when I discovered this, it really blew me away. Linux 2.2/2.4 comes with everything to manage bandwidth in ways comparable to high-end dedicated bandwidth management systems.

Linux even goes far beyond what Frame and ATM provide.

Just to prevent confusion, tc uses the following rules for bandwith specification:

    mbps = 1024 kbps = 1024 * 1024 bps => byte/s
    mbit = 1024 kbit => kilo bit/s.
    mb = 1024 kb = 1024 * 1024 b => byte
    mbit = 1024 kbit => kilo bit.

Internally, the number is stored in bps and b.

But when tc prints the rate, it uses following :

    1Mbit = 1024 Kbit = 1024 * 1024 bps => bit/s
