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. |
But when tc prints the rate, it uses following :
1Mbit = 1024 Kbit = 1024 * 1024 bps => bit/s |
