v Question and Answer

v Bandwidth management is the process of

measuring and controlling the communications

(traffic, packets) on a network link to avoid

network congestion and poor performance of the

network.

v Bandwidth management is measured in bits

per second (bit/s) or bytes per second (B/s).

What is Bandwidth management?

Why we need to manage bandwidth in our network?

v Control traffic bandwidth of users

v Avoid congestion in the networks

v Allocate resource for other important use (Voice

Videos …)

v Save cost

How to Control Bandwidth on Linux (CentOS7)?v We have many tools and methods for limiting rate on

Linux OS (Wonder shaper, Traffic Control (TC), Fire QOS

…).

v FireHOL is a language for builds secure stateful

firewalls from easy to understand, human-readable

configurations.

v FireQOS is a program which sets up traffic shaping

from an easy-to-understand and flexible configuration

file.
