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.
