Traffic Shaping - Network+
Traffic
shaping, or packet shaping, is a network bandwidth management technique
that controls data flow into and out of a network. It ensures that critical applications and time-sensitive data are delivered without delay.
Here's
how traffic shaping works:
- Categorize traffic: Traffic is categorized according to network policies.
- Queue traffic: Traffic that exceeds the average bit rate is buffered in a queue.
- Delay packets: The transmission of less important packets is slowed so priority applications can be delivered without delay.
Traffic
shaping is important because:
- It helps ensure the performance of critical applications
- It helps deliver time-sensitive data
- It helps defend against bandwidth-abusing DDoS attacks
- It's an essential requirement for a network firewall
