Traffic Shaping Policies

Traffic shaping policies can be applied to users, firewall rules, web categories, and applications
Default policy can be configured for traffic without a dedicated policy
Policies created for traffic shaping are applied to the specified types and cannot be applied elsewhere.

Example 1: Limiting FTP

Aims to create a policy to limit the bandwidth of FTP applications running on ports 20 and 21
Users must be able to transfer data via FTP without excessive bandwidth consumption by more critical systems
2500 KB/s maximum total FTP bandwidth is the set limit

Example 1: Rule Creation

A new traffic shaping policy named "FTP Limit Rule" is created. This rule is specifically designed to limit the traffic.
The rule sets a priority level for processing (0 - Real-time), so this rule is processed before others.
The limit is set to 2500 KB/s, and the bandwidth usage type is set as "Shared".

Example 1: Applying the Rule

The created rule needs to be applied to a firewall rule.

Example 2: User Guarantee

This example addresses the requirement of guaranteed bandwidth for specific users or groups to a critical business application (cloud application).
The target users are members of a group called "Business Application Users"
1000 KB/s guaranteed bandwidth per user is required

Example 2: Policy Creation

A new policy is created that's user-based and applied to the group.
The guaranteed traffic priority is set to "Business Critical".
The bandwidth usage type is set to "Individual"

Chapter Review

Traffic shaping policies can be applied to users or traffic
Policies can guarantee or limit traffic
Policies have priorities which control the processing order
