HTBQOS traffic quality control for ROS

Article title: ROS uses HTBQOS for traffic quality control. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Layered token bucket HTB

HTB (Hierarchical Token Bucket) is a classful queuing discipline that is useful

Applying different handling for different kinds of traffic. Generally, we can set only

One queue for an interface, but in RouterOS queues are attached to the main

Hierarchical Token Bucket (HTB) and thus have some properties derived from that

Parent queue. For example, we can set a maximum data rate for a workgroup and

Then distriunt that amount of traffic between the members of that workgroup.

HTB is a classic theory used for traffic classification control. Generally, only one interface is used for traffic control, but ROS uses the HTB theory,

For example, you can first limit the traffic of a working group and then further segment the traffic within the working group. Traffic control is complicated.

God thinks.

Each class in the hierarchy can prioritize and shape traffic. There are 2 main

Parameters in RouterOS:

* Limit-at-data rate that is guaranteed to a class (CIR)

* Max-limit-maximal data rate that is allowed for a class to reach (MIR)

Two main parameters:

Limit-at: stable rate

Max-limit: maximum rate

* CIR (Committed Information Rate)-the guaranteed data rate. It means that traffic

Rate, not exceeding this value shoshould always be delivered

* MIR (Maximal Information Rate)-the maximal data rate router will provide

CIR: minimum guaranteed speed. The rate not higher than this is always allowed

MIR: maximum rate
