Quality of Service, Hierarchical Token Bucket HTB

Quality of Service

Traffic control in a network can be achieved by Quality of Service (QoS) algorithms, which involves guiding the packets based on some predefined rules. Traffic control classifies packets and places them in individual flows or classes. It can then police by limiting the number of packets transmitted and/or schedule the packets in different order of priority for transmission.

The QoS algorithms in the router can apply prioritization rules on traffic which are passing through the router. However, the traffic will need to be prioritized at every hop router until it reaches its destination to ensure good quality of service. This can be achieved by ensuring that the TOS octet in IP header is set appropriately. Every hop router can prioritize traffic based on the TOS octet value in the packet’s IP Header.

9.1 Hierarchical Token Bucket (HTB)

HTB is a classful queuing algorithm which provides rate limiting, guaranteed bandwidth and prioritization of the traffic. HTB ensures that the amount of service provided to each class is at least the minimum of the amount it requests and the amount assigned to it. When a class requests less than the amount assigned, the remaining (excess) bandwidth is distributed to other classes which request service and which have highest priority.

To enable this feature, the administrator can configure the total interface bandwidth and different classes with the total bandwidth shared among them. Subsequently filters need to be configured to match the traffic to flow through the different classes.

9.1.1 Class Configuration

The administrator should configure a Root Node first, by specifying the interface bandwidth (upstream link bandwidth) and the default class to be used for unclassified traffic. Subsequently, Class Nodes can be added and the interface bandwidth can be distributed among these classes.

Select QoS → HTB Configuration to enter the HTB QoS Configuration. Select Node as Root to configure the HTB Root Settings.
