What is tc qdisc?
Tc is used to configure Traffic Control in the Linux kernel. DROPPING Traffic exceeding a set bandwidth may also be dropped forthwith, both on ingress and on egress. Processing of traffic is controlled by three kinds of objects: qdiscs, classes and filters.
What is Linux qdisc?
qdisc. Simply put, a qdisc is a scheduler (Section 3.2). Other qdiscs available under Linux will rearrange the packets entering the scheduler’s queue in accordance with that scheduler’s rules. The qdisc is the major building block on which all of Linux traffic control is built, and is also called a queuing discipline.
What kind of traffic is included in traffic classification?
In some networks, this definition can include such traffic as non-local VoIP (for example, Skype) or video streaming services to protect the market for the ‘in-house’ services of the same type. In these cases, traffic classification mechanisms identify this traffic, allowing the network operator to either block this traffic…
How to configure network traffic classification in MQC?
To configure network traffic classification, you use the Modular Quality of Service Command-Line Interface (MQC). The MQC is a CLI structure that allows you to complete the following tasks: Specify the matching criteria used to define a traffic class. Create a traffic policy (policy map).
Why are packets classified in different traffic classes?
Each resulting traffic class can be treated differently in order to differentiate the service implied for the data generator or consumer. Packets are classified to be differently processed by the network scheduler.
Which is the best definition of traffic control?
Traffic control is the term given to the entire packet queuing subsystem in a network or network device. Traffic control consists of several distinct operations. Classifying is a mechanism by which to identify packets and place them in individual flows or classes.
