TC Introduction
In Linux, TC has two kinds of control methods CBQ and HTB. HTB is designed to replace the CBQ. It is a hierarchical filtering framework.
The TC consists of three basic constituent blocks:
Queue rules Qdisc (queueing discipline), Class (classes), and classifiers (classifiers)

I. Introduction to TC principles
In Linux, the traffic controller Tc (Traffic Control) is used to control traffic in the Linux kernel. It establishes a queue at the output port to control traffic.
Shows the basic principles of Linux traffic control.

I. INTRODUCTION of TC Principle The Traffic controller TC (traffic control) in the Linux operating system is used for the traffic control of the Linux kernel, mainly by establishing a queue at the output port for traffic control. The fundamentals of Linux traffic control are as shown. When the receiving packet comes in from the input interface (inputs Interface), the traffic limit (ingress policing)
packets through a network interface, it needs to add the packets to the queue according to the qdisc (queuing rule) configured for this interface. Then, the kernel extracts data packets from qdisc as much as possible and delivers them to the Network Adapter Driver Module.The simplest qdisc is pfifo, which does not process any incoming data packets. data packets are first-in-first-out in the queue. However, it will save packets that cannot be processe
, the form "major:0", or "major:" For example, queue 1:0 can be abbreviated to 1:. It is important to note that major must be unique in all queues of a network adapter. For a category, the major must be the same as the major of its parent or parent queue, and minor must be unique within a queue (since the category must be included in a queue). For example, if queue 2: contains two categories, the handles of these two categories must be 2:x, and their

Tc requires kernel 2.4.18 or above, so upgrade is not enough
Tc can only control the speed at which packets are sent by the Network Adapter. Therefore, the upload speed must be limited to eth0.

Data Packet Classification and scheduling-another explanation of Linux TC-linuxtcIf you understand the Linux TC framework from the perspective of layered recursion, it is easy to classify queues into class queues and class-free queues. In this perspective, the status of a queue is equal to that of a queue. But in fact, there is a hierarchical relationship between them. The reason for dividing it into a clas

TC IntroductionIn Linux, TC has two kinds of control methods CBQ and HTB. HTB is designed to replace CBQ. HTB is more flexible than CBQ, but CPU overhead is also greater, and usually high-speed links use CBQ, generally HTB used more broadly. HTB's rules are essentially a tree-like structure, consisting of three basic constituent blocks: The queue specifies Qdisc (queueing discipline), classes (Class), and C
