[Blog recommendations] Analysis of the principles of the Linux TC (Traffic Control) Framework This blog post is from the Bkjia blog dog250 blogger. If you have any questions, go to the blog homepage for an interactive discussion!Blog: http://dog250.blog.51cto.com/2466061/1568267 Recently, my work is more or less related to Linux throttling. Since I learned about TC a few years ago and

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)

service (ToS.RedRed is short for Random Early Detection (Random Early Detection. If this qdisc is used, when the bandwidth usage is close to the specified bandwidth, the system will randomly discard some data packets. It is ideal for high-bandwidth applications.SFQSFQ is short for Stochastic fairness queueing. It sorts the traffic by session (Session-corresponding to each TCP connection or UDP stream) and sends packets for each session cyclically.TBFTBF is short for token bucket filter and is s

The corresponding will produce a table under this username.In a formal environment, because the use of ADM, Su, can be key three username, so under these three username will generate the c

Deleting the TC Filter Using the filter generation rules will clear all filters.The correct method is mentioned on the mail list.Unlike the class, you can simply replace add in the TC command with Del if you want to delete it after adding it. If the class is repeated, it will be prompted like an error occurs when adding a route.But the filters are different. Filters with the same rules can be continuously a

Yesterday there was a need to have a bandwidth limit on a process, learning CGROUP+TCThe approximate process is as followsFirst, TC.TC the approximate process is as follows: Root is qdisc---category that is, root there will be a lot of classification we call him class, which defines the rules, that is, the bandwidth limit of how much----filter which is used to specify which categoryCgroupUnderstanding as a container, doing system resource control Yum Install Libcgroup 2.

According to many documents of TC, I have also compiled a configuration record. In actual use, the effect is good. I would like to share it with you for your reference.Environment: the local area network is not large enough to support more than 40 machines. Nat Internet sharing (Intranet: eth0 Internet: eth2)CBQ uses the idle time of hardware to calculate the queue. The hardware is different and the effect is different. It is better to use htb for a l

　　[It168]As we all know, at the beginning of the Internet, colleges and research institutions communicate with each other, and there is no consideration or design for network traffic control. The principle of IP protocol is to serve all data streams as well as possible, different data streams are equal. However, many years of practice show that this principle is not the most ideal, and some data streams should be taken special care of. For example, interactive data streams with remote logon shou

TC for flow control, and give several representative examples. I. Related Concepts Packet packets from the input network card (portal) received, through the routing of the lookup, to determine whether it is sent to the machine, or need to forward. If it is sent to the local, directly forward to the upper level of the protocol, such as TCP, if it is forwarded, will be issued from the Output network card (export). The control of network traffic usually

TC is the abbreviation of Linux traffic control, the principle is that when the protocol stack out of the packet, through the Qdisc (Queue discipline) and filter mechanism to the different rules of the definition of the exile to the different class Qdisc (for classful Qdisc is so, for classless Qdisc only one root qdisc). There are a lot of data on TC on the Internet, this article does not discuss the use o

A: Overview:The flow controller (TC) in a Linux system is mainly to establish a queue at the output port for flow control.TC is a tool that can classify a packet according to its characteristics, and can provide different bandwidths for various types of data, thus controlling their transmission speed. TC is part of the IPROUTE2, integrated in the 2.2 and above versions of the kernel, and can also work with
