First, Netem and TC:Netem is a network emulation function module provided by Linux 2.6 and above kernel versions. The function module can be used to simulate complex Internet transmission performance in a well-performing LAN, such as low bandwidth, transmission delay, packet loss and so on. Many distributions of Linux with Linux 2.6 (or more) versions of the kernel feature the kernel, such as Fedora, Ubuntu, Redhat, OpenSuse, CentOS, Debian, and more.TC is a tool in a Linux system with the full

and implements the service quality support module. The specific code is located in the net/sched/directory. In Linux, this function module is called traffic control (TC. First, let's take a look at the general process of sending data packets when the Linux network protocol stack does not have a TC module. 1. Note: The layering is based on Linux implementation and does not strictly abide by the OSI hierarch

Unclassified qdisc example The demand for eth1 Nic egress bandwidth limit is 100 Mbit This can be done using the classless qdisc. TC-s qdisc ls Dev eth1 TC qdisc add Dev eth1 root TBF rate200kbit latency 50 ms burst1540 The bandwidth is limited to 200 kbit, the latency is 50 ms, and the buffer zone is 1540 bytes. Mostly for simple rule restrictions Here is an example of a classified qidsc.

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

Article Title: Use TC in linux to control server traffic. 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. The network environment of a server in the company is too high. When the server is connected to the source server for download, it runs to 400 M-500 M. In order to control the server, we studied

So intend to use C language to achieve, but do not want too much trouble, so think of WIN-
