This article mainly introduces "specific application examples of flow control in Linux system". In daily operation, I believe that many people have doubts about the specific application examples of flow control in Linux system. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of "specific application examples of flow control in Linux system". Next, please follow the editor to study!

Application example of Linux flow Control

Suppose an enterprise is facing a complex network environment. In this environment, both the local area network of 100Mb and the wireless link network of microwave or 802.11 are included, and the network topology is shown in figure 3. In such an environment, to ensure the flow of business data and achieve Linux flow control, it is necessary to control the transmission and business services of each local area network.

The system uses Linux 2.2.14 kernel to support QoS. First, you need to recompile the kernel. Run make config with the following settings:

EXPERIMENTAL _ OPTIONS = yClass Based Queueing (CBQ) = yQoS and/or fair queueing = yCBQ packet scheduler = yRate estimator= y Packet classifier API = y

Compile and generate a new kernel:

# make dep#make clean#make bzImage

In the Linux operating system, the flow controller (TC) sets up a queue at the output port to control the flow. The way of Linux flow control is based on the destination IP address, the network number and port number of the destination subnet, or based on the source IP address, the network number and port number of the source subnet.

The basic functional modules of Linux traffic controller TC are queue, classification and filter. Queues supported in the Linux kernel are Class Based Queue, Token Bucket Flow, CSZ, First In First Out, Priority, TEQL, SFQ, ATM, RED. The queues and classifications discussed here are based on CBQ (Class Based Queue), and the filters are based on U32 and FW.

At this point, the study of "specific application examples of flow control in Linux system" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
