Article Title: Linux Network Device Driver Programming. 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. This article only discusses the general Writing of network device drivers. Th
Reprinted from: http://my.csdn.net/weiqing1981127A Network Device Driven Fundamentals1. Basic Theory of EthernetEthernet is a kind of LAN, it uses the carrier to listen to multi-channel access and Collision detection technology (CSMA/CD), and at the rate of 10m/s run on a variety of types of cable, commonly used network card chip has DM9000, DM9161, CS8900 chip.T
One of the biggest features of Linux is its network stack. It was originally originated from the BSD network stack and has a very clean set of interfaces, which are well organized. Its interfaces range from protocol-independent layers (such as general Socket Layer interfaces or device layers) to specific layers of various net
Network security platform vendors often need to use a special technology, that is, Bypass. So what is Bypass and how is the Bypass device implemented? Next I will give a brief introduction and description of the Bypass technology. 1. What is Bypass. As you know, network security devices are generally used between two or more networks, such as between the Intranet
-device equipment is mainly as a sensor node, the collected data information, as well as the usual control information (such as maintaining a connected heartbeat packet, command control packets, etc.) sent to the Router/coordinator device. The following address: node/end node/sensor node, all refer to end-device; routing/relaying, all refer to Router; Coordinator
generation network. There are two main ways to implement ROADM: broadcast, choice, and cross-use. The broadcast/select-type ROADM device consists of tunable filters, wavelength receivers, and other devices. The demultiplexing, crossover, and multiplexing ROADM devices generally use wavelength division multiplexing and demultiplexing, coupled with controllable optical switches [2]. With the rapid developmen

Fiber access network devices are still commonly used. So I have studied the functions of the next-generation Metro optical access network devices. I would like to share these functions with you here. I hope they will be useful to you. The ADM622 product series provides carrier-level devices with low costs and flexible services. The PM5337ADM622 and PM5338 ADM 622 PDH Optical Fiber access devices of PMC-siel
Many virtual network devices are used in the implementation of OpenStack virtualization network, which is the basis of understanding the implementation of OpenStack virtual network, this article simply introduces these virtual network devices.TUN/TAP EquipmentThe TUN/TAP device
If you have installed the VLAN kernel module and the Administrative Tools Vconfig,tap/tun Device Management tool TUNCTL, you can set up the relevant network device using the following command: Create Bridge:brctl ADDBR [Bridge NAME] Delete Bridge:brctl Delbr [Bridge NAME] Attach device to Bridge:brctl
When the main performance of a LAN cannot meet the new application requirements of an enterprise, you must consider upgrading the network. During the upgrade, you should analyze the problems to be solved based on the requirements of network applications, especially the upgrade of switch hardware devices. This article will discuss this issue with you. Upgrade network
When you learn about linux network devices, you may encounter the problem of loading and detaching. Here we list a variety of commands for loading and detaching. Here we will share some of them with you. Hope to help you.
