This paper introduces the structure and notes of the programming of Windows Coding WDM driver, and finally gives a simple WDM driver and client program source code, hoping to be helpful to everyone. 1. Introduction: Windows 2000, formerly known as Windows NT 5.0, is a new generation of Windows NT 4.0 operating system that inherits the benefits of Windows NT 4.0 and has a number of technical breakthroughs,

Source: Journal of Chongqing University of Posts and Telecommunications A device driver is a software module that deals directly with hardware. In Windows 2000, Microsoft introduced the plug-and-play feature of Windows 9x Based on the driver structure of Windows NT4.0, and introduced a new driver structure (WDM ). WDM simplifies driver development by providing a flexible way, reducing and reducing the num

optical receiving devices. The receiver with a rate of 10gbit/s has been applied, and the 100GBIT/S device has a laboratory sample. Optical amplifiers mainly include fiber amplifiers and semiconductor optical amplifiers (SOA), in which erbium-doped fiber amplifier (EDFA) has been widely used in practical projects, the current research hotspot is bandwidth over 80nm UWB EDFA and distributed Raman fiber amplifiers. Due to its small size, gain width and amplification, switch and other functions, S

to compile paging programs. In this way, the problem arises: how to implement paging. and how to reasonably arrange the paging logic. this topic is the dialog between the list and the page splitter. it is both a dialogue and must be between two subjects. the author designs two objects: Data Representation and paging control. how to organize the call relationship and message mechanism between two subjects is the main content discussed in this articl

Nine, the basic technology and scheme of building broadband metropolitan area NetworkThere are three basic technologies and schemes for building broadband metropolitan Area network: The metropolitan Area Network scheme based on SDH, 10GE-based metropolitan area Network scheme and ATM-based metropolitan Area Network scheme. 1, the metropolitan area network based on SDH technologyThe early SONET/SDH was for traditional telecom services, and it was not suitable for transmitting IP packets. With the

New Optical Switch Technology Now we have an optical switch based on thermal, liquid crystal, acoustics, and Micro-electromechanical MEM: Micro-o-Mechanical. The thermo-Optical Switch uses an aggregation waveguide with heat regulating. The swap is controlled by thin film heating elements published in the polymer stack. When the current passes through the heater, it changes the heat distribution in the waveguide branch area, thus changing the refractive index, so that the optical coupling can be

Waveform Transformation of the baseband signal is called (baseband adjustment) (2) The signal after carrier adjustment is called (band-pass signal), and the carrier modulation is called (band-pass adjustment) (AM, FM, and phase adjustment) 4. Maximum channel capacity There are two factors that limit the transfer rate of the code element on the channel: (1) The channel can pass through the frequency range (bandwidth) (2) signal-to-noise ratio (dB) = 10log10 (S/N) (dB) S: Average Signal Power, N:

The access network technology is still quite common, So I studied the narrow band passive optical network in the access network technology. Here I will share it with you and hope it will be useful to you. ATM-PON has the following technical features: ◆ ATM-PON network topology is star, two-way transmission is generally used dual-fiber Air Division Multiplexing SDM), also based on Single Fiber Wavelength Division Multiplexing WDM.

I have been engaged in the software industry for some years. In the last two years, I have been engaged in personnel surveys and training. I interviewed a large number of people who claimed to be "programmers". Most of them are "proficient in VC ++ and have n YEARS OF C ++ programming experience", "Excellent MFC, ATL, DirectX, winsock, DDK, WDM, DCOM, Corba, Samba ...." And other technologies. Due to my poor knowledge, I cannot be proficient in all th
