Currently, three most popular IP transmission technologies are available: IP over ATM, IP over SDH, and IP over WDM. All three IP transfer technologies will play their own roles in different periods of telecommunication network development and different parts of the network. The three will coexist and complement each other. However, from a future-oriented perspective, IP over WDM will be the most vital tech

observe. When the system starts, the root bus driver is loaded, and then the driver device mounted on the Root bus is found. If a PCI device is found, the PDO of the PCI device is loaded and the appropriate fdo is searched for loading. For example, a USB adapter is used as a PCI device and loaded with PDO and fdo. Physical Device objects are generally created by bus drivers. WDM enables people to focus more on fdo. One or more

WDM (Win32 Driver Model), A Win32 driver model, is a brand new driver model pushed by Microsoft. It aims to simplify the development of the driver in a flexible way, reduce and reduce the number and complexity of necessary drivers on the basis of implementing support for new hardware. At present, the main tool used for WDM driver development is the DDK (driver development kit) provided by Microsoft, which c

Broadband access network development is very rapid, but also led to the rapid development of WDM-PON technology, may be many people do not know the development of WDM-PON technology and the future direction, there is no relationship, after reading this article you must have a lot of GAINS, I hope this article will teach you more things. The Passive Optical Network PON technology has received great attention

Wireless Broadband Access Network is more commonly used, so I studied the WDM-PON technology will become a new direction of wireless broadband access network, here to share with you, I hope to be useful to everyone. The Passive Optical Network PON technology has received great attention in the industry in the past two years. Due to its superior performance in wireless broadband access networks and its advantages in resource utilization, FTTx technolog

The key to seamless combination of GMPLS--IP and WDM In recent years, with the rapid development of Internet technology, the traffic of data services represented by IP has rapidly increased and has gradually become the mainstream of network services. However, the existing transmission network is voice optimized. to enable it to carry data services efficiently, new technologies are required.To transmit data services, the existing transmission network a

1) DDK and wdk DDK is based on the WDM driver model, while wdk is based on the WDF driver model. The biggest difference between the WDM Driver Model and the WDF driver model is: 1) the WDF driver framework encapsulates WDM once. The WDF framework is like the base class in C ++, and the model, Io model, PNP, and power management model in this base class; some

Application of single channel 10G Wavelength Division transmission SystemInternet has become an indispensable tool for Gaga households, because the network era, People's happiness index is more and more high, the rate of Internet broadband is more and more high, the trend determines the network needs to be reformed. In the early stage of the first set of fiber-optic networks, over time fiber resources have been very scarce, in this context, the emergence of
