inflexible, the demand analysts always want to understand all the requirements of users. After understanding the requirements, we assume that all the requirements are understood and then design and code them, as a result, the software cannot handle new attributes flexibly in the future. To solve this problem, we believe that using user configuration and templates can not only reduce the time required for software implementation, but also ensure maxim

Broadband Access Network is currently the most common access method, so I have studied the design concepts and standards of broadband access networks. I would like to share with you here, hoping to be useful to you. A Broadband Access Network is a transmission medium. It establishes multiple independent network carrier

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. As a system, its security should be carefully considered when planning the network topology to formulate security policies. After th

This series of blog mainly on the background of the game to introduce 3D PvP Network game Common Development technology and C + + advanced programming skills, with this knowledge, you can develop small and medium-sized game projects or 3D industrial simulation projects.The author will be divided into the following three sections to introduce to you (daily update):1, the realization of the basic communication framework, including the game needs analysi

Turn from: http://blog.csdn.net/shreck66/article/details/49618331 1. Why application layer buffer is necessary in non-blocking network programming The central idea of non-blocking I/O (which is understood here as non-blocking I/O plus t/o multiplexing) is to avoid blocking the current thread on I/O system calls, so that our I/O threads block only on I/O multiplexing functions (epoll_wait or Poll,select) Enable it to serve more connection sockets so h

Features of wireless network design for integrated networks Wired and wireless Integrated Access Solution The wired and wireless Integrated Access solution is the most typical application of Fit AP for wireless controllers. As the center for Wireless Data Control and forwarding, the wireless controllers are placed in the Central Data Center of the Internet, wireless access points are placed in office build

Like operating a local computer, you need to provide each network user with their own hard disk space, the user can log in after their own space management. Management is multifaceted, first users should be able to see all the content under their own folders, in addition to provide multi-level folder directory support. The following examples include many of the features of the online hard drive, which will be introduced in a step-by-step way. First,
