Handle bare devices on Unix systems: 1. What is a bare device? A bare device, also called a raw partition, is a special character device that is not formatted and not read by Unix through a file system. It is read and written by the application. It is not buffered by the file system. 2. How to identify bare devices? In the Unix/dev directory, there are many files, including two categories: character device

Softswitch devices are still commonly used, so I have studied the networking scheme of softswitch devices. I will share it with you here, hoping it will be useful to you. For the SS that undertakes the narrowband domain call control function, the active/standby dual-host mode is used. The user data of the controlled user is stored in HLR, and the routing data is stored in RS. After the host and backup machi

Softswitch devices are still commonly used. So I studied the security issues of softswitch devices and shared them here, hoping to be useful to you. For a new dedicated network, you can plan the bandwidth and use the call Count Control Function of SS to implement the network call congestion control function. First, we plan the total data bandwidth available for the softswitch device service between two loca

File System of embedded devices The system needs a method for storing and retrieving information in a structured format, which requires the participation of the file system. Ramdisk (see references) is a mechanism for creating and mounting a file system by using the computer's ram as a device. It is usually used for diskless systems (including micro-embedded devices, of course, it only contains flash chips
