Systems (distribution System): logical components belonging to 802.11 that are responsible for forwarding frames to the destination. A distributed system is a backbone network that forwards frames between access points, so it is often referred to as a backbone (backbone network).The RTS frame itself has two purposes: to reserve the right to use the wireless link and to remain silent on other workstations that require this frame to be received. Once the RTS frame is received, the receiving end i

Explore the efficiency of half-duplex Gigabit Ethernet switches. Recently, GE Ethernet switches have been favored by many friends. Today, let's take a closer look at the charm of GE Ethernet switches! To solve the efficiency problem of half-duplex Gigabit Ethernet switches, IEEE introduces the frame burst technology.
For example, if a DTE sends a 64-byte frame, MAC will add a 512-64 = 448byte carrier extension sequence to it. If the frame length sent

many triangles, the number of triangles determines the precision of the model, because we have more than enough time to use triangles in our needs, not to mention 2D special effects.
The general idea is as follows: our special effect is a triangle belt, and this special effect is followed by the blade or people (we will follow the special effect following the goal below, it is the people here or the cutting edge, called the special effect carrier). I

Brew Distribution System (BDS) is a commercial solution designed for developers and operators,It mainly solves problems such as how to distribute application software to users and pay for the application software to developers. It plays an extremely important role in brew end-to-end solutions and is a centralized embodiment of business models.
BDS provides a comprehensive directory management function that allows operators to maintain their product directories, allowing operators to customize mo
