Application layer attacks do not use traffic or sessions to flood the network, but slowly deplete resources on the application layer for specific applications/services. Application layer attacks are very effective at low traffic rates. From a protocol point of view, the traffic involved in the attacks may be legitimate. This makes application layer attacks more difficult to detect than other types of DDoS attacks. HTTP flood, DNS dictionary, Slowloris, and so on are examples of application layer attacks.3. Physical period: Uniform circular motion is a kind of periodic motion. The so-called periodicity refers to the fact that after a certain period of time, the moving object repeats back to its original position, and the instantaneous speed repeats back to its original size and direction. The time it takes for an object to move in a uniform circle is called a period. The period is expressed by the symbol T, and the period is also a physical quantity describing the speed of uniform circular motion. The long period indicates the slow motion of the object, while the short period indicates the fast motion of the object.Compiling: Netease's Outside Compiling Robot
