DDoS is a distributed Dos attack (distributed denial of service attack). Through multiple hosts to a single server attack, that is, multiple hosts constantly to the server to initiate service requests, so that the server consumes a lot of CPU, memory, network bandwidth and other resources overwhelmed, can not provide normal service or even paralysis.DDoS protection is mainly from two aspects, that is, host

register the information of these stacks for temporary preservation in the TCB (e.g.).The steps for creating a stack of the X (x=0,1,2) privilege level are as follows:1. Apply for memory, allocate space for stack;2. Create a stack segment descriptor (DPL=X) in the LDT;3. Register the Stack's information in the TCB, including the stack size, base address, selector (rpl=x), and initial value of espx (=0);I t
