DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.

Est (2, true, 500); This method does not match from the first node order500 in the chain, returns the success string, and then this.success & & this.successor.passRequest.apply (this.success, arguments); Execute this code; As we said above, the attribute this.Successor refers to two methods, order200 and orderNormal, so the method order200 is called, so the value is returned, and so on. Then if we want to recharge 300 yuan's red envelopes in the future, we can write the function Order300, then list the chain chain and package it, and specify the order in the responsibility chain.
