Then in the program it means keeping references to multiple objects, The larger the program, There will be more and more objects, The relationship between them will become more and more complicated. Now if there is an intermediary (if it is our supervisor) to meet the needs of multiple demanders, Then the demander only needs to give all the requirements to our supervisor, who will assign tasks to us according to our workload in turn. In this way, our front-end development does not need to contact with multiple business parties, we only need to contact our supervisor (i.e. Intermediary), which weakens the coupling between objects.毛海峰随即嚎啕大哭。人对了就好。云影大笑着对郑氏道：嗳哟。刚才我都没敢拿出来，就怕她们抢了。经典功夫喜剧系列电影《龙威小子》故事未完，YouTube meijubar.net Red 打造续集影集《Cobra Kai》正式预告上线。34 年前在《龙威小子２》展开世纪对决的丹尼尔与强尼，时隔多年将再度交手，当时饰演两人的雷夫·马奇欧（Ralph Macchio）与威廉·萨巴卡（William Zabka）回归演出相同角色。Compared with other quite sophisticated network attacks, DDOS attacks are not only the use of attack techniques, but also a competition of resources, including network bandwidth resources and server resources.

Therefore, at present, the defense against DDOS attacks mainly lies in hardware protection, and software protection has little effect.
