The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.

Changes in one responsibility may affect other responsibilities. In addition, coupling multiple responsibilities together will also affect reusability.

该剧是英剧《摩斯探长》的续篇，于2006-2015年在ITV播出，共九季33集，每集约90分钟，其中从2013年的第七季开始每集在ITV1首播时被拆分为上下两部分连续两周播出，然而在重播时以及在美国PBS电视台播出时依旧作为整集播出。该剧将背景设置在学术气息浓郁的牛津，剧中很多含有隐喻的诙谐对白在外国文学爱好者看来会别有趣味，同时延续摩斯系列侧重通过案件展示各色人生和命运悲剧的特色，凶手被揭露后通常会有一幕对手戏将矛盾推至高潮，尘埃落定后缓和而带有希望的片尾曲又形成鲜明映衬，让人感叹命运无常及人的渺小，同时又看到光明的希望。该剧多位编剧也曾参与ITV版大侦探波洛和马普尔小姐系列剧的改编。
BOT is the abbreviation of Build-Operate-Transfer, which is usually literally translated as "Build-Operate-Transfer". BOT is essentially a way to invest, build and operate infrastructure. On the premise of reaching an agreement between the government and private institutions, the government issues a concession to private institutions to allow them to raise funds to build a certain infrastructure and manage and operate the facility and its corresponding products and services within a certain period of time. The Government may limit the quantity and price of public goods or services provided by the Agency, but ensure that private capital has the opportunity to make profits. The risks in the whole process are shared by the Government and private institutions. When the concession period ends, the private organization will transfer the facility to the government department as agreed, and the facility will be operated and managed by the government designated department. Therefore, the word BOT is paraphrased as "infrastructure concession.
