Compared with SYN cache method, SYN? Cookies technology does not need to allocate space at all when receiving a SYN. Because the most basic data that make up the connection state are encoded and compressed into the sequence number bits of SYN-ACK. For a legitimate connection, the server will receive an ACK message segment with a serial number (actually the serial number has been added by 1), then the basic TCB data will be regenerated, and a complete TCB will confirm that the data will be safely instantiated through decompression. This decompression can be successful even under severe attacks, because there is no storage load at all on the host side, only the load that calculates the encoded data into the ACK sequence number. The disadvantage is that not all TCB data can be added to the 32-bit sequence number segment, so some TCP options required for high performance cannot be encoded. Another problem is that such SYN-ACK message segments will not be forwarded (because forwarding requires complete state data).Builder mode refers to separating the internal representation of a product from the construction process of the product, thus enabling a construction process to generate product objects with specific different internal representations. It emphasizes the construction process of the product. The main points of its implementation include:因女友自杀而患上抑郁症的警察阿斌（祖峰 饰）和搭档磊哥（陈明昊 饰）在调查一起碎尸案中，与被害者的姐姐李雪（黄璐 饰）相识。李雪自称梦见弟弟被人杀害。在调查过程中，阿斌发现李雪痛失女儿并患上抑郁症的悲惨经历，两人彼此怜悯，相互理解。 这时，在城市漂泊的少女婷婷（张倩如 饰）也渐渐走入阿斌（祖峰 饰）的生活，和他产生说不清的牵绊。 孤独的少女、备受抑郁症折磨的患者，他们都该如何面对自己的内心，又该如何在这个世界寻找光明……女人的天性使Ellen不自觉地侵入了Mike的个人空间，令不羁的Mike产生抵抗情绪，可是也终被Ellen的无条件付出感动，两人携手一起生活。然而在激情和温馨过后，因为Mike的公司出现经济困境，两人开始不断的争吵，暴露出各自的世界观有巨大差异的事实。在极度失意下，Ellen 提出分手，但像香港城的沦陷成全了白流苏和范柳原一样，一年后旧金山发生的大地震，为他们的重新牵手提供了契机。
