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).Over 30 million and over 50 million在八十年代，香港经营当铺的江苏和在广州当女工的董知书是典型的中港婚姻。二人婚后，仍然相隔两地各自生活，知书先后为江苏诞下大女儿江海潮及小女儿江海澜，知书对没有生下儿子而内疚，但一双女儿生得聪明伶俐，标致可人，总能令大男人的江苏展露笑容，知书简直当一双女儿是心中瑰宝。经多年的申请，知书和两名女儿终获得来港的单程证。就在知书欢天喜地的带着分别五岁及三岁的女儿到深圳火车站，准备来港定居之时，却遇上贼人抢手袋，知书极度无助之际，幸得当时在深圳的香港过气古惑仔崔志文见义勇为，挺身帮忙，二人追贼而去，留下海潮照顾海澜。偏偏这时竟有人乘乱将海澜拐走，姐姐海潮本来是可以大声叫「救命」的，但在电光火石间，海潮竟然没有作声，就这样眼巴巴让海澜被带走了！知书只有带海潮来港定居，每年上大陆寻小女儿，但海澜像是人间蒸发般无法寻回，令知书的心上有一片挥之不去的阴霾，经常发恶梦。海潮长大后，亦有内咎感，总觉得是自己的责任令妹妹失踪！匆匆二十载过去，当日被拐走的海澜，辗转被一对国内的医生夫妇所收养，且养育成人！也因此，便形成一个奇怪的现象：大家拼命想把女儿嫁入两家，却少有人愿意娶两家的女儿。草庙村被屠，少年张小凡双亲离世，被青云门大竹峰收留。机缘巧合之下，他习得佛门天音功法，又意外获得魔教法器烧火棍，踏上强者之路的同时，也让他陷入了巨大的危机。至魔法器的现世，与陆雪琪、碧瑶、田灵儿三个女生间命运的交错，都让他原本单纯的人生轨迹充满变数。一个勇者驳斥命运的传奇之旅就此展开......恶搞神剧《西游之妖怪别跑！》借古刺今，借助名著《西游记》经典人物，结合现实社会事迹为每集故事主线蓝本，叙述社会人情冷暖的道德问题。本剧将用幽默搞笑的叙述手法，反应现实社会中权谋与利益，或强拆拐卖、或坐地起价，或孤老无依，或言而无信等道德观，在每集剧中都以各种惩罚结尾，具有育人处事的宏观概念，具有一定教育意义弘扬中华民族正能量。
