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).Blast wounds at position 6% (+14) 50%聪明可爱的小谢耳朵和他的家人、朋友们回归。这季中，小谢尔顿从高中毕业即将进入大学生活！意外出名的农民歌手万喜，衣锦还乡后被乡亲们选为村长。万喜本想在村里大干一场帮助大伙脱贫致富，没想到乡亲们根本不想改变现状，只想利用他的名气多要点救济款。万喜不愿当个“要饭”村官，他顶住压力大力发展特色农牧业，却遭遇种种困难与挫折。万喜疲于应付，幸好他的初恋杏花帮忙解决了不少难题，这也引起了万喜媳妇梅花的误会。收获季节，农产品滞销，乡亲们责怪万喜无能想换个村长。万喜说服乡亲们让他试用几个月，发誓让大伙挣得比扶贫款多几倍。为了实现对乡亲们的承诺，万喜聘请了女大学生田欣帮助大伙利用互联网卖农产品。在众人的努力下，农产品销售一空。万喜实现了承诺，成为乡亲们认可的村官Zhao Mucheng finished, silent.柏崎结衣（泽尻英龙华）原本过着相夫教子的幸福生活，直到某天，3岁的儿子在回家时被绑架，从此音讯全无。崩溃的结衣选择了离婚，在友人的劝说下好不容易才回到了正常生活轨迹。9年后，母子偶然重逢，而收养儿子的是一名强烈渴望成为人母的女性门仓麻子（小池栄子），她们之间又会产生什么样的新的纠葛？
