The main reason why DDOS attacks are difficult to defend is that there are too many vulnerabilities and attack methods that can be exploited. In the OSI seven-layer network model used in the network data transmission process, basically each layer has protocols that can be exploited by DDOS attacks. According to the different network levels of the protocols used for DDOS attacks, this paper summarizes the currently known DDOS attack types and their defense measures as shown in Table 1-3. For more detailed information on current DDOS attack and defense, please refer to Huawei DDOS attack and defense summary post."This' knowledge 'is out of ammunition, Before, we used ordinary bullets to hit these big wasps. So the killing efficiency is not high, After hitting them with '74 jets', We found that they were very afraid of fire. So he took out all the tracer armour-piercing bombs that were pressed at the bottom of the box. These bullets have three more functions than ordinary bullets: luminous, armor piercing and burning. This kind of bullet is mainly to use the tracer function to provide target indication for friendly fire. It works best at night, Then there is the use of this kind of ammunition to collect fire and shoot at the ammunition and fuel accumulation areas of the Vietnamese army. Because they can wear armour, So it can break through some relatively hard shells, Like car doors, Oil drum skins and so on, Then blow off inflammable and explosive substances such as ammunition and gasoline, In order to destroy the enemy's military materials, Because the above assumption was that the Vietnamese army might fight with our army in positional warfare, It is the kind of positional warfare in which the two sides fight each other. That's why so many of these munitions are being distributed, But this is not the case, The Vietnamese army did not have the patience to build positions to fight our army. But directly launched the attack, The envisioned positional warfare turned into defensive warfare, That's it, In the battle before position 149, there was basically no place where the three functions I mentioned above could be used. In this way, those traced armour-piercing firebombs are basically useless. In order not to let them get in the way, they were piled up at the bottom of all the ammunition. At that time, they were taken out at the right time. We used the battle gap to replace all the ordinary bullets with traced armour-piercing firebombs to hit the second batch of big wasps. The effect was not good.南宋中叶，局势纷乱，郭、杨两家惨遭灭门，其后人各散东西。郭家后人郭靖（张智霖饰）为人正直坚毅，自小得江南七怪传授武艺，更先后习得洪七公（刘丹饰）之“降龙十八掌”及周伯通（黎耀祥饰）之“九阴真经”。靖结识了灵敏活泼的黄蓉（朱茵饰），二人展开了一段生死相许的爱情另方面，杨家后人杨康（罗嘉良饰）为金人完颜洪烈收养，贵为太子。康及后与靖相认，更查出烈为他俩的杀父仇人，惜康利欲薰心，竟认贼作父。为取得“九阴真经”及“武穆遗书”两本绝学，康与西毒欧阳锋联手对付靖，更杀死江南七怪及嫁祸东邪，欲借刀杀人。武林大会“华山论剑”举行在即，“九阴真经”成为各派争夺的目标，靖更是众矢之的，一场武林浩劫即将爆发！Heavy Ming Jade Belt Hook, All [Skill Damage] +5%.郑海鹰和白桦的婚姻，在七年前解体。心高气傲的郑海鹰，像躲避瘟疫一样，躲避有关白桦的任何话题。偏偏事与愿违，牵涉白桦的种种切切，还是围绕在她身边集中爆发了。退休工人郑万年和老伴高凤兰为三个女儿各不相同的婚姻生活牵肠挂肚。大女儿郑海鹰，是个名律师，丈夫白桦，是一家银行的副行长，仕途看涨。这一对成功男女，常常是心有灵犀一点通，一度成为老郑家引以自豪的模范夫妻。功成名就的白桦，对家庭生活有了新的追求，他希望自己的妻子是个温柔体贴的贤内助，甚至最好是个全职太太。但郑海鹰事业性过重，没有任何通融的余地。七年前，白桦因病住院，当需要亲属在手术单上签字的时候，郑海鹰因忙于出庭而没能在医院陪护。年轻美丽的方卉以白桦妻子的名义，顶着压力在手术单上签了字，并精心照顾白桦。“苍蝇叮住有缝的蛋”，日久生情，郑海鹰无奈和白桦散伙。方卉甚至为了顺从白桦，心甘情愿地当上了全职太太。郑海鹰的离异和七年来一直没有重组家庭，成为老郑家永远的痛。二女儿郑海燕，在老郑家取代了大姐一家模范夫妻的地位。郑海燕和丈夫陈克加表面上“夫唱粗制滥造的劣质游戏上不了台面，更是难以持久。榊真喜男（长濑智也饰）是关东黑社会锐牙会所老大的儿子，肩负着继承会所的重大使命，可是由于他“考虑事物的能力只有前90秒”，稍谈不拢就以暴力解决，好几笔生意都被他搅黄，给组织造成重大损失。
