The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.董小翠被在张家当雇工的商平勾引，怀孕后很慌张。这怀王之称就不一样了，是殿下对县尉的缅怀和憧憬，一腔孝心感动天下。中国警方在得到线报，获得以九子龙为首的国际制毒贩毒集团在大陆开辟的黄金通道—云南经广州，深圳至香港，进行全方位清理。贩毒集团的首领九子龙也被抓获，但经审查，被抓的人并不是九子龙！九子龙已经逃脱了法网，在此情况下，公安部缉毒局召回内线侦察员“火狐”命令他继续留在香港，查清九子龙的下落。九子龙在遭受打击之后，并没有潜藏起来，而是开辟了新的贩毒通道，把位于东海沿海的龙海市作为跳板，市公安局缉毒大队长王小波是闻名的缉毒英雄。他在获取毒团伙将在珍珠岛渡假村进行毒品交易的情报后，率领缉毒警包围了渡假村。但现场情况却出乎他的意料，毒枭麻三和几个日本买主全部昏倒在餐桌旁。王小波擒获了贩毒人员并缴获冰毒三千克，五百万美金毒资不翼而飞………为九子龙顶罪而入狱的曹东方因刑出狱而得到九子龙的重用，九子龙的干女儿阿丽和男友号称亚洲第一制毒手阿西在接曹东方出狱时遇上黑道追杀。曹东方对九子龙奴颜卑膝。就是为了要取代九子龙的霸主地位。军汉果然不是善茬，很是挣扎了一番。他使她的生活成为噩梦。 她和她的朋友们一起制定了复仇计划.富贵不还乡，有如锦衣夜行，再大的成功，又有谁知道呢？尹旭轻轻道来。
