The outer surface is plated with copper, and the raw material of the core wire is mainly aluminum. The outer surface is scraped and the aluminum core is silvery white. The quotation per unit of aluminum is about 1/4 of that of copper, and the same volume of aluminum is only 1/3 of that of copper, so the quotation per unit of copper clad aluminum is much cheaper than that of oxygen-free copper. Copper-clad aluminum has poor oxidation resistance, faster oxidation speed in humid environment, and poor tortuosity resistance of aluminum raw materials. It is not suitable for laying in the wall, and is only suitable for customers who do not have high demand for network stability or may temporarily establish a network.
Reset authentication takes advantage of the reliability of TCP protocol, and DDOS protection system responds to syn first. When the protective device receives syn, it responds to syn_ack and sets the Acknowledge number to a specific value (recorded as a cookie). When the real client receives this message and finds that the acknowledgement number is incorrect, it will send a reset message with a sequence number of cookie + 1. The source of the forgery will not have any response. In this way, we can add the real client IP to the white list. ?

该剧是从全国打拐行动的众多卷宗中，精选出8个有代表性的案例连贯相衔而成的。剧本广泛征求意见，几易其稿，还原生活又高于生活。从筹拍到实拍用了两年的时间。剧组行程几万公里，追踪采访拐卖案中受害者及家人。 这是一部特别震撼人的纪实电视连续剧，其中许多父母卖房卖血走天涯也要找寻骨肉的场景，令整个拍摄场地泣不成声。用导演范建会的话说：“把打拐放在后面，把家庭的悲剧放在前面，把客观事件放在后面，把事件中的人推在前面，是这部纪实电视剧最大的艺术特色。”
