For example, the firewall must analyze each packet to determine whether the packet is a discrete connection, the existence of an existing connection, or the end of an existing connection. Similarly, intrusion prevention systems must track status to implement signature-based packet detection and stateful protocol analysis. These devices and other stateful devices-including the equalizer-are frequently compromised by session floods or connection attacks. For example, a Sockstress attack can quickly flood the firewall's state table by opening a socket to populate the connection table.State mode refers to allowing an object to change its behavior when its internal state changes. The object seems to have modified its class. Divide this sentence into two parts by commas. The first part means to encapsulate the state into a separate class and delegate the request to the current state object. When the internal state of the object changes, different behavior changes will be brought about. The second part is from the customer's point of view, the object used has completely different behaviors in different states. The object seems to be instantiated from different classes, but in fact this is the effect of using delegates.大虾为了夺得“区域快递侠”，获得北京一所房子的奖励；为了能在北京有一个安身之地、能接母亲到北京居住，他排除万难，争夺“快递侠”。同时遭到竞争对手高彦直的多番阻碍。敦厚老实的中介卢伟文（吴镇宇 饰）与家庭主妇妻子淑贤（袁咏仪 饰）、失业愤青儿子（吴肇轩 饰）、沉迷网恋的女儿（蔡颂思 饰）及生活不能自理的父亲（张达明 饰）一家五口过着每月要还房贷的节衣缩食生活。鸡毛蒜皮的邻里纠纷、还不完的买房贷款、上有老下有小的尴尬处境，都成了这个家随时爆发争吵的源泉，而他们唯一舒缓焦虑的就是那一扇窗外的海景。可万万没想到的是，突然有一天，一块飞来广告牌完完全全阻挡到了整家人的视线，他们再也没有办法去舒缓压力。而这块广告牌的主人王小财（古天乐饰）却不以为然。解决无期、焦虑升级，卢伟文一家的疯狂计划就此展开……Public Iterator iterator () {
