The other two schemes are based on SYN cache and SYN? Cookies (see 6.4), simplifies the state initialized when the TCB is generated by receiving the SYN, and delays the instantiation of the full state [4]. In hosts that use SYN caching, a HASH tablespace with a limited size is used to store a subset of data that will be allocated to the TCB. If the ACK is received when the handshake is completed, the data will be copied into a complete TCB, otherwise HASH values exceeding the lifetime will be recycled when needed. In Lemon's FreeBSD, the SYN cache is 160 bytes for a half-open connection, while a full TCB is 736 bytes and supports 15,359 SYN cache spaces.这个人太厉害了，这种情形下，居然还能利用各方形势……他说了一半，就停住，闭上眼睛，仿佛在整理思绪。Resource isolation can be regarded as a protective shield for user services. This protective system has extremely powerful data and traffic processing capabilities to filter abnormal traffic and requests for users. For example, for Syn Flood, the shield will respond to Syn Cookie or Syn Reset authentication, filter forged source data packets or attacks of power generation through authentication of data sources, and protect the server from malicious connection erosion. The resource isolation system mainly protects the third and fourth layers of ISO model. The schematic diagram of resource isolation is as follows:菊池风磨主演《写不出来！？》的衍生剧《大学生仙川俊也的无剧情人生》，故事讲述圭佑（生田斗真）和奈美（吉濑美智子）的儿子?吉丸空（润浩）的家庭教师?仙川俊也（菊池风磨）的日常生活。吉丸家和东西电视台的成员也将陆续登场！by:meijubar.net该剧描述的是，北方武术高手姜铁山（张铮饰）擅使“夺命长枪”，威震北方，其女姜文英（米雪饰）个性豪爽，亦有好身手。有人前来姜家托镖，因铁山有事，文英与母亲苗玉娘（郭锦华饰）代为护镖，不料途中被劫，玉娘受重伤，文英则被人掳走等一系列江湖恩怨的故事。
