1.端到端原则（end-to-end principle）
当咱们联想个大的系统（如操作系统或条约族）时宜宾设备保温工程 ，随之而来的个问题持续是在什么位置闭幕某个。影响TCP/IP条约族联想的个伏击原则是端到端原则（end-to-end principle）：只须在通讯系统端点的诈欺常识的匡助下，才能和正确地闭幕问题中提到的。这种不雅点标明底层不应计谋划，这是因为对诈欺法子需求作念出测是弗成能的。

Fate-sharing is an engineering design philosophy where related parts of a system are yoked together, so that they either fail together or not at all. Fate-sharing is an example of the end-to-end principle. The term "fate-sharing" was defined by David D. Clark in his 1988 paper "The Design Philosophy of the DARPA Internet Protocols" as follows: The fate-sharing model suggests that it is acceptable to lose the state information associated with an entity if, at the same time, the entity itself is lost. Specifically, information about transport level synchronization is stored in the host which is attached to the net and using its communication service. A good example of fate-sharing is the transmission of routing messages in routing protocols such as BGP, where the failure of a link or link interface automatically has the effect of terminating routing announcements through that interface, ultimately resulting in the tearing down of the state for that route at each end of the link. Similar considerations apply to TCP.
它说庆幸分享是端到端的种法式，我的贯通是：庆幸分享等于把总共景仰个看成的通讯关联（如臆造连结）所须的气象皆放在通讯端点，通过端点间的气象信推辞换来保管连结，铁皮保温施工而不是通过各自检测本色的总共这个词通讯连结中的中间实体（路由器，交换机，领路等）是否有。这么的克己是：(1) 通过气象交换能否到达就能且正确地判断连结是否有。(2) 在网罗基础格式中有些单位失地情况下，不会影响网罗诞生的通讯才调（只须有些通讯旅途仍然可用）。 念念念念庆幸分享的替代法：淌若中间实体须景仰关系通讯的气象，那么您将靠近复制该气象的贵重，即该贯结过的总共中间实体皆得保执份通讯气象的拷贝。 参考而已：https://www.niem.es/2008/04/term-fate-sharing.html
