在Hardware上面的一层是Host-to-Host Connectivity。由于我们网络的目的是能够让两端的主机能够连接,那我们在Hardware的上一层就可以想象成,我们有两个主机要连接起来做通讯,因此叫Host-to-Host Connectivity,表示两台主机之间可以做通讯。 而我们的主机上同时又会run很多应用,每一个应用可能会建好几个connection,变成pr...
本文首发自CS 144 Introduction to Computer Networking 心得 困惑 上一份工作时,我对除了 HTTP 之外的网络知识一无所知。每次遇到一些底层的问题我就像《星际穿越》里面的主角进入了黑洞,觉得头晕眼花。比如 当时经常要接入第三方的 Web API,刚开始调试不通,到底问题在哪里?是我们自己出错了还是对方出错了?遇到过的...
Introduction to Computer Networking学习笔记(十八):rate guarantees交换速度保证 简单的FIFO(先进先出)队列存在一个缺点,无法对包的优先级做出反应,即相当于先进入的包拥有更高的优先级,会首先被发送出去。但是实际应用中,数据包可能有优先级的概念,有可能优先级更高的包比普通包更晚进入队列。此时需要对FIFO进行改进...
WhenTCPConnectionAsends the segment toTCPConnectionB, it will calls theTCPSenderA'sfill_window()method to extract the data to the segments. It will maintain the absolute sequence number for the next byte to be sent. However,there is one thing we do not consider, how about the acknowledge n...
