1.IP协议 IP协议是TCP/IP协议簇中最核心的协议,所有TCP、UDP、ICMP及IGMP数据都以IP数据报格式传输,IP协议不可靠无连接。 2.IP数据报格式信息 IP首部一般长20字节,除非含有选项字段。 版本号:表示协议版本,现在协议版本号为4。 协议首部长度:表示首部站32bit字的数目,最长表示60个字节。 TOS字段:TOS包
以太网链路层协议包含:串行接口链路层协议(SLIP、PPP),环回(loopback)驱动程序。 以太网和IEEE802封装 目的地址和源地址长度为48bit(6字节),为硬件地址。 接着,802标准中,2字节的长度指后续数据的字... 《TCP/IP协议详解 卷1》--- 概述 分层1、链路层,又称网络接口层,处理与电缆的物理接口细节。 以太网协...
If the you receive an error, TCP/IP is not working correctly. To resolve this issue, try the following options: Ensure that the loopback interface is installed and configured correctly. For more information, seeInstalling and configuring the Loopback adapter in a virtual machine. or Reinstall T...

sysctl -w net.ipv4.tcp_tw_recycle = 1 , 打开快速回收TIME_WAIT,Enabling this option is not recommended since this causes problems when working with NAT (Network Address Translation) sysctl -w net.ipv4.tcp_tw_reuse =1, 快速回收并重用TIME_WAIT的链接,貌似和tw_recycle有冲突,不能重用就回收?

桥接容器,除了有一块本地回环接口(Loopback interface)外,还有一块私有接口(Private interface)通过容器虚拟接口(Container virtual interface)连接到桥接虚拟接口(Docker bridge virtual interface),之后通过逻辑主机接口(Logical host interface)连接到主机物理网络(Physical network interface)。 桥接网卡默认会分配到172.17....
总之,主要的思路是call-in的方式逐级进行函数调用,但是接收数据放入accept队列的代码我们还没有跟踪到,接下来我们需要换一个思路,网卡接收到数据需要通知上层协议来接收并处理数据,那么应该有TCP协议的接收数据的函数被底层网络驱动callback方式进行调用,针对这个思路我们需要回过头来看TCP/IP协议栈的初始化过程中是不是有...
