LINUX tcp/ip性能调优 On 2011年03月15日, in linux, tips, by netoearth 在TCP/IP协议中,TCP协议提供可靠的连接服务,采用三次握手建立一个连接. 第一次握手:建立连接时,客户端发送syn包(syn=x)到服务器,并进入SYN_SEND状态,等待服务器确认: 第二次握手:服务器收到syn包,必须确认客户的SYN(ack=x+1),同时自己也发送一个SYN包(syn=y),即SYN+ACK包,此时服务器进入SYN_RECV状态: 第三次握手:
# Kernel sysctl configuration file for Linux # # Version 1.12 - 2015-09-30 # Michiel Klaver - IT Professional # http://klaver.it/linux/ for the latest version - http://klaver.it/bsd/ for a BSD variant # # This file should be saved as /etc/sysctl.conf
以下是从stackoverflow上抄下来的,很有帮助 How can you have a TCP connection back to the same port? A TCP connection is uniquely identified by this tuple (local address, local port #, foreign address, foreign port #). There is no requirement that local address and

TCP/IP网络知识点总结 一.总述 1.定义:计算机网络是一些互相连接的.自治的计算机的集合.因特网是网络的网络. 2.分类: 根据作用范围分类: 广域网 WAN (Wide Area Network) 局域网 LAN (Local Area Network) 城域网 MAN (Metropolitan Area Network) 个人区域网 PAN (Personal Area Network) 根据使用者分类: 公用网 (public network) 专用网 (private netwo
