Analysis of TCP/IP protocol families in iOS Socket, iostcpIntroduction
This article mainly reviews TCP/UDP, HTTP, and Socket in the TCP/IP protocol family.(-- This article is very dry and has been brewing for a long time! Can you watch it patiently? O_o)

Port. If the port is busy while the TCP status is in another status, an error message is still returned when the port is reused,
Specify "The address is in use ". If you want to restart the service immediately after the service program is stopped, and the new socket is still
When the same port is used, the so_reuseaddr option is very useful. You mu

Preface
Although the network programming socket many people will operate, but many still are not familiar with the socket programming, the low-level TCP/IP protocol interaction process, this article will a simple client program and the service side program interaction process, uses tcpdump grasping the package, the example explains
TCP/IP Study Notes (1)
I. TCP/IP structure:TCP/IP is a layer-4 protocol with the following structure:1. Application Layer: various applications and protocols, such as HTTP and FTP.2. Transport Layer: TCP and UDPTCP provid
What is TCP/IP?
TCP/IP is a communication protocol for computers connected to the Internet.
TCP/IP refers to the Transmission Control Protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol ).
Cited:http://coach.iteye.com/blog/2024511What are TCP and UDP, and what are the differences between them?TCP is all called Transmission Control protocol. This protocol can provide connection-oriented, reliable, point-to-point communication.The UDP full name is the User Datagram Protocol, which can provide non-connected unreliable point-to-multipoint communication.With T

Through the preliminary understanding, I know that the IP protocol corresponds to the network layer, the TCP protocol corresponds to the transport layer, and the HTTP protocol correspond

Abstract:This paper introduces a simplified implementation scheme of embedded TCP/IP protocol in low-speed processors, and is successfully applied to a distributed monitoring system.
Keywords:Today, TCP/
IPThe IP layer (the network layer) receives packets sent by the lower layer (network interface layers, such as Ethernet device drivers) and sends the packet to a higher level---TCP or UDP layer (transport layer), whereas the IP layer transmits packets received from the TCP or UDP layer to the lower level.

TCP and UDP Use the same network layer (IP), TCP provides a connection-oriented, reliable byte throttling service.Connection-oriented means that only two parties communicate with each other. Broadcast and multicast cannot be used for TCP.The reliability of TCP
