SIP (Session Initiation Protocol, conversational initial protocol) was developed to help provide advanced telephony services across the Internet. Internet telephony (IP telephony) is evolving into a formal business telephony model, and sip is an important part of the NGN (Next Generation Network) family of protocols needed to ensure this evolution.

The category classification file in OC is equivalent to some classes in C #, and the Protocol protocol file in OC (essentially a header file) is equivalent to an interface in C #. Here is a brief explanation of the two files in OC today.Since the video in the Xcode version is low, resulting in the classification files and protocol files are not found, and finally

General Overview: 1 Overview The Android Debug Bridge (ADB) is used: ADB is used in the following scenarios: Keep track of all Android devices and emulators instances connect

I. Analysis of the Three-way handshake protocol First, let's look at one of the most common things in our life: During our online shopping, we often chat with customer service like this: We asked Customer Service about something, Customer Service answered, and then we broke the network... After a while, we will log on again and receive a response from the customer service. This interaction process completes a response three times. This process

1 Introduction of the Protocol 1.1 Protocol Overview The intermediate system to the intermediate system Is-is (intermediate system to Intermediatesystem) belongs to the Internal Gateway Protocol IGP (Interior Gateway Protocol) for internal autonomous systems. Is-is is also a link state

PPP is one of the most basic protocols in the network. PPP is the main content of this article. First, let's take a look at the basic concepts of the PPP protocol. The Point-to-Point Protocol is a data link layer Protocol designed to transmit data packets between equal units. This link provides full duplex operations and transmits data packets in sequence. PPP pr

Chapter 3 _ IP Internet Protocol IP header IP protocol is the most core protocol in the TCP/IP protocol family. All TCP, UDP, ICMP, and IGMP data are transmitted in IP datagram format. The IP address provides unreliable and connectionless services. Unreliable: IP datagram cannot be successfully delivered to the destina

What is the working principle of HTTP? How to optimize the HTTP protocol ?, Protocol Working Principle Optimization made by http1.0 Bandwidth: latency has been solved at this stage: 1. browser blocking: the browser can only connect to the same domain name with four connections at the same time. latency: 2. DNS query: The Browser needs to know the IP address of the target server to establish a connection del

Send the monkeys to the reinforcements.An RFC document on ICMP here!What the hell?In my opinion, the ICMP protocol is mainly to pass/query some basic information to each other, most of which is to pass some error message.For example, a sends the UDP message to B's 10000 port, but B's 10000 port does not open, it will return an ICMP packet to a, tell the A10000 port is not open.Basic query information, such as the most commonly used ping command, is to

OverviewBoth TCP and UDP use the same network-layer IP, but unlike UDP, TCP is a connection-oriented, reliable byte-stream protocol. Therefore, both parties must establish a TCP connection before transmitting the data. TCP realizes the transmission of reliability through the mechanism of verification, serial number, acknowledgment response, retransmission mechanism, Connection management and window control.TCP provides reliability in the following way

To put it simply, the svn + SSH (SVN over SSH) protocol works by establishing an SSH connection between the svn client and the server, and then pushing commands and transmitting data through the SSH connection, to achieve more secure SVN communication through SSH. Using SVN + SSH to access repository is the biggest difference from common HTTP or HTTPS methods, or the only difference is to log on to the remote host through SSH Security Authentication T

Msnp9 Protocol Analysis Report 1. Connection The MSN Messenger protocol is built on TCP/IP. In addition to direct "point-to-point" communication between file transmission and voice chat, all other scenarios are performed through the server. Logically, there are three types of servers with their respective roles: Dispatch server (DS)-the server on which the client first connects. Allocates appropriate notif

Logical Organizational Structure The logical organization of a USB device consists of four layers: device, configuration, interface, and endpoint. A device usually has one or more configurations. The configuration usually has one or more interfaces with zero or multiple endpoints. Each USB device can contain one or more configur

Baidu Encyclopedia Description:Hypertext Transfer Protocol (Http,hypertext Transfer Protocol) is one of the most widely used network protocols on the Internet. All WWW documents must comply with this standard. HTTP was originally designed to provide a way to publish and receive HTML pages. 1960 American Ted Nelson conceived a way to process text messages through a computer called hypertext (hypertext), whic

The following configuration steps provide detailed answers.
