核心提示:-->With the development of the IP network to the multi-service network, especially the development of VoIP in recent years, it is inevitable to transmit signaling messages in the IP network. But in the IP network cannot provide high-quality transmission services like mtp3 and ATM, so the ITU-T proposed an improved version of sscop-sscopmce in Multi-link and non-connection environment ), it is used to transmit signaling messages in an IP-based network. However, compared with sscop, ssc

PPP has three main components:
Encrypts data packets on a serial line;
The Connection Control Protocol (LCP) used to establish, configure, and detect data link connections ).

Thank you!After a cursory look at IP relays and IP addresses, we turn to the specifics and design philosophy of IP protocols.comparison of IPv4 and IPv6 headWe have already introduced in the IP relay, an IP packet is divided into the header (header) and the data (payload/data) two parts. The head is the additional information necessary to implement IP communication, and the data is the information to be

The SSL (Secure Sockets Layer) protocol was first developed by the famous Netscape company. It is now widely used for identity authentication on the Internet and secure data communication between web servers and Client browsers.
The purpose of the SSL protocol is to provide secure and reliable communication protocol services for both parties, and establish a Tr
TCP (transmission Control Protocol, transmission Protocol) is a connection-oriented protocol,In other words, a reliable connection must be established with each other before sending or receiving data.A TCP connection has to be three "conversations" to build, and the process is very complex and simply describes the simple process of three conversations:

1. what is TCP/IP?
If you want to know a person, you can chat from the group where he belongs. Our HTTP protocol is a member of the TCP/IP protocol family. we understand the status of HTTP in the entire netwo
Preface: Because OBJECT-C does not support multiple inheritance, it is often replaced with protocol (protocol). The Protocol (protocol) can only define a common set of interfaces, but cannot provide a specific implementation method. That is, it only tells you what to do, but specifically how to do it, it does not care.
First, protocol1.

TCP is the host-to-host layer of the Transmission Control Protocol, providing a reliable connection service, using three-time handshake confirmation to establish a connection.

In terms of email, POP and IMAP are the most famous protocols. I don't need to talk about the POP protocol. Many users will be familiar with this protocol when setting some mailbox binding functions. Some friends may not understand the IMAP protocol. Here we will make a comparison between the two Protocols.
