voice protocols

The most basic concepts in network programming are connection-oriented (connection-oriented) and non-connected (connectionless) protocols. In essence, the difference between the two is not difficult to understand, but for those who are just beginning to network programming, it is a very confusing problem. The problem is somewhat related to the context: Obviously, if two computers are to communicate, they must be "connected" in some form, what does "no

What is gateway? gateway is also called the inter-network connector and Protocol converter. The gateway is the most complex network interconnection device on the transport layer to achieve network interconnection. It is only used for different network interconnection between two high-level protocols. The structure of the gateway is similar to that of the router. The difference is the Interconnection layer. Gateways can be used for both Wan and LAN int

The relationship between the network level protocol and the structure system between the LAN and the Internet communication is completed with the support of different network levels and network level protocols. So what are their definitions and functions? How can we locate the protocol, structure, system, and hierarchy? Next, let's take a few more details. 1. Several Basic concepts in a hierarchical architecture (1) Protocol is a communication Protoco

Introduction to TCP/IP and other network protocols 1. TCP/IP is a communication protocol for the Internet. Computer Communication Protocols are descriptions of the rules that computers must comply with in order to communicate with each other. TCP/IP refers to the Transmission Control Protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol ). TCP/IP defines how electronic devices (such as

We all know that the destination address can be effectively selected for data distribution when the routing selection protocol is used. So how can we allocate resources when multiple protocols coexist? Now let's talk about this issue. I. Redistribution 1. Redistribution means that when an organization runs multiple routing protocols, it must notify the network learned by one routing protocol to the other by

Common protocols such as TCP,UDO,HTTP,SIP are commonly found. The protocol has process specifications and coding specificati

that the Redis client communicates with Redis, and the communication protocol specifies the format of the command and return values. Understanding the Redis communication protocol not only allows you to understand the format of the AoF file and the contents of the master database to be sent from the database during master-slave replication, but also to develop your own Redis client (although there are corresponding Redis clients in almost all common languages). There is really not a lot of oppo

handshake protocol. SSL is developed by Netscape to protect Web communication. The current version is 3.0. The latest version of TLS 1.0 is a new protocol developed by IETF (engineering task group). It is based on the SSL 3.0 protocol specification and is a later version of SSL 3.0. The difference between the two is very small. it can be understood as SSL 3.1, which is written into RFC.SSL (Secure Socket Layer) is developed by Netscape to ensure the security of data transmission over the Intern

to send IP groups that do not know where to send them. In this way, the router correctly forwards IP groups that know how to transfer them, and the IP groups that do not know are sent to the "Default Gateway" router. In this way, the IP Group will eventually be sent to the destination, IP groups that cannot be sent to the destination are discarded by the network. Currently, all TCP/IP networks are interconnected through routers. The Internet is an international network that connects thousands o

Cp http udp: All are communication protocols, that is, the rules observed during communication. Only when both parties "speak" according to this rule can the other party understand or serve it. Relationship Between tcp http and UDP: TCP/IP is a protocol group, which can be divided into four layers: network interface layer, network layer, transmission layer and application layer.The IP protocol, ICMP protocol, ARP protocol, RARP protocol, and BOO

The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensa
