Real-time audio and video domain UDP is the king In the Internet, audio and video real-time interaction using the Transport Layer Scheme has TCP (such as: RTMP) and UDP (such as: RTP) two kinds. The TCP protocol can provide a relatively reliable guarantee for data transmission between two endpoints, which is achieved through a handshake mechanism. When the data is passed to the receiver, the receiver checks

TCP and UDP are important in network transmission, as well as in Android development.First look at what TCP and UDP are.What is TCP?Tcp:transmission Control Protocol Protocol TCP is a connection-oriented, reliable, byte-stream-based transport layer (Transport layer) communication protocol, which is provided by the IETF RFC 793 description (specified). In the simplified computer network OSI model, it accompl

UDP Protocol Introduction UDP transmission is very similar to IP transmission. You can regard UDP as an interface that exposes the IP protocol to the transport layer. UDP also transmits data packets in the form of "Best Effort", so UDP is also unreliable ). So why do we need

I. Overview TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two different communication protocols at the transport layer in the network architecture TCP/IP model. TCP: Transmission Control Protocol, a connection-oriented protocol that provides a reliable full-duplex byte stream for user processes. The TCP set interface is a type of streamsocket interface. UDP: User Datagram Proto

The difference between TCP protocol and UDP Protocol (RPM)First we find out that the TCP protocol and the UCP protocol and the TCP/IP protocol, many people confused, has always been the TCP/IP protocol and the difference between the UDP protocol, I think it is not fundamentally clear network communication!The TCP/IP protocol is a protocol cluster. It includes a lot of protocols.

TCP: Transmission Control Protocol, a connection-oriented protocol that provides a reliable full-duplex byte stream for user processes, and a TCP socket interface is a type of byte-throttle socke

1. Overview Some common applications written using UDP include DNS (Domain Name System), NFS (Network File System), and SNMP (Simple Network Management Protocol) Provides typical function calls for UDP client/server programs: 2. recvfrom and sendto Functions Two functions are similar to the standard read and write Functions, but three additional parameters are required. # Include The first three parame

After the standard UDP client has opened a set of interfaces, it generally uses the sendto and recvfrom functions to send data. Recently, we can see that the ntpclient Code uses the direct method of the send function, so we have analyzed it, in the past, UDP sent data in two ways for you to choose from, by the way, UDP connect usage will be clearly explained.Meth

UDP belongs to the transport layer together with the TCP mentioned earlier. UDP differs from TCP in that it is a non-connection-oriented protocol, that is, when both parties communicate with each other, they do not need to establish a connection beforehand. So the UDP header saves a lot of fields, and the UDP header i

TCP byte stream and UDP datagram "TCP is a stream mode protocol and UDP is a datagram mode protocol". I believe you are familiar with this sentence ~ However, what is the difference between "stream mode" and "data packet mode" in programming? The following is my understanding for your reference only! 1. TCP stands for a metaphor for TCP. You have a reservoir in your house. You can pour water in it. There is

The first thing to look at is TCP/IP protocol, which involves four layers: link layer, network layer. Transport layer, application layer.The data frame of the Ethernet (Ethernet) in the link layerIP packets on the network layerTCP or UDP packets in the transport layerdata in TCP or UDP is in the application tierTheir relationship is the data frame {IP packet {TCP or UDP
