udp flood

UDP is also one of the basic Internet protocols. Like TCP, It is a protocol in the transport layer. Then we will introduce the specific situation of this agreement in detail from the following article. However, UDP is a non-connection-oriented protocol. TCP is a surface connection protocol ). The establishment of a UDP connection does not require the server to li

As an important class of TCP protocol, the concept, function, and function of UDP protocol. Next we will introduce it in detail. I hope you will understand this agreement. UDP protocol User Data Protocol (UDP) is also a communication Protocol on the OSI transport layer. However, UDP is a non-connection-oriented protoco

Differences Between TCP byte stream and UDP datagram, tcpudp "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 For example, TCP. You have a reservoir in your house. You can pour water

Socket is a set of interfaces built on the TCP/IP protocol is not a protocolApplication layer: HTTP FTP SMTP WebTransport layer: Provides logical, not physical, communication between two applications (TCP UDP)TCP reliable connection-oriented servicesUDP unreliable, non-connected serviceAs long as the underlying implementation of the TCP IP protocol can be used to communicate with the socket1. TCP and UDP1.1 TCP ConnectionsThe TCP protocol can provide

Network communication In addition to the way the TCP, there is a way to implement the UDP way. UDP (user Datagram Protocol), the Chinese meaning is the Customer datagram protocol, similar to send short message, is a cheap way of communication, use this way without establishing a dedicated virtual connection, because no need to establish a dedicated connection, so the pressure on the server is much smaller t

one. UDP ProtocolUDP (user Datagram Protocol) protocol is a "Subscriber datagram Protocol", which is a non-connected protocol, and no connection is primarily compared to the TCP protocol. We know that when transmitting data using the TCP protocol, it is first necessary to establish a connection (the so-called handshake) to transmit the data. When the computer uses the UDP protocol for data transmission, the

From: China Linux Forum Iptables and SOCKS5From the "iptables and natcheck" article, we can see that, as long as both ends use iptables for Nat, even if both sides pass the natcheck compatibility test, iptables can never cross each other.What should we do? One way is to add a Transit server on the public network. UDP Communication Between Intranet machines on both sides is conducted by the Transit server (as long as the tr

Finally, I found a satisfactory explanation of UDP punching principle, attached the text, and sorted out the source code. 3.3. UDP hole punching UDP Punching Technology The third technique, and the one of primary interest in this document, is widely known as "UDP hole punching. "UD
