java udp

For a UDP server, if several UDP clients send data to it at the same time, and the UDP server uses a single-thread serial processing method to process received UDP packets, then, when the UPD server has not processed a packet, several other clients send data at the same time, and the data is accumulated together (or ov

The most complete difference between TCP and UDP TCP UDPBasic differences between TCP and UDP1. Connection-based and no-connection2.TCP requires more system resources, less UDP;3.UDP program structure is relatively simple4. Stream mode (TCP) and datagram Mode (UDP);5.TCP guaranteed data correctness,

is about 40 kbps, and is limited by bandwidth, it is best to use the data collection scheme, such as proactive alarms, data Round-Robin collection, and active call-back for alarms, which consume less bandwidth. In addition, considering the support for the real-time data collection solution of the front-end server, the wireless modem transmission solution can only be used as a supplement to the current transmission solution.With the continuous development of wireless communication technology, th

UDP is at the top layer of the IP protocol, which should be clear to everyone. Therefore, the complex protocol structure of the network constructs all aspects of the network. Today we will introduce the basic content of the UDP protocol. The UDP Protocol is short for the User data Protocol. It is mainly used to support network applications that need to transmit d

This article mainly introduces the C #-based UDP protocol synchronous implementation code, small series feel very good, and now share to everyone, but also for everyone to do a reference. Let's take a look at it with a little knitting. I. Summary Summarizes the synchronous communication of the UDP protocol based on C #. Second, the experimental platform Visual Studio 2010 Three, the principle of experiment

1.UDP Brief Introduction UDP is a transport layer protocol, and TCP protocol is in a hierarchy, but unlike the TCP protocol, UDP protocol does not provide timeout retransmission, error retransmission and other functions, that is, it is unreliable protocol. 2.UDP Protocol Header 2.1.

With the IP over SSL key idea, OpenVPN is an inevitable result, so not much to say, OpenVPN and OpenSSL is not at a level, although all very open. OpenVPN configuration is very complex, mainly in order to establish a more reasonable tunnel, although IPSec-implemented VPN does not differentiate between the client and the server, when the SA is established by the DH symmetric encryption key and algorithm, but based on the OpenVPN of OpenSSL is differentiated between the two, Because OpenVPN securi

to Host B. UDP (User data Protocol, Subscriber Datagram Protocol) is a protocol corresponding to TCP. It is a connectionless protocol that does not establish a connection with the other, but instead sends the packet to the past directly. UDP is suitable for applications where only a small amount of data is transmitted at a time and the reliability requirements are not high. For example, we often use t

TCP/IP, UDP, HTTP, socket inside and out The network is divided from bottom to top: corresponding Physical Layer Data Link Layer Network layer (IP protocol) Transport layer (TCP protocol) Session Layer Application layer and Presentation layer (HTTP protocol) The socket is the encapsulation and application of the TCP/IP protocol (at the programmer level). It can also be said that the TPC/IP protocol is the Transport Layer protocol, mainly to solve ho

official communication, regardless of the status of the other party directly sent. This is the Flying Pigeon biography ~ Although UDP is less reliable than the TCP protocol, communication efficiency is higher than TCP. In the case of extremely poor speed, the UDP protocol is preferred, TCP is very convenient to use when the network speed is good. Using TCP in Java
