verizon udp

The difference between packet-oriented (UDP) and byte stream (TCP) is that the packet transmission mode is the maximum number of packets sent to UDP at the application layer, and UDP sends one packet at a time. Therefore, the application must select the appropriate size of packets. If the message is too long, the IP layer needs to be split to reduce the efficienc

In some Java programming, we often involve the use of UDP protocol, so today we will elaborate on the use of UDP protocol in Java. First, you need to understand the basic concepts and significance of UDP. What is UDP? The full name of UDP protocol is user datagram, which is

When learning the tcp udp protocol. We always compare the two to learn from each other. This is because, in some respects, these two protocols always confuse us. In order to clearly define their respective definitions, we must distinguish them. So what are the essential differences between the two? Let's first look at their respective definitions. TCP: Transmission Control Protocol, that is, the Transmission Control Protocol.

OverviewUDP is a non-connected, unreliable datagram protocol, and any reliable transmission needs to be provided by the application, such as: time-out retransmission, serial number response mechanism, but it is efficient and convenient to use in some situations. It supports broadcast and multicast. The basic UDP socket programming reference to this article, this is only on that basis, to record some of the problems in the

create (and maintain) a connection when passing data. This connection adds overhead to the communication process, making it slower than UDP. Resource Consumption of TCP connections, including packet information, condition status, and serial number. TCP connection has security risks: by deliberately failing to complete the three-way handshake process required for establishing a connection, the resources of the connection party are exhausted. The pre

segmentation occurs at the network layer. However, for segments, this often happens on the UDP Transport Layer Protocol, which rarely happens on the transport layer using TCP channels. 1, MTU (maximum transmission unit, MTU), maximum transmission unit (1) Ethernet and 802.3 have a limit on the length of data frames. The maximum values are 1500 and 1492 bytes, respectively. This feature of the link layer is called MTU. Most networks of different types

In the previous articleArticleAt the end of the section, I pasted the framework part from me. I believe you are also very interested in it, and I will continue to introduce you to the wonderful im technology without confidentiality. In this article, I will explain the design of im-based UDP Communication Protocol (1) Have you used QQ? Frequently Used? Do you know how QQ works? Will QQ be split? As an im researcher, we often need to analyze existin

Several days ago, I constructed a DNS packet and checked some information. It seems that many of my friends have always had problems with the UDP packet checksum. I tried some sample code and there were also problems. So it took some time to make a successful example. In Linux, GCC passes and verifies the success. # Include # Include # Include # Include # Include # Include # Include # Include # Include Unsigned short checksum (unsigned short * buffer

ScenarioIf you need to use UDP to transmit large data, such as 10 m images, this breaks through the design principles of UDP. UDP is designed based on "datax", that is, it assumes that each packet you send can be contained in a single package. In addition, the maximum length of UDP data packets is limited by the basic

OverviewUDP is the abbreviation of user Datagram Protocol, the Chinese name is the Subscriber datagram Protocol, it is a simple Transport layer protocol for datagram, and it is a kind of non-connected protocol for processing packets in the network. UDP does not provide reliable transmission, it simply sends the application to the IP layer's datagram, but does not guarantee that it will reach its destination. Because

real-time audio and video domain UDP is the kingly The Transport layer scheme for real-time audio and video interaction on the Internet has two types: TCP (e.g. RTMP) and UDP (e.g. RTP). The TCP protocol provides 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 the correc

"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 a faucet in the reservoir. you can put the water in the pool through the fauc

TCP the difference between protocol and UDP protocol first, let's get this straight. TCP agreements and UCP Agreement and TCP/IP agreement, a lot of people are confused, has always been said TCP/IP Agreement and UDP the difference between the protocols, I think it is not clear from the nature of network communication! the TCP/IP Protocol is a protocol cluster. It includes a lot of protocols.

In the use of UDP protocol, we usually use other language tools to complete the work. So today we will mainly introduce the use of UDP protocol in Java. First, let's take a look at the basic concepts of UDP. The full name of UDP protocol is user datagram, which is used to process data packets in the same way as TCP pro
