Network transmission protocol and http protocol, transmission http protocolOverview: it refers to the constraints and specifications for communication between the server and the client. The data interaction between the client and the server is not disorganized and must follow (based on) certain specifications. Common protocols: A) HTTP and HTTPS Hypertext Transfer Protocol B) FTP File Transfer Protocol c) S

In section c #, we discussed the reliable transmission of udp packets (packet group transmission). However, the problem with the previous program is that the data is relatively large, A Message class has 2048B after serialization, and the actual data volume is only 50B, which indicates that the data is very effective. In this way, when too many packets are transmitted, the efficiency will be greatly reduced

(19th) Use block for message transmission and block message transmission Messages are transmitted between two classes, generally through a proxy or block. It is troublesome to write the proxy and the block is relatively simple. However, the block must pay special attention to the memory leakage problem, note that there must be weak references between self and block. The following describes how to use block

Event transmission and corresponding chain, event transmission chain Aside from the title above, This article focuses on how the system finds the control that needs to respond to the touch event when you touch the screen of your mobile phone, and the control's response to the touch event First, find the process to respond to the touch Event Control: the touch event is first detected by the message loop mech

Transmission of Struts2 and jqGrid parameters, and transmission of struts2jqgrid Recently, jqGrid was used in the project to display data. However, I have never understood how data is transmitted. In jqGrid, The rowNum parameter defines how many rows of data are displayed on each page, while in Action, the rows attribute defines the number of rows displayed on each page. Therefore, I have never understood

(usually home router), fill in the router password, click the blue button below, wait about 30 seconds, until the button becomes successful, if more than 1 minutes has not changed, Cliff is your password is wrong, or the account selected and password mismatch. 4.5 Successful people go ahead, return to the main interface4.6 Click on the network mode, for example, if the icon below the device online is a picture state, then the connection is successful, if the gray advanced bar in the rotation, i

Logu P2661 information transmission and logu p2661 Information Transmission This question has been done a long time ago. After a few months, I still don't know about it. First, consider each person as a node and generate a directed graph from the side that each person wants to tell him. Obviously, if a person is not on the ring, then it will never be able to hear his own information; if a person is on the r

In mina2.0, you can use serial transmission for connection, just like using TCP communication. Obtain Mina 2.0 You can download the latest Mina version. If you want to obtain Mina of other versions, you can check the developer manual if you have any questions.Prerequisites Prompt message:If you want to access the serial port through a Java program, you need a local library (. DLL or. so depends on your operating system ). mina is using rxtx.org this:

This article mainly gives you a detailed introduction of the wireless router transmission speed of the reasons, gave a few analysis, here also introduced a number of settings program, I hope to see this article to help everyone. Many friends have found that our actual wireless router transmission rate is not as fast as the product introduction, what is the reason? Is it a false identification made by a me

Wireless LAN, also known as WLAN (Wireless LAN), has become a more and more users of the networking approach. Wireless network installation is very convenient, do not need to rewiring. So it will not destroy the original home decoration, compared to the cable network, wireless network is much more flexible. In the use of the process, we found that although the WLAN does not have the trouble of wiring, and easy to use, but sometimes we will find its signal is not very stable, data

Video image transmission has the following characteristics: 1 requirements for small transmission delay, high real-time, 2 transmission flow, requiring high transmission efficiency; 3 allow transmission errors or data loss on certain programs. According to the above characte

In fact, some message/communication middleware has been encapsu

The development of wireless technology to promote wireless products to the home users, by building a wireless network within the home, can let us anytime and anywhere through the installation of wireless network card notebook and desktop to enjoy the joy of wireless surfing. But for most of us, often in the use of wireless products on the existence of more or less misunderstanding, today we will introduce readers to the error of transmission distance,

saving. Ethernet Ethernet Network: This is a local area network of online technology, but also the most widely used network protocol, it can through twisted-pair, optical fiber and other media to transmit digital data. LAN (Local area Network,lan, hereinafter referred to as the District network) refers to the small computer network in a certain area, such as in the Office, school classrooms and other environments. At present, most of the local area network architecture is in line with the IE

MTOM message optimization transmission mechanism is mainly used in the transmission of a large number of data, many articles also directly concluded that the use of MTOM file transfer efficiency. Why is mtom more efficient in data transmission than in other ways? is mtom really so perfect, what's the problem? When to use Mtom? These questions, this article WSE3.0

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 the correctness of the data. The sender can
