aaaa transmission

I am very sad to write this short article about some understandings of network transmission. How to transmit data quickly between multiple nodes was just optimized from the perspective of data transmission, it would be a pity to give me another chance... Let's talk about the following points: first, we should try to improve the degree of parallelism, and each node transmits data to other nodes that do not h

Asynchronous transmission mode, also known as cell relay. An ATM adopts a connection-oriented exchange mode, in which the Unit is credit. Each cell is 53 bytes long. The header occupies 5 bytes. ATM is ideal for implementing various QoS, supporting both connected businesses and unconnected businesses. Is a model of broadband ISDNB-ISDN) technology. Asynchronous transmission mode (ATM)ProtocolSet to establis

AMI encoding1 yards is usually called the pass number, 0 yards is called the empty number, this is used in the early telegraph communication in the name. From the morphological perspective, it is a three-state signal, so the AMI code is a pseudo-three-in-one code.First, the coding rules:0 in the 0 transmission code in the message code+ 1,-1 alternating in the 1 transmission code in the message codeFor examp

Communication between people is now mostly done through instant messaging, and these tools have the basic function of file transfer. Then use this function after two development by using Instant Messenger, the following is an example of the Anychat interactive development platform of the leading audio video technology in China, which realizes the file transfer function. Anychat supports the file transfer speed limit feature since the Anychat SDK version V4.1.0.1. By default, anychat file transfe

SSH can transmit data by encrypting the online packets. SSH can be used to encrypt all transmitted data, and no useful information can be obtained even if someone intercepts the data. At the same time, data is compressed, which greatly speeds up transmission. In short, the use of SSH ensures that data transmission is secure and the transmission efficiency is high

First, the storage, transmission and processing of image dataImage data can be stored in external memory, display memory or computer memory medium 3 medium, different storage media for different purposes. The image is stored in the display memory to show that the displayed image intelligence is viewed in the boot state, and disappears after the shutdown is called a soft copy. To facilitate fast access to image refreshes, the data in the display memory

GPRS data transmission plane Compared with GSM, GPRS reflects the characteristics of group exchange and group transmission, that is, data and signaling are based on a unified transmission platform. As shown in the figure above, the Protocol structures below the transfer layer (LLC) are the same for data and messaging on Several Interfaces passed by data

TCP and UDP transmission principles of Socket communication in Android 1. Socket Communication Android can communicate with the server in two ways: Http and Socket. The biggest difference between the two is that the http connection uses the "request-response method", that is, a connection channel is established during the request. After the client sends a request to the server, the server can return data to the client. In Socket communication, TCP/IP-

Network programming: UDPto understand network programming, you first need to understand what a network is (understand):Network definition: The network refers to the independent function of multiple computers through the communication line, in the network management software and network communication protocol, the realization of resource sharing and information transmission virtual platform.Popular can be understood as: is the two or more devices conne

Introduced The OASIS WS-RX Technical Committee recently released a public preview of the WEB Services reliable message transfer (Wsrm,web services Reliable Messaging) 1.1 specification. As the Chairman of the Committee, I feel it necessary to make an introduction to WSRM and its norms. This article takes WSRM 1.1 draft four as the subject. The WSRM specification allows two systems to implement reliable transmission messages. The goal is to ensure th

Basic vro configurations are easy to learn, so I have studied vro configurations and detailed explanations of data transmission. Here I will share with you, hoping to help you. In today's era of rapid network development, routers play an important role. As a relay system in the network layer, a router provides the routing and forwarding functions for data between the layer-3 networks. Therefore, the functions, functions, and basic configurations of A

First, we will introduce the cache hierarchies on mainstream GPUs: Level 1 cache: Local Texture Cache Level 2 Cache: local video memory Level 3 cache: AGP memory Texture data, preferably the closer to the GPU: Level 1 or Level 2 cache. VBO and PbO in OpenGL adopt a flexible mechanism to solve this problem. However, the closer the data is to the GPU, the more difficult the CPU is to access the data. In this way, if the CPU needs to change the data frequently, it is best to store the data in the

Binary XML has aroused a lot of discussion. One reason is that relatively compact transmission formats are needed, especially for Web Services. The existing ready-to-use solution is compression. This tip illustrates how to use compression to prepare XML files for transmission in Web Services.In the discussion of XML, the view of binary XML has always been heard. Due to its traditional text and the rules req
