Article title: ADSL + MSTP build a comprehensive Metro transmission network. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In the face of increasing diverse transmission business needs, it is important for communication operators to establish a

Chapter Content Transports (transmission) NIO (non-blocking io,new io), OIO (old io,blocking io), local (native), Embedded (embedded) Use-case (use case) APIs (interfaces) A very important work for network applications is data transfer. The process of data transfer varies depending on which vehicle is used, but the way it is transmitted is the same: it is transmitted in byte-code.Java Development Network Program data transfer

In the next few years, carriers will use SDN technology to enable their man and wan to carry cloud services. Therefore, they need a multi-layer SDN architecture to optimize the routing network and transmission capabilities, this increases the flexibility, scalability, and efficiency of man and wan. Preface Cloud Computing technology has completely changed the design and operation of data centers (iDCs. SDN technology introduces this on-demand concept

Point of view 1: In the construction of 3G mobile transmission network, a simple idea is to build a set of independent ATM network for UTRAN, but ATM switching equipment is more expensive, and as a basic network, practice proves that it is not the best solution for other business. In addition, ATM has the problem of automatic configuration and recovery time of the whole network connection in the use of fiber network, and it can't meet the requirement

We need to know a lot about FTP. This includes its transmission mode. Here we will give a summary of the system. Let's take a look at all the FTP data transmission modes. FTP (file transfer html "target = _ blank> protocol) plays an important role in many network applications. Software resources are a very important resource in the Internet, and most of the various software resources are stored on the FTP s

Video conferencingIt is mainly used to develop software for transmitting audio and video data. During these development processes, the most core module is the transmission module. The performance of the transmission module directly affects the final quality of video conferencing, therefore, the selection of transmission modules is particularly important in video

Currently, many organizations have built internal lan. Most enterprise networks use twisted pair wires to connect to NICs for communication. Among them, twisted pair wires generally use 5 types of lines with a transmission rate of 100 MB. There are some differences between NICs. Many NICs adopt 10 Mbps/mbmps adaptive NICs, that is, the transmission rate automatically matches between 10 MB and MB. For such N

High-density and highly integrated OTN Wavelength-Division transmission SystemThis wave division multiplexing technology in the heyday, a variety of new technologies emerge. The goal is the same, that is to meet the network era of the operators. Long long ago, can only use CWDM coarse wave points, channel number is not enough to say, transmission distance is also very limited, line and equipment attenuation

Multicast routing is a good technology. It broadcasts data over the Internet. Unlike broadcast, due to broadcast storms, the router prohibits cross-route transmission of broadcast data. Multicast solves this problem. Currently, m$ software such as NetMeeting and WMS are widely used in multicast. Here we will discuss how to build your Linux into a multicast router.(Generally, gateways and routers do not support multicast data packets ). 1.

Before talking about the data transmission stage, we should first solve the historical issues left over. In usb_stor_bulk_transfer_buf (), row 406 has an interesting function called interpret_urb_result. This function is also from drivers/usb/storage/transport. c:265 static int interpret_urb_result (struct us_data * us, unsigned int pipe,266 unsigned int length, int result, unsigned int partial)267 {268 US_DEBUGP ("Status code % d; transferred % u/% u

Dynamic buffer for Network Data Transmission AnyChat has the buffer and file transmission function, which can realize the buffer and file transmission between the client and the client, as well as the buffer and file transmission function between the client and the server (added in V4.1 ). The buffer and file transfe

This article is a collection of online materials for further explanation. Introduction Real-time video transmission within the LAN has been widely used. Most of the local networks used for video transmission are wired LAN, because the wired LAN technology is mature, the transmission speed is fast, and the stability is good. However, if the video data volume is la

Real-time transmission protocol RTP 1. RTP protocol:RTP (Real-Time Transport Protocol) was originally used in 1970s to try to transfer audio files, divided into several parts to transmit voice, time signs and queue numbers. After a series of developments, the first version of RTP was released by a laboratory in the United States in August 1991. By the 1996 s of this century, a standard version was formed. Many famous companies such as Netscape claim t

Formula for the relationship between attenuation and distance of Wi-Fi wireless signal transmission [Indoor Location] Calculation of wireless communication distance1. DBM dbmv dbuv Conversion RelationshipDBM = 10log (pout/1 MW), where pout is the power value in the unit of MWDbmv = 20log (Vout/1mV), where Vout is the voltage value in the unit of MVDbuv = 20log (Vout/1uv), where Vout is the voltage value in the unit of UVConversion Relationship:Pout =

Digital video transmission is a communication method that people use vision to obtain information. Compared with other information transmission methods, digital video transmission is accurate, intuitive, and efficient. Due to the large amount of information transmitted by digital videos and limited bandwidth, the compression and encoding of videos, selection of

Android mobile phones and computers transmit data based on WiFi. Technically speaking, there are two main solutions: One is implemented through the FTP protocol, and the Android mobile phone is used as the FTP server during data transmission; One is implemented through HTTP. Android phones are used as HTTP servers during data transmission. Therefore, the technical difficulty lies in how our app implements F

expression and transmission of parameters in experimental instrumentsOriginal reason Description:In the different experimental instruments, the realization of signal transmission, in fact, can be converted to signal parameters of transmission. Therefore, the synchronization and refresh of each experimental parameter is the key to express the logic relationship of

With the rapid development of network information, the network affects all aspects of people, but the security problems that come with it become more and more prominent, so people's privacy requirements of network activities are more and more high. So the data encryption technology is born, the use of data encryption technology, to ensure that people in the network activities of data transmission security, while ensuring their own data and information
