Many units and companies set up their own local area network, but a newly built small LAN, a server, more than 10 workstations, using a switch as an access device, connecting lines to 6 types of lines. The main fault performance for the network in the computer transmission speed is slow, any one station on the server to copy a 100MB file, it should be 30 minutes. Even the adjacent two workstations are so slow. Failure analysis is tied to the followin

Recently has been running no problem FTP download program has been a problem, the prompt can not be decompressed. After analysis, I use filezilla manual download after decompression is correct, and my program use Apache.common.FTP package download that there is a problem, cannot decompress. Comparing the two found that the latter file size is large. Find data as follows, the code will transfer mode to binary transmission download, problem solving. for

1.1 Bandwidth The unit of bandwidth is "bit/s", which is the number of bits per unit time. We often say such as 100M bandwidth, the full name should be 100mbit/s, or 100Mbps. 1.2 How data is sent The transmission of data is generally through the following links: 1 The application will first write data to the memory address space of the process. Usually in program development This only requires a general Run-time variable assignment. 2 The application

In the current era of rapid development of the network, routers have a pivotal role. Because the router acts as the relay system in the network layer, it provides a routing and forwarding function of the data between the third layer network. Therefore, the router's function, role and basic configuration are as members of IT industry we must be proficient. Below, we will make a brief analysis of the router from two aspects: that is how to build a simple network environment in the experiment, and

Each time a data frame is received, a short data frame is used to confirm (transmission delay is ignored). If the one-way

Wen/Xu Jianlin In the field of real-time multimedia, real-time visual and perceptual display will have more extensive development space, while the basic core technology for real-time video transmission is the coding standard of H. In this paper, the author tries to solve the two problems of the core of the coding and decoding, one is the process of encoding and decoding, and the other is the structure of the code stream, hoping to help the people who

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

This article mainly gives you a detailed description of the reasons for the transmission speed of the wireless router, and provides some analysis. Here we also introduce some configuration solutions, and hope to read this article to help you. Many of our friends have found that our actual wireless router transmission rate is not as fast as described above. Why? Is it a false identification made by a merchan

For more information about relevant protocols, see TCP/IP study notes (8) TCP transmission control protocol Management of TCP transmission control blocks, set Interface Options, ioctl, error handling, and cache management involve the following files: Include/Linux/tcp. h defines the format of TCP segments, structure of TCP transmission control blocks, macro and f

In today's era of rapid network development, routers play an important role. Because the router acts as a relay system in the network layer, Provides a routing and forwarding function for data between the third-tier networks. Therefore, the functions, functions, and basic configurations of routers must be mastered as members of the IT industry. In the following, we will make a brief analysis on the vro from two aspects: how to set up the simplest network environment in the experiment, common si

uncertain, and the service recovery time is relatively long, which is a shortcoming of the recovery mechanism. Restoration is usually used for mesh networks to make the best use of network capacity resources. Both protection and recovery can adopt the reselect routing mechanism, but both have their own advantages and disadvantages. The protection technology has a short switching time, but the network resource utilization is low. The restoration technology greatly improves the utilization of net

The use of wireless networks is no longer familiar to many of our network users. However, to improve the transmission efficiency of the network, we need to study it in detail. Many of our friends have found that our actual wireless router transmission rate is not as fast as described above. Why? Is it a false identification made by a merchant? Otherwise, let's take a look at the article for details. Wireles

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

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

This article gives you a detailed description of how to configure the transmission of a wireless router, and analyzes its influencing factors and the configuration between network devices. I believe this article will help you. Wireless LAN, also known as WLAN, has become a networking method for more and more users. Wireless Network installation is very convenient and does not require rewiring. Therefore, it will not damage the original decoration of t
