1. Introduction With the increasing demand for mobile communication systems, currently, 2G, 2G, and 2G systems and 3G systems that have been put into commercial use cannot meet the increasing high-speed multimedia data business needs of modern mobile communication systems, many countries have invested in the research and development of 4G mobile communication systems. This article will briefly introduce the main technical features of 4G mobile communication systems, and discuss the key

The rise of server virtualization and cloud computing technology does not mean that we no longer need good IT Disaster Tolerance planning, as well as the tape technology that may be used in these planning. The following are some disaster tolerance techniques mentioned in JonToigo's keynote speech at its StorageDecisions conference. As the CEO and Management Partner of ToigoPartnersInternational, Toigo believes that cutting new technologies and budgets

. Perimeter security defense for important facilities Military locations and defense facilities: such as troops, airports, military ports, missile/rocket launch bases, radars, and communication sites; Important national economic facilities: power stations, substations, Wenbo pavilions, financial warehouses, and stadiums; Defense of inflammable and explosive places: oil depots, gas depots, Oil and Gas Storage Tank areas, and explosives depots; Important defense sites: prisons, schools, reservoirs

then forwarded to the mobile node through the home proxy tunnel. (5) the mobile node determines that the communication peer does not have its own binding cache based on the IPv6 Group forwarded by the home proxy. Therefore, it sends binding updates to the communication peer to establish binding. (6) After the mobile node leaves his hometown, the home network may be reconfigured, and the original home proxy will be replaced by other routers. Mobile IPv6 provides a "dynamic proxy address discover

First, we need to know the basic principles of the Performance Comparison of the routing technology. Q: exchange network routing technology. A: exchange is the development direction of network technology. The routing technology is an important part of the exchange network. The correct choice of Routing Technology in the exchange network will directly affect the overall performance of the network. As a result, the routing technology is increasingly valued by manufacturers and network designers. P

Compared with other network management technologies, the multi-layer switching technology has distinct characteristics. Here we mainly analyze the advantages of multi-layer switching technology, so that you can have a deeper understanding of it. With the rapid development of Internet/Intranet deployment and usage, the computing models of enterprises and consumers have changed significantly. The market's demand for network management and data stream ex

This article describes the advantages and disadvantages of three Linux server monitoring technologies, including SNMP proxy (client), SSH, and private proxy (client) installation. The powerful functions and beautiful interfaces of the Linux system make many enterprises use the Linux system as the server. The following is an introduction... this article describes the advantages and disadvantages of three Linux server monitoring

In the past, vrouters and hubs were often used in the network, but now many networks use vswitches. How do I face the challenges of routing networks and switching technologies? Currently, vswitches are dominant in the network market, because of their high cost effectiveness and flexible structure. They can be flexibly configured with future application changes. Numbers can best indicate problems. In a vswitch with a 100 Mbps uplink, the cost of each 1

Have you ever wondered how to make your wireless network more secure? Some people say that a large amount of information about Wi-Fi security can be found on the Internet, such as using WPA or WPA2, disabling SSID broadcast, and changing the default settings. However, this alone is not enough. We will share with you four advanced technologies that make wireless networks safer. 1. Switch to enterprise-level encryption If you create a WPA or WPA2 encryp

positive or negative events.In the past, it may be traced back 15 of years that commercial applications must not stoop to the fixed methods, structures and interfaces (such as relational databases) used in the computing technology that was available at that time, and the information had to be inserted and stored statically before the user could parse and respond again. The common implementation of the traditional JEE (Java Enterprise Edition) application server is to look for an initial request

Occasionally, I searched the internet and thought I was really inferior to anyone when I saw some very popular technologies. I always hoped that I could be as knowledgeable as these cool people, however, I don't know where to start or where to start. In fact, I feel that I am still working very hard. I will learn some technologies or research something as soon as I have time. In particular, a technology lik

WebDevelopers often need to update their knowledge and learn new technologies, if they want to continue mixing well in the Web development field. The following shows seven new web development technologies. As a web developer, you need to understand, familiarize yourself with, and learn the technologies. 1. css3 media queries Currently, the emergence of a large

the first time, it will save the PHP intermediate code in the memory of the Web server, and then respond to the subsequent request with the "compiled" version. This method can indeed improve the performance of the application, because it minimizes the disk access volume (the code has been read and parsed ), the code runs directly in the memory, greatly improving the server's response speed. Of course, the cache module also monitors changes in PHP source files and caches pages again when necessa

circuit technology enables the switch to run with more ports. The port cost is lower than that of the traditional bridge. Several exchange technologies 1. Port Switching Port switching technology first appeared in a slot hub. The backplane of a hub is usually divided into multiple Ethernet segments, each of which is a broadcast domain, networks do not communicate with each other. After the master module is inserted, it is usually allocated to the net

Add By zhj: the translation is slightly modified. At the time of the original article, Instagram was not acquired by Facebook. After reading it, I felt that the three backend engineers of Instagram were awesome. Three people can handle 14 million registered users. However, on the other hand, we can also see that the three actually use off-the-shelf technologies, at least not from the article. Of course, it is difficult for three people to make innovat
