ensures that the content serves the user's requests in an extremely efficient manner. In general, the content service is based on a cache server, also known as the proxy cache (surrogate), which is located at the edge of the network and is only "one hop" away from the user. At the same time, the proxy cache is a transparent image of the content provider's source server, which is typically located in the CDN service provider's Datacenter. Such architectures enable CDN service

to coordinate the daily work on a global scale, but as Zimmerman said, they adopted appropriate methods and procedures to ensure the success of the Ubuntu project. Ubuntu Development Team Zimmerman's project tracking has never been interrupted and ensures close communication among team members. This is a distinctive organization. First, although Canonical has offices in multiple countries, however, most of Zimmerman's engineers did not work in these locations. Zimmerman said: "My team has about

through the network, and the connection process does not require user participation. The UPnP specification is based on the TCP/IP protocol and other Internet protocols for communication between devices. This is why it is called "Universal"-UPnP technology does not rely on specific device drivers, but uses standard protocols. UPnP devices can automatically configure network addresses, declare their presence in a network subnet, and exchange descriptions of devices and services. Windows XP-base

Campus cabling is actually very simple: it meets the requirements of devices in the information, alarm, control, and other fields for physical layer transmission. In primary and secondary schools, technical schools, kindergartens, and other campuses, the campus wiring of colleges and universities is the most complex. The campus of a college is itself a small society, which contains almost all places in the city (of course, there are also, such as urban traffic, sewage treatment, weather forecast

communication, and give some suggestions to enterprises in terms of purchasing group telephone switches. There are various group telephone systems on the market, analog, digital, and network IP-based products. Which product is truly suitable for the enterprise's own needs? The following items must be considered: Cost factors: financial conditions, number of internal phone calls within the enterprise, overall cost, whether there are too many long-distance flights in the field, whether there are

/jitsi_2.2-latest_amd64.deb Run the following command for both 32-bit and 64-bit systems: $ Sudo dpkg-I jitsi_2.2-latest _ *. deb The above command will install Jitsi 2.2 in your system, and add the Jitsi source library to your system, so that it can be upgraded more easily in the future.

: Figure 1 RTP Header Format The important domains and their meanings are as follows: CSRC count (cc)Indicates the number of CSRC identifiers. The CSRC Mark follows the fixed RTP Header to indicate the source of the RTP datagram. the RTP protocol allows multiple data sources in the same session, which can be combined into a data source through the RTP mixer. For example, a CSRC list can be generated to represent a teleconference, which combines th

. B2bua can process the calls from the private network to complete NAT traversal. To adapt to all types of NAT environments, b2bua also needs to act as a media stream intermediary. This gives b2bua some features that the proxy does not have. For example, b2bua can end an existing call, but the proxy cannot. The operator often uses b2bua to avoid leaking its network topology. In b2bua, we can provide value-added or multi-point call control capabilities for point-to-point calls. Other sip servers,

Building Integrated Communication "A single voice communication cannot meet enterprises' daily communication and information management habits. "Xeim pointed out that in the future enterprise communication plan blueprint of the" Green Edition "of" fliggy Chuan Shu 2007 ", it is not only an enterprise internal communication solution, but also an integrated communication based on address book management. This communication method includes enterprise internal communication solutions,

Basic multicast knowledge: Common IP communication is performed between a sender and a receiver. We call it point-to-point communication. However, for some applications, this point-to-point communication mode cannot effectively meet the needs of practical applications. For example, a digital teleconference system is composed of multiple venues. When participants in one of the venues speak, other venues are required to instantly obtain the content of t

Tell me the truth: Have you ever sent back an email when you are on a teleconference (even if you are on a phone call with someone? Did you bring your notebook while you were in a meeting and pretend to take notes, but you actually went online without any aim? Do you have lunch or dinner at your desk? Do you call or even occasionally send text messages while driving? Even if you know you shouldn't do this!Why do 25% to 50% of people complain that they

when the network is very crowded. Application of UDP protocol Some readers may ask, since UDP is an unreliable network protocol, what is the value or necessity? In fact, in some cases, UDP may become very useful. Because UDP has a speed advantage beyond the reach of TCP. Although various security protection functions are embedded in the TCP protocol, a large amount of system overhead will be occupied during actual execution, and the speed will undoubtedly be seriously affected. In contrast,

What are the main benefits of the Video Conferencing System?? This cannot be generalized, differentVideo Conferencing System diagramThere are different solutions and combinations, and their respective advantages are naturally different. However, the benefits of the Video Conferencing System can be summarized as follows: 1Convenient communication anytime and anywhere: Since rhub integrated online video conferencing and teleconference, it has started a

Android phone system overview First, let alone all the concepts of Android to study the most basic descriptions of the telephone system. Our mobile phone was first used for phone calls, followed by a phone book, followed by PIM, followed by network applications, followed by cloud computing, followed by the idea that our mobile phone can do anything to replace PC. However, the basic functions of a phone call are as follows: 0) dialing, answering, hanging up, sending SMS, network connection, and

Development Background Our company is mainly engaged in the development of enterprise speech products, such as scheduling systems, command systems, teleconference systems, and call center systems. These systems share a common feature, that is, they involve calls, playing, sending and receiving buttons, and venue operations. Our business products are built on our softswitch system. The application servers of the softswitch system provide these service

solutions must be followed up and gradually supplemented and improved after the new technologies are introduced. This is a dynamic process. As the head of an enterprise, you must consider it carefully and never stop. Deployment now benefits, continuous deployment, and continuous benefits.
