Most of my real friends are in Java-oriented program development, but on the network I have a lot of friends are engaged in art design, web development, such as the work, however, most because they do not pay attention to, dry chores, low salary reasons, think that the wrong business, and stopped in this direction to study hard. In fact, it seems that the introduction of the industry is very low, and many practitioners, sometimes we worry about is not a development of the industry, yes, I think

entrepreneurs, but a certain area to create a surprising potential, the monopoly of technology and policy in the name of the original entrepreneur to quit, from the real estate developers into shopkeepers, the current straw-dominated monopoly institutions, it is not a few people to run these industries, So there is a serious waste of time and resources. SP, VOIP, IPTV ..., regulation is the right of the state, often by commercial organizations to tak

demand-driven technology development From the business requirements, the main requirements of 100G mainly from the backbone of the metropolitan area Network and data center business. With the continuous development of the broadband market, the number of users is increasing rapidly. At the same time, the bandwidth of personal broadband access is also increasing, each user 20Mbps, 50Mbps, or even 100Mbps of bandwidth, has become the domestic network development goals in the next few years. In r

more compact and convenient to carry. USB Wireless network card recommended: tp-link150m Wireless USB Card tp-link150m Wireless USB card tl-wn723n has exquisite small mini modelling, uses the advanced 11N wireless technology, the wireless transmission rate is up to 150Mbps, the connection is stable, the performance is advantageous, the function is practical, the price is cheap. In particular, it is better to be compatible with Internet TV, media Player,

There have been many reports of IP voice transmission (VoIP), network TV (IPTV) and video-on-demand on the Internet, as well as reports of other businesses being or are about to be launched by Network service providers. There has been little debate about the market demand for these services or the possibility of providing these services. The growing clout of emerging broadband carriers like Vonage has illustrated early market demand and market accepta

Nearly a period of time, many traditional UTM manufacturers frequently released high-end products-first SonicWALL release 4G products, after the industry's eldest Fortinet thrown 26G of the top UTM. Some analysts pointed out that the emergence of high-performance UTM is not a long time, this is a long-term security manufacturers brewing. Because with the performance of new UTM products more and more high, the future security Gateway market pattern is likely to change. Earlier, Gartner, the vice

First to the front desk development engineer's work next sentence definition: The use of front-end technology to achieve good communication experience. If you put the web in front of you, it's about the web, primarily the Internet, and you can include mobile networks and other media networks, such as IPTV, because the idea is consistent. Now it is very rare to find a WEB foreground developer that meets the skill requirements of graduating students. a

management of the second. The platform is a bit like a Spartan phalanx to the creeps, and the creeps have little chance. The key to the advantage of the platform is the network effect and the ability to attack two times. The net effect is that the more things you use in the platform, the greater the benefits. Imagine if one day, millet to the home hardware used to do all the time, from the TV to the refrigerator and so on, and each one is connected to the router and can be controlled through th

It is centered on a clean home screen experience and offers personalized recommendations and voice search capabilities that make it easy for customers to discover content.With Android TV, you can now create a grand and engaging atmosphere for your app or game content, and support interacting with game controllers and other input devices. Android also provide

the data rate, the shorter the working distance. Network technology can be used to expand the distance and maintain the data rate. Table 1 wireless services, applications, and specifications Figure 1 Relationship between data rate and distance of wireless technology Currently, most cell phone development uses g technology, such as CDMA 2000, GSM/GPRS/EDGE, and their variations. UMTS/3GPP 3G cellular phones and systems are constantly emerging, but they are still part of the total market s

principle of frequency division multiplexing. You can also use a phone number to access the Internet, avoiding the headache of dialing the internet. In addition, because data transmission does not pass through a telephone switch, you do not need to pay the telephone fee for dial-up Internet access when using ADSL, saving you communication costs. 4. fast and convenient installation: to install ADSL on an existing telephone line, you only need to install an adsl modem and a separator on the user

watching experience is to use representative applications and devices to measure the performance of videos and multimedia applications in place. For interactive videos, DF is maintained at a low level (for example, (less than 50 milliseconds) is very important, but this has little impact on IPTV, streaming media, or video on demand. The media loss rate measures the number of dropped packets per second, it is very important for high-quality videos. As

SetRERPAs a large-scale ring Ethernet deployment technology, Ethernet network protection solves problems such as weak protection capability of traditional data networks and long fault recovery time, it is an important technical choice and solution for carrier man construction. 1. Requirement AnalysisThe operator's IP Man plays an increasingly important role in the whole business operation era. On the one hand, it must comprehensively carry the Internet business, NGN voice business, ICT leased li

1. Metro access 1. High-speed access requirements Bandwidth acceleration is a significant feature of the rapid development of modern information society. From the operator's perspective, the demand for Household broadband acceleration, the emergence of IPTV operations, the construction of 2G/3G and LTE base stations and core networks, the expansion of business outlets and OSS systems, all of them propose IP, broadband, and comprehensive access require

traditional physical BRAS, but only implement centralized IP address control and Device Configuration Management, it is impossible to change the long release cycle of R D, procurement, and deployment of proprietary devices. Based on the integrated vBRAS of General X86 servers, even if the DPDK and Other Software Acceleration technologies are applied, from the perspective of forwarding performance, it is far from the line-rate forwarding achieved by a single board of Traditional Physical BRAS e

The application of CDN technology is more and more widely used by major internet companies. has become an Internet enterprise inseparable from a network operation and maintenance mode. What is a CDN?CDN leverages global load balancing technology to direct users ' access to the most recently working streaming media server, which is directly responsive to user requests by the streaming media server. If there is no content that the user wants to access in the server, the corresponding content is

), dynamically request bandwidth through the UNI interface, improve network utilization, and avoid the traditional maximum service configuration (port, matrix) mode, this reduces the router capacity and ports and improves the bandwidth utilization of the transmission network. ASON can allocate OVPN for connections between IPTV, NGN, Softswitch, 3G bearer, IDC interconnection, and public INTERNET service nodes to share the same physical transmission ne

of Ethernet "simple and beautiful", EPON has the widest range of optical fiber access (FTTx) users in Japan, South Korea and other Asian regions with its mature industrial chain and excellent cost effectiveness; with the same characteristics as APON and BPON, The GPON standard is favored by many operators in Europe and North America. Whether it is EPON or GPON, the upstream and downstream bandwidth is only 1G or 2G, but with the current interactive network TV (
