As the global IPv4 address is about to be exhausted in the next few weeks, the industry generally believes that the admonition of IPv4 addresses in advance will accelerate the development of IPv6. IPv6 is currently the only feasible way to solve the shortage of IP addresses. Since last year, telecom operators China Telecom and China Mobile have launched pilot projects for IPv6.
“The Father of the Internet†Wendun Cerf is currently the Vice President and Chief Internet Consultant of Google Inc. In the United States, he created the Internet Protocol “IPv4†in 1977, allowing global computers to connect with each other. An IP address is a series of numbers assigned to each computer, website, or other networked device. Each IP address is unique.
Previously, ICANN had predicted that IPv4 addresses would be exhausted in August 2011. Some experts believe that the emphasis on the development of the Internet of Things and the popularization of various intelligent terminals in countries all over the world are important reasons for the accelerated depletion of IPv4 addresses. The only solution is to replace the next-generation IP protocol: IPv6.
According to Zhang Tao, an analyst at Shanghai Securities, IPv4 can still be supported by the current domestic computer and mobile phone user retention. However, with the increase in network requirements for the Internet of Things, IPv4 addresses are obviously not enough. The development of IPv6 can also be considered as future objects. The development of networking takes the necessary network preparation.
The worldwide transition from the protocol of IPv4 to IPv6 has already started. It is reported that the 24 hours starting at 0:01 GMT on June 8, 2011 will be the first trial day of the IPv6 protocol system. By then, Web search engine Google Inc. and social networking site Facebook will take the lead in launching the IPv6 protocol system to provide users and engineers with a testing and analysis platform.
Since last year, China Telecom and China Mobile have started IPv6 pilot work in individual regions, including IPv6 protocol interoperability, base construction, and network management.
Analyst Liu Hongjun of Huachuang Securities said that judging from the current trend, the premature exhaustion of IP addresses will speed up the transition from IPv4 to IPv6, thus accelerating the replacement of existing routers and Ethernet switches with support from telecommunication operators, enterprises, and government LANs. New IPv6 products. At present, domestic listed companies ZTE and StarNet Ruijie have provided related equipment.
FUNCTION DESCRIPTION
Countdown socket has an AC outlet, the maximum can output 230 V16A of power, there are two control modes, that is, countdown off and countdown on. It is convenient to control the equipment which needs to switch off or turn on AC. improve the safety of the use of some equipment and save more energy.
SET TIMER
1,Countdown plug in the socket, all indicator lights red flash three times, at this time the socket has no output, for the normal state, into the countdown state. Click the button, the first red light up, the socket output after an hour off, and then short press the button can set the socket timing of 2 H.4H.6H.8H.10H.OFF.
2,Long press button 3s, all indicator lights green flash three times, at this time the socket has output, for the regular open state, into the countdown on state. Click on the button, the first green light on, the socket is closed an hour later, and then press the button to set the socket countdown 2 H.4H.6H.8H.10H.OFF.
3,Press button 3 longer S, all indicator lights red light flash 3 times again into countdown mode.
4,Select the required countdown time mode, the corresponding mode countdown lights up, start countdown until the end of the countdown time. The outlet that controls the output will start or stop the output.
5,After the countdown starts, the time indicator will change automatically from high to low until the countdown is over.
