P2P streaming is equal to IPTV2.0 it?

This year, noting that 2.0 becomes particularly popular, especially the time when 2.0 was still not popular to raise even more popular. However, I have to write P2P streaming media, in my view can really be IPTV2.0.

Let's look at P2P. The concept of P2P streaming media speculation from the start in 2005, a year down the light wind had more than 100 million dollars investment, the companies involved in this field up to dozens of much more. This is not the same P2P and BT, P2P streaming media in real terms is to P2P technology for video multicast, basically solve the problem of network video bandwidth, while dramatically improving the efficiency of the server. By P2P technology, the server send the video packets are often a lot of users with ip information when the information reaches a user's computer, the computer also been forwarded to the next IP, and so on. On the one hand the transmission of video information packets are not transmitted for a single user, each user they are communicators, like BT, video servers and bandwidth efficiency is improved efficiency, the calculation of the number of conservative 50-100 times, such as Tencent QQLIVE; the other hand, did not like the BT users occupy too much bandwidth, do not suffer from pressure from the telecommunications company, after all, a user can not and need to see two channels at the same time, the download may be a number of BT one or more threads at the same time, eat eat bandwidth, powerful. Thus, P2P video-on-demand solution to bring both the buffer, while not as crazy bandwidth BT, in order to find an excellent balance, and got rapid development.

As the broadcast reduces the user's interactive experience, so there carousel, a channel loop a class or even a video made and demand a similar effect. I started to pay attention QQLIVE from May's online, they have 20 million online since then to the current level of an average of 50 million online. If the count CCTV, pplive, uusee other video broadcast site traffic, the number of P2P live online at 300-500 million people, by the end of (New Year) is expected to reach 10 million online in the levels can be said of potential, market size more than casual games.

Turning back to look at IPTV.

IPTV (Internet Protocol TV OR Interactive Personal TV), also called interactive network TV, is the use of broadband network infrastructure to home TV or computer as the main terminal, set the Internet, multimedia, communications and other technology, and through Internet Protocol (IP) to home users, including digital television, including a variety of interactive digital media services, new technology. Many of the current description of IPTV, such as interactive, high definition, support for online games, and often high-definition television as a terminal, the current big push in the box is a real IPTV.

As for the IPTV license is very scarce, it is said in addition to other CCTV, Shanghai Media has also been a rather big box because no license was brutally halted. IPTV in China is actually the standard telecommunications and broadcasting in balancing interests, in the end is through the Internet to watch TV, or use the TV as a terminal to see the Internet, is the focal point of broadcasting and telecommunications disputes. So, although the license has been made, but the standards are still nowhere to settle down, a common argument is to triple play, broadcasting, telecommunications and mobile IPTV triple-play basis to talk about standards, it is also the interests of three parties has been unable to balance, so China has been stuck atop IPTV standards.

Radio and television sector is reluctant to allow users to use the Internet on television, so ads will be discounted, grand IPTV halt on the expected; the same time, radio and television also brings hope that the television through the Internet video, because it will increase advertising effectiveness , on-demand approach is not feasible, their bandwidth consumption and the revenue of this proportion. The emergence of P2P streaming, broadcasting and telecommunications to find a balance between. Can be very low cost to promote TV programs on the network, access to additional advertising effectiveness, play into the hands of median broadcasting sector. Can be seen over the past year, CCTV co-extensive and P2P sites, CCTV video of network is also growing, of course, does not include Tencent, the author seems to CCTV and Tencent's cooperation is sooner or later, after all, the result is win-win.

As such, broadcasting and telecommunications IPTV battle, have occupied a certain initiative. On the one hand, firmly controlled by the license, to play the game online through the TV IPTV form may not survive; the other hand, P2P and the content of radio and television units with large broad cooperation, this type into the Internet through P2P live video and impressive results .

Therefore, P2P streaming media, in my view be regarded as a IPTV2.0, regardless of their form of communication (full use of the user's resources), or its feasibility, IPTV has become the de facto standard, but from the effect point of view, have greatly promoted the television network.

I note, QQLIVE already there have been some high-definition video content, such as "Meteor Garden" has reached its Resolution 720 * 480 results have been very close to DVD results, while playing Shique and smooth, and QQLIVE of interactive features, but also make people feel that P2P streaming media in fact IPTV2.0.

I believe that P2P streaming media to help spread access to the Internet broadcast programs, but also will get its own rapid growth, to include IPTV2.0 standard is most appropriate that his.

SATA disk drives imperfection

Today, high-capacity series of ATA (SATA) disk drive storage system as a lot of mainstream products, almost all companies have the ability to deploy millions of these mega-capacity storage systems, and the price is reasonable. However, these systems reveal the existence of the SATA disk drive of a special, clear enough: SATA disk drives require companies to carefully control the deployment of storage systems environment.

High-capacity storage systems expose the SATA disk drive, there is a small flaw is its bit error rate problems. Bit error rate is very low, approximately 100 trillion bits error occurred only once. However, if the SATA drive to a specific bit error occurs, the storage system commonly used to protect data against loss of RAID technology can not detect the error.

While for small systems, it is usually not a problem, but as the ever-increasing storage capacity, the issues become more prominent. 10TB of capacity over the system, the specific data bit error probability of the lot. Capacity of more than 100TB system, its error is almost inevitable.

So the question into: a data bit can not be read correctly the results really affect you? Usually, this has not affected unless these systems to store duplicate data after deletion of data (data deduplication technology is the the fastest growing areas of data storage, a technology). If the data are data de-duplication operation, then read the correct bit for each data storage system is very important. Even if only just a bit can not read can lead to multiple files can not be read, as they may have to rely on a particular data bit to complete the reconstruction of the file.

High-capacity SATA-based storage system to solve many of the company's archiving and backup problems. However, existing data problem for SATA but would weaken their strengths, so use the SATA drives to store large amount of duplication of data is not in any case are the best, companies should make identification based on real situations.

PMP Exam tips

In fact, PMP exam is not as difficult as imagined, especially for N times experienced candidates for the Chinese examination exam to mention, the key is the methods and ideas.

I participate in on Dec. 7, 2002 written examination, before the exam, I did not own the end of the exam, because my leaving the country very well, the (until next semester to junior strong Guo Siji-free), plus of the reasons (IT industry, the world's most tired, most work overtime) is not more time to review, therefore, until a night before the exam, I boil lights night to 12. But when I get to do half of the exam, the basic feel very near the heart. Therefore, most of my exam questions are clear and explicit. Of course, and the rest on logical, and in mid-January 2003, I learned that he had Pass. So, if like me leaving the country and good friend, do not worry, is written in English, say that again, PMP exam in the face leaving the country is not difficult words.

I was in October 2001 that the PMP from the online business. Since I developed at that time companies a software project manager, was started from March 2002 to collect relevant information about PMP 鑰冭瘯 (Dushi free from the Internet gathered, this information is also grateful to those of friends) expiring in May from Beijing Hyundai Excellence bought three books (PMBOK in English and payment of teachers modeling problem). Usually use the little spare time to the following three books are roughly twice read.

To October, I attended the excellent modern exam training courses, through the 4 days of learning (should be 5 days, the last day of the company I was captured, resulting in my not heard about the PMP exam ethics chapter test was the worst, with 29 items of the 20 items, this is something), my mind clear about many, especially for gold teacher lectures to various aspects of channeling up points, so I've learned to read in all their comprehensive knowledge points are isolated.

After listening to King teacher training course after the exam, I looked again three times PMBOK (in the Combination of the British version, there is no Chinese version I looked at strenuous), and Modern excellent exam simulation questions to do it again. Originally planned 10 days annual leave, exam, please, go all out to Notes, but in the end or just stay at home full 4 days on the "torture chamber", but still good, eventually passed.

Personally, I think, throughout the review period, the biggest help to me in addition to PMBOK (Chinese, English version), the exam is excellent training for Beijing Hyundai and their simulation's question. Read several times as long as the PMBOK, the head impact does not have a lot of deep stuff, but there are many knowledge points PMBOK in simply did not say or did not elaborate, such as some financial, such as probability and statistics knowledge. The outstanding issue of gold in the modern teacher's "exam simulation questions," all have very detailed description and list of relevant examples. Also, this test (December 7, 2002) has a lot of questions are the book's original title (or basically the original title).

Well, another pile of nonsense, the distribution of this examination of the exam, said, and maybe we will have some help:

Group Process Area Number of Questions
