Chapter observation SNS technology and services
SNS when compared with these applications is matchless
1. Traditional instant messaging (talk):
QQ, MSN, etc. are based on the centralized management of network model, in the backdrop they need to have thousands of servers namely are assigned to users in txt chat and consumption of resources not large (such as QQ1000 Wan concurrent users, 10,000 servers, 1GB bandwidth is already ample). So the way server-based, chat application does not seem much of a problem.
SNS does not require any server.
2. Video and voice communications:
QQ, MSN and so did not succeed in entering the market because a large cluster of servers is laborious to mainly manage this type of traffic volume,
Nike Shox Nettbutikk, complex multi-process **** network vehicle. On the inverse, SKYEP with P2P technology,
Nike Shox Sko Norge, but succeeded in entering the voice market, and almost without any server.
SNS SKYPE the transportation speed is eight times faster than, because the SNS is relatively SKYPE, the advantage of P2P is not a simple voice connection, but to cultivate the bandwidth of the network speed. So, SNS voice quality will be much higher than SKYPE. SNS is a platform, SKYPE voice communication is a P2P software.
3. Online Game:
grand business of the game is a centralized server network game, a more progressive server and bandwidth resources. Grand success of this company is heavily dependent on China Telecom bandwidth resources to assist pre-planning.
in the SNS-developed online games, online game developers do not need to solve the centralized server and bandwidth for the input costs. Their only need is to have a bank charges interface.
4. Competition with GOOGLE:
GOOGLE quest the information on the site, SNS SNS network in quest of personal promulgating is to share information, merely can still use the SNS as the pre-build a GOOGLE search, later the user fast access to search engines . This depends on the SNS grid computing model.
5. Compete with EBAY:
aforementioned SNS SNS ought be used only stores the transaction application instance. SNSP2P mart is trading to encounter the needs of whichever individual alternatively SME services. It traits face to face, you can buy me entities and communicate with me, I can visit your store instantly communicate with each other. This ambiguous relationship among the store and clients, customers are either consumers and dealers of peek characteristics.
EBAY auction system, although such a concentration of 24-hour online, but more like a commodity Yellow Pages. The real transaction was interesting to face bargaining. So EBAY this website, in counting to providing more servers and more bandwidth, they can charge what it charges sellers landing goods? Because the SNS market, the trading server does not need anything to control the bargain of the two sides need only a honor to how to ensure completion of the sale, to realize this task is not to depend on EBAY, or SNS, but on the existing banks and warranty companies.
SNS bring new applications
1. SNSP2P Network TV:
country has about 150 massive companies to provide in the field of network television, including MS and other giants. There are more than 5,000 sites have begun to test the network television announce.
According to the current server / client model of the Internet in the last three years, if the carriers will focus on the bandwidth can not be a premonitory cost rebate (100MB dedicated bandwidth from 56 million / year down to 50,000 / year), and the client bandwidth is generally hoisted to 4MB, the user can not actually see network television. But by SNS, the user will see 200KB / S-class network television. This criterion is the current network television business to absence to accomplish. And no need to change any existing SNS infrastructure.
server-based networks, notwithstanding you can purchase a lot of hardware and software resources to empower the application of network TV. However, this cost is passed on to clients to work. Hou Ziqiang, Chief Scientist of China Netcom, said: This is completely impossible to network television model, P2P networks absence network TV can.
2. SNSP2P charge of content:
users who share pirated, so a similar multi-point download BT P2P network P2P network has seen the application interesting. However, those specialized anti-piracy BT website will close. This brought to the SNS has a huge market opportunity, because the SNS can charge the content of, and for those with valuable content providers behalf, without setting up surplus servers and bandwidth. For example, the cost of downloading a song is a dime, then it is naught in the SNS.
China and the U.S. lawful career has been pronounced guilty of offering pilfered content, it is now considering if to remove from the network technology such as BT's time. The SNS network can administer the content of digital rights.
3. SNSP2P Profile:
aforementioned personal network radio and television stations are SNSP2P a personal information center for the application example. Through the SNS, as anyone can have a web server-like ability. This completely changed the logic of the Internet needs a server, the server and the bandwidth is no longer centralized and not hinder the inspired and IT technologies is the money power.
This is in addition to SNS, the application is not apparent. SNS users can now have their own music station. Their personal information can be in the center of application development has introduced 6 months.
4. SNSP2P enterprise workflow Center:
Every business requires only a simple configuration of the SNS, we can successfully create their own workflow P2P networks. And their management of the core can be self-enclosed, it can be open. Because there is no central server, they only need to manage their own applications to control. This greatly depressed the need for enterprise management of hardware and network management investments.
5. SNSP2P based hardware market:
while the telecommunications backbone network workers realize the power of P2P networks,
Nike Shox Norge, they will begin to transform their current building of the server-based infrastructure. P2P networks such as providing movie phones, P2P network router, P2P networks or even mobile phone network. This will be the carriers of these desperate to bring new revenue outlets.
In truth, companies such as INTEL 1998, began as early as the devise of SNS-based P2P networks such hardware devise. Their goal was quite remove,
Nike Shox Turbo, if the chip can generate P2P, then they will not fail because of Moore's Law, but no food. P2P is a unattached chip called the Pentium processor into the 100 million 1 billion in P2P collaborative computing the Pentium chip. The emergence of this chip, will fundamentally solve the computing capacity of a unattached piece of equipment is not the location. People no longer trust that the future buy of more advanced chips to obtain faster processing speed, but to buy INTEL costing, purchasing as much as the degree of power.
SNS-based network technology for large-scale network applications, the ancestor of the special conveniences of
Internet is completely based on a easy delivery network of naval networks, the Internet was easy and lovely father, communicate with each other to share resources. However, only mainframe Internet between my dad has this competence. To this is shrieked the Internet epoch, human forget its father. Why? Crazy because advertisement companies enter this market, simply do not consider the underlying network security and efficiency. It is their roots back to the time.
2004 April, October, November, January 2005, March, most users of the QQ and MSN instant messaging network deadlock occurs worldwide accidents, the two companies appearance of the explanation is: virus attacks. In fact, the server-based instant messaging network regardless of how reinforcement,
Nike Shox NZ, only more complicated and more secure. Because they are the center of the network, is their server center. Hackers or center of the machine deadlock, will result in all unavailable.
2005 年 4 August, China Telecom, a extensive network of paralysis for 5 minutes. Some explanation is that the virus attacks the backbone routers.
As Shanda games, PK not people, it is commonplace.
this problem is the famous monograph of the network: the network application server model more warmhearted, the more close to collapse. That is from methodology to train, now based on a centralized server applications are difficult to win large scale development. Experts have predicted: the collapse of the Internet in 10 years.
those based on 1G, 2G, 3G mobile phone network closed, if they want to be outside in addition to voice services, will also learn the courses of the current server-based network.
the 1960s, this unity is mansion the Internet computer pioneer father's mind, now back to the network ecology of the times. That is, the server appears to facilitate the management, very fragile, is **** fragile. Distribution network appears to emancipation, not management, there is better management, that is **** managed.
heavyweight associated with SNS comments
1. American Communications ****** PRESIDENT: I first saw this P2P without server SKYPE VOIP (Internet phone), I knew it was all over.
2. SUN Chief Scientist: P2P WEB end of the Internet, we all need P2P.
3. Chief Scientist of China Netcom: no P2P, no future.
4. GROOVE founder (sometime Lotus Software Technical Director, LOTUS inventor): P2P makes me more incited.
market is large and SNS-related events:
1. In 2001, NAPSTER introduced centralized management of P2P music sharing software, within three months 500 million users online.
2. 2002 NAPSTER company closed by U.S. tribunals, some users are using NAPSER ****.
3. In 1999, INTEL announced the use of P2P technology, and fabrication and P2P narrated hardware.
4. In 2004, SKYPE concurrent users exceeded 1.5 million, only eight months.
5. In 2004, QQ concurrent users exceeded 10 million,
Nike Shox Torch, almost each company wants to have their own instant messaging software.
6. In 2005, the SNS during inner testing, more than 150 people have queried how the co-founder of SNS, more than 30 companies want to collaborate now, more than 10 large companies can buy, founder of consulting SNS SNS.
SNS technology history, philosophy and the founder
SNS development of the found model along Zhang Chunlei Zhang Jinsong and two brothers in a private house in Beijing began the conception of period 1995. They must dream a more powerful private computing power and bandwidth of the web, how to make the so-called small devices with each other to share computing resources. That is, dispensed web modeling.
10 years afterward, SNS has amplified over the founder of two successful based on client / server architecture of the undertaking networking software, which is based on the internal ERP system, Internet-based model of monetary thinking and trading system of go. The two founders of the software so that SNS profoundly know the strengths and disabilities of today's Internet.
founder of philosophy from the start SNS, SNS, founder of the network should be to establish information that the individual-centered, rather than **** for the center. Created by mankind for thousands of years of invaluable information to both individual-based, masterly, scientific invention, transaction information, etc., are all unique individuals in the behavior. Now the Internet is more like a server-based network is the machine age, is the company to control information stream the way the server in enslaving the individual creativity, is a new television network only.
SNS founders achieved that: independent of a computing device, its capability is forever restricted. The power of the network is endless, the opener publish is how to make these separate devices dispersed in the network can mutually share their hardware resources (computing power and bandwidth). This problem is solved, a fashionable application based on individual creativity can occur ahead the development of sustainable access.
in the background provided by some of the distribution network calculating technologies such as GOOGLE in the background, a dedicated distribution network to provide search technology, they can already use an ordinary personal microcomputer can search universal sites, and have been successful. If we had, GOOGLE using distributed technology is not the initiator, but the use of large mechanism and large-bandwidth reach to vocation development, GOOGLE can not support today.
e-mail server such as a simple distribution network technology, but also a magnificent success. Basically, the server that the end of the network, to a large extent are distributed, layman's terms is the P2P. But they did not use the so-called distributed computing client machine, the user of the machine on.
SNS starting point is from the user's machine to create an unprecedented distribution network. In this network, via development and application of the incipient founders of the fancy of SNS success.
the history of science and technology, technology namely not a heaven. The author of SNS aboard the elbows of monsters apt look the future.
P2P software is currently the guiding cause of ardent programmers. Because the P2P software is network-oriented programming, instead of a PC-oriented programming, such as developed as WINDOWS. P2P requires a more powerful imagination, and ability to use numbers more powerful, more disposed to so-called purely technical. But see further realized that P2P networks will change the way we use all the ways.
SNS and closer to opponents GROOVE today compared to the advantages and drawbacks at a peep, as usual:
SNS fire applications with the reality of the state (already released 1.1 version), which is alike GROOVE . However, the development of SNS does not GROOVE500 people power, the specific application development capabilities than the weak. However, SNS has a JXTA community strength, innovation can be compared to the non-GROOVE.
GROOVE for the enterprise market, each authorize must collect the money. From the lowest to the maximum 100USD 1200USD. SNS is free.
GROOVE too need to have a similar server in their network resources, because it does not solve how to faultless the WINDOWS the P2P development. The problem lies in WINDOWS, rather than GROOVE. However, SNS JAVA-based development, there are no obstacles on the foundation of the network (which is the chief cause for success of JAVA).
SNS platform breakdown operation, tin now nearly entire operating systems, including the so-called clever call operating system. GROOVE is only a service because Microsoft productions.
and SNS-based technology-related products have SKYPE, BT, GNUTELLA, QQ. One SKYPE (almost not server), BT, GNUTELLA is truly distributed computing network, they will not server. QQ instant messaging software such as the use of P2P technology is creature tried, but its infrastructure is highly dependent on the server, can not become a true distributed network, they used the power of P2P technology is to retention a mini money.
