Liu Yunjie Chinese Academy of Engineering: "Soft exchange untimely"

As the IMS and HSDPA, HSUPA rapid development, makes the soft exchange value and life cycle greatly reduced. Softswitch untimely, to this point, operators should be fully estimated.

We are talking about NGN, NGN we have defined four areas: the first is based on packet switching technology, most of IP technology; the second is to provide telecommunications services, including all business, including, for example video services; The third is to separate hosts and operational control, and bearing all the bandwidth to provide a QoS guarantee requirements; the fourth is to ask the user can select any operator, not the subject of a certain operator. Should be based on the definition of these four aspects, in accordance with the objectives of such direction to the NGN.

NGN concept is the development of the telecommunications industry for many years the concept of accumulation is the goal for many years. Background is a long time, the network is the traditional telecom industry, one a business network is separate, but the industry has been pursuing a goal, can you separate the network into a comprehensive unified network platform to evolve. 70 years from the last century the pursuit of ISDN, to the 80's B-ISDN, then 90 years of the Internet, do not achieve the intended purpose. Now we talk about the NGN, the ultimate goal is to achieve multi-service, to achieve network convergence.

To achieve this goal, from the perspective of the telecommunications sector has to face and solve four problems: the first is the load problems; second is how to achieve network bearer network integration; third, MAN and How to access the network in accordance with the concept of NGN deployment; the fourth is how realization of NGN network architecture business goals.

What to do with technology bearer network, which is plagued us for years, because it can provide routers and ATM bearer network is the two technologies, but the two technologies do not adapt. In addition to the other two technologies, there is no third technology? Router technology why not? In short, the time when the network failure, network routers and other nodes in the network took place less than perceived status, this is because the router does not test, no interaction network information function. ATM's problem is not the ability to handle IP, and now more than 90% of applications are all IP applications, so we come to a dead end that the ATM is gone, in fact, if coupled with IP-ATM processing capacity, or have applied prospects.

The second challenge, how in a variety of online business hosting? Solutions proposed by the industry through the design of the logic of virtual private network over the region, each private network has a business, every business has its own routing table, have their own QoS level, and between these logical networks mutual isolation, which would address reliability issues. This program provides a way to integrate the three networks, it is all in the pursuit of goals.

The third issue is to realize NGN, how to achieve integration in the MAN architecture? MAN to make some new architecture and standards, no new structure and standards, MAN will not meet the requirements of the next generation.

Now in the access network side, we note that the problem is UMA, is license-free mobile access. The question now is, cable network bandwidth is unlimited, bandwidth capacity increases, but the wireless network bandwidth is always limited, because by the frequency limitations. But the wireless applications from the current view of almost unlimited, and now wireless applications varied, scenic side is fine, we all moving in mobile aspects of development, this is a reality. This is a great contradiction between the two: one is the limited resources, the application of infinite; one is unlimited resources, applications, has many constraints. How these two technologies together like this is always the issues of foreign and domestic should follow up studies in this area.

Fourth, on operational integration issues. IMS and softswitch is now in the country yet there is no unified understanding and views, of course, very difficult. My view is that IMS softswitch with the biggest difference is that, IMS can provide more services for the application. Softswitch every business should have its own set of design, IMS is not only in the planning can be unified, in fact, can be done in the QoS context unification is not only a bearer and control separated, you can separate the user interface, all access into the way, whether mobile or fixed way means can be achieved. IMS data can also be centralized. From the business point of convergence, IMS has great appeal and advantages. In addition to providing voice softswitch outside the big problem is in the application have great limitations.

Softswitch and IMS architecture choice between, is the troubled telecommunications company, in doubt, look unclear. However, IMS will replace the soft switch, which has a global consensus.

As the IMS and HSDPA, HSUPA rapid development, makes the soft exchange value and life cycle greatly reduced. For this, operators should be fully estimated. My personal view is that the soft switching untimely.

Softswitch is five or six years ago, emerging technologies, just five or six years ago, the telecommunications, IT industry downturn, continue to go trough the process, which makes the soft switch has yet to push the use of, or application is not universal. When the IT industry began to rise from the bottom, when, IMS rapid development, makes the soft-switching will be relatively short life cycle.

Operating companies in the choice of soft-switching and IMS, if you consider the deployment of IMS architectures, requires network support HSDPA and HSUPA, and the related QoS mechanisms. Because IMS is not on, is not the standard into a mature, standards will change the future. Not on HSDPA, HSUPA, the IMS may, however, can only provide part of the business, can not provide all of the business.

In addition, IMS support for VoIP and multimedia services, the IMS is certainly risky, but the risks and benefits is the co-existence. Assess the risk, if the IMS can be successful, avoid the soft switch investment. Because these investments can not be completely smooth transition to IMS, there is always some equipment can also play a role though, but do not throw no good, do not throw good. If you do not have the above conditions, soft switching, then we must take into account the smooth transition to the IMS feasibility and long-term coexistence of the problem.

Fixed network operators to replace the current soft-switching PSTN is so urgent? I personally doubt. PSTN is now applied very well, did not say growth may be very large, there is no need to use new technology to replace. Now the problem is that PSTN can not provide more new business, I think that the provision of new services with IMS softswitch more than the advantages. With the maturity of IMS, network and application will do more.

So I think that telecom operators and equipment manufacturers should spend more energy on research and development of the use of IMS.

And this time, my wife and I are very dangerous, and blood are less than half, and pulled up on the ground if another cure, together with blood, as we have set, and I so he ordered a DP medicine, put a burst ( not used this stuff before it), because everyone in the pile of cut, and on the sword and I just put a anti-dust + crimson before to now, I see the cure not care for her blood increases, transient I put a burst on the stoop, "H", healing and blood is running all get on the ground of the Sword Star

I have stunned for a while, my wife asked me how they had ... ... a ghost that shattered so fierce that oh

Qi Cheng white-collar workers willing to work part-time outside the "private activities"

Eating bowl, and thinking about everything. According to ChinaHR yesterday for the 1463 business within three years of experience investigating white-collar staff of the situation shows that 7 adults willing to work part-time outside the "private activities", and they almost all want to muffled rich, not a trace of the unit revealed a message.

26-year-old Mr. Tang, a consulting firm in the research and analytical work on his online shop in Taobao over wage income. He sold food to lose weight mainly because of chance was a special purchase channel, so that product prices lower than 10% of the market, so business is very good, about average monthly fetched 35,000 yuan, profit nearly 10,000 yuan .

"Sideline" well run, they must invest considerable time and effort. Therefore, the part-time personnel manager who has been regarded as taboo for the workplace. However, in order to have a monthly "quick money", 7 percent of the people that can secretly get dried up is the "investment partnership" and "on-line shop." However, most of them still have scruples, nearly seven adults and colleagues said the secret to the unit.

Survey, when the sideline income over wages, only 8.8% of the people will insist on positions in existing companies to focus on. Therefore, personnel ChinaHR Research Center, warned the young white-collar, professional and long-term vision should be. Professional experience is limited, relatively low wages is inevitable, but this time the young people growing up in the workplace, a critical period. If too seeks profit, career planning resulting chaos could be the next promotion rather narrow road.

Dell's alliance with AMD vortex effect caused

Dell and AMD is just the beginning of cooperation, and perhaps not end.

"Dell AMD marriage of two things: First, do our business better, because Dell's accession to the user's acceptance of the AMD will be higher; Second, our profit thinner, because the Dell AMD together came in, prices will be held down. "Sun server channel business associate chairman of Beijing Dong-Hui Wang Rong commented. Wing of the Alliance Sun servers in China, one of seven channels, while the Sun is AMD's die-hard supporters, the server does not use Intel processors.

May 18, Dell released the company earnings call made it clear that Dell will be in its high-end four-way servers using AMD's Opteron processors, expected to launch new products later this year. Although the marriage between Dell and AMD's "scandal" has been seething mass of more than a year, but the news was confirmed, the industry is still a shock.

22 years, Dell has been a fan of Intel. Even rival IBM, HP products have on the server using AMD Opteron processors, Dell is still unmoved. The Dell has finally turned to AMD, its underlying causes and impacts of all food for thought.

"God" hand

Dell and AMD after all, marriage is ultimately a "God" in the hands fiddle. "God" is the user's needs.

"For users, not to mention like AMD, Intel does not like. Merely provides an alternative AMD, Dell can not give up this part of the user." CCW Research senior analyst Guo said.

Some analysts believe that, AMD Opteron processors, both in performance on, or power consumption, are better than the Intel Xeon processor, and AMD has a price advantage. On is known as "price butcher's knife," said Dell, the AMD "inexpensive" products shut out, does not seem wise.

According to the latest Dell filing shows the first quarter 2006 sales of 14.2 billion, compared with the previous quarter fell 6%, but up 6% over last year; first quarter profit 762 million U.S. dollars, down 25% QoQ , down 18% from a year earlier. Dell CEO Kevin Rollins said: "The intensity of competition in the market beyond our expectations." Analysts believe that Dell is facing declining performance of the board, shareholder pressure, Dell alliance at this time, AMD, is under pressure to choose.

Steve Felice, president Dell Asia-Pacific in the interview with this reporter, said that Dell's business development is very important, is to hear directly from customer feedback, if the customer needs, must find ways to meet. Current customers in high-end servers on AMD's products are very high demand, this is Dell's high-end servers to use AMD chips.

Dell made the decision quite cautious. Some analysts believe that Dell's sales of AMD products, the need for additional design and construction of additional production lines, may give the company more complexity and higher costs. In accordance with the established practice of Dell, Dell certainly has done the exact calculation of inputs and outputs only after such a major decision to make.

In Greater China, Sun senior director Lin Wenxi view, Dell alliance AMD, AMD's product description has come to harvest. "If Dell to enter the field which shows that the field is mature."

Dawn's server product manager, said Shen Yang, now the dawn of the server using Intel processors and AMD processors, the ratio of about 5:5. Choice of a server, users have the final say.

In China in the server vendors, the wave is yet to cooperate with AMD server manufacturers. When asked whether cooperation with AMD, the wave of the server's public relations officer, said: "does not exclude such a possibility."

AMD really win?

Dell is for AMD, of great significance. Dell is not only one of the world's three major server vendor, or the world's largest PC maker, Dell took over the castle, is a major victory for AMD, but its future long way to go.

Dell announced the alliance at AMD, the Nasdaq Stock Exchange when the regular trading week Friday, AMD shares rose 3.6 U.S. dollars, or 11%, to close at 34.95 U.S. dollars; Intel shares fell 29 cents, down 1.5%, to close at 18.36 U.S. dollars.

In a statement released by AMD, AMD director of global commercial market, said Marty Seyer, senior vice president: "We welcome Dell, and users to join the AMD camp!"

But analysts say high-end server products only a small fraction of Dell's total sales, Stifel Nicolaus analyst Cody A Kerui (Cody Acree) in the research report pointed out that multi-core server market, Dell is lagging far behind the major competitors HP and IBM, ranked third. According to Citigroup analyst Glen Yeung estimates that high-end Dell server sales accounted for all server products revenue of 5%. Dell reported last quarter, server and network products revenue of 13 billion U.S. dollars, accounting for 9% of the company's sales. Yeung said the analyst, can be deduced, Dell only change the CPU of some products provider, on AMD and Intel, the financial impact will be very limited.

Dell's Asia Pacific president acknowledged that most of Dell's server products continue to use Intel chips. Before the transfer for the AMD-based servers Dell servers will account for 10% -20%, AMD side noncommittal.

Dell to adopt AMD processors, greater significance is that the AMD processors into the Dell desktop and notebook computer products possible. Analysis that breaks in the past, AMD model of cooperation with other enterprises is generally from the server to the desktop and notebook PCs, Dell and AMD's cooperation may also be the case.

President of Dell Asia-Pacific response to the question on this very "official": "does not exclude such a possibility. If we cooperate in the PC, will tell the media."

To be launched at the end of the year-end servers based on AMD processors will launch in China, AMD's public relations staff did not give comment. Dao Shi, President Asia Pacific, said Dell, AMD's growth in the Asia Pacific than in the United States faster than the large U.S. market share. AMD in the Asia Pacific customer acceptance is higher than other markets, which Dell introduced in the Asia-Pacific AMD's products are very useful.

In addition to other Dell, AMD is still continuing with the other battle, such as working with the wave of positive engagement. One commented that the industry, AMD negotiations with OEM manufacturers, OEM companies are qualified to say the conditions, but AMD is still not qualified to talk conditions. CCW Research analyst Guo Chang said: "AMD can only win a battle, not a battle."

Intel will change

According to the Associated Press reported that the recent decision for Dell, Intel CEO Paul Otellini said in an internal memo was disappointed. He said: "This is an incredible, extremely disappointing decision."

Significantly, Dell announced a few days before using AMD chips, Intel China has replaced senior management. Former co-general manager of Intel China, Lai Yit Loong will officially leave on June 10 Intel, another co-general manager Jane Angel will be transferred back to U.S. headquarters. Intel vice president and general manager of Asia Pacific Yang regain the helm of Intel China. Some analysts believe that for the Chinese market is more familiar with Yang and return to China shows that China's domestic market, Intel hopes to "check" aggressive AMD.

Analyst who is familiar with Intel, said Intel's general manager before the "foreigners" as limited communication with local enterprises. Although they work very hard, but they are still difficult to integrate into the circle in a short time.

May 16, Yang re-appointed at the beginning, it appeared a Lenovo notebook computer conference, which is considered Yang desire to improve relations with downstream manufacturers of a hint. The two previous co-general manager of Intel ruled that, despite the many efforts, such as GAPP program to support regional brand, but AMD's momentum can not stop. Last year, Intel's other main coalition party also backward with AMD, so Intel had to re-examine the relationship with the OEM manufacturers.

In the past few years, the cooperation with the downstream business, Intel is undoubtedly the absolute master, and Intel used to be good for a deal with the various vendors. It can be said for Intel's strong position, OEM manufacturers do not have much say in public. AMD's rise, with some changes to this situation. To a certain extent, AMD and Intel have become public companies bargaining chips.

Dell and AMD is just the beginning of cooperation, and perhaps not end.
