IPv4 addresses have been used up
The current crop of Internet addresses could start to disappear this week if a regional Internet registry makes one more request for two blocks of addresses.
APNIC (Asia Pacific Network Information Centre) is eligible to request two large blocks of IPv4 (Internet Protocol, Version 4) addresses, because users have been snapping up its existing stock quickly enough, according to Leo Vegoda, manager of number resources at the Internet Assigned Numbers Authority. Because there are only seven of these large blocks left, that allocation to APNIC would activate a policy for the IANA to hand out the last five blocks to the five regional registries, Vegoda said.
Experts have been warning ISPs (Internet service providers) and enterprises for years that IPv4 addresses are destined to run out soon. Various technical fixes have staved off that day, but the assignment of those final blocks would leave the ultimate supply of those addresses tapped out. This would mark a milestone on the path to an Internet based totally on the latest protocol, IPv6.
IPv6 has a much larger address space, which allows for an almost limitless number of unique addresses. The IANA allocates IPv6 addresses in a similar way to IPv4, except in much larger "/12" blocks, Vegoda said.
The expanded address space is expected to be most critical to users in quickly developing countries such as China and India, as well as for the many new mobile devices being used for Internet access. The transition to IPv6 will be gradual, but even an enterprise that has enough IPv4 addresses should start supporting IPv6 in order to reach the new end points that won't be able to get IPv4 addresses, Vegoda said. Otherwise, they eventually will need to go through devices on ISP networks that translate between the two protocols. Those could introduce delays, and possibly communication problems if they were incompatible with certain protocols, he said.
Google, Facebook, Cisco Systems, Verizon Business and other major vendors and service providers will take part in World IPv6 Day in June, a global test of the new protocol organized by the Internet Society. For 24 hours, the participating companies will run their public websites on both IPv4 and IPv6.
由「IPv4」向「IPv6」轉型是個巨大工程，除了所有終端用戶，都必須更換終端設備接入網際網路的路由器或調製解調器之外，所有網站和網際網路服務商，也都必須全面改造，提供適用於「IPv6」協議的終端設備入網「接口」。很多網站和網際網路服務商認為，這種改造太費「周折」，因而一直堅持使用基於「IPv4」協議的網絡接入標準。

2011 Enterprise Trends of ICT
Independent technology analyst Ovum, has named its top ten trends for the coming year, which also include mobility, data management and data centre transformation.
Business analytics, collaboration, IT financial management and context-aware computing also make the list and author Mark Blowers believes the trends provide both opportunities and challenges.
“These are the key trends that will define the IT landscape for CIOs in 2011. If CIOs do not have a strategy for how they intend to take advantage of the opportunities they provide, and deal with the challenges they bring, then they should form one as an urgent priority.”
Security
Security continues to be high on the IT agenda as the number of threats to businesses increases rapidly. “New technologies such as mobility, social media and cloud computing present new opportunities, but also vulnerabilities,” believes Blowers. “No amount of investment in technology alone can prevent attacks from criminal gangs and cyber espionage. In 2011, CIOs should adopt an approach that brings together technology, policy and people. The wider picture for corporate protection must also include risk, compliance and regulatory issues.”
Data management
Data management will be a key area due to the sheer volumes now passing through enterprises. “The management of data will come to a head for CIOs in 2011, who will realise that it is an issue that can no longer be ignored,” predicts Blowers. “The issue of hardware capacity and the drain on resources will see data management make it on to the investment agenda for IT departments in 2011. We believe they need to address both master data management and storage management to deal with the issue effectively.”
Business analytics
“Business analytics will remain an important tool for organisations that want to differentiate themselves from the competition in 2011,” says Blowers. “The technologies’ ability to improve decision-making, identify new business opportunities, maximise cost savings and detect inefficiencies is driving its importance for organisations.”
Mobility
In IT management, the mobility challenge in 2011 will be to embrace the new technology while developing a strategy that maintains a balance between user preference and productivity and corporate security and compliance. “As well as challenges, there is a big opportunity for enterprises to revolutionise business processes and customer interaction using new mobile apps,” says Blowers.
Data centre transformation
The role of the data centre is witnessing a dramatic shift as the cloud computing era heralds a new dawn in the delivery of IT services in 2011. “The impact of this shift will be to transform current organisational thinking about the value of building and operating large complex data centres,” predicts Blowers.
Cloud services
Cloud computing will continue to grow steadily in 2011. Ovum believes that it is no longer a question of whether or not enterprises will use cloud computing, they already are. However, it is still early days for both providers and CIOs, who will grapple to take advantage in 2011.
Collaboration
To cater for changes in work practices, an integrated approach to collaboration is needed which includes social networking and video conferencing. “In 2011, enterprises will move from a traditional hierarchy based on command and control, to looser structures using collaboration and teamwork,” says Blowers.
Sustainability
New opportunities will continue to emerge in 2011 which allow organisations to work in a more environmentally-friendly way. “IT management with the use of new technologies will take more of a leading role in helping the organisation to meet sustainability expectations and save money,” says Blowers.
IT financial management
The CIO should talk the language of business and put in place better IT financial management in 2011. “Changes are needed to improve the IT department’s relevance to an organisation and prove the value of investment to the business. Better financial management can help with this.”
Context-aware computing
In 2011, CIOs should be looking to instrumentation, metering and wireless technologies to play a significant role in providing the context which can lead to automated business processes and increased productivity. “It is also important to fully understand the impact increased contextual data will have on the IT environment and applications, as well as back-end infrastructure.”

Supercomputer to go sugar cube-sized in few years
.
LONDON: IBM scientists have said that a pioneering research effort could shrink the world's most powerful supercomputer processors to the size of a sugar cube.
The approach will see many computer processors stacked on top of one another, cooling them with water flowing between each one. The plan is to reduce computers' energy use, rather than just to shrink them.
Dr Bruno Michel said future computer costs would hinge on green credentials rather than speed.
Michel and his colleagues have already built a prototype to demonstrate the water-cooling principle. Called Aquasar, it occupies a rack larger than a refrigerator.
IBM estimates that Aquasar is almost 50 pc more energy-efficient than the world's leading supercomputers.
"In the past, computers were dominated by hardware costs - 50 years ago you could hold one transistor and it cost a dollar, or a franc," the BBC quoted Michel as saying at IBM's Zurich labs.
Now when the sums are done, he said, the cost of a transistor works out to 1/100th of the price of printing a single letter on a page. The overwhelming cause of those energy costs is in cooling, because computing power generates heat as a side product.
The Aquasar prototype clocked up nearly half again as much, at 1.1 billion operations. Now the task is to shrink it.
"We currently have built this Aquasar system that's one rack full of processors. We plan that 10 to 15 years from now, we can collapse such a system in to one sugar cube - we're going to have a supercomputer in a sugar cube."

Mark Stromberg, principal research analyst at Gartner, said that the approach was a promising one.
But he said that tackling the finer details of cooling - to remove heat from just the right parts of the chip stacks - would take significant effort.
