BET could be the winner for banishing 'not spots'
Kenton Group says that by using Broadband Enabling Technology (BET) it is now possible to provide broadband to parts of the UK that were previously unreachable.
The network access specialist claims that it has doubled signal strength and that BET will enable operators to provide up to 2Mbps links to the 1.5 million UK households which are currently on low speeds.
BET works by amplifying the broadband signal from around 5km to 12km using existing one or two pair copper cables. According to Kenton, this arrangement enables users to receive the same level of service as other households positioned closer to an exchange.
The solution comprises a BET card installed at the telephone exchange, a remote unit in the street cabinet, and a Network Terminating Unit in the premises. Using this system, the originating signals are converted, transmitted, boosted and converted back to ADSL.
"Dawn of the terabit age"
Laser-powered semi-conductors could enable the industry to move from 100Gbps channels to Terabit channels.
Digital optical network company Infinera claims that it has demonstrated a Terabit photonic integrated circuit (PIC) transmitter which integrates ten wavelengths, each operating at 112Gbps for an aggregate data rate of 1.12Tbps.
The company says that the implementation of its Terabit FlexChannels, which are designed to leverage the fibre spectrum to achieve greater spectral density, should enable networks to scale to capacities up to 25Tbps. They are said to use narrow linewidth lasers and dual states of polarisation to achieve a data rate of 112Gbps per channel, and during the demo, Infinera says that error-free transmission was achieved for all ten channels.
The vendor’s 500Gbps PIC is planned to be commercially available in its systems next year. Platforms based on PICs with 1Tbs capacity or greater are planned for future systems.
Old data centre gets the boot at Loughborough
Loughborough University is replacing it 40-year-old data centre and hopes to save over 640 metric tonnes of CO² per annum thanks to cloud networking.
Logicalis will design and build a bespoke private cloud for the university, fully integrated with an off-site, co-operative hosted cloud. This single, scalable architecture is expected to provide unlimited scope for future capacity provisioning.
The agreement also includes a UC and collaboration suite for 3,000 university staff and 1,600 business and community engagement tenants across the campus.
In addition, Logicalis claims that the deployment of a new LAN and WAN will create a secure, robust and highly available IT infrastructure.
Virtualisation will also be implemented across Loughborough’s corporate desktops.
TUI Travel journeys to the cloud
TUI Travel will use managed infrastructure services from Dell Services. The vendor will deploy its ITIL-based best practices and systems as well as cloud-based asset management capabilities to help the travel firm boost cost savings and productivity.
Under the agreement, Dell will help TUI standardise its toolset and infrastructure, specifically for IT services that support its employees. It will also "modernise" the firm's printer fleet.
According to Dell, this will help decrease the total cost of printing, enabling TUI to focus on its core business, and not the day-to-day management of a complex fleet of printers, copiers, faxes, scanners, and multi-function devices.

124 further AET's
Stonesoft recently announced 124 further AET's (Advanced Evasion Techniques) via CERT. Evasions are a way to bypass network intrusion prevention systems (IPS) or any security device that is designed to do network traffic inspection. Stonesoft recently discovered the advanced evasion techniques – a new threat category that existing network security systems are not able to detect.

Your data centre can grow with your business!
Whether your company just doubled its sales or staff, you need to make sure that your data centre can support such growth – not hinder it. All too often, though, businesses feel constrained by the capabilities of their IT infrastructure. Is there enough rack space to handle more servers? Can power capacity accommodate larger IT loads? Today, APC by Schneider ElectricTM eliminates these hurdles with its proven high-performance, scalable, and complete data centre architecture solution: InfraStruxureTM.

Virtual Desktop Infrastructure (VDI).
David Angwin, director of marketing EMEA, Wyse Technology offers this advice:
- Including the desktop is essential. Many of the costs of traditional PC desktop infrastructures are related to deploying, securing, managing and refreshing the PCs themselves. Although it's possible to implement VDI and keep the PC desktops, this will increase, rather than decrease, the total cost of ownership.
- Free up budget to deliver new services. Analysts estimate that up to 70 per cent of IT budgets are spent on maintenance and support. Choosing virtual desktops that require minimum or zero management at the desktop creates savings that can be ploughed back into the business to develop new services. The sums saved are high - one business was able to cancel a £500,000 PC maintenance contract because of desktop virtualisation.
- Think real energy savings. You don't need to be motivated by green issues to use the greater energy efficiency of virtual desktops to make your case. There are substantial savings to be made. For example, since switching to VDI, city bankers Standard Bank say their energy consumption dropped by 312,539 kWH per year, or roughly $50,000 in savings. Large numbers of PCs produce a lot of hot air that has to be cooled, adding to the load on air conditioning systems.
- End user resistance is a myth. Advances in virtualisation at the desktop and server mean end users frequently get a better user experience when their PC is switched from a thin or zero client, even with rich multimedia applications. Instant start-ups and applications that perform fast consistently enable users to get on with their jobs and increase productivity.
- Enable more efficient ways of working. The ability to log into your personal desktop wherever you are within the organisation supports more flexible and collaborative working patterns.
- Efficient offices are better to work in. Moving to a VDI infrastructure breaks the 1:1 link between a user and their desk. This lets office space be used more efficiently and can help to reduce the amount of office space required.
