Seamless MPLS Architecture

Seamless MPLS architecture can be used to create very large  scale MPLS network, reduces operational touch points for service creation, reduces overall complexity and enable flexible service creation points in the Service Provider networks. Seamless mpls architecture best suited for the very large scale service provider networks which has 10s or 100s of thousands access nodes, very… Read More »

Orientation

Quick — can you OODA? Last week we talked about the general idea behind the OODA loop; this week we’ll cover the last three steps and wrap up.

Orient is the second step: once you’ve made a set of observations, you need to decide what it is you’re actually observing. To help this make sense, let’s take a look at a simple optical illusion — you might have seen it before.

perfectsquares

Do the blue squares look square, or… ?? If you’re like most people, the squares don’t look square at all — but they are. Remember the blue or gold dress? In both of these situations, we face the same sort of problem: our ability to perceive is often influenced by the context.

This doesn’t, as some people try to say, mean that our senses are all just a jumbled up mess, and the entire world is disconnected from our brains — you must be careful in life not to make the hard or odd case the rule by which all other cases are measured. Every measurement system has its limits; that doesn’t mean the measurement is useless or generally untrustworthy.

So what we must do, as network engineers, is to Continue reading

Nokia, DoCoMo test high-frequency mobile with an eye on 5G

Nokia Networks and Japanese carrier NTT DoCoMo are testing networks using extremely high frequencies that may someday deliver multi-gigabit speed to mobile devices.The companies’ technology trial is using 70GHz radios that today are about the size of a carry-on suitcase. Eventually, the technology will shrink down to about 5 millimeters across to fit in a mobile device.So-called millimeter-wave radios can pack a lot of data into a narrow beam, and the frequencies they’re designed to use aren’t in high demand these days. That’s why Nokia and other vendors see this technology as a key part of the future 5G mobile standard coming in 2020.To read this article in full or to leave a comment, please click here

DoCoMo app shares SIM credentials with offline devices

Japanese mobile carrier NTT DoCoMo has developed an app that can wirelessly send authentication credentials to devices that are not connected to the Internet, allowing more hardware to get online or query the cloud.Potential applications of the technology include the ability to share mobile SIM user credentials such as phone numbers among multiple devices without the need to physically transfer a SIM card. It could also be used for giving online access to IoT (Internet of Things) hardware.Based on prototype hardware announced last year, the Portable SIM App for Android can transfer data with a wave of a hand. The carrier is exhibiting the app at Mobile World Congress this week in Barcelona.To read this article in full or to leave a comment, please click here

Chip makers NXP and Freescale plan merger, focusing on car chips and wearables

Chip makers NXP Semiconductors Freescale Semiconductor are to merge, creating a US$40 billion company that, they say, leads the market in automotive chips and general-purpose microcontrollers.The combined entity will have revenue of over $10 billion, much of it from microcontrollers and chips for cars, the companies said. As mobile phone and automobile manufacturers join forces to bring more intelligence to vehicles, and as the market for wearables and other small connected devices takes off, these markets are likely to see strong growth.To read this article in full or to leave a comment, please click here

Qualcomm puts silicon brain in flagship Snapdragon 820 chip

Qualcomm wants to help future mobile devices learn about their users, by putting cognitive computing capabilities into its next mobile microprocessor, the Snapdragon 820. The chip will provide mobile devices with some brain-like learning capabilities by incorporating features from Qualcomm’s Zeroth platform. Mobile devices built with the Snapdragon 820 will be able to learn about users over time, picking up human activity patterns and anticipating actions. Putting the machine learning features on the chip, rather than in the cloud, will make mobile devices more personal and more useful than they are today, said Derek Aberle, president of Qualcomm, in a news conference at Mobile World Congress in Barcelona on Monday.To read this article in full or to leave a comment, please click here

Will network disaggregation play in the enterprise?

Disaggregation seems to be all the rage in networking these days.HP is the latest to decouple merchant silicon-based hardware from operating system software, following Dell and Juniper. The strategy is to attract web-scale companies like Google, Facebook and Amazon who need the flexibility, choice, rapid deployment/decommissioning and cost efficiency of commodity “white box” switches capable of running a variety of software packages.To read this article in full or to leave a comment, please click here

Sony’s Xperia Z4 Tablet is light and has two good cameras

By putting its flagship tablet on a diet, improving cameras and battery life, Sony wants to bring back some luster to the tablet market. Unlike HTC and Samsung Electronics, Sony isn’t launching a high-end smartphone at Mobile World Congress, but is hoping to make up for that with a new flagship tablet, the Xperia Z4 Tablet. It has a 10.1-inch, 1600 x 2560 pixel screen and is powered by Qualcomm’s octa-core Snapdragon 810 processor. The Wi-Fi version weighs 389 grams while the LTE version is slightly heavier at 393 grams, and both are 6.1 millimeters thick.+ See our full coverage of MWC 2015 +To read this article in full or to leave a comment, please click here

For a speed boost, Alcatel-Lucent says use both cell and Wi-Fi

If you have both cellular and Wi-Fi, why not use both? At Mobile World Congress, Alcatel-Lucent is demonstrating a way to do that as part of the same network. Cellular and Wi-Fi are rubbing shoulders more than ever, even if that can cause friction in some cases. It’s all part of the quest for more mobile capacity for applications like video streaming. Several ways of using them together are on show at MWC. Like other vendors, Alcatel is pursuing LTE-U, which lets an LTE network use the unlicensed spectrum that powers Wi-Fi. But the French-American company is also demonstrating a technique it calls Wi-Fi boost, where users can upload data to the Internet over cellular and download it using Wi-Fi. The company plans trials of Wi-Fi boost in the second quarter of this year and will start selling it in the second half.To read this article in full or to leave a comment, please click here

Sony’s Xperia M4 Aqua is full-featured, waterproof and affordable

The mid-range of the smartphone market is getting hyper-competitive, but Sony is betting the waterproof Xperia M4 Aqua will help it make a mark.Well-equipped smartphones that cost US$300 or less is one of the big trends at this year’s Mobile World Congress, and Sony wants in on the action.Last week it launched the Xperia E4g and on Monday it announced the Xperia M4 Aqua.The smartphone will cost about €300 (US$335) when it goes on sale during the second quarter in 80 countries. It has a 5-inch, 720 x 1280 pixel screen and is powered by Qualcomm’s Snapdragon 615, an octa-core processor with integrated support for LTE. The processor is a step below the Qualcomm’s Snapdragon 800 family, which is used to power high-end smartphones.To read this article in full or to leave a comment, please click here
