Top 1% of Mobile Users Consume Half of World's Bandwidth, and Gap Is Growing [06Jan11] - 0 views

  • The world’s congested mobile airwaves are being divided in a lopsided manner, with 1 percent of consumers generating half of all traffic. The top 10 percent of users, meanwhile, are consuming 90 percent of wireless bandwidth, reports Kevin J. O’Brien in The New York Times.

Wireless bandwidth: Are we running out of room? [29Jan12] - 0 views

  • Wireless bandwidth is like land in Manhattan -- it's extremely valuable because they're not making more of it.
  • But we sure are using more of it. The wireless-industry association CTIA reported in October 2011 that the number of wireless devices in the U.S. had, for the first time, exceeded the number of people. And Mobile Future, a coalition of vendors and consumers, estimated in a March 2011 report that by 2014, voice traffic will comprise only 2% of the total wireless traffic in the United States -- a worrisome statistic because, as the report noted, smartphones consume 24 times more data than old-school cell phones, and tablets consume 120 times more data than smartphones. (See Data needs bandwidth, but how much? for details.)
  • The result: Wireless networks are edging near capacity, not just in the United States, but all over the world. Credit Suisse conducted a survey last year that revealed mobile networks in North America were running at 80% of capacity, with 36% of base stations facing capacity constraints. The average globally for base station capacity utilization, the report said, was 65%.

  • The problem is going to get worse before it gets better. With advancements in connected cars, smart grids, machine-to-machine (M2M) communication, and domestic installations such as at-home health monitoring systems, wireless demands will only increase. As with all things mobile, there are no simple answers, if only because potential solutions rely on agreement among a sizable and incompatible array of players -- from spectrum owners (both telcos and broadcasters) and regulators to government agencies and, of course, consumers demanding the latest in cool devices and applications.

IBM's Andy Piper: Negotiating the Internet of Things - 0 views

  • He is officially called the "Messaging Community Lead" for IBM's WebSphere message queue (MQ) architecture, which is a title that grants some modicum of honor without claiming too much authority. Andy Piper has become IBM's point man for the concept of a planet enmeshed in billions, perhaps trillions, of signal-sending, communicating devices. The case may be made that anything that can be "on" could be made to send a signal on a network - perhaps something as simple as "on" itself, periodically. The possibilities for a world where the operating status of any electronic device may be measured from any point on the globe, are astounding.
  • Two weeks ago, IBM and its development partner Eurotech formally submitted Message Queue Telemetry Transport protocol to the Eclipse Foundation open source group. It's being called "the" Internet of Things (IoT) protocol, but in fairness it's only one candidate. It would serve as the communications mechanism for devices whose size may scale down to the very small level, with negligible power and transmission radius of only a few feet.
  • One example application already in the field, Piper told RWW, is in pacemakers. Tiny transmitters inside pacemakers communicate using MQTT with message queue brokers at their patients' bedsides. Those brokers then communicate with upstream servers using more conventional, sophisticated protocols such as WebSphere MQ.

  • "Look, this is engineered for a constrained environment," Piper emphasized. "But because of that, [these devices] are actually extremely efficient at doing things like conserving battery, and using very low bandwidth. So [MQTT] is actually a fairly sensible protocol for both the machine-to-machine (M2M) space that we're addressing with the Eclipse announcement, and also the mobile explosion as well. All these devices need to be connected."
  • "It's not as such about replacing the Web; it's about enabling devices to talk to the Web," says Piper. "And these devices are unlikely to have user interfaces; they're really about just collecting data."
  • IBM's model (like all IBM models through history) is layered and given a mnemonic. There are three classes of devices: intelligence, interconnect, and instrumentation. Unlike Microsoft's model, which argues that intelligence can be driven completely to the edge at the device level, IBM maintains intelligence at the core, maybe even in the cloud. Instrumentation, on the other hand, doesn't need to be all that intelligent. In fact, it can be essentially autonomic. But it can still communicate, and MQTT would be its protocol.
  • "When you look at the wire trace of an HTTP packet, you end up with a lot of stuff in the headers which you don't see as a user," he tells RWW. "HTTP was designed for getting documents to a user interface. And it's been kind of bent and twisted into being used for inter-application and server-side communication, and that's fine when you have the bandwidth. But if you just want to send, 'The temperature is ___,' and then send 61.7, 60,7, 61.7, every five seconds, you really don't want to be doing a full HTTP post to send that information to an endpoint. So [MQTT] is asynchronous push; it's not request/response, which is what HTTP is."
  • Current networks of devices, such as Cisco routers, utilize small packets of health and status data that some literally call "weather reports." They're sent at specific intervals, and when they don't arrive on time, servers conclude something may be wrong. Such "weather reports" have been said to constitute a majority of the actual messages sent between routers and other devices at the lower levels of the Internet.

BBC News - Secret net Tor asks users to sign up to cloud services - 0 views

  • The Tor developers are calling on people to sign up to the service in order to run a bridge - a vital point of the secret network through which communications are routed. "By setting up a bridge, you donate bandwidth to the Tor network and help improve the safety and speed at which users can access the internet," the Tor project developers said in a blog.
  • "Setting up a Tor bridge on Amazon EC2 is simple and will only take you a couple of minutes," it promised.
  • Users wishing to take part in the bridging project, need to be subscribed to the Amazon service.

  • It normally costs $30 (£19) a month. However, Amazon is currently offering a year's worth of free storage as part of a promotion, which Tor developers believe their users will qualify for.
  • Amachai Shulman, chief technology officer of data security firm Imperva believes that cloud services could have a big impact on Tor. "It creates more places and better places to hide," he said.
  • Tor is also used by people wanting to share images of child abuse. Hacktivist group Anonymous recently launched Operation Darknet which targets such abuse groups operating via the network. "There is an ugly face to Tor," said Mr Shulman. "Studies suggest that most of the bandwidth is taken by pirated content."
  • Imperva research estimates that there are currently "a few thousand" exit nodes on Tor - the points at which communications reveal themselves on the wider internet.

The data center gets its first 100 Gbps optical chip - Tech News and Analysis [08Nov11] - 0 views

  • Luxtera, which makes a optics chips that has characteristics of a standard silicon chip, has developed a hybrid chip for the data center market that can achieve speeds of more than 100 gigabits per second. Those are the same speeds that telecommunications firms are enabling via long-haul cables to handle the massive demand for bandwidth worldwide, but in this case are designed to handle the next wave of big data and networking-intensive applications inside webscale and cloud data centers.
  • Luxtera was founded in 2001 and builds chips that allow messages to be sent at the speed of light, but instead of using specialty materials that optics chipmakers such as Infinera use, Luxtera uses traditional silicon chips made using the CMOS process. This cuts down on the cost of the chips and makes it possible to use them for high-volume jobs, such as switching in the data center.
  • Luxtera’s single chip opto-electronic transceiver includes four fully integrated 28Gbps transmit and receive channels powered from a single laser for an aggregate unencoded data rate of up to 112Gbps. The device is targeted for 100Gbps Ethernet, OTN and InfiniBand applications as well as emerging OIF (Optical Internetworking Forum) Short Reach (SR) and Very Short Reach (VSR) electrical interconnect to host systems. … The optical transceivers can be socketed directly onto the customers’ switch or server boards for both backplane and rack mount connectivity.

  • The ascendancy of fiber isn’t just happening in our home broadband and long-haul networks, but also must occur inside the data center and even on the chips themselves as we demand more from our computers and networks. Luxtera’s chip helps usher in the age of light inside the data center in a way that doesn’t require the replacement of all the existing gear. Luxtera will sample the chips this year with the chips supporting both Ethernet and Infiniband applications.

How the Rise of Google's Chromebook Is Like the Rise of Multicellular Life - Technology... - 0 views

  • For Google, the increasingly available broadband / fiber-optic / wireless network is oxygen. Smart phones are proof enough that thin clients can succeed in this early atmosphere, but it's not yet rich enough for them to become the technological equivalent of anything more complex than jellyfish. Which, not incidentally, ruled the seas of the early earth.
  • Denser, higher-bandwidth communications networks(more wi-fi hotspots; more numerous, smaller and faster cell towers) are the direct equivalent of a denser atmosphere. Google's Chromebook not only has the ability to take advantage of this ever-improving network, it also has the power to drive it, just as smartphone adoption has already forced cell carriers to invest heavily in their existing networks.

New research breakthrough will boost optical networks [21Jun11] - 0 views

  • A research team at the Chalmers University of Technology in Sweden has come up with a new optical amplifier that can help boost the efficiency of backhaul optical networks, a move that could have a big impact on the overall economics of bandwidth.
  • Chalmers’ new breakthrough is more efficient and allows optical signals to be sent over longer distances 4,000 kilometers as opposed to 1,000 kilometers – which in turn would make the cost of building and operating the networks cheaper.
  • “The entire optical telecom industry is our market. But the technology is generic, and scalable to other wavelengths like visible or infrared light, which makes it attractive in areas such as measurements, spectroscopy, laser radar technology and any applications where detection of very weak levels of light is essential”, says Peter Andrekson.

Global optical networking market to be worth US$20 billion by 2016 [22Jun11] - 0 views

  • The global optical networking (ON) market will reach revenues of $20 billion by 2016, as the sector pulls itself out of the economic downturn, predicts Ovum in a new forecast. However, the independent telecoms analyst warns that although the global market will grow at a compound annual growth rate (CAGR) of 6% from 2010 to 2016, not all of the regions will see strong growth. Ian Redpath, Ovum analyst and author of the forecast, said that "increasing bandwidth from residential broadband networks, mobile networks, and enterprises is the key driver of the growth. Carriers are investing in access networks and mobile long term evolution (LTE) rollouts are beginning to gain momentum. The ON market is also reaching a watershed moment in terms of technology. Networks based on 40G and 100G wavelengths are now poised for mass-market deployment.

Global optical networking market on the up [22Jun11] - 0 views

  • The global optical networking market is estimated to reach revenues of $20 billion in 2016, according to analyst firm Ovum. The global market is forecast to grow at 6% CAGR between 2010 and 2016, driven by investment from carriers in 40G and 100G networks. This level of growth, however, will vary according to region, with the North American market, for instance, estimated to grow by 12% this year while the Asia-Pacific market is predicted to contract by a further 3.2% in 2011. “Increasing bandwidth from residential broadband networks, mobile networks, and enterprises is the key driver of the growth. Carriers are investing in access networks and mobile long-term evolution (LTE) roll-outs are beginning to gain momentum,” said Ovum analyst Ian Redpath. “The optical networking market is also reaching a watershed moment in terms of technology. Networks based on 40G and 100G wavelengths are now poised for mass-market deployment.”

The Internet in Africa - still an alien concept - 0 views

  • With the excitement surrounding the arrival of undersea cables in Sub-Saharan Africa and the prospects of the smartphone revolution in bringing mobile connectivity to most parts of the continent, it is easy to forget for instance that the continent still has 1 domain per 10,000 users.
  • In education, there are the vast prospects that e-learning provides for students, but doing this in a way that scales is difficult in Africa’s low bandwidth environment. There are also prospects in various sectors ranging from agriculture to finance each with its own unique set of challenges.
  • Amidst this backdrop, the obvious respite for bridging the access gap appears to be through smart phones. However, majority of Africans can only afford the cheapest of phones which are typically low end phones. To truly expand access, smart phone prices will need to crash drastically and rural connectivity would need to expand dramatically. Save for these two actions, revolutionizing the continent via the Internet will continue to remain a pipe dream.

  • Blackberry. Though the brand has faced declining popularity in countries like the United States, it is facing rising popularity in Nigeria and South Africa where its youths voted it as the country’s leading smartphone brand.
  • However, venturing into the continent to make the next multi-million dollar web company is not for the faint hearted. How do you market your products online in a continent where the vast majority of people have never experienced the web? There are ways around this such as through SMS based services but even this is challenging given the low literacy rates in many African countries.
