HTTP2 Procotol Nears Completion

Comments Off on HTTP2 Procotol Nears Completion

When it comes to amping up traffic over the Internet, sometimes too much of a good thing may not be such a good thing at all.

The Internet Engineering Task Force is putting the final touches on HTTP/2, the second version of the Hypertext Transport Protocol (HTTP). The working group has issued a last call draft, urging interested parties to voice concerns before it becomes a full Internet specification.

Not everyone is completely satisfied with the protocol however.

“There is a lot of good in this proposed standard, but I have some deep reservations about some bad and ugly aspects of the protocol,” wrote Greg Wilkins, lead developer of the open source Jetty server software, noting his concerns in a blog item posted Monday.

Others, however, praise HTTP/2 and say it is long overdue.

“A lot of our users are experimenting with the protocol,” said Owen Garrett, head of products for server software provider NGINX. “The feedback is that generally, they have seen big performance benefits.”

First created by Web originator Tim Berners-Lee and associates, HTTP quite literally powers today’s Web, providing the language for a browser to request a Web page from a server.

Version 2.0 of HTTP, based largely on the SPDY protocol developed by Google, promises to be a better fit for how people use the Web.

“The challenge with HTTP is that it is a fairly simple protocol, and it can be quite laborious to download all the resources required to render a Web page. SPDY addresses this issue,” Garrett said.

While the first generation of Web sites were largely simple and relatively small, static documents, the Web today is used as a platform for delivering applications and bandwidth intensive real-time multimedia content.

HTTP/2 speeds basic HTTP in a number of ways. HTTP/2 allows servers to send all the different elements of a requested Web page at once, eliminating the serial sets of messages that have to be sent back and forth under plain HTTP.

HTTP/2 also allows the server and the browser to compress HTTP, which cuts the amount of data that needs to be communicated between the two.

As a result, HTTP/2 “is really useful for organization with sophisticated Web sites, particularly when its users are distributed globally or using slower networks — mobile users for instance,” Garrett said.

Comments Off on Salesforce Goes Healthcare

Salesforce Inc, one of the first cloud-computing companies, is turning its focus towards healthcare with new software and services aimed at the largest hospitals.

Salesforce has announced a strategic alliance with Amsterdam-based medical technology company Philips, which it envisions as the first of many partnerships. These companies will announce two new medical applications later in the summer, called Philips eCareCoordinator and Philips eCare Companion.

The software is designed to improve health and cut costs. The apps are intended to be used by physicians to monitor chronically ill patients between doctor visits.

Salesforce said the goal is to make it easier for hospitals to collect and analyze data from medical devices, which patients with chronic conditions often use at home.

“In the United States, care providers are facing increasing demands and decreasing reimbursement,” said Michael Peachey, a senior director of solutions and product marketing at Salesforce.

“We want to improve efficiency for physicians by transmitting patient data in real time.”

Peachey said the Salesforce software meets security and privacy rules under the Health Insurance Portability and Accountability Act, known as HIPAA.

In the short term, Peachey said Salesforce intends to develop additional apps with other partners to help doctors and nurses monitor patients from the comfort of their homes.

“It’s an open platform,” he said.

Cheaper Windows Phones Forthcoming

Comments Off on Cheaper Windows Phones Forthcoming

Lower priced smartphones running Microsoft’s Windows Phone operating system are on the way, according to Microsoft.

Speaking at the Computex trade show in Taipei, Microsoft’s Nick Parker, who handles the company’s partnerships with device makers, said the new handsets could be out by the end of the year.

Compared to current models, which are in the “fours, fives and sixes,” he said referring to prices between $400 and $699, the new phones would have price points in the “ones, twos and threes.”

Asked to clarify if he was referring to end-market prices without carrier subsidies, Parker said he was.

He didn’t identify the manufacturers that would be bringing the phones to market, but there’s a good chance they are among nine companies Microsoft signed up to its Windows Phone development program earlier this year.

In addition to existing partners Nokia, Samsung, HTC and Huawei, Microsoft added Foxconn, Gionee, Lava (Xolo), Lenovo, LG, Longcheer, JSR, Karbonn and ZTE.

Some of the new partners have significant market share in developing countries where phones generally have lower prices than in developed markets.

Microsoft launched the latest version of its Windows Phone operating system, Windows Phone 8, in late 2012 to critical praise. The operating system was slow to catch on with consumers though, perhaps due to the absence of several popular apps on the platform, but has been slowly increasing its market share.

Windows Phone had a 3 percent share of the smartphone market in the fourth quarter of 2013, up from 2.6 percent in the last three months of 2012, according to IDC. In contrast, Google’s Android dominated the smartphone market at the end of 2013 with a 78.1 percent share. Apple’s iOS was in second place at 17.6 percent.

IDC forecasts Windows Phone will continue to increase its market share to hit 7 percent in 2018.

Is China Hurting U.S. Vendors?

Comments Off on Is China Hurting U.S. Vendors?

Shipments of servers from Chinese vendors grew at a rapid pace while the top server vendors in the U.S. declined during the first quarter of this year.

Worldwide server shipments were 2.3 million units during the first quarter, growing by just 1.4 percent compared to the same quarter last year, according to Gartner.

Growth was driven by Chinese server vendors Huawei and Inspur Electronics, which were ranked fourth and fifth, respectively, behind the declining Hewlett-Packard, Dell and IBM.

Huawei has been in the top five for server shipments for more than a year, but Inspur Electronics is a new entrant. Inspur builds blade servers, rack servers and supercomputers, and is best known for being involved in the construction of China’s Tianhe-2, which is currently the world’s fastest supercomputer, according to Top500.org.

Chinese servers partly benefitted from the 18 percent shipment growth in the Asia-Pacific region, while shipments in other regions declined, Gartner said in a statement.

Server buying trends have changed in recent years. Companies like Facebook, Google and Amazon, which buy servers by the thousands, are bypassing established server makers and purchasing hardware directly from manufacturers like Quanta and Inventec. That trend in part led to the establishment of the Open Compute Project, a Facebook-led organization that provides server reference designs so companies can design data-center hardware in-house.

Similarly, Chinese cloud providers are building mega data centers and buying servers from local vendors instead of going to the big name brands, said Patrick Moorhead, analyst with Moor Insights and Strategy.

The trend of buying locally is partly due to the security tension between the U.S. and China, but servers from Chinese companies are also cheaper, Moorhead said.

The enterprise infrastructure is also being built out in China, resulting in a big demand for servers. There is also a growing demand for servers from little-known vendors based in Asia — also known as “white box” vendors — in other regions, Moorhead said.

Cisco To Launch Smart City

Comments Off on Cisco To Launch Smart City

Officials from networking giant Cisco Systems and Kansas City, Mo., have signed a letter of intent to build out a new network for smart city services.

Elements of the project call for designing mobile apps for citizen access, digital interactive kiosks, smart street lights and video surveillance in an area called the city’s innovation district.

The project is designed to complement the city’s build out of a two-mile downtown streetcar path, Cisco said in a statement.

Kansas City, Mo. and its neighbor, Kansas City, Kans., are already getting plenty of outside attention from tech giant Google, which picked the area for its first deployment of Google Fiber, an initiative to install fiber optic cable there and in other cities.

Google won’t say how many households are connected to Google Fiber in the area, but it has already installed 6,000 miles of fiber optic cable. Meanwhile, cable provider Time Warner has provisioned 11,000 Wi-Fi hotspots for its Internet customers to use from mobile devices in various Kansas City area locales, including the popular eight-block restaurant and bar district on the edge of downtown called the Power & Light District.

While some citizen groups have been concerned that Google Fiber isn’t reaching enough low-income families in the area with gigabit fiber, there’s a general recognition by city officials that people of all income levels use smartphones and other wireless devices fairly widely. That can only help the Cisco initiative with Kansas City for wireless services.

Kansas City, Mo. Mayor Sly James said the initiative with Cisco promises to connect city services and information with visitors and residents “like never before.”

Third-party app developers will also have an opportunity to build unique and innovative apps for public use.

Cisco will use its Smart+Connected Communities reference architectures to evaluate the initiative and will work with the city and a business consultancy called Think Big Partners to manage a “living lab” incubator for the tech startup community.

Wim Elfrink, Cisco’s executive vice president of industry solutions, credited city leaders with leading the “charge on innovation in the Midwest.”

Virtru Goes Office 365

Comments Off on Virtru Goes Office 365

Virtru has added Microsoft’s Office 365 and Outlook Desktop services to its growing list of compatible email platforms available on its encryption product.

The company, headquartered in Washington, D.C. and launched in January, is targeting people using major email providers who want stronger privacy controls for more secure communication.

The service is designed to be easy to use for end users who may not have the technical gumption to set up PGP (Pretty Good Privacy), a standard for signing and encrypting content.

Virtru is compatible with most major webmail providers, including Google’s Gmail, Yahoo’s Mail and Microsoft’s Outlook webmail, which replaced Hotmail.

Emails sent using Virtru through those services would look like gibberish, providing a greater degree of privacy. Law enforcement or other entities would not be able to read the content unless they could obtain the key.

Virtru uses a browser extension to encrypt email on a person’s computer or mobile device. The content is decrypted after recipients receive a key, which is distributed by Virtru’s centralized key management server.

Although Virtru handles key management, the company is working on a product that would allow that task to be managed on-site for users, as some administrators would be uncomfortable with another entity managing their keys.

Virtru has said it put aside funds to contest government orders such as a National Security Letter or law enforcement request that are not based on a standard of probable cause.

IBM To Become Cloud Broker

Comments Off on IBM To Become Cloud Broker

IBM is in the throes of developing software that will allow organizations to use multiple cloud storage services interchangeably, reducing dependence on any single cloud vendor and ensuring that data remains available even during service outages.

Although the software, called InterCloud Storage (ICStore), is still in development, IBM is inviting its customers to test it. Over time, the company will fold the software into its enterprise storage portfolio, where it can back up data to the cloud. The current test iteration requires an IBM Storewize storage system to operate.

ICStore was developed in response to customer inquiries, said Thomas Weigold, who leads the IBM storage systems research team in IBM’s Zurich, Switzerland, research facility, where the software was created. Customers are interested in cloud storage services but are worried about trusting data with third party providers, both in terms of security and the reliability of the service, he said.

The software provides a single interface that administrators can use to spread data across multiple cloud vendors. Administrators can specify which cloud providers to use through a point-and-click interface. Both file and block storage is supported, though not object storage. The software contains mechanisms for encrypting data so that it remains secure as it crosses the network and resides on the external storage services.

A number of software vendors offer similar cloud storage broker capabilities, all in various stages of completion, notably Red Hat’s DeltaCloud and Hewlett Packard’s Public Cloud.

ICStore is more “flexible,” than other approaches, said Alessandro Sorniotti, an IBM security and cloud system researcher who also worked on the project. “We give customers the ability to select what goes where, depending on the sensitivity and relevance of data,” he said. Customers can store one copy of their data on one provider and a backup copy on another provider.

ICStore supports a number of cloud storage providers, including IBM’s SoftLayer, Amazon S3 (Simple Storage Service), Rackspace, Microsoft Windows Azure and private instances of the OpenStack Swift storage service. More storage providers will be added as the software goes into production mode.

“Say, you are using SoftLayer and Amazon, and if Amazon suffers an outage, then the backup cloud provider kicks in and allows you to retrieve data,” from SoftLayer, Sorniotti said.

ICStore will also allow multiple copies of the software to work together within an enterprise, using a set of IBM patent-pending algorithms developed for data sharing. This ensures that the organization will not run into any upper limits on how much data can be stored.

IBM has about 1,400 patents that relate to cloud computing, according to the company.

Is The US & UK Lacking In Broadband?

Comments Off on Is The US & UK Lacking In Broadband?

The US and UK are stragglers when it comes to consumer broadband download speeds and appear far down in table rankings.

This puts the countries, swaggering authoritarian surveillance monsters that they are, rather low down on the satisfaction scale.

The ranking produced by Ookla is based on results from Speedtest servers, and is called the Net Index.

“Based on millions of recent test results from Speedtest.net, this index compares and ranks consumer download speeds around the globe,” is the explanation.

“The value is the rolling mean throughput in Mbps over the past 30 days where the mean distance between the client and the server is less than 300 miles.”

Hong Kong takes pole position and it is credited as having download speeds in the area of 71.03 Mbps. There is a big drop of around 20 Mbps down to Singapore in second place with 52.85 Mbps and third is Romania, where speeds are 50.82 Mbps.

You have to look a long way down the list before arriving at the UK, which is in 25th place. Here, or there depending on where you live, consumers get a rather meagre sounding 23.55 Mbps.

The United States weighs in at 31st place and has download speeds of 20.77 Mbps. This puts it below the UK, Germany, Estonia, Hungary, Greece and 25 others.

Closer to home the European Commission has published its report on Broadband Coverage in Europe (2012) and reveals progress on broadband coverage targets. It found that while broadband has improved, it could be faster.

Twitter Tightens Security

Comments Off on Twitter Tightens Security

Twitter Inc said it has put in place a security technology that makes it harder to spy on its users and called on other Internet firms to do the same, as Web providers look to thwart spying by government intelligence agencies.

The online messaging service, which began scrambling communications in 2011 using traditional HTTPS encryption, said on Friday it has added an advanced layer of protection for HTTPS known as “forward secrecy.”

“A year and a half ago, Twitter was first served completely over HTTPS,” the company said in a blog posting. “Since then, it has become clearer and clearer how important that step was to protecting our users’ privacy.”

Twitter’s move is the latest response from U.S. Internet firms following disclosures by former spy agency contractor Edward Snowden about widespread, classified U.S. government surveillance programs.

Facebook Inc, Google Inc, Microsoft Corp and Yahoo Inc have publicly complained that the government does not let them disclose data collection efforts. Some have adopted new privacy technologies to better secure user data.

Forward secrecy prevents attackers from exploiting one potential weakness in HTTPS, which is that large quantities of data can be unscrambled if spies are able to steal a single private “key” that is then used to encrypt all the data, said Dan Kaminsky, a well-known Internet security expert.

The more advanced technique repeatedly creates individual keys as new communications sessions are opened, making it impossible to use a master key to decrypt them, Kaminsky said.

“It is a good thing to do,” he said. “I’m glad this is the direction the industry is taking.”

Africa To Lead Global Bandwidth Demand

Comments Off on Africa To Lead Global Bandwidth Demand

Africa’s demand for Internet access to the rest of the world will grow by an average of 51 percent every year until 2019, ahead of all other regions, according to a forecast by research company Telegeography.

Rapid economic growth and wider Internet use will drive the increase in demand, which will be met mostly by turning on unused capacity in existing cables, according to Telegeography analyst Erik Kreifeldt. Terrestrial links are in demand partly because much of Africa still relies on satellite, which is far more expensive per bit than wired broadband, he said.

Most Internet bandwidth between continents is provided by undersea cables built and financed by groups of service providers. From Africa, most of those links go to Europe. Other carriers pay to tap into those cables and link their customers to the Internet. In some parts of Africa, running cables from coastal areas to the interior is a challenge so satellite remains the major Internet source, Kreifeldt said.

The capacity of international cables landing on African shores is just a fraction of the bandwidth available between Europe, the U.S. and Asia. After seven years of the growth that Telegeography forecasts, from 2012 through 2019, Africa will have 17.2Tbps (bits per second) of links to the outside world. That’s up from just 957Gbps in 2012 but will still be only about one-quarter of the international capacity of Latin America and less than that of Canada, according to Telegeography.

The hunger for the Internet varies among African countries. Through 2019, bandwidth demand is expected to grow fastest in Angola, at 71 percent per year; Tanzania, at 68 percent; and Gabon, at 67 percent.

Many new cables have been built to Africa and around the continent in the past several years, giving service providers excess fiber capacity that can be turned on when needed, Kreifeldt said. As that fiber gets lit up and supply rises, prices should fall for enterprises and other users in African countries, he said. However, due to relative scarcity, a given amount of bandwidth between Africa and Europe costs about 10 times as much as the same size connection between Europe and North America, he said. Africa’s bandwidth gains aren’t expected to shrink that gap.
