Google, Facebook promise new IPv6 services after successful trial
Google leaves IPv6 on for YouTube; Facebook adds IPv6 to developers' site; Yahoo sees 'minimal risk' to IPv6
One day after completing a successful 24-hour trial of IPv6, Facebook, Google and Yahoo said at a joint press conference that they would begin permanently supporting this upgrade to the Internet's main communications protocol on some of their key websites.
Joined by two content delivery networks -- Akamai and Limelight, which also pledged their commitment to IPv6 deployment -- these popular websites proclaimed the World IPv6 Day trial to be a resounding success. All three companies said they had handled a significant increase in IPv6 traffic on June 8 without suffering serious technical glitches.
IPv6 features an expanded addressing scheme, so it can handle vastly more devices connected directly to the Internet than its predecessor called IPv4. However, IPv6 is not backward compatible with IPv4, which means website operators have to upgrade their network equipment and software to support IPv6 traffic.
Google said it has decided to leave its main YouTube website enabled for IPv6 for the time being. Since 2008, Google has supported IPv6 on separate websites -- such as www.ipv6.google.com -- rather than on its main websites.
"We saw 65% growth in our IPv6 traffic on World IPv6 Day," said Lorenzo Colitti, IPv6 Software Engineer at Google, who pointed out that Google added IPv6 support to several new services including Orkut for the trial. "This event has really been successful in galvanizing the community."
"At Facebook, we saw over 1 million of our users reach us over IPv6," said Don Lee, senior network engineer at Facebook. "There were no technical glitches in this 24-hour period. We were encouraged by the many positive comments on our blog. ... It is really interesting to see how passionate people were about IPv6 around the world."
Because of the positive results from World IPv6 Day, Facebook has decided to support IPv6 on its Website for developers, which is www.developers.facebook.com.
"We will continue to adapt our entire code base to support IPv6," Lee added. "IPv6 will allow the Internet to continue its amazing development."
BY THE NUMBERS: IPv6 traffic surges at launch of World IPv6 Day
World IPv6 Day was held yesterday and was sponsored by the Internet Society. The event attracted 400-plus corporate, government and university participants that deployed IPv6 on more than 1,000 websites for the day.
Leslie Daigle, chief Internet technology officer for the Internet Society, said World IPv6 Day was designed to motivate service providers, website operators, hardware makers and software suppliers to test-drive IPv6 and to identify any remaining technical issues that need to be resolved with this emerging technology.
"It was perceived to be quite a successful day," Daigle said. "It was an amazing display of cross-industry participation. ... It's an important step in the Internet's progress. We are running out of IPv4 addresses, and IPv6 is definitely the way to move forward to make sure the Internet is a platform for innovation."

Active Directory Federation Services 2.0 - Glossary
This topic contains definitions of key terms that are used in customizing Active Directory® Federation Services (AD FS) 2.0.
claim
A statement about a subject; for example, a name, identity, key, group, permission, or capability, made by one subject about itself or another subject. Claims are given one or more values and then packaged in security tokens that are issued by a security token service (STS).
claim type
The type of statement in the claim being made. Example claim types include FirstName, Role, and PPID. The claim type provides context for the claim value.
claim value
The value of the statement in the claim being made. For example, if the claim type is FirstName, a value might be Matt.
claims provider
A claims provider is a type of identity provider that provides single sign-on functionality between an organization and other identity providers and relying parties.
identity provider
An organization issuing claims in security tokens. For example, a credit-card provider organization might issue a claim in a security token that enables payment if the relying party application requires that information to complete an authorized transaction.
identity provider – security token service (IP-STS)
A software component or service that is used by an identity provider that issues claims and packages them in security tokens.
information card
A visual representation of an identity with associated metadata that may be selected by a user in response to an authentication request.
managed information card
An information card provided by an external identity provider. By using managed cards, identity information is stored with an identity provider.
relying party
An application that relies on security tokens and claims issued by an identity provider.
security token
An on-the-wire representation of claims that has been cryptographically signed by the issuer of the claims, providing strong proof to any relying party as to the integrity of the claims and the identity of the issuer.
security token service (STS)
A Web service that issues claims and packages them in encrypted security tokens (see WS-Security, WS-Trust).
web single sign-on (SSO)
A process enabling partnering organizations to exchange user authentication and authorization data. By using Web SSO, users in partner organizations can transition between secure Web domains without having to present credentials at each domain boundary.
Windows® CardSpace™ 2.0
Windows® CardSpace™ 2.0 is Microsoft's implementation of an Information Card selector for Microsoft Windows. See Information Card.
WS-Federation
The WS-Federation standard defines mechanisms that are used to enable identity, attribute, authentication, and authorization federation across different trust realms. For more information about WS-Federation, see Understanding WS-Federation at the MSDN Web site.
WS-Federation passive requester profile
WS-Federation Passive Requester Profile describes how the cross trust realm identity, authentication, and authorization federation mechanisms defined in WS-Federation can be utilized used by passive requesters such as Web browsers to provide Identity Services. Passive requesters of this profile are limited to the HTTP protocol. For more information about WS-Federation Passive Requester Profile, see the specification at the MSDN Web site.
WS-Security
The WS-Security standard consists of a set of protocols designed to help secure Web service communication using SOAP. For more information about WS-Security, see the OASIS site for the WS-Security standard.
WS-Trust
A standard that takes advantage of WS-Security to provide Web services with methods to build and verify trust relationships. For more information about WS-Trust, see the OASIS site for the WS-SX standard, which includes WS-Trust.

Microsoft at E3 2011: Halo 4 out 2012
E3 2011: New Fable and Kinect experiences wow the LA crowds
Microsoft has kicked off E3 2011 in style in Los Angeles today, with a slew of new announcements and demonstrations of exclusive games and services for Xbox 360 and Kinect. And, as was expected and hoped, a final reveal that Halo 4 is on the way soon.
Following a momentous opening marked by a demo of Activision's forthcoming Call of Duty: Modern Warfare 3, and a demonstration of the forthcoming new TV and voice search features on the way to Xbox 360 later in 2011, Microsoft gave the hardcore crowd exactly what they were hoping for.
Loads of decent new games
The Xbox 360 maker is the first of the three major console manufacturers to lay its cards on the table at this year's massive gaming industry trade event, opening E3 2011 in some style, and with an almost confident swagger.
A solid range of developers took to the stage to demo loads of new and exclusive games set to arrive on Xbox 360 and Kinect later this year and next, including (in no particular order) the aforementioned Halo 4 and COD: Modern Warfare 3 along with Gears of War 3, Forza 4, Fable: The Journey, Minecraft (yes!) and a ton of other new triple-A content.
Firstly, following a quick UFC for Xbox Live announcement to please the wrestling fans, and a first look at Crystal Dynamic's new Tomb Raider title (due late 2012) Microsoft Studios Phil Spencer took to the stage to assure the audience that every single game they were showing from this point onwards in the presser was an Xbox 360 exclusive.
Starting with one of the biggest and most highly-anticipated 360 games of the year, Epic Games' CliffyB took to the E3 stage to give the latest demo of the next version of much-loved muscle-men sci-fi shooter Gears of War 3.
The Epic rep gave rap legend Ice-T a run through some of the new aspects of the co-op gameplay in the game. Nothing really new seemed to be on show in terms of the gameplay demonstrated, but why fix it when it's clearly not broke (and hugely popular)?
Following the latest Gears demo, cutting edge developers Crytek were next up to show off a title called Ryse, which will let you use Kinect motion-control for melee combat.
After that short demo, the new HD remake of the original Halo: Combat Evolved, with improved graphics and new Xbox Live maps was shown off, to the requisite whoops from the series' many fans in the crowd.
Halo: Combat Anniversary is set to be released on November 15th. A must-buy game for anybody that never got to play the original (and, most likely, a must-buy game for a large proportion of those gamers that did play the original as well).
Kinect'ing with the hardcore
Following that slew of sci-fi shooters, the latest demo of every Xbox-360-owning petrolhead's favorite Forza 4 is shown off, with the announcement that the demo was all in-game footage causing jaws to drop amongst many in the audience.
Plus, as rumoured, Kinect voice control and head-tracking features are also confirmed for the new Forza, in addition to full 16-player online multiplayer and an impressive list of 80 car manufacturers all signed up to the game, which releases on October 11 later this year.
Next up, as expected, Lionhead boss (and Microsoft Gaming Studios' creative director) Peter Molyneux took to the stage to introduce his next major Xbox 360 game, Fable: The Journey.
Kinect control is clearly going to play a major part in Molyneux's new game, as he demonstrated the games' young protagonist controlling a gypsy caravan and casting spells merely by hand movements and gestures recognised by Kinect. The impressive new Fable demo draws cheers and applause from the appreciative crowd.
Finally, just to confirm that Kinect is being developed firmly with hardcore gamers and games developers in mind, Microsoft announce that PC gaming favourite Minecraft will be heading to the Xbox 360 with Kinect support later in 2011. A very savvy - and very cool - move indeed.
