186Gbps Transfer Sets Real-World Speed Record

186Gbps Transfer Sets a Real-World Fiber Speed RecordResearchers have set a new world record for data transfer. The new record was set at the SuperComputing 2011 (SC11) conference in Seattle, Washington. PhysOrg.com reports the international team set the speed record when they transferred 186 gigabits per second (Gbps) of data across 134 miles of an optical network for 11 hours.

Commercially available circuits

SuperComputing 2011The record-setting connection used a commercially available 100 Gbps circuit. The circuit was set up by Canada’s Advanced Research and Innovation Network (CANARIE) and BCNET, a non-profit, shared IT services organization. PhysOrg says the team was able to reach transfer rates of 98 Gbps between the University of Victoria Computing Center in Victoria, BC, and the Washington State Convention Center in Seattle. With a simultaneous data rate of 88 Gbps in the opposite direction, the team reached a sustained two-way data rate of 186 Gbps between two data centers. This broke the team’s previous peak-rate record of 119 Gbps set in 2009.

California Institute of Technology (Caltech) led the team of high-energy physicists, computer scientists, and network engineers from the University of Victoria, the University of Michigan, the European Center for Nuclear Research (CERN), and other partners.

transport large quantities of data across global networks of optical fibersAccording to PhysOrg, the achievement will help set up new ways to transport increasingly large quantities of data. More and more data traverse continents and oceans via global networks of optical fibers. The next generation of network technology needs new methods to transfer rates of 40 and 100 Gbps—that will be built in the next couple of years.

Our group and its partners are showing how massive amounts of data will be handled and transported in the future,” Harvey Newman, professor of physics and head of the high-energy physics (HEP) team told PhysOrg. “Having these tools in our hands allows us to engage in realizable visions others do not have.”

“The 100 Gbps demonstration at SC11 is pushing the limits of network technology by showing that it is possible to transfer petascale particle physics data in a matter of hours to anywhere around the world,” adds Randall Sobie, a research scientist at the Institute of Particle Physics in Canada and team member told PhysOrg.

The speed record equipment was not sexy

memorex guyExtremeTech points out that the achievement is quite significant. It is significant because the scientists used a commercially available 100 Gbps link and not “over private networks under laboratory/testbed conditions.” The equipment was not particularly sexy either. ExtremeTech lists Dell (DELL) servers with Intel (INTC) Sandy Bridge-based server motherboards with PCIe 2.0 and 3.0 solid-state drives. They used 10 and 40 Gbps LAN connections, and Force10 Z9000 and Brocade (BRCD) MLXe-4 switch-routers. The gear was able to achieve a disk to disk transfer rate of 60 Gbps, around 7.5 gigabytes per second. The 186 Gbps record was a memory-to-memory transfer between the servers. The max per-computer speed was 35 Gbps. Tested.com calculates that 4.42 petabytes traveled across the network during the transfer test.

So why does anyone need to move two million gigabytes per day? This is fast enough to transfer nearly 100,000 full Blu-ray disks—each with a complete movie and all the extras—in a day.

CERN needs faster transfer rates. CERN needs to move the huge amounts of data coming from the Large Hadron Collider (LHC). The LHC has already generated more than 100 petabytes of data. The data is processed, distributed, and analyzed at 300 computing and storage facilities at laboratories and universities around the world. Scientists believe the data volume will rise a thousand-fold as physicists crank up the collision rates and energies at the LHC in their attempt to cause the end of the world (Not)

FierceTelecom predicts that service providers will deploy 100Gig when the price of 100Gig is double the price of 40Gig. They believe that will take place in 2013.

This massive amount of bandwidth running on commodity Internet pipes with available hardware seems to spit in the eye of current bandwidth providers who can’t seem to provide a 10 Mbps circuit reliably.

Flip the Switch on IPv6

Flip the Switch on IPv6World IPv6 day (Which I reported on here) took place in June 2011. Google (GOOG), Facebook, Yahoo (YHOO), and Akamai (AKAM) were among the participants in last year’s new networking dress rehearsal. apparently, everything went well last June.

Internet SocietyNathan Ingraham at The Verge recently noted that IPv6 is now ready for prime-time. The Internet Society announced that the IPv6 switch will be permanently flipped on June 6th, 2012.

The article says a number of major ISPs, networking hardware manufacturers, and web companies pledged support from day one. For starters, four of the biggest web properties will all enable IPv6 permanently:

Cisco logoFrom a hardware perspective, Cisco (CSCO) and D-Link (2332) both committed to enabling IPv6 across their range of home products by June.

GigaOM reports that Akamai (AKAM) and Limelight (LLNW) will also recruit other websites to join the initiative, by implementing IPv6 throughout their content delivery networks.

Several leading ISP’s will enable IPv6 to enough of their customer base that at least one percent of their residential subscribers who visit IPv6 enabled websites;

Spyware Prevention 101

Spyware Prevention 101Spyware goes by many names, including adware, malware, crimeware, scumware, and snoopware. No matter what you call it, spyware’s purpose is still the same: to steal your personal information (PII).

steal your identity, use your credit cards, siphon funds from your bank accountsHelp Net Security says that once hackers have your personal information they can steal your identity, use your credit cards, siphon funds from your bank accounts, and more. Simply put: it’s bad news and you want nothing to do with it.

The good news, according to the article, is that spyware prevention is possible and there are many ways to keep these dangerous programs at bay. In addition to installing the right software, users can practice these computer security tips from Broomfield, CO-based Internet security firm Webroot:

  • Download software directly from the source. The article says a common way to get a spyware infection is to install free or pirated programs from file-sharing sites which have been booby-trapped with malware.
  • Set your browser security settings to “high” and protect yourself from “drive-by” downloads and automatic installations of unwanted programs.
  • Use a firewallAvoid questionable websites, such as those featuring adult material. They’re notorious for spreading spyware threats and causing users problems.
  • Use a firewall.
  • Be suspicious of email and IM.
  • Don’t open attachments unless you know the sender and are expecting a file from them.
  • Delete messages you suspect are spam (don’t even open them).
  • Avoid clicking on links within messages.
  • do not click on a link embedded in the email messageDo not give personal information to unsolicited requests even if they seem legitimate.
  • If you receive a request for personal information from your bank or credit card company, contact that financial institution directly, but do not click on a link embedded in the email message.

Amichai Shulman – CTO, Imperva posted that the credentials to a Hotmail account are worth $1.50 and a Gmail account is worth over $80 to cyber-criminals. Gmail is more valuable to the attacker because of the wide variety of other Gmail cloud services that can be accessed through Gmail credentials.

It is also likely that credentials used by a person for one application will most work on other applications as well. It is not uncommon for people to have the same username and password used for their Facebook account, their Twitter account, their Airline Frequent Flyer account, or any application that uses their Gmail account as the application account name.

That’s why spyware is bad.

Packet Pushers Podcast

Now that Spring has magically erupted here and I no longer have to white-knuckle my daily commute thru ice and snow and rain sometimes in the same drive, I can starting listening to the Packet Pushers Podcast’s again. The podcasts help me keep my tech info up to date as I get more deeply involved in the business side of IT. It is also good to hear global opinions on tech.

Packet Pushers Podcast

On the podcast, they talk about routing, switching, security, firewalls, data center, and industry trends in a round table format. According to the website, topics can be “deep-dived” where they focus on practical technology issues, or they sometimes review the latest announcements from vendors and discuss the technologies.
