IBM ends China’s 5-year reign atop supercomputer rankings

There’s a shake-up – and a scandal – in the Top500 ranking of the world’s most powerful supercomputers.The U.S. has retaken first place in the Top500 list after five years of dominance by China. Computers built by IBM for the U.S. Department of Energy have pushed the previous two record-holders, both Chinese, into second and fourth place.[ Now see who's developing quantum computers.] But the previous fourth placeholder, Japan’s Gyoukou, is nowhere to be found, after one of its creators was arrested on suspicion of fraud.To read this article in full, please click here

Routing Security & IPv6 at NANOG 73 in Denver

We’ll be at NANOG 73 in Denver, CO, USA this week talking about routing security, MANRS, and IPv6.

The North American Network Operators Group (NANOG) is the professional association for Internet engineering, architecture and operations. Its core focus is on continuous improvement of the data transmission technologies, practices, and facilities that make the Internet function. NANOG meetings are among the largest in the region, bringing together top technologists on a wide range of topics.

Routing Security

On Tuesday, 26 June, at 1:30PM, Andrei Robachevsky will give a talk called, “Routing Is At Risk. Let’s Secure It Together.”

From the session abstract:

“Stolen cryptocurrency, hijacked traffic blocking access to whole countries, derailing vital Web resources for thousands of people. Routing used to fly under the radar. As long as incidents weren’t too bad, no one asked too many questions, and routing security never made it to the top of the to-do list. But these days, routing incidents are regularly making the news, executives are getting nervous, and engineers are under pressure to make sure their network isn’t next. The problem is, you cannot secure your own network entirely by yourself. But you can help secure the global routing system Continue reading

Network Notes: RIP

Routing information protocol (RIP) is a interior distance vector routing protocol originally defined in RFC1058. RIP has had a number of improvements over the years with version 2 being defined RFC2453 and RIPng adding IPv6 support in RFC2080. Transport RIPv1 and RIPv2...continue reading

Routing Loop, Failure by Design

I have spent some time studying the CCDE materials. One broken design example that has come up involves route reflector clients that don’t align with the physical topology. This article examines that example and some solutions to the problem.

To illustrate this example we have built the topology below. I used loopback addresses 1.1.1.1 through 6.6.6.6 (based on csr1000v-x). The router on the top is a eBGP neighbor with csr1000v-1 and csr1000v-2. The four routers forming a square in the center have an initial configuration of OSFP and BGP (iBGP as shown). Both Route Reflectors are peered with both clients.

Watch Live On Monday, 25 June – DNSSEC Workshop at ICANN 62 in Panama

With the DNSSEC Root Key Rollover coming up on October 11, how prepared are we as an industry? What kind of data can we collect in preparation? What is the cost benefit (or not) of implementing DANE? What can we learn from an existing rollover of a cryptographic algorithm?

All those questions and more will be discussed at the DNSSEC Workshop at the ICANN 62 meeting in Panama City, Panama, on Monday, June 25, 2018. The session will begin at 9:00 and conclude at 12:15 EST (UTC-5). [Note: this is one hour different than current US Eastern Daylight Time – Panama does not change to daylight savings time – and so this will begin at 10:00 EDT (UTC-4).]

The agenda includes:

• DNSSEC Workshop Introduction, Program, Deployment Around the World – Counts, Counts, Counts
• Panel: DNSSEC Activities and Post Key Signing Key Rollover Preparation
• DANE: Status, Cost Benefits, Impact from KSK Rollover
• An Algorithm Rollover  (case study from CZ.NIC)
• Panel: KSK Rollover Data Collection and Analysis
• DNSSEC – How Can I Help?
• The Great DNSSEC/DNS Quiz

It should be an outstanding session!  For those onsite, the workshop will be in Salon 4, the ccNSO room.

Weekend Reads 062218: Bitcoin and Security Flaws

But, as with all new technology, security risks can be found beneath the hype. Indeed, threat actors are finding new targets amid the rise of blockchain as they serve up social-engineering attacks, malware, and exploits to businesses and consumers, according to a recently published report by McAfee’s Advanced Threat Research Team. —Kelly Sheridan @Dark Reading

After last Thursday’s regulatory news that bitcoin and ether were not considered securities, which was widely considered a win for crypto enthusiasts, digital currencies had failed to hold on to gains, a sign the bear market is firmly intact. However, investors were hoping Monday’s move above the post-SEC-statement high will be the start of a more fruitful period for digital currency owners. —Aaron Hankin @MarketWatch

Dubbed Lazy FP State Restore, the vulnerability (CVE-2018-3665) within Intel Core and Xeon processors has just been confirmed by Intel, and vendors are now rushing to roll out security updates in order to fix the flaw and keep their customers protected. The company has not yet released technical details about the vulnerability, but since the vulnerability resides in the CPU, the flaw affects all devices running Intel Core-based microprocessors regardless of the installed operating systems, except some modern versions of Continue reading

IDG Contributor Network: Welcome to the edge era: where a second lost on the network has insurmountable consequences

The next great leap forward in progress will be marked by an exponential growth in connection and connectivity. As sensors become smaller and more energy efficient, mobile devices become more capable and our networks become more robust, industries as disparate as healthcare, transportation, education, government and entertainment will find opportunities for new efficiencies, new ways of interacting with consumers and transformative approaches to serving their communities.In short, advancements in network technology are helping us achieve great things. We’re seeing the well documented benefits of agility, reliability and performance of networks in healthcare, where wireless networks are supporting complex EHR systems and M2M communications are delivering moment-to-moment information on patient status and improving health outcomes. There’s also been an emergence of new educational (and job) opportunities provided via emerging eSports programs in K-12 and higher education settings.To read this article in full, please click here

Leveling Up Women One Edit at a Time

Only 1 in 10 Wikipedia editors is a woman. Unfortunately, the underrepresentation of female perspectives is quite common within the tech world. In order to help achieve gender equality in content creation and dissemination, Wikipedia Editathons are held as a way of bridging the gap and encourage female editors to increase the coverage of women’s topics.

The Internet Society India Delhi Chapter, in partnership with the Women Special Interest Group and supported by the Wikimedia Foundation, organized the 1st Global Editathon “Girls in ICT” on 28 April, 2018. Various Chapters and groups participated in this event to increase Wikipedia pages about Asian women who have contributed to any technology-related fields.

“Women are seriously underrepresented in Wikipedia’s content,” says Amrita Choudhury, treasurer of the Internet Society India Delhi Chapter. She has over 17 years of experience in IT and the Internet industry and is a member of the SIG Women team. “Exact figures vary depending on which research you’re reading, but only around 17% of individuals profiled on Wikipedia are women.”

What Chapters were involved and how did you work together?

“As devoted to the #ShineTheLight movement, we decided to collaborate with the SIG Women, whose main interest Continue reading
