Rough Guide to IETF 100: Internet of Things

The Internet of Things (IoT) is a major buzzword around the Internet industry and the broader technology and innovation business arenas. We are often asked what the IETF is doing in relation to IoT and in this Rough Guide to IETF 100 post I’d like to highlight some of the relevant sessions scheduled during the upcoming IETF 100 meeting in Singapore. Check out the IETF Journal IoT Category, the Internet Society’s IoT page, or the Online Trust Alliance IoT page for more details about many of these topics.

The Thing-to-Thing Research Group (T2TRG) investigates open research issues in turning the IoT into reality. The research group will be holding a half-day joint meeting with the Open Connectivity Foundation (OCF) on the Friday before IETF, and they will also be meeting on Tuesday afternoon in Singapore to report out on their recent activities. Included on the agenda is the upcoming Workshop on Decentralized IoT Security and Standards (DISS). This workshop will be held in conjunction with the Network and Distributed System Security (NDSS) Symposium on 18 February 2018 in San Diego, CA, USA. The DISS workshop will gather researchers and the open standards community together to help address Continue reading

Qualcomm’s Amberwing Arm Server Chip Finally Takes Flight

It is going to be a busy week for chip maker Qualcomm as it formally jumps from smartphones to servers with its new “Amberwing” Centriq 2400 Arm server processor during the same week that it has received an unsolicited $130 billion takeover offer from sometimes rival chipmaker Broadcom.

The Centriq 2400 is the culmination of over four years of work and investment, which according to the experts in the semiconductor industry we have talked to, easily took on the order of $100 million to $125 million to make happen ­– remember there was a prototype as well as the …

Arm Smooths the Path for Porting HPC Apps

One of the arguments Intel officials and others have made against Arm’s push to get its silicon designs into the datacenter has been the burden it would mean for enterprises and organizations in the HPC field that would have to modify application codes to get their software to run on the Arm architecture.

For HPC organizations, that would mean moving the applications from the Intel-based and IBM systems that have dominated the space for years, a time-consuming and possibly costly process.

Arm officials over the years have acknowledged the challenge, but have noted their infrastructure’s embrace of open-source software and …

ARM Takes Wing: Qualcomm vs. Intel CPU comparison

One of the nicer perks I have here at Cloudflare is access to the latest hardware, long before it even reaches the market.

Until recently I mostly played with Intel hardware. For example Intel supplied us with an engineering sample of their Skylake based Purley platform back in August 2016, to give us time to evaluate it and optimize our software. As a former Intel Architect, who did a lot of work on Skylake (as well as Sandy Bridge, Ivy Bridge and Icelake), I really enjoy that.

Our previous generation of servers was based on the Intel Broadwell micro-architecture. Our configuration includes dual-socket Xeons E5-2630 v4, with 10 cores each, running at 2.2GHz, with a 3.1GHz turbo boost and hyper-threading enabled, for a total of 40 threads per server.

Since Intel was, and still is, the undisputed leader of the server CPU market with greater than 98% market share, our upgrade process until now was pretty straightforward: every year Intel releases a new generation of CPUs, and every year we buy them. In the process we usually get two extra cores per socket, and all the extra architectural features such upgrade brings: hardware AES and CLMUL in Westmere, Continue reading

Researchers developing building-free data centers

Servers should be stored in vats of cooling, non-conductive oil instead of elaborate, outfitted structures, say engineers who are working on a radical, building-free, data center concept.French company Horizon Computing is one of the developers behind the project and provides support. It proposes using stacks of 10-gallon barrels filled with Shell DIALA dielectric mineral oil or natural equivalent. Dielectric oil doesn’t have any water in it, so it won’t conduct electricity, but it cools just like water. The computers function as normal and aren’t subject to rust either.Benefits of RuggedPOD containers The idea is that common servers are fully submerged in the barrels where they are chilled by the immersion. Expensive humidity control and air conditioning thus become irrelevant, as do buildings.To read this article in full or to leave a comment, please click here

What to consider when deploying a next-generation firewall

Firewalls have become ubiquitous across enterprises over the past decade, but the combination of new and varied access methods combined with increasingly sophisticated attacks has forced network operators and security professionals to constantly evaluate their defenses. Typically, firewalls are on a five-year refresh cycle, according to Gartner researcher Adam Hils, and that gives organizations the opportunity to evaluate fairly regularly what type of firewall and what features best suit their needs.+MORE AT NETWORK WORLD: What is a firewall? +To read this article in full or to leave a comment, please click here

IDG Contributor Network: Why your company can be sued for using SD-WAN

When you buy your SD-WAN, or for that matter any WAN technology, you sort of assume that the vendor has the legal right to sell it to you.But what happens if they don’t? What happens if you’ve built your WAN on an illegally acquired technology?The question is not just theoretical. Last week, FatPipe sent me a press release pointing out how United States PTO Patent Court upheld a signature claim to its U.S. patent (number 6,775,235) for load balancing across disparate networks. Load balancing is a critical component of all SD-WAN products. As such, FatPipe could, in theory, claim licensing fees from SD-WAN players and their users.To read this article in full or to leave a comment, please click here

Cumulus Linux + Voyager — Bringing cost-effective scalability to internet infrastructure

We’re thrilled to announce that Facebook has partnered with Cumulus Networks to bring you the industry’s first open optical routing platform loaded with Cumulus Linux. That’s right, Cumulus Networks is branching into some exciting new territory (a new voyage… if you will). We couldn’t be more honored and excited to work closely with Facebook to bring scalability and cost-effective hardware and software to the optical space — an industry that is growing rapidly.

Bandwidth for Internet services is becoming a more tangible challenge every single day, but the current proprietary solutions are too expensive and do not scale. As Facebook explained, “the highest-performing ‘bandwidth and reach’ are still fiber-based technologies — in particular, switching, routing, and transport DWDM technologies.” With the popularity of services that require a lot of bandwidth, like VR and video, there has become a critical need for better backhaul infrastructure that is cost-effective and scalable and supports high-performing wireless connectivity. The issue becomes even more critical when considering a variety of geographic conditions. For instance, rural regions need long backhaul pipes, which is cost-prohibitive.

That’s where Voyager comes in. Voyager was designed to bring the Internet to everyone — from dense urban locations to remote Continue reading

Worth Reading: The ROCA Encryption Vulnerability

Yes. It’s serious in practice and in principle. Infineon used a flawed key generation routine, which means those keys are easier to crack, and the routine is used in chips embedded in a wide variety of devices. It’s reckoned that the flawed routine has been in use since 2012 and has probably been used to generate tens of millions of keys. Naturally, many of those keys will have been generated precisely because someone had data or resources that they particularly wanted to secure. –Robin Wilton @ The Internet Society
