Intel makes a play for high-speed fiber networking for data centers

Intel is revamping its strategy around the data center by going beyond the Xeon chip and into silicon photonics transceivers. The company announced Monday at the European Conference on Optical Communications (ECOC) that samples of its silicon photonics transceivers targeting 5G wireless infrastructure and data centers are available now, with production set to start in the first quarter of 2019.The company notes that global data center IP traffic is increasing significantly. In 2016, global data center IP traffic was 6.8 zettabytes, and that will triple by 2021 because of all this data generated by humans and the Internet of Things (IoT).The choke point becomes copper wire, the standard for Ethernet connectivity. Copper wire can only effectively transmit about eight to 10 meters, said Eoin McConnell, director of marketing for the connectivity group in Intel’s data center group. Fiber optics can go as far as 10 kilometers.To read this article in full, please click here

BGP Security: A Gentle Reminder that Networking is Business

At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security—specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for… 20 years? … at this point, so I have seen the argument develop across these years many times, and in many ways. What always strikes me about this discussion, whenever and wherever it is aired, is the clash between business realities and the desire for “someone to do something about routing security in the DFZ, already!” What also strikes me about these conversations it the number of times very fundamental concepts end up being explained to folks who are “new to the problem.”

TL;DR
  • BGP security is a business problem first, and a technology problem second
  • Signed information is only useful insofar as it is maintained
  • The cost of deployment must be lower than the return on that cost
  • Local policy will always override global policy—as it should
  • The fear of losing business is a stronger motivator than gaining new business

Why Linux users should try Rust

Rust is a fairly young and modern programming language with a lot of features that make it incredibly flexible and very secure. It's also becoming quite popular, having won first place for the "most loved programming language" in the Stack Overflow Developer Survey three years in a row — 2016, 2017, and 2018.To read this article in full, please click here

IGF 2018: Improvements and a Call for Contributions

The annual meetings of the Internet Governance Forum (IGF) have been consolidated as the main space for discussion and exchange of ideas among the stakeholders of the Internet community on an equal footing. However, there are diverse activities which take place throughout the year that require the participation of all the actors of the community.

The Intersessional Activities

The concept of Dynamic Coalitions (DCs) emerged during the first IGF meeting in 2006. These are informal groups, focused on specific topics that report their activities to the IGF Secretariat each year. Currently, there are 17 active coalitions, which involve diverse topics ranging from accessibility and disability to Internet core values. It is possible to join the work of each of them by accessing the site published by the IGF Secretariat.

On the other hand, following the recommendations of the Working Group on IGF Improvements, the IGF community promoted the creation of the Best Practice Forums (BPFs) as a way to generate more tangible outcomes. For the 2018 cycle, four BPFs were approved; all of them are currently seeking feedback from the community. Some of them have a deadline of September 30, while others will receive contributions until October 15. Continue reading

Gartner – more than a magic quadrant

In the past I have personally given a lot of flack towards Gartner, but that was when I was in a different stage of my career. Over the past two years I’ve transitioned into management, and with that had to learn several valuable lessons. The most important, for me, being expectation management, but that’s for another blog post. The second most important would have to be effectively leveraging resources across all channels. And that’s why I wanted to talk about Gartner.

As an engineer, I found them to be a bit pedantic. They wrote these long winded articles that seemed to never get to the point, i.e. does this product deliver what the company is selling? — A lot of the analysis I’ve seen from Gartner has gotten much better in the past 10-12 years, and while I appreciate that, I think we actually have to thank ourselves for that, rather than Gartner. The freely available content available on blogs, like RouterJockey, has forced anyone hoping to sell content to step up their game. But I digress. My engagements with Gartner always felt generic, I consistently had issues with the amount of knowledge the analyst on the phone had. Continue reading
