In this interview, Srinivas opens up about how data analytics has changed the network operations function, how IoT devices will impact networks, and how analytics can help boost network performance.
I had the opportunity to sit in on a great briefing from Gremlin the other day about chaos engineering. Ken Nalbone (@KenNalbone) has a great review of their software and approach to things here. The more time I spent thinking about chaos engineering and IT, the more I realized that it has more in common with Murphy’s Law that we realize.
If there’s more than one way to do a job and one of those ways will end in disaster, then somebody will do it that way. – Edward Murphy
Anything that can go wrong will go wrong. – Major John Paul Stapp
We live by the adage of Murphy’s Law in IT. Anything that can go wrong will go wrong. And usually it goes wrong at the worst possible time. Database query functions will go wrong when you need them the most. And usually at the height of something like Amazon Prime Day. Data center outages only seem to happen at 4 am on a Sunday during a holiday.
But why do things go wrong like this? Is it because the universe just has it out for IT people? Are we Continue reading
BGP Route Reflection solves a fundamental problem in iBGP operation but introduces some tradeoffs to consider when implementing. In this Network Collective short take, Russ details these tradeoffs and some potential ways to mitigate unintended consequences.
The post Short Take – BGP Optimal Route Reflection appeared first on Network Collective.
The company says its newly formed Access Networks organization will help it win 5G contracts and battle against rivals Ericsson, Huawei, ZTE, and Samsung.
France tackles the Internet: The French government has been making news in recent days for examining ways to regulate the Internet. Its parliament has passed a controversial new law that would allow judges to order the immediate removal of online articles they deem to be fake news, Euronews.com reports. Critics warned the law, which allows for jail sentences for fake news creators, could lead to censorship.
Regulation or autocracy? French President Emmanuel Macron pushed the fake news law, and he also called for more government regulation of the Internet at a recent Internet Governance Forum in Paris. Macron called for international cooperation on Internet issues, as a way to tame disinformation, with CFR.org suggesting governments must adapt to fight modern problems. But TechDirt suggested Macron was acting like an autocrat in his call for more regulation.
Broadband plan MIA: Canada’s government, meanwhile, has “no plan” to bring broadband to rural and remote areas, a government auditor said. Canada’s rural broadband efforts so far have led to “a series of moving targets, lofty proclamations, piecemeal programs, and ultimately big letdowns,” Motherboard says.

Top network transport factors include high packet loss, high latency, high jitter, network path changes, Wi-Fi system performance, and insufficient network bandwidth.
The end of the year has been very busy, with Internet Society staff members speaking at many events on data protection, security-by-design, and the Internet of Things (IoT). First, to recap the last month, you might want to read the Rough Guide to IETF 103, especially Steve Olshansky’s Internet of Things post. Dan York also talked about DNSSEC and the Root KSK Rollover at ICANN 63, and there were several staff members involved in security, privacy, and access discussions at the Internet Governance Forum. In addition, we submitted comments on NIST’s white paper on Internet of Things (IoT) Trust Concerns; the NTIA RFC on Developing the Administration’s Approach to Consumer Privacy; and the NIST draft “Considerations for Managing Internet of Things (IoT) Cybersecurity and Privacy Risks”.
We also have several speaking engagements coming up in the next few weeks. Here’s a quick rundown of the events.
6th National Cybersecurity Conference
27-28 November
Mona, Jamaica
The Mona ICT Policy Centre at CARIMAC, University of the West Indies is hosting the 6th National Cyber Security Conference. The Conference theme this year is “Data Protection – Securing Big Data, Understanding Biometrics and Protecting National ID Systems.” Continue reading
David Gee decided to talk about hygiene of network automation in the Spring 2019 Building Network Automation Solutions online course, and (not surprisingly) Christoph Jaggi wanted to know more:
You highlight the hygiene of automation. What is it and why does it matter?
Hygiene is the important but boring bit of automation most beginners and amateurs pass by.

Reaching agreement (consensus) is hard enough, doing it in the presence of active adversaries who can tamper with or destroy your communications is much harder still. That’s the world of Byzantine fault tolerance (BFT). We’ve looked at Practical BFT (PBFT) and HoneyBadger on previous editions of The Morning Paper. Today’s paper, BEAT, builds on top of HoneyBadger to offer BFT with even better latency and throughput.
Asynchronous BFT protocols are arguably the most appropriate solutions for building high-assurance and intrusion-tolerant permissioned blockchains in wide-are (WAN) environments, as these asynchronous protocols are inherently more robust against timing and denial-of-service (DoS) attacks that can be mounted over an unprotected network such as the Internet.
The best performing asynchronous BFT protocol, HoneyBadger, still lags behind the partially synchronous PBFT protocol in terms of throughput and latency. BEAT is actually a family of five different asynchronous BFT protocols that start from the HoneyBadger baseline and make improvements targeted at different application scenarios.
Unlike HoneyBadgerBFT, which was designed to optimize throughput only, BEAT aims to be flexible and versatile, providing protocol instances optimized for latency, throughput, bandwidth, or scalability (in terms of the number Continue reading
I work in Developer Relations at Cloudflare and I'm fortunate to have top-notch developers around me who are willing to share their knowledge with the greater developer community. I produced a series of events this autumn called Real World Serverless at multiple locations around the world and I want to share the recorded videos from these events.
Our Austin Real World Serverless event (in partnership with the ATX Serverless User Group Meetup) included two talks about Serverless technology featuring Victoria Bernard and Preston Pham from Cloudflare. They spoke about working out backend knots with Workers and building a router for the great good.
Working out Backend Knots with Workers - Victoria Bernard (0:00-15:19)
Cloudflare Workers is a platform the makes serverless development and deployment easier than ever. A worker is a script running between your clients' browsers and your site's origin that can intercept requests. Victoria went over some popular use cases of how proxy workers can dramatically improve a site's performance and add functionality that would normally require toying with complicated back-end services.
Build a Router for Great Good - Preston Pham (15:20-33:53)
Serverless computing is great, but requires routing or some kind of API Continue reading
Last week, 760 humans from Singapore, London, Beijing, Sydney, Nairobi, Austin, New York, Miami, Washington DC, Warsaw, Munich, Brussels, and Champaign reunited with their San Francisco counterparts for our 9th annual Cloudflare company retreat in the San Francisco Bay Area. The purpose of the company retreat is to bring all global employees together under one roof to bond, build bridges, have fun, and learn – all in support of Cloudflare’s mission to help build a better Internet.
It’s easy to write off corporate retreats as an obligatory series of meetings and tired speeches, but Cloudflare’s retreats are uniquely engaging, personalized, fun, and inspiring. Having grown with Cloudflare over the last year (I started just before our 2017 retreat), I wanted to share some of my experiences to highlight Cloudflare’s incredible culture.
The office was buzzing with different languages and laughter as people hugged and shook hands for the first time after working online together for a year or more. Everyone’s Google calendar looked like a rainbow as we each mined for white space to squeeze in those coveted 1:1s, all-hands presentations, and bowling offsites with our global colleagues. The buses and Google chats felt like summer camp, with people claiming Continue reading
