RONOG4 meeting in Bucharest, Romania

The 4th edition of Romanian NOG (RONOG) is being held today, 31 October 2017, in Bucharest, Romania, and as the largest meeting of Internet technology professionals in Romania it is expecting to hit over 170 attendees.

As specified in the meeting agenda, I’ll deliver my talk about NAT64 experiments in the go6lab and also one very useful tool that came out of this testing – NAT64Check. I also have the honour of chairing the IPv6/IOT session.

I’m looking forward to being back in Bucharest and if you happen to be at RONOG4, please come and find me in the hallways as I’m always happy to chat about technology, IPv6, DNSSEC, DANE and everything else that makes our Internet a bit of a better place!

How GlaxoSmithKline is Accelerating Science with Docker Enterprise Edition

GlaxoSmithKline is a global pharmaceutical company headquartered in the United Kingdom. Their company mission is “to help people do more, feel better, and live longer”. One way they are doing that is by using data science to find new drug formulations that can improve lives. At DockerCon Europe, Ranjith Raghunath, the director of Big Data Solutions and Lindsay Edwards, the head of Respiratory Data Sciences at GlaxoSmithKline presented how Docker Enterprise Edition (Docker EE) is helping them accelerate drug discovery through a project called Edge Node On Demand.

Letting Science Drive Technology at GlaxoSmithKline

Leveraging Data Science for Improved Outcomes

The biggest challenge in pharmaceutical research is that hundreds of drugs formulations need to be created to take one successfully to market only 3% of formulated molecules actually become medicine. Lindsay Edwards heads a Data Science group that is focused on respiratory illnesses like Chronic Obstructive Pulmonary Disease (COPD) and asthma. His group uses big data analytics to mine research data and previous patient trial data to arrive at results more rapidly.

However, data science is a new and emerging field. There are new software tools and open source data analytics solutions coming to market all the time and different hardware Continue reading

The Tug Of War Between InfiniBand And Ethernet

If you want to get a microcosmic view of the epic battle between Ethernet and InfiniBand (which also includes Omni-Path no matter how much Intel protests) as they relate to high performance computing in its many modern guises, there is perhaps no better place to look at what Mellanox Technologies is selling.

Mellanox, which has been peddling InfiniBand chips, switches, and adapters since the inception of this technology, bought its biggest rival in switch sales, Voltaire, for $218 million back in November 2010. And that was perhaps its smartest move right up to the moment where the company launched …

Network Automation Engineer Persona: Targeted Learning

The series of Network Automation Engineer (NAE) Persona blog posts have churned some comments in the community around learning. Part of the feedback appears to be the hero syndrome fighting back and also the odd misunderstanding, which might be a result of fear. Change often results in fear, so this is natural.

Network Heroes

Some people love networking because it makes them feel special. Some people have got used to that special feeling and hang on to the fact that they’re 

important
. These network engineers feel like a “Packet Lord”.

Automation is designed to remove from humans deterministic and testable tasks. One result is fewer self-titled “Prime minister of Packets” and fewer bottlenecks. Taking IaC (Infrastructure as Code), it becomes so much simpler to define tasks, implement them and test for success or failure. Dealing with sources of truth is part of the natural flow of the process instead of an afterthought on a Friday afternoon.

The hero very much becomes the norm at this point.

At a high level, the articles discuss the evolving NAE persona and not what you should or shouldn’t learn. The articles do not discourage learning, they recognise and promote learning. After all, you Continue reading

IDG Contributor Network: Zombie companies are everywhere! But there’s a cure

It’s zombie season again! Not only was The Walking Dead back with new episodes this month, but neighborhoods around the country are about to be crawling with zombies (most can be staved off with a little chocolate).In business, unfortunately, zombie season has been in full swing for some time. This is an era of digital disruption, and it’s completely changed the way business is done, but not everyone has gotten on board. Companies are persisting with outdated business models, investing in outdated products, and committed to outdated delivery methods. To me, these companies are zombies, dead without knowing it. They may be moving forward, but don’t let the motion fool you, they’re only moving toward obsolescence.To read this article in full or to leave a comment, please click here

Worth Reading: The calm before the IoT Storm (Reaper)

It’s been just over a year since the world witnessed some of the world’s top online Web sites being taken down for much of the day by “Mirai,” a zombie malware strain that enslaved “Internet of Things” (IoT) devices such as wireless routers, security cameras and digital video recorders for use in large-scale online attacks. Now, experts are sounding the alarm about the emergence of what appears to be a far more powerful strain of IoT attack malware — variously named “Reaper” and “IoTroop” — that spreads via security holes in IoT software and hardware. And there are indications that over a million organizations may be affected already. —Krebs on Security

Hybrid Fortran Pulls Legacy Codes into Acceleration Era

GPU accelerated supercomputing is not a new phenomenon with many high performance computing codes already primed to run on Nvidia hardware in particular.

However, for some legacy codes with special needs (changing models, high computational demands), particularly in areas like weather, the gap between those codes and the promise of GPU acceleration is rather large, even with higher level tools like OpenACC to bridge the divide—all without major code rewrites.

Given the limitations of porting some legacy Fortran codes to GPUs, a research team Tokyo Tech has devised what it calls, “hybrid Fortran” which is designed to “increase productivity when …

Applying Software Agility to Network Design

The paper we are looking at in this post is tangential to the world of network engineering, rather than being directly targeted at network engineering. The thesis of On Understanding Software Agility—A Social Complexity Point of View, is that at least some elements of software development are a wicked problem, and hence need to be managed through complexity. The paper sets the following criteria for complexity—

  • Interaction: made up of a lot of interacting systems
  • Autonomy: subsystems are largely autonomous within specified bounds
  • Emergence: global behavior is unpredictable, but can be explained in subsystem interactions
  • Lack of equilibrium: events prevent the system from reaching a state of equilibrium
  • Nonlinearity: small events cause large output changes
  • Self-organization: self-organizing response to disruptive events
  • Co-evolution: the system and its environment adapt to one another

It’s pretty clear network design and operation would fit into the 7 points made above; the control plane, transport protocols, the physical layer, hardware, and software are all subsystems of an overall system. Between these subsystems, there is clearly interaction, and each subsystem acts autonomously within bounds. The result is a set of systemic behaviors that cannot be predicted from examining the system itself. The network design process is, Continue reading

LDP retention and distribution modes

MPLS protocol uses labels to forward traffic between point A and B. These labels are binded to FECs and distributed on the network by means of different protocols like (LDP, RSVP, BGP-LS, SPRING). LDP (Label Distribution Protocol “RFC5036”) is still by far the widely used protocol among them and was developed to do label distribution …
