Survey Paints A Bleak Picture of the Current State of Trust Online

The 2017 CIGI-Ipsos Global Survey on Internet Security and Trust paints a bleak picture of the current state of trust online. A majority of those surveyed said they are more concerned about their privacy than the year before, with an almost even split between those “much more concerned” and those only “somewhat more concerned”. When asked whether they agree with the statement “overall, I trust the Internet”, only 12% of respondents strongly agreed and a further 43% somewhat agreed. This means only a little more than half agreed that they trust the Internet, and some even expressed some reservation by choosing to respond “somewhat agree”.

Comparing Docker deployment options in public cloud

Few weeks back, I did a presentation in Container conference, Bangalore comparing different solutions available to deploy Docker in the public cloud. Slides are available here. I have also put the steps necessary along with short video for each of the options in the github page here. Abstract of the talk: Containers provide portability for … Continue reading Comparing Docker deployment options in public cloud

Trump claimed on Earth Day: ‘Rigorous science is critical to my administration’

If you had been living under a rock, then you might actually believe that President Trump plans to protect the environment and support science.Trump’s Earth Day statement began: Our Nation is blessed with abundant natural resources and awe-inspiring beauty. Americans are rightly grateful for these God-given gifts and have an obligation to safeguard them for future generations. My Administration is committed to keeping our air and water clean, to preserving our forests, lakes, and open spaces, and to protecting endangered species.To read this article in full or to leave a comment, please click here

Sharing state between host and upstream network: LACP part 3

So far in the previous articles, we’ve covered the initial objections to LACP a deep dive on the effect on traffic patterns in an MLAG environment without LACP/Static-LAG. In this article we’ll explore how LACP differs from all other available teaming techniques and then also show how it could’ve solved a problem in this particular deployment.

I originally set out to write this as a single article, but to explain the nuances it quickly spiraled beyond that. So I decided to split it up into a few parts.
Part1: Design choices – Which NIC teaming mode to select

Part2: How MLAG interacts with the host
• Part3: “Ships in the night” – Sharing state between host and upstream network

Ships in the night

An important element to consider is LACP is the only uplink protocol supported by VMware that directly exchanges any network state information between the host and its upstream switches. An ESXi host is also sortof a host, but also sortof a network switch (in so far as it does forward packets locally and makes path decisions for north/south traffic); here in lies the problem, we effectively have network devices forwarding packets between each other, but Continue reading

There’s now a tool to test for NSA spyware

Has your computer been infected with a suspected NSA spying implant? A security researcher has come up with a free tool that can tell.Luke Jennings of security firm Countercept wrote a script in response to last week’s high-profile leak of cyberweapons that some researchers believe are from the U.S. National Security Agency. It's designed to detect an implant called Doublepulsar, which is delivered by many of the Windows-based exploits found in the leak and can be used to load other malware.To read this article in full or to leave a comment, please click here

Self Driving Cars and Network Automation

Last year at Interop, there was a great mini-conference dedicated to the DevOps for Networking community. In that session, I kicked off the day with a general view of where the industry was with respect to the intersection of DevOps and networking with a focus on network automation.

One of the analogies I made was comparing network automation to self-driving cars posing the question, “Are they real?”…“Are they real for us (the consumer)?”

Self-Driving Cars

No, they are not, but I continued to make the analogy. Is complete network automation real today? While, the answer is yes, it’s not really a reality for most…yet.

So, what’s the connection between self-driving cars and network automation?

Start small and expand. Pick a problem, solve it, and integrate it.

Self-Driving Cars are Coming

While self-driving cars aren’t a reality for us to buy and purchase today, intelligent cars are– these are cars that have high-value services and features enhancing the way we drive, our safety, and much more generally, the way we in which we consume the streets and infrastructure around us.

Intelligent Cars

These include automated features like self-parking, back-up cameras, automated beeping as you back-up, automatic-brakes, GPS, and computer systems that give Continue reading

Join forces to eliminate spam – read the new report from the CRTC

What are the best ways to reduce spam? How can we work together to reduce this threat and create a more trusted Internet? 

Last October, in the vibrant city of Bangkok, the Internet Society joined regulators for an in-depth conversation about how to eliminate spam and its harmful effects. Our kind hosts were the Canadian Radio-television and Telecommunications Commission (CRTC) and the International Institute of Communications (ICC).

The Future Of SDN Is Up In The Air

The announcement this week that Riverbed is buying Xirrus was a huge sign that the user-facing edge of the network is the new battleground for SDN and SD-WAN adoption. Riverbed is coming off a number of recent acquisitions in the SDN space, including Ocedo just over a year ago. So, why then, would Riverbed chase down a wireless company when they’re so focused on the wiring behind the walls?

The New User Experience

When SDN was a pile of buzzwords attached to an idea that had just come out of Stanford, a lot of people were trying to figure out just what exactly SDN could offer them in terms of their network. Things like network slicing were the first big pieces to be put up before things like orchestration, programmability, and APIs were really brought to the fore. People were trying to figure out how to make this hot new thing work for them. Well, almost everyone.

Wireless professionals are a bit jaded when it comes to SDN. That’s because they’ve seen it already in the form of controller-based solutions. The idea that a central device can issue commands to remote access devices and control configurations easily? Airespace was doing Continue reading
