Everyone’s talking about 5G. Industries as diverse as healthcare, agriculture, automotive, broadcast, utilities and public safety – to name but a few – have all been strategizing how they can use the new connectivity standard to drive efficiencies, improve business and enhance the end-user experience. There is a need to define and trial use cases […]
Evaluate and characterize the performance of a virtual network before a huge NFVi roll out. Test with TestCenter Virtual and Attero-V. Growing needs of virtualizing an infrastructure to cater paradigms of NFV (Network Function Virtualization) calls for divergent test methods. Data Center administrators and service providers are becoming very interested in evaluating and characterizing the […]
A fundamental building block for 5G networks is coming in the form of mmWave technology, which will enable key aspects of future autonomous vehicles. 5G will give a big boost to self-driving autonomous vehicles. Intel goes so far as to say that 5G is like oxygen for autonomous vehicles. Really? Yes, I have to agree. […]
Centralized Radio Access Network (C-RAN) deployment is a growing trend in the wireless industry. I am often asked what is driving this trend, why some operators are using it more than others, and what are some of the challenges and benefits of C-RAN. In this blog, I will try to capture some of those questions […]

On-Demand ADM On-demand ADM offers fast discovery of application interdependencies, building maps that visualize these complex relationships with simple […]
The Tolly Group reveals key performance benchmarks as high-speed networks underscore need for greater integrity in network monitoring. In today’s networks where 40 Gb links are becoming more and more common, simply “capturing” network data is half the battle. It must also be effectively analyzed to provide actionable insights. The caveat is that network performance monitoring insights […]
An external network pentest without thorough open source intelligence gathering is just a glorified vulnerability scan. I did an external network pentest for a client a few weeks back that led to some decent pwnage, and as if writing the report wasn’t tiring enough, I decided to do a blog post as well. Go figure. […]
Another day, another cyberattack. Just as companies were recovering after the WannaCry attack, a number of organizations were hit by Petya… or NotPetya. Name it as you see fit. In a matter of just two months, two devastating ransomware attacks have crippled networks globally. Clearly, security threats are multiplying in intensity and complexity. But what […]
