How Did SDN Change from Incumbent-Free to Incumbent-Lock-In?

About 10 years ago, a few smart folks invented “Software Defined Networking” or SDN for short.  SDN promised to “separate the data plane from the control plane”, but another objective was to break free from vendor lock-in. They wanted SDN to enable a network where one can design the network, manage it and monitor it […]

On Segment(ed) Routing

Traffic Engineering On Segment(ed) Routing Using MPLS and IPv6 Segment Routing is one of the hottest technologies being considered to transform the way packets are handled in critical networking infrastructures. Whether it is in the core of the internet, within data centers, or between data centers, Segment Routing is seen as a simpler way to […]

Best DPU based SmartNICs for Building the Smart Cloud: PART I

The Best SmartNIC for the Cloud Enables software-defined, hardware-accelerated networking for a high performance SmartNIC with programmable flexibility

The Smart Cloud is here and it needs the Best Smart NICs Amazon recently announced that Alexa, the smart personal voice assistant is coming out of a small desktop gadget (pick your flavor: echo dot, spot, hub, show, etc.) and getting into the very fabric of our life. Anything and everything is getting an Alexa boost […]

What Is a SmartNIC

Everyone is talking about DPUs (Data Processing Unit) based SmartNIC but without ever answering one simple question: what is a “SmartNIC ” and what do they do? Now a NIC of course stands for a “Network Interface Card”; practically speaking a NIC is a PCIe card that plugs into server or storage box to enable […]

Foreshadowing the Future of Security Meltdowns and the Spectre of a Breach

Foreshadow CPU vulnerability threatens host-based security model

Here we go again… Only 8 months after the Spectre and Meltdown CPU vulnerabilities were disclosed, researchers have published Foreshadow, another related attack vector that exploits “Speculative Execution”. This one goes after the “SGX” (Software Guard Extensions) secure enclave feature built into newer Intel processors since the Skylake series. This is very serious, as it […]

Seven Predictions for 2017

As we look forward to 2017 it is time to peer out into the distance and think about what will happen during the year:   2017 will mark the beginning of the Hunger Games for high performance Optical Component Startups. This fight to the death battle is inevitable, because there is no de-facto industry standard […]

How to Get 100G Performance Out of Your 100GbE SDN

The high bandwidth requirements of modern data centers are driven by the demands of business applications, data explosion, and the much faster storage devices available today. For example, to utilize a 100GbE link, you needed 250 hard drives in the past, while today, you need only three NVMe SSDs. After investing in the most advanced […]

Fighting Distributed Attacks (DDoS) with Distributed Defense

Part 1: The DDoS Threat and Changing Landscape of Protection Distributed Denial of Service (DDoS) attacks have been around for quite a while and their profile was raised again last month when Dyn Inc., one of the largest DNS provider sites, was hit with a very large scale (tens of millions of zombie agents) attack […]

Mellanox Takes Supercomputing16 by Storm

Although activities have been going on for a few days now, Supercomputing 16 officially opened last night in chilly Salt Lake City, Utah with Mellanox Technologies leading the charge. I’ll be bringing you updates throughout the week starting with today’s milestones and several key announcements. Today’s highlights include: Big news from the TOP500 Supercomputers list […]

Tough Choices No More, at Least for SDN

It is great to have choices, but making decisions is hard, especially when none of the choices seems perfect; they all have their pros and cons. As the 2016 presidential election time draws near, many Americans are reminded of tough decision making that comes as part of the political freedom and democracy. And across the […]
