Increased programmability brings more options to networks

Options. Everyone needs options. Whenever I travel somewhere with my wife, Christine, even if it’s for a weekend, she needs to check a bag. When I ask her why, she says, “A girl needs options,” hence the oversize luggage.While it’s been easy for someone like my wife to have options, network engineers have never really had the same luxury. Network switches were typically built with fixed functionality, so an organization would need to purchase a wide range of equipment to meet all their needs. Network professionals need greater flexibility from the network Recently, the chip manufacturers have been building more programmable, flexible products. One of the examples of this is the Cavium XPliant processor that is the silicon that powers Arista’s 7160 switch. Another example is the Barefoot Networks Tofino processor. In addition to being one of the most scenic places on the planet, Tofino is a powerful system on a chip with a fully programmable parser and pipeline. The chip supports 256x 25 Gig-E Serializer/Deserializer (SerDes) at speeds of 1, 10, 25, 40, 50, and 100 Gig-E.To read this article in full, please click here

BMC retools its service management offerings for AI, cloud era

Many if not most large enterprises run hybrid computing environments and are looking for management software flexible enough to run in and manage assets across private and public clouds.Against this backdrop, BMC has rebuilt its venerable IT service-management product suite to run on a range of cloud platforms while incorporating machine learning to enhance predictive-analysis capabilities.[ Now see who's developing quantum computers.] The BMC Helix Cognitive Service Management is a software-as-a-service (SaaS) offering that runs on Amazon Web Services as well as BMC's own cloud. It will be available for Azure in the fourth quarter and for Google Public Cloud at the end of the year or beginning of next year, BMC said.To read this article in full, please click here

Universal Cloud Networking with Arista 7170

There is a shift happening in the world of Artificial Intelligence requiring a new breed of servers, storage and cloud networks. Artificial intelligence applications for patterns, photos and speech recognition have driven a processor evolution from CPUs to NPUs to now, GPUs. Networking is witnessing a parallel evolution and pushing the scale of shuttling massive data between machines. It creates an ever-increasing need for control over the way networks are rebuilt. Building these networks requires both, programmable paths to drive intelligence and uncompromised performance. Doing both hasn’t been easy until now.

What happens if IoT security doesn’t get solved?

Sometimes, confirmation of the obvious can be really important. At least, that’s how I felt when I saw a new Bain & Company report, Cybersecurity Is the Key to Unlocking Demand in IoT. According to the consulting firm’s survey, 45 percent of Internet of Things (IoT) buyers say “concerns about security remain a significant barrier and are hindering the adoption of IoT devices.” Worries over IoT security are hardly news, of course. I’ve been writing about them here on Network World for a while, and a quick internet search for IoT security rains down more than a million hits.To read this article in full, please click here

SDNs and NFV are complementary and core components of modernized networks

The terms software defined networking (SDN) and network functions virtualization (NFV) are often used interchangeably, which is incorrect.  In a sense, the two are tied together as companies start using NFV as part of their SDN plans but that doesn’t have to be the case.Enterprises could maintain their current network architecture and shift to NFV or they could roll out an SDN and never leverage the benefits of NFV, so it’s important to understand what each is and the benefits of both.[ For more on SDN see where SDN is going and learn the difference between SDN and NFV. | Get regularly scheduled insights by signing up for Network World newsletters. ] What is software-defined Networking SDNs are a fundamentally different way to think about networks.  Technically, SDNs can be defined as the separation of the management, control and data-forwarding planes of networks.  Many people, including technical individuals read that definition and say, “So what?”, but the separation of these planes has a profound impact on networks and enables things that have never been done before.To read this article in full, please click here

Integrating 3rd Party Firewalls with Amazon Web Services (AWS) VPC Networking

After figuring out how packet forwarding really works within AWS VPC (here’s an overview, the slide deck is already available to ipSpace.net subscribers) the next obvious question should be: “and how do I integrate a network services device like a next-generation firewall I have to use because $securityPolicy into that environment?”

Please don’t get me started on whether that makes sense, that’s a different discussion.

Christer Swartz, an old-time CCIE and occasional guest on Software Gone Wild podcast will show you how to do it with a Palo Alto firewall during my Amazon Web Services Networking Deep Dive workshop on June 13^th in Zurich, Switzerland (register here).

An Update for my Adoring Fans

I feel like a teenage girl with a fashion blog who hasn’t posted in 6 months and comes back with “I know I haven’t posted in a while…”  Sigh.  It’s been right at a year since I actually published a post, so I figured I would give everyone an update.

I’ve had some personal things going on lately, and those have taken all of my energy.  We’ve made it through those rough times, so my energy is coming back.  I’m feeling better every day, and I hope I can get back to producing some content.  And, let me tell you…I’ve got some stuff to talk about.

*insert star wipe here*

We got a new director-level dude at the office, and he’s really mixing things up for us.  His philosophy includes changing the way we do everything that we do.  Like literally everything.  He ran a report for me on my ticket queue and showed me that 60% of my ticket count was on stupid stuff that’s below my pay grade.  His advice : Make somebody else do it.  So I did.  I taught myself some more Python (not hard since Continue reading
