NASA to use data lasers to beam data from space to Earth

Starting in 2019, NASA will begin using laser communications technology to "enable greater return of science data from space." The reason is laser is more bandwidth-friendly than classic radio for data delivery, plus it's more secure, NASA says in a newly released explainer of its plans.Laser signals from space will be much harder to hack than old-school radio because the signal is more concentrated, the agency says on its website. Plus, the higher frequencies provide more bandwidth — important for space data crunching. And laser equipment is lighter, allowing for longer missions, among other benefits.To read this article in full, please click here

Linux kernel 4.18: Better security, leaner code

The recent release of Linux kernel 4.18 followed closely by the releases of 4.18.1, 4.18.2, 4.18.3, 4.18.4, and 4.18.5 brings some important changes to the Linux landscape along with a boatload of tweaks, fixes, and improvements.While many of the more significant changes might knock the socks off developers who have been aiming at these advancements for quite some time, the bulk of them are likely to go unnoticed by the broad expanse of Linux users. Here we take a look at some of the things this new kernel brings to our systems that might just make your something-to-get-a-little-excited-about list.[ Also read: Invaluable tips and tricks for troubleshooting Linux ] Code Cleanup For one thing, the 4.18 kernel has brought about the surprising removal of nearly 100,000 lines of outdated code. That's a lot of code! Does this mean that any of your favorite features may have been ripped out? That is not very likely. This code cleanup does means that a lot of code deadwood has been carefully expunged from the kernel along with one significant chunk. As a result, the new kernel should take up less memory, Continue reading

Traditional Leaf-and-Spine Fabric Versus Cisco ACI

One of my subscribers wondered whether it would make sense to build a traditional leaf-and-spine fabric or go for Cisco ACI. He started his email with:

One option is a "standalone" Spine/Leaf VXLAN-with EVPN deployment based on Nexus equipment. This approach could probably be accompanied by some kind of automation like Ansible to ease operation/maintenance of the network.

This is what I would do these days if the customer feels comfortable investing at least the minimum amount of work into an automation solution. Having simpler technology + well-understood automation solution is (in my biased opinion) better than having a complex black box.

8 “Fake News” Items that Tried to Hold Back Open Networking

The parallels between the efforts of the various open networking communities to modernize the networking industry and a Saturday afternoon pee-wee soccer scrum are far too close for comfort.  Both are characterized by loads of noisy, colorful – and mostly circular – movement – eventually followed by exhausted players staring at a ball that seems to be sitting pretty much right where it started.

At least that’s the way it’s been playing out for all the intrepid IT stewards running large enterprise networks — until now.  After years of enduring legacy-vendor-driven “fake news” stories paired with whispered misdirection designed to hold back the disaggregated white box open networking movement as a whole, truth has – finally — won out. 

Multiple Fortune 100 companies are now deploying open white box switches running Pica8’s PICOS® network operating system in their campus and branch office networks, mostly replacing aging Cisco and Juniper architectures.  (A parallel, in a sense, to the on-going white box tsunami in the data center.) Enterprise IT teams now realize that the access edge for campus networks is fully in play for long-overdue upgrades and replacements by more modern, simpler, more flexible, and vastly more Continue reading

BrandPost: Beyond the Firewall – Different Rules for East-West Traffic

Network firewalls were created to block unauthorized content and code from the network while ensuring the unimpeded flow of data packets vital to the operations of the enterprise. But they were designed to intercept external incursion, not prevent security issues inside the network.“As server virtualization has increased in popularity, the amount of traffic moving laterally across the data center (East-West) has dwarfed traditional client-server traffic, which moves in and out (North-South),” industry analyst Zeus Kerravala writes in Network World. “This is playing havoc with data center managers as they attempt to meet the demands of this era of IT.”To read this article in full, please click here

Ideas this bad could kill the Internet of Things

What’s the silliest, dumbest, most ridiculous Internet of Things (IoT) application you can think of? Smart toothbrushes? Internet-connected toilets? Digital notepads in the shower?Well, forget all that. Heck, you can even forget the "smart" Air Dresser wardrobe that Samsung announced earlier this month. (If you’re wondering, this digital closet is said to automatically "air" — whatever that means — steam, dry, and purify clothes so they don’t, you know, stink.)IBM has just patented an IoT device concept so incredibly inane that it makes all those earlier attempts to trivialize the IoT seem like cures for cancer. What could possibly be so ill-conceived as to make a smart hairbrush look, well, smart?To read this article in full, please click here
