IDG Contributor Network: It’s time for SD-WAN to grow up

2018 has already been hailed as the “Year of SD-WAN” and while the promises of this technology are undoubtedly appealing to most enterprises, it’s equally important to understand its potential shortcomings.The “Death of the Router” has been largely exaggerated by those trying to market their “silver bullet” solutions that still lack basic routing capabilities. While there’s no doubt that years of technical debt have added some unnecessary functionality to the modern router, it’s worth acknowledging that there are many “table-stakes” features leveraged that need to exist in any SD-WAN solution that is meant to replace those boring routers.I’d like to highlight some often-missed considerations drawn from hard lessons learned by SD-WAN early adopters. Specific names and details have been left out to protect both the guilty and innocent.To read this article in full, please click here

The Larger Facebook/Cambridge Analytica Question: Is this really what we signed up for?

Mark Zuckerburg’s testimony before the US Congress today and the flood of news about the privacy breach at Facebook and revelations that the company mishandled the data of millions of people has me asking:

Is this really what we signed up for?

It is clear that we are not in control of our online information nor do we really have any idea how it is bought, sold, or used.

For some of us, signing up for a social network like Facebook was about staying in touch with our kids and friends. For others, it was an easy way to reach new customers, or gather a community behind a social project. Yes, many of us figured out that our information was being used to serve up ‘relevant’ ads: as a matter of fact, that seems pretty standard in today’s online world. But that’s only a small part of a much bigger picture.

In the past few weeks we have found out – yet again – that information about ourselves, and our friends and contacts was used far beyond what we intended. We have been profiled, pigeon-holed, politically manipulated, and played like pawns in someone else’s chess game. I’d challenge you to Continue reading

New in IPv6: The Next Chapter in IPv6 Multihoming Saga

Remember the IPv6 elephant in the room – the inability to do small-site multihoming without NAT (well, NPT66)? IPv6 is old enough to buy its own beer, but the elephant is still hogging the room. Tons of ideas have been thrown around in IETF (mostly based on source address selection tricks), but none of that spaghetti stuck to the wall.

MPLS 101 – MPLS VPNs

In our last post, we removed our last piece of static configuration and replaced static routes with BGP.  We’re going to pick up right where we left off and discuss another use case for MPLS – MPLS VPNs.  Really – we’re talking about two different things here.  The first is BGP VPNv4 address families used for route advertisement.  The second is using MPLS as a data plane to reach the prefixes being announced by VPNv4 address family.  If that doesn’t make sense yet – don’t worry – it will be pretty clear by the end of the post.  So as usual – let’s jump right into this and talk about our lab setup.

As I mentioned in the last post, setting up BGP was a prerequisite to this post – so since that’s the case – Im going to pick up right where I left off.  So I’ll post the lab topology picture here for the sake of posting a lab topology – but if you want to get your configuration prepped – take a look at the last post.  At the end of the last post we had our Continue reading

NetDevOpEd: Automation – start small, dream big

I’ve seen a number of blogs and articles describing what network automation is and what it entails, and in many cases, the descriptions end up frightening people who haven’t yet started down an automation path. The biggest question when starting any of these sorts of projects is the simplest: should you automate at all?

My answer to that first question (Spoiler alert: it’s yes, but let me explain why) is that it depends on your network itself. For years, before I was involved with networking at the operating system level, I worked on network management and automation products. Often, I’d tell my customers that if they were happy with the status quo, then I certainly wouldn’t force them down a particular path or to use a particular product. However, if you’re a bit fed up with the manual steps involved in updating a device operating system or configuring a device, then you should look into automation to save yourself time and headaches. Of course, if you only have three devices and they get updated yearly, maybe don’t bother. But if you believe automation will provide the solutions you’re looking for, there are some first steps for automation that you Continue reading

Is the cloud already killing the enterprise data center?

“Friends don't let friends build data centers.”That slogan wasn’t even printed on a real T-shirt you could buy. It was just one of the choices in an online poll to choose what Amazon Web Services CTO Werner Vogels should wear. But it pretty much captured the mood at the AWS Summit San Francisco last week, where Vogels gave the opening keynote to some 9,000 cloud-loving attendees. On stage, Vogels crowed about multiple enterprises abandoning large numbers of data centers in order to move their workloads to the cloud. He cited Cox Automotive—the company behind Autotrader, Dealer.com, Kelley Blue Book, and many more car-shopping brands—“going all in on AWS” and closing more than 40 data centers. He noted that U.K. news provider News International is shutting down 60 data centers, and GE is closing approximately 30 data centers. And Vogels mentioned that the U.K.’s Ministry of Justice was moving to AWS, as well, though he didn’t say whether it was closing any data centers in the process.To read this article in full, please click here

IDG Contributor Network: Closing the PC/TC experience gap for good

When thin clients were first introduced to the market in 1995, there was a cultural backlash. Thin clients may have made working with company data less costly and more secure, but from the workers’ perspective, their PC was replaced by a little box connected by a serial cable, with limited graphics that was much slower than the PC they were used to working on every day.In those early days, even as we swapped the serial cables for network ones, shrunk the cases, and doubled the performance, it didn’t take long before thin clients were banished to niche use cases, becoming the territory of call centers, nurses’ stations and manufacturing plants—often to those workers’ disappointment.To read this article in full, please click here
