SD-WAN Vendor Landscape

In the Three Paths of Enterprise IT part of Business Aspects of Networking webinar I covered the traditional networking vendor landscape. Let’s try to do the same for SD-WAN.

It’s clear that we have two types of SD-WAN vendors:

Vega-Lite: a grammar of interactive graphics

Vega-lite: a grammar of interactive graphics Satyanarayan et al., IEEE transactions on visualization and computer graphics, 2016

From time to time I receive a request for more HCI (human-computer interaction) related papers in The Morning Paper. If you’ve been a follower of The Morning Paper for any time at all you can probably tell that I naturally gravitate more towards the feeds-and-speeds end of the spectrum than user experience and interaction design. But what good is a super-fast system that nobody uses! With the help of Aditya Parameswaran, who recently received a VLDB Early Career Research Contribution Award for his work on the development of tools for large-scale data exploration targeting non-programmers, I’ve chosen a selection of data exploration, visualisation and interaction papers for this week. Thank you Aditya! Fingers crossed I’ll be able to bring you more from Aditya Parameswaran in future editions.

Vega and Vega-lite follow in a long line of work that can trace its roots back to Wilkinson’s ‘The Grammar of Graphics.’ It’s all the way back to 2015 since we last looked at the Vega-family on The Morning Paper (see ‘Declarative interaction design for data visualization’ and ‘[Reactive Continue reading

Tokalabs Software Defined Labs automates configuration of lab test-beds

Network environments have become so complex that companies such as systems integrators, equipment manufacturers and enterprise organizations feel compelled to test their configurations and equipment in lab environments before deployment. Performance test labs are used extensively for quality, proof of concept, customer support, and technical sales initiatives. Labs are the perfect place to see how well something performs before it’s put into a production environment.The primary challenge of running a test lab is the amount of time it takes to provision the test environments. A network lab infrastructure might include switches, routers, servers, virtual machines running on various server clusters, security services, cloud resources, software and so on. It takes considerable time to wire the configurations, physically build the desired test beds, login to each individual device and load the proper software configurations. Quite often, lab staffers spend more time on setup than they do on conducting actual tests.To read this article in full, please click here

Spousetivities in Barcelona at VMworld EMEA 2019

Barcelona is probably my favorite city in Europe—which works out well, since VMware seems to have settled on Barcelona at the destination for VMworld EMEA. VMworld is back in Barcelona again this year, and I’m fortunate enough to be able to attend. VMworld in Barcelona wouldn’t be the same without Spousetivities, though, and I’m happy to report that Spousetivities will be in Barcelona. In fact, registration is already open!

If you’re bringing along a spouse, significant other, boyfriend/girlfriend, or just some family members, you owe it to them to look into Spousetivities. You’ll be able to focus at the conference knowing that your loved one(s) are not only safe, but enjoying some amazing activities in and around Barcelona. Here’s a quick peek at what Crystal and her team have lined up this year:

• A wine tour of the Penedes region (southwest of Barcelona)—attendees will get to see some amazing wineries not frequented by tourists!
• A walking tour of Barcelona
• A tapas cooking class
• A fantastic walking tour of Costa Brava, Pals, and Girona
• A sailing tour (it’s a 3 hour tour, but it won’t end up like Gilligan’s)

Lunch and private transportation are included for all activities, and all activities Continue reading

MUST READ: The NTP Bible

A few months ago Johannes Weber sent me a short email saying “hey, I plan to write a few NTP posts” and I replied “well, ping me when you have something ready”.

In the meantime he wrote a veritable NTP bible - a series of NTP-related blog posts covering everything from Why Should I Run My Own NTP Servers to authentication, security and monitoring - definitely a MUST READ if you care about knowing what time it is.

Fundamentals of MPLS LSPs

One of the items that often trips folks up with MPLS is the concept of label switched paths or LSPs. We’ve talked about them extensively before in many of the blog posts here and I’ve described them a couple of different ways. Many people look at an LSP as a sort of unidirectional tunnel. In fact, most network diagrams aiming to describe an LSP often show it just as that – a tunnel. It’s an easy thing to visualize especially when you start talking about nested tunnels or LSPs inside of LSPs, but I also think it can be rather confusing. This becomes even more confusing when people start talking about end to end LSPs or how a service label is the same end to end as traffic traverses an LSP. What does that mean? Where does an LSP start or stop? Is it really a tunnel? How far can an LSP reach? What if we run different label distribution protocols? In this post, and perhaps the next, I hope to address these questions as well as talk about how we can solve some of the common problems that are often encountered with LSPs.

So let’s dive right in and Continue reading

Network pros react to new Cisco certification curriculum

Software skills are set to play a more prominent role in Cisco’s network engineering curriculum. The company is launching a new coding-focused certification track, as well as giving its existing certifications a major revamp to address software-defined networking (SDN), automation, the Internet of Things, and other emerging technologies that are changing the job requirements for today’s network professionals. "They’re not trying to turn network folks into developers, but they are certainly trying to make it easier for us to do our job," says Dan Groscost, solutions architect at Computer Design & Integration, an IT services firm based in New York, N.Y. Groscost holds a Cisco Certified Network Professional (CCNP) certification, and he’s in the final stages of his Cisco Certified Internetwork Expert (CCIE) Route/Switch certification.  To read this article in full, please click here

PostgreSQL Connection Pooling: Part 1 – Pros & Cons

A long time ago, in a galaxy far far away, ‘threads’ were a programming novelty rarely used and seldom trusted. In that environment, the first PostgreSQL developers decided forking a process for each connection to the database is the safest choice. It would be a shame if your database crashed, after all.

Since then, a lot of water has flown under that bridge, but the PostgreSQL community has stuck by their original decision. It is difficult to fault their argument – as it’s absolutely true that:

Locked Up By Lock-In

When you start evaluating a solution, you are going to get a laundry list of features and functionality that you are supposed to use as criteria for selection. Some are important, like the ones that give you the feature set you need to get your job done. Others are less important for the majority of use cases. One thing tends to stand out for me though.

Since the dawn of platforms, I believe the first piece of comparison marketing has been “avoids lock-in”. You know you’ve seen it too. For those that may not be completely familiar with the term, “lock-in” describes a platform where all the components need to come from the same manufacturer or group of manufacturers in order to work properly. An example would be if a networking solution required you to purchase routers, switches, access points, and firewalls from a single vendor in order to work properly.

Chain of Fools

Lock in is the greatest asset a platform company has. The more devices they can sell you the more money they can get from you at every turn. That’s what they want. So they’re going to do everything they can to keep you in their ecosystem. Continue reading
