It is my privilege to return as a delegate for Network Field Day 11 in Silicon Valley on January 20-22. You can find full details on the event at Tech Field Day page which lists the vendors and delegates in full. Lots of familiar faces and a few new ones.

Chapter by chapter Sergey Ignatchenko is putting together a wonderful book on the Development and Deployment of Massively Multiplayer Games, though it has much broader applicability than games. Here's a recent chapter from his book.

Hamlet:
Thou art as sweet as the sum of the sum of Romeo and his horse and his black cat! Speak thy mind!

Our Classical Deployment Architecture (especially if you do use FSMs) is not bad, and it will work, but there is still quite a bit of room for improvement for most of the games out there. More specifically, we can add another row of servers in front of the Game Servers, as shown on Fig VI.8:
A public cloud is excellent for running ephemeral NFV labs.
Among all the skills I hear network engineers talk about, two that are often underrated are writing skills and graphics skills. There is some small slice of the networking world that is serious about writing (though I often think we make too big of a production out of writing, getting wrapped around tools and process instead of focusing on actual writing), but graphics is one area the we really don’t talk about a lot. After all, I’m an engineer, not a graphic designer, right? Or maybe — I’ve always heard I should be a master of one skill, rather than a jack of all trades…
Diane, over at Data Center Mix, has a great post up on four ways being an artist has helped her sell data center products. There are some great ideas in there, but as someone with formal training in graphic design (in a distant past I can barely remember any longer), I wanted to add a few thoughts about graphics skills as a network engineer.
She begins with this thought: a picture is worth a thousand words. I’m never quite certain this is actually true in every case (Charles Dickens in cartoon format doesn’t sound very Continue reading
For the purpose of high availability, critical locations of company A – a customer of VPN service provider – is connected to two different carriers. However, this connectivity requires an important design consideration. Figure-1 In the network design shown above, customer AS 64512 is connected to two different providers: AS100 and AS200. Since this site is critical to the […]

Flooding in full-mesh topology is a big concern for network-design experts, especially in large-scale OSPF deployments. When the link or node fails in an OSPF network, failure information is flooded everywhere in the same area. If Flat OSPF network design is used, then the problem gets bigger. Each router receives at least one copy of the new information from […]

Network Change Nothing sparks engineering debate quite as much as ‘network change control’. It’s one of those topics we love to hate. We feel buried by useless bureaucracy. We ask, ‘Why can’t our managers just trust us, instead of weighing us … Continue reading

How does Path MTU Discovery (PMTUD) work ?
Almost six years ago I shared my (then) current Getting Things Done (GTD) setup, in which I described how I used various tools, techniques, and applications to try to maximize my productivity. I’d been toying with updating that post, but I wasn’t sure that anyone would find it useful. However, a recent e-mail from a reader indicated that there probably is some interest; with that in mind, then, here’s an update on my GTD-like setup, circa early 2016.
Before I dive into the details, a couple quick notes:
If you read the 2010 post, you may recall that I think of my workflow as having three “layers” of applications:
I’m proud to be the owner of the best computer network design blog and get positive feedbacks from users all over the world. In recent times, I have observed that everybody has been reading this blog. Because of this, I owe all the readers of this blog my achievements. Indeed, your comments and post views have encouraged […]
