EVPN – the basics


So I decided to take a deep dive into eVPN, I’ll mostly be looking into VLAN-aware bundling, as per RFC 7432 – and mostly because I think this will fit more closely, with the types of deployments most of the customers are used to – good old IRB interfaces and bridge-tables!

As everyone knows, VPLS has been available for many years now and it’s pretty widely deployed, most of the customers I see have some flavour of VPLS configured on their networks and use it to good effect – so why eVPN? what’s the point in introducing a new technology if the current one appears to work fine.

The reality is that multipoint layer-2 VPNs (VPLS) were never quite as polished as layer-3 VPNs, when layer-3 VPNs were first invented they became, and still are the in many cases the “go to” technology for layer-3 connectivity across MPLS networks, and…

Tile Tracking with Lego Minifig shown to scale

Tile Bluetooth Tracker – Quick Review

I recently stumbled on a clutch of Tile Bluetooth trackers in an airport departure lounge. I’d just disappeared down a Bluetooth LE devices security rabbit hole and was using the RamBLE app to discover what was about (who knew there were so many Samsung Smart TVs around?). I’ve been aware of the Tile and it’s companion app  for a while. As they didn’t work with Android until recently, I had resisted purchase. With a imminent family holiday to a large European theme park with a child with a history of legging it; I purchased a pack of four Tiles for £50.

Jabra SPEAK 510 Speakerphone – Quick Review

I spend quite a lot of time on conference calls, often at short notice and without prior clue was to what I will be talking about. I’ve been using my laptop as a speakerphone for a while, but I miss physical buttons. I looked at SOHO VOIP phones, as l like the idea of an old-fashioned handset. However, with limited desktop space for they seemed a cumbersome extravagance. Most of the SOHO handsets are Android based and include some level of Skype integration, but I just couldn’t find exactly what I wanted. Continue reading

Dell UP2414Q vs P2415Q 4K Monitors – Very quick review

In a fit of optimism, and pique over my UP2414Q turning itself off a dozen times a day I bought a Dell P2415Q to either replace and/or supplement my first generation 4K monitor. On paper, the specification of the two monitors is virtually identical,but in the flesh; they are perceivably different.

IKEA BEKANT Standing Desk Review – 1 Month in

For most of my professional life I have sat on my arse, staring at a screen. You get to thirty something and start worrying about the long-term health drawbacks of a such a sedentary lifestyle. Spurned on by a home-office move and ongoing back grumbles I bought myself an IKEA BEKANT standing desk. You can easily spend a fortune on these things, however I’m unashamed to have made more than a few “tactical” Ikea furniture purchases. It’s built to a precise price point, if you are happy with that definition of value then it’s been generally been acceptable.

802.11ac Is A Big Fat Pack of Lies


We’ve been hoodwinked. They snookered us. The wool has done been pulled over our eyes. Ah yes, the snake oil convention came to town, and we all went in the big tent and bought us some. But who could blame us for getting all sparkly-eyed when you breathe in the aroma of those fat numbers promised by 802.11ac? It’s intoxicating stuff, this getting-ever-faster Wi-Fi. But alas… it’s also fraudulent promises, broken hearts, and “Ha! Made you look!” all put in a shit sandwich that we’re willingly nibbling on.

OK- so maybe it’s not quite that bad. But it’s safe to say that with 802.11ac, and even 802.11n, the standards-authors are writing certain checks that the Bank of Reality just can’t cash, despite the giddy marketing folks’ best efforts to convince us otherwise.

Have I bummed you out yet? You might be wondering what could put an upbeat, good-looking fella like myself in this sort…
