Junos – Wildcard Ranges, Interface Ranges and Configuration Groups
Until recently I have worked almost exclusively on Cisco ASA and IOS platforms. Within the last six months I’ve added Juniper’s Junos platform into my repertoire.

HTIRW: Provider Peering and Revenue Streams (Part 1)
In the last post in this series, I described several types of providers — and even how those descriptions are no longer really “pure,” for the most part (although NTT, for instance, is a pure transit provider that only offers a few services throughout the world). For each piece of a provider’s business, then — […]

Automating the Cabbage Patch Network Today (2014)
“Sometimes my head is a bit of an idiot” is something my daughter might say and that happens to me too, if that time is today and this article, let me know. If you don’t get the Cabbage Patch reference and its juxtaposition to automation, see here. I’ve tried to avoid sarcasm (and arrogance) but have […]

Thinking Through Title II Reguation
Over at CircleID, Geoff Huston has a long’ish article on Title II regulation of the Internet, and the ideals of “net neutrality.” The reasoning is tight and strong — his conclusion a simple one: At its heart, the Internet access business really is a common carrier business. So my advice to the FCC is to […]

PQ Show 34 – Cloudflare Keyless SSL
A couple of weeks ago, Cloudflare announced a new solution that allows DDOS Protection, Caching and application firewalls of SSL encrypted traffic without handing over the private key. This is a significant breakthrough for companies. Many companies have strong controls over private keys that prevent external sharing. More often the simple cost of key ceremonies is punitive to the business.

Now that We’ve Buried the Seven Layer Model…
“But the seven layer model is still useful for teaching networking…” So ran the most common reaction to my post last week about the seven layer model being dead. But let me ask something — how useful is the seven layer model for teaching networking? It doesn’t match the TCP/IP stack, it doesn’t account for […]

Traveling Light – 15 Things in an Engineer’s Bag (including the bag)
My day job involves traveling around northern Europe and occasionally further afield. I often get little notice of where I’m going, or how long I’m going for. This makes for a lot of trudging along train platforms and across departure lounges. Hauling too much stuff around is guaranteed to ruin my day. Traveling light becomes a necessity, […]

What The Heck Is SPDY?
A10‘s presentation at NFD8 seemed to generate a bit of interest (dare I say excitement) and many a question around the SPDY (pronounced ‘speedy’) protocol. I promised Lindsey Hill (@northlandboy) on Twitter that I’d write a blog post about it and here it is. It took me rather longer to write than I thought and […]

If you watch the software defined networking space, you might have noticed that Brocade has been quietly hiring a sharp group of actual (not self-proclaimed) thought leaders and developers.

The Seven Layer Model is Dead
Whether we have the funeral in New Orleans style (with a lot of brass and, well, other stuff), or in the more somber style we’re all so accustomed to– or even perhaps dance down the road singing, “ding dong, the model’s dead” — it’s time to pack the seven layer model into a virtual coffin […]

PQ Show 33 – Intel Rack Scale Architecture – Real or Impractical ?
At the IDF 2014 conference, Intel made a big song and dance about their Rack Scale Architecture which removes the need for “top of rack” networking and changes the nature of servers in a big way. My initial impression is that this has limited application in the enterprise or cloud providers but might be useful […]
