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 […]

Show 206 – Brocade’s OpenDaylight-Based Vyatta Controller – Sponsored
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 question has been, “To what end? What’s Brocade going to do with all of these capable folks?” Today, we can answer that question. Brocade has built an […]

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 […]

Viewing HTTP Headers Using Browser Developer Tools
I often find myself viewing HTTP headers (request and response) at the ‘client side’, which are often much quicker (and safer) than decrypting SSL/TLS traffic on a load balancer/ADC. With the use of SSL/TLS growing rapidly even within private networks and the inability to decrypt PFS/DHE protected traffic, this can often be the only way to troubleshoot. The reasons I […]
