Extreme Offers 60-Day Rolling Financing on Networking Products
Short-term subscription financing has been available for networking software, but it’s more rare for networking hardware.
The platform integrates with public and private cloud providers, and allows DevOps teams to deploy applications in minutes.
CA Technologies says containers are “no-brainers” because they improve flexibility and increase developer productivity.
After completing its merger with Elfiq Networks, Martello launched an SD-WAN and is putting its scalability to the test with Canada’s Center of Excellence in Next-Generation Networks.
Containers can help enterprises maximize their cloud infrastructure if deployed correctly or cause headaches if treated like more traditional VM infrastructure.
We all know that ‘lock in’ is inevitable. You make a choice and then you live with the consequences of what you have bought. However, I see a number of area where vendors are actively promoting lockin to capture unearned profits and control their partners. These dark patterns are not always obvious and I wanted […]
I woke up on Black Friday last year to a barrage of emails from users reporting 503 errors from the ipdata API.
Our users typically call our API on each page request on their websites to geolocate their users and localize their content. So this particular failure was directly impacting our users’ websites on the biggest sales day of the year.
I only lost one user that day but I came close to losing many more.
This sequence of events and their inexplicable nature — cpu, mem and i/o were nowhere near capacity. As well as concerns on how well (if at all) we would scale, given our outage, were a big wake up call to rethink our existing infrastructure.

Flow smoothing
The traffic generator in this example creates an alternating pattern: 1.25Mbytes/second for 30 seconds followed by a pause of 30 seconds. Smoothing time constants between 1 second and 500 seconds have been applied to generate the family of charts. The blue line is the result of 1 second smoothing and closely tracks the traffic pattern. At the other extreme, the dark red line is the result of 500 second smoothing, showing a constant 625Kbytes/second (the average of the waveform).
There is a tradeoff between responsiveness and variability (noise) when selecting the level of smoothing. Selecting a suitable smoothing level depends on the flow analytics application.
Low smoothing values are appropriate when fast response is required, for example:
- DDoS detection
- Leaf and spine traffic engineering using segment routing and SDN
- Internet router using merchant silicon
- Real-time traffic visualization using Netflix Vizceral
- Real-time web analytics
- Real-time visibility and control of campus networks

Deadline TODAY (23:59 UTC) to submit comments to ICANN on 2018 DNSSEC Root KSK Rollover Plan
Do you believe ICANN should go ahead with the plan to roll the Root Key Signing Key (KSK) on 11 October 2018? If so (or if not), the deadline for public comment is TODAY, 2 April 2018, at 23:59 UTC. That’s about 9.5 hours from the time I’m publishing this post.
My colleague Kevin Meynell provided more info about this public comment process when it began in March. At the IETF 101 meeting in London, I spoke with ICANN staff who again stated that they would like to hear from many voices about whether they should go ahead with the Root KSK Rollover on 11 October 2018. It’s very simple to send in comments:
You can see the current list of comments at: https://mm.icann.org/pipermail/comments-ksk-rollover-restart-01feb18/2018q1/thread.html (All comments are public.)
I would encourage anyone interested to submit comments (even if they are simply “I support the plan.”).
And if you have want more information about how to get started with using DNSSEC, please see our Deploy360 Start page to begin.

The Week in Internet News: IT Pros Know IoT Security Needs Work, But They Aren’t There Yet
What IoT security problem? Most IT professionals realize the Internet of things poses some security risks, but less than a third of them actively monitor for third-party IoT security problems, according to a survey detailed at ZDNet. More than a third of those surveyed said that nobody in their organization is responsible for reviewing the risk-management policies of their IoT vendors.
Some security risks, only faster: Meanwhile, the European Union Agency for Network and Information Security is warning organizations that 5G mobile service may bring the same security risks as earlier mobile standards have. Known flaws in SS7 and Diameter, the signaling protocols used in 2G, 3G, and 4G, could end up in 5G, and allow traffic to be eavesdropped or spoofed, reports ARN.
Community broadband for net neutrality: The American Civil Liberties Union is urging U.S. cities to build their own broadband networks as a way to protect net neutrality principles, now that the Federal Communications Commission has repealed its related regulations. The Hill has a story. Many small U.S. cities are already building their own, in an effort to provide faster or cheaper service than commercial providers, Governing Magazine says.

The Future is Containerized
Last week I announced my departure from VMware, and my intention to step away from VMware’s products and platforms to focus on a new technology area moving forward. Today marks the “official” start of a journey that’s been building for a couple years, a journey that will take me into a future that’s containerized. That journey starts in Seattle, Washington.
Why Seattle, Washington? Because that’s where Heptio is based, and because today I am joining Heptio as a senior member of the field engineering team to help drive the adoption of Kubernetes across the industry. Only a couple of folks guessed that I was headed to Heptio. If you were one of those folks, you guessed correctly!
Two questions are probably rolling around in your head right now:
- Why Kubernetes?
- Why Heptio?
Good questions!
It’s clear to me that containers will have a significant impact on how we as IT professionals will develop, deploy, upgrade, and manage applications. It’s also clear to me that when it comes to orchestrating containers, Kubernetes is the clear leader. So, if I accept that containers are going to be a significant part of IT moving forward, then it logically follows that Kubernetes is Continue reading

Why the crypto-backdoor side is morally corrupt
Crypto-backdoors for law enforcement is a reasonable position, but the side that argues for it adds things that are either outright lies or morally corrupt. Every year, the amount of digital evidence law enforcement has to solve crimes increases, yet they outrageously lie, claiming they are "going dark", losing access to evidence. A weirder claim is that those who oppose crypto-backdoors are nonetheless ethically required to make them work. This is morally corrupt.That's the point of this Lawfare post, which claims:
What I am saying is that those arguing that we should reject third-party access out of hand haven’t carried their research burden. ... There are two reasons why I think there hasn’t been enough research to establish the no-third-party access position. First, research in this area is “taboo” among security researchers. ... the second reason why I believe more research needs to be done: the fact that prominent non-government experts are publicly willing to try to build secure third-party-access solutions should make the information-security community question the consensus view.
This is nonsense. It's like claiming we haven't cured the common cold because researchers haven't spent enough effort at it. When researchers claim they've tried 10,000 ways to make Continue reading
