Pica8 makes it first steps into network automation in a unique fashion with apps for its PicOS NOS. PicaFabric build a virtual switch chassis from an leaf/spine switch clister. The PicaPilot app builds vitual switch stack for fat tree L2 everywhere campus networks. All this is done with open hardware that you can mix & […]

Central Asia, the most remote landlocked mountainous region in the world, has some of the most expensive Internet in global comparison. The cost of it can easily reach 10-20% of average monthly salary. In absolute terms, the price of the Internet can reach triple digits for 1 Mbps.
Acknowledging such challenges and considering the benefits that the Internet can bring, Central Asian governments are embarking on national digitalization strategies. The Kyrgyz Republic has launched a national program on digital transformation “Taza Koom” (“Transparent Society”). The program focuses on building an open government and a digital economy.
When it comes to digital development strategies, cooperation among countries is a mutually beneficial approach. To foster such collaboration, Cambridge University initiated a common platform called Digital Dialogue for Central Asia. The first meeting of this platform Making Inroads into Digital Transformation took place in Astana in April 2018.
Speaking at the forum on behalf of the Internet Society’s Kyrgyz Chapter, I proposed to jointly build the Digital Silk Road guided by the slogan: “free movement of ideas, people, creativity, technology and innovation”. Central Asia, with its favourable geographical location in Eurasia, could become the connecting host and focal point – a Continue reading
Networking engineers familiar with Junos love to tell me how easy it is to configure and operate IBGP EVPN overlay on top of EBGP IP underlay. Krzysztof Szarkowicz was kind enough to send me the (probably) simplest possible configuration (here’s another one by Alexander Grigorenko)
To learn more about EVPN technology and its use in data center fabrics, watch the EVPN Technical Deep Dive webinar.

(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site, or from the WWW 2018 proceedings page).
Today’s paper is all about password management for password protected web sites / applications. Even if we assume that passwords are salted and hashed in accordance with best practice (NIST’s June 2017 digital identity guidelines now mandate the use of keyed one-way functions such as CMAC), an adversary that can obtain a copy of the back-end database containing the per-user salts and the hash values can still mount brute force guessing attacks against individual passwords.
SafeKeeper goes a lot further in its protection of passwords. What really stands out is the threat model. SafeKeeper keeps end user passwords safe even when we assume that an adversary has unrestricted access to the password database. Not only that, the adversary is able to modify the content sent to the user from the web site (including active content such as client-side scripts). And not only that! The adversary is also able to read all Continue reading
Many of the groups working on edge computing are associated with telco networking. But edge computing is definitely not limited to telco networks.
With more and more platforms taking the necessary precautions against DDoS attacks like integrating DDoS mitigation services and increasing bandwidth at weak points, Layer 3 and 4 attacks are just not as effective anymore. For Cloudflare, we have fully automated Layer 3/4 based protections with our internal platform, Gatebot. In the last 6 months we have seen a large upward trend of Layer 7 based DDoS attacks. The key difference to these attacks is they are no longer focused on using huge payloads (volumetric attacks), but based on Requests per Second to exhaust server resources (CPU, Disk and Memory). On a regular basis we see attacks that are over 1 million requests per second. The graph below shows the number of Layer 7 attacks Cloudflare has monitored, which is trending up. On average seeing around 160 attacks a day, with some days spiking up to over 1000 attacks.
A year ago, Cloudflare released Rate Limiting and it is proving to be a hugely effective tool for customers to protect their web applications and APIs from all sorts of attacks, from “low and slow” DDoS attacks, through to bot-based attacks, such as credential stuffing and content scraping. We’re pleased about the Continue reading
“Death and taxes” is a phrase that is usually attributed to Benjamin Franklin from a quote in a 1789 letter: “In this world nothing can be said to be certain, except death and taxes.” Public cloud computing providers didn’t exist back in the days of Franklin, but if they did, they would have no doubt made the list. Here’s why. Public clouds for large data analysis, just like death and taxes, are clearly inevitable because of two things. One simple and now rather worn out cliché. That would be scale and the slightly more subtle data.
Nation states are racing …
The Inevitability Of Death, Taxes, And Clouds was written by James Cuff at The Next Platform.
Operators are moving aggressively to tighten their use of OpenStack and Kubernetes to bolster cloud deployments.
While the network engineering world tends to use the word resilience to describe a system that will support rapid change in the real world, another word often used in computer science is robustness. What makes a system robust or resilient? If you ask a network engineer this question, the most likely answer you will get is something like there is no single point of failure. This common answer, however, does not go “far enough” in describing resilience. For instance, it is at least sometimes the case that adding more redundancy into a network can actually harm MTTR. A simple example: adding more links in parallel can cause the control plane to converge more slowly; at some point, the time to converge can be reduced enough to offset the higher path availability.
In other cases, automating the response to a change in the network can harm MTTR. For instance, we often nail a static route up and redistribute that, rather than redistributing live routing information between protocols. Experience shows that sometimes not reacting automatically is better than reacting automatically.
This post will look at a paper that examines robustness more deeply, Robustness in Complexity Systems,” by Steven Gribble. While this Continue reading
The small cell platform supports interface splits between the central unit and the remote radio head, which means operators can use it for fronthaul.
The startup’s technology aims to make digital assistants and bots sound more human.
