Dissecting IBGP+EBGP Junos Configuration
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)

Rate Limiting: Delivering more rules, and greater control
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

Research: Robustness in Complex Systems
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

Global Editathon: Making Women in Tech Visible
Why is it necessary to “edit” the biographies of women who are doing an incredible job on issues of technology and the Internet? Simple: the contributions of these women do not have visibility on the Internet.
At many Internet Governance forums, we often highlight the contributions of the founding fathers, but how do we inspire girls to join ICTs – information and communication technologies – if we never mention women?
For this year’s International Girls in ICT Day, the Internet Society’s Special Interest Group for Women organized the 1st Global Editathon Girls in ICT. With the support of Chapters and organizations from all around the world, this initiative had a clear goal: to create local content written about and by women to make their work in technology visible.
Read about the Editathon on Twitter!
Only 17% of the Wikipedia content is about women and approximately 8.8% of the content in Wikipedia in Spanish is about women scientists. Where are those women who make a difference in science and technology? Do they exist? Of course they do!
“First Global Editathon Girls in ICT, was a huge experience for us, especially because Cape Verde could participate in this event.
The Week in Internet News: Email Encryption Has Efail Moment
Encryption fails: A couple of stories in the news this past week demonstrated problems with encryption, or at least, problems with deployment of encryption. One researcher demonstrated an exploitable loophole he called Efail in PGP/GPG and S/Mime software used by email clients, reports Engadget. Efail abuses the active content of HTML emails to access plain text. In addition, a malware called Telegrab is targeting the encrypted Telegram messaging service. Telegrab steals encryption keys and cache data from Telegram running on the desktop, Tom’s Hardware says.
Artificial investment: The Chinese city of Tianjin is getting serious about funding artificial intelligence projects, with an investment of about US$16 billion, reports Reuters via the Straits Times. Yes, that’s billion with a “b.” It’s part of a Chinese push to be the leading nation in AI development.
AI knows nudes: In other AI news, Facebook has released stats on the numbers of hate speech posts and posts containing nudity that its technology removed in the first quarter of 2018. In short, the social media provider’s AI is much better at flagging nudity than hate speech, reports CNBC. About 60 percent of hate speech taken down on Facebook required human intervention.
