Show 383: Optimizing Internet Traffic With Expereo (Sponsored)

BGP is good for keeping the Internet connected. And that s about it. BGP isn t good at optimizing the path between two endpoints, as it s more about optimizing service provider costs than traffic performance.

Therefore, there are products on the market that optimize your traffic flows across the Internet despite default BGP behavior. Some of these products actually manipulate BGP, which will be the focus of our sponsored show today. Our sponsor Expereo is here to discuss their XCA and XCA Edge products with us.

Joining us from Expereo are Francois Devienne, VP of Networks; and Sander Barens, VP of Commercial Development.

Expereo is a managed service provider. We discuss how the company optimizes BGP to get the best out of the Internet, and explore Expereo’s XCA and XCA Edge products.

Weekend Reads 033018: Olympic Destroyer, SONiC, and all the rest

The crippling Olympic Destroyer attack that hit several systems supporting the Pyeongchang Winter Olympics last month may have forever changed the game of attack attribution: the sophisticated attackers created a convincing forgery of malware associated with the North Korean nation-state Lazarus Group, fooling several experts who initially pinned the blame for the attacks on the DPRK. —Kelly Jackson Higgins @Dark Reading

SONiC is the default switch OS powering Azure and many other parts of the Microsoft Cloud. Since last year’s Summit, we have grown its footprint substantially and are now also powering services such as our AI platform, making sure researches have the very best experience when working on solving some of the world’s most pressing problems. —Yousef Khalidi @Azure

For decades, academics and technologists have sparred with the government over access to crypographic technology. In the 1970s, when crypto started to become an academic discipline, the NSA was worried, fearing that they’d lose the ability to read other countries’ traffic. And they acted. For example, they exerted pressure to weaken DES. —Steve Bellovin @CircleID

Cybersecurity attacks have become a weekly occurrence in many news columns. One recent example was that of one of our customers, QIWI payment system, successfully Continue reading

Juma Baldeh: Breaking Barriers to Access in Gambia

How do you shift the cultural stigma around technology and gender? As Juma Baldeh has proven in Gambia, you do it one girl at a time. Baldeh founded Hackathon Girls Banjul for girls ages 8 to 18 in her home country, in coordination with the Mozilla Foundation. As the first technology club of its kind there, members receive six months of free weekly classes on web literacy and basic computing skills. More importantly, the club gives more than 40 girls a safe space to collaborate and share experiences as they work together on projects for a tech-savvy Gambia.

“Too often I witness young girls, who are skilled in math and science, lose hope as they prepare for interviews and professional positions,” Baldeh said. “Right now, many girls in this field leave it because they think computer jobs are too difficult and they lose confidence at some point.”

The club started with a small space and just five girls, training to be proficient in basic computing skills, computer programing, online security and privacy, and research and networking. Through these skills the girls can then go on to civic participation, economic empowerment, and leadership roles. One of the many problems with Continue reading

Short Take – Cisco Disaggregation Announcement

In this Network Collective short take, Jordan Martin shares his thoughts on the recent announcement from Cisco that they will be offering disaggregated solutions. Has Cisco seen the light? Will Cisco abandon hardware completely? Or are the doing all of this for other reasons?

The cloud continues to drive network evolution

It’s fair to say that there has never been a bigger driver of network evolution than the cloud. The reason for this is the cloud is a fundamentally different kind of compute paradigm, as it enables applications, data, and architecture changes to be done seemingly instantly. Cloud-native infrastructure is what enables mobile app developers to roll out new versions daily if they so choose.The cloud is network-centric Another fact about the cloud is that it is a network-centric compute model, so a poorly performing network leads to equally poorly performing applications. A lack of network agility means DevOps teams need to sit around twiddling their thumbs while network operations make changes to the network. To read this article in full, please click here

Power Failure Leaves Brazilian Internet In The Dark

On Wednesday, March 21, a massive power failure impacted large parts of northern Brazil, leaving tens of millions of people without electricity. Beginning at about 3:40pm local time (18:40 UTC), the outage was reportedly due to the failure of a transmission line near the Belo Monte hydroelectric station.

As occurred in a major power outage in Brazil in 2009, this power failure had a measureable impact on the country’s Internet. This is illustrated below through graphs from Oracle Dyn’s Internet Intelligence team based on BGP and traceroute data, as well as graphs from Akamai’s mPulse service, based on end user Web traffic.

The graphic below depicts the counts of available networks (lower graph) and unstable networks (upper graph) for Brazil in the latter half of March 21. The number of unstable networks spikes around 18:40 UTC as routers of ISPs in Brazil began re-routing traffic away from disabled connections, while the lower graph shows that the corresponding drop in available networks (i.e. routed prefixes) was minor when compared to the total number routes that define the Internet of Brazil.

In addition to aggregating BGP routing information from around the globe, the Internet Intelligence team also performs millions of Continue reading

Technology Short Take 97

Welcome to Technology Short Take 97! This Tech Short Take marks the end of an era (sort of); it’s the last Tech Short Take published while I’m a VMware employee (today is my last day; see here for more details). But enough about me—let’s talk some tech! This Short Take may be a bit longer than some, so buckle up.

Mininet weathermap

Mininet dashboard is a real-time dashboard displaying traffic information from Mininet virtual networks. The screen capture demonstrates the real-time network weather map capability that was recently added to the dashboard. The torus topology is displayed and link widths are updated every second to reflect traffic. In this example a large flow between switches s1x1 and s3x3 is routed via s1x3.

The network was created using the following Mininet command:
sudo mn --custom=sflow-rt/extras/sflow.py --link tc,bw=10 \
--topo torus,3,3 --switch ovsbr,stp=1 --test iperf
In the screen capture above you can clearly see the large flow traversing switches, s4, s3, s2, s1, s9, s13, and s15 in a tree topology. The network was created using the following command: 
sudo mn --custom sflow-rt/extras/sflow.py --link tc,bw=10 \
--topo tree,depth=4,fanout=2 --test iperf
The screen capture above shows a large flow traversing switches s1, s2, s3, and s4 in a linear topology. The network was created using the following command: 
sudo mn --custom sflow-rt/extras/sflow.py --link tc,bw=10 \
--topo linear,4 --test iperf
It's also easy to create Custom Topologies. The following command creates the example custom topology, topo-2sw-2host.py, that ships with Mininet:
sudo mn --custom ~/mininet/custom/topo-2sw-2host.py,sflow-rt/extras/sflow.py  Continue reading

WannaCry after one year

In the news, Boeing (an aircraft maker) has been "targeted by a WannaCry virus attack". Phrased this way, it's implausible. There are no new attacks targeting people with WannaCry. There is either no WannaCry, or it's simply a continuation of the attack from a year ago.


It's possible what happened is that an anti-virus product called a new virus "WannaCry". Virus families are often related, and sometimes a distant relative gets called the same thing. I know this watching the way various anti-virus products label my own software, which isn't a virus, but which virus writers often include with their own stuff. The Lazarus group, which is believed to be responsible for WannaCry, have whole virus families like this. Thus, just because an AV product claims you are infected with WannaCry doesn't mean it's the same thing that everyone else is calling WannaCry.

Famously, WannaCry was the first virus/ransomware/worm that used the NSA ETERNALBLUE exploit. Other viruses have since added the exploit, and of course, hackers use it when attacking systems. It may be that a network intrusion detection system detected ETERNALBLUE, which people then assumed was due to WannaCry. It may actually have been an nPetya infection instead (nPetya Continue reading

How converged infrastructure can accelerate the AI journey

The technology that powers businesses is evolving faster than ever before, allowing us to do more than we ever thought possible. Things that were once only seen in science fiction movies are actually coming to life.One of these areas is the field of artificial intelligence (AI). We’re on the verge of having machines diagnose cancer, map out the universe, take over dangerous jobs, and drive us around. The downside to the rapid evolution has been a rise in complexity. Putting together the infrastructure and software to power AI-based systems can often take months to build, tune, and tweak so that it runs optimally.Compounding the difficulty is that AI infrastructure is often deployed by data scientists who do not have the same level of technical acumen as the IT team. To read this article in full, please click here
