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.

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?

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
Data Center Routing with RIFT on Software Gone Wild
Years ago Petr Lapukhov decided that it’s a waste of time to try to make OSPF or IS-IS work in large-scale data center leaf-and-spine fabrics and figured out how to use BGP as a better IGP.
In the meantime, old-time routing gurus started designing routing protocols targeting a specific environment: highly meshed leaf-and-spine fabrics. First in the list: Routing in Fat Trees (RIFT).

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
sudo mn --custom sflow-rt/extras/sflow.py --link tc,bw=10 \
--topo tree,depth=4,fanout=2 --test iperf
sudo mn --custom sflow-rt/extras/sflow.py --link tc,bw=10 \It's also easy to create Custom Topologies. The following command creates the example custom topology, topo-2sw-2host.py, that ships with Mininet:
--topo linear,4 --test iperf

Service Providers Get a Little Testy With Vendors Regarding SDN
Unfortunately for vendors, they don’t have the luxury of sitting on stage and defending their point of view. But vendors aren’t going to provide products based on open source unless there’s money to be made.
Meet the APRICOT 2018 Fellows
The Asia Pacific Regional Internet Conference on Operational Technologies (APRICOT) is an annual event that brings together Internet engineers and networking experts, government representatives, Internet business leaders, and other interested parties from around the world to learn from training workshops and tutorials, attend technical presentations, discuss policies, and extend social and professional networks with like-minded peers. This year’s event was held in Kathmandu, Nepal from 19-28 February.
The Internet Society Asia-Pacific Bureau has a long-term partnership with APRICOT and proudly sponsors its fellowship program, providing financial support for individuals from developing economies to attend the event, and to contribute to discussions about Internet operations, technologies and development. This year the Internet Society sponsored a total of 13 fellows to APRICOT 2018, split between the technical workshops and the conference week, depending on their areas of interest. 75% of these fellows were females, endorsing our focus to inspire and facilitate the participation of women in the technology sector and to #ShineTheLight!
We had an opportunity to meet some of these fellows, to know more about them and their experience as a fellow.

Three more US data centers! Jacksonville, Memphis and Tallahassee
Good things come in threes! Following the launch of three data centers each in the Baltics (Riga, Tallinn, Vilnius) and in the Canadian Prairies (Calgary, Saskatoon, Winnipeg), we're thrilled to announce three new data centers in the Southern United States!
Located in Jacksonville (Florida), Memphis (Tennessee), and Tallahassee (Florida), they represent the 146th, 147th and 148th cities across our growing global network, and our 40th, 41st and 42nd cities just in North America. They join existing Cloudflare facilities in the US, including other Florida / Tennessee deployments such as Miami, Tampa and Nashville. Just in March, we've added deployments in 28 new cities worldwide, which help reduce latency to millions of Internet properties using Cloudflare, while expanding our capacity to withstand new and familiar attacks.
