Hackathon@AIS: Testimonies of the Fellows

The Hackathon@AIS is a yearly event, in its second year, aimed at exposing engineers from the Africa region to Open Internet Standards Development. This year, the event was held in Dakar Senegal at the Radisson Blu Hotel, from 9-10 May 2018, during the Africa Internet Summit (AIS-2018).

The event was attended by more than 75 engineers from 15 countries including 11 fellows who were supported to attend the event.

We are happy to share the testimonies of  the fellows who attended the Hackathon@AIS.

Hackathon@AIS has been a very good and enriching experience for me because it is a meeting of ICT sharing especially with the IPWAVE workshop which is a technology of the near future where we will be ready on the African continent to implement this technology and bring more to the development of the continent. It is up to us the beneficiaries of Hackathon@AIS to bring a plus to our communities. The idea of Hackathon is very beneficial for the development of Africa. Thank you AFRINIC and ISOC.

Future Thinking: Arnaud Castaignet on Estonia’s e-citizenship

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. In May 2018, we interviewed Arnaud Castaignet, head of public relations for Estonia’s e-Residency programme.

Mr Arnaud Castaignet is the head of public relations for the Republic of Estonia’s e-Residency programme, a government-issued digital ID offering the freedom to join a community of digitally empowered citizens and open and run a global EU company fully online from anywhere in the world. Previously, he worked for the French President François Hollande as a digital strategist. Arnaud is also a Board Member of Open Diplomacy, a Paris-based think tank established in 2010, and a member of the Young Transatlantic Network of Future Leaders, a flagship initiative of the German Marshall Fund of the United States specifically geared toward young professionals 35 years old and younger. Estonia not only became the first country to say that Internet access was a human right, but has given their citizens free public WiFi, enabled them to vote online since 2005, and are protecting them with strong privacy, transparency Continue reading

Snabb Switch Update on Software Gone Wild

In 2014, we did a series of podcasts on Snabb Switch (Snabb Switch and OpenStack, Deep Dive), a software-only switch delivering 10-20 Gbps of forwarded bandwidth per x86 core. In the meantime, Snabb community slowly expanded, optimized the switching code, built a number of solutions on top of the packet forwarding core, and even forked a just-in-time Lua compiler to get better performance.

To find out the details, listen to Episode 91 of Software Gone Wild in which Luke Gorrie explained how far the Snabb project has progressed in the last four years.

BDS: A centralized near-optimal overlay network for inter-datacenter data replication

BDS: A centralized near-optimal overlay network for inter-datacenter data replication Zhang et al., EuroSys’18

(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).

This is the story of how inter-datacenter multicast transfers at Baidu were sped-up by a factor of 3-5x. That’s a big deal!

For large-scale online service providers, such as Google, Facebook, and Baidu, an important data communication pattern is inter-DC multicast of bulk data — replicating massive amounts of data (e.g., user logs, web search indexes, photo sharing, blog posts) from one DC to multiple DCs in geo-distributed locations.

To set the scene, the authors study inter-DC traffic at Baidu over a period of seven days. Nearly all inter-DC traffic is multicast (91.1%), highlighting the importance of optimising the multicast use case.

When looking at the individual transfers, there is great diversity in the source and destination DCs. Thus it’s not going to suffice to pre-configure a few select routes: “we need a system to automatically route and schedule any given inter-DC multicast transfers.”

60% of the transferred files are over 1TB Continue reading

Comparing files and directories with the diff and comm Linux commands

There are a number of ways to compare files and directories on Linux systems. The diff, colordiff, and wdiff commands are just a sampling of commands that you're likely to run into. Another is comm. The command (think "common") lets you compare files in side-by-side columns the contents of individual files.Where diff gives you a display like this showing the lines that are different and the location of the differences, comm offers some different options with a focus on common content. Let's look at the default output and then some other features.Here's some diff output — displaying the lines that are different in the two files and using < and > signs to indicate which file each line came from.To read this article in full, please click here

Network-intelligence platforms, cloud fuel a run on faster Ethernet

2018 is shaping up to be a banner year for all things Ethernet.First of all, the ubiquitous networking technology is having a banner year already in the data center where in the first quarter alone, the switching market recorded its strongest year-over-year revenue growth in over five years, and 100G Ethernet port shipments more than doubled year-over-year, according to a report by Dell’Oro Group researchers.[ Now see who's developing quantum computers.] The 16-percent switching growth was, "driven by the large-tier cloud hyperscalers such as Amazon, Google, Microsoft and Facebook but also by enterprise customers,” said Sameh Boujelbene, senior director at Dell’Oro.To read this article in full, please click here
