The History of Networking: Ivan Pepelnjak and the Internet Behind the Iron Curtain
Ivan Pepelnjak was a founding member of the first IX in Slovenia twenty-five years ago. He joins us to describe the origins of the Internet, from the first dial-up circuits to the founding of the first IX and local DNS services here on the History of Networking. Ivan is an independent consultant and trainer; his work can be found at https://ipspace.net.

When people connect to the Internet, they can change the world for the better. And so many people have done just that, using this transformative technology to make strides in education, economic opportunity, and health outcomes. But Internet access is only part of the equation. There’s now a different kind of divide: the gap between those who have the knowledge and skills to use the Internet to empower themselves and their communities – and those who don’t.
To address this gap, the Internet Society Foundation is launching SCILLS: Strengthening Communities, Improving Lives and Livelihoods. The program aims to expand economic growth, improve health outcomes, and increase educational opportunities – by supporting communities to more knowledgeably and skillfully use the Internet.
Are you working to close this gap? The Internet Society Foundation wants to hear from you!
In its pilot year, the program is open to eligible organizations in Bangladesh, Colombia, and Senegal, with expansion to additional countries planned in coming years. It provides grants of up to $150,000 USD for projects lasting up to 24 months. Applications are open between 9 June and 3 July, and grantees will be announced in early September.
The Internet is for everyone – a critical lifeline that can Continue reading
UtahFS: Encrypted File Storage
Encryption is one of the most powerful technologies that everyone uses on a daily basis without realizing it. Transport-layer encryption, which protects data as it’s sent across the Internet to its intended destination, is now ubiquitous because it’s a fundamental tool for creating a trustworthy Internet. Disk encryption, which protects data while it’s sitting idly on your phone or laptop’s hard drive, is also becoming ubiquitous because it prevents anybody who steals your device from also being able to see what’s on your desktop or read your email.
The next improvement on this technology that’s starting to gain popularity is end-to-end encryption, which refers to a system where only the end-users are able to access their data -- not any intermediate service providers. Some of the most popular examples of this type of encryption are chat apps like WhatsApp and Signal. End-to-end encryption significantly reduces the likelihood of a user’s data being maliciously stolen from, or otherwise mishandled by a service provider. This is because even if the service provider loses the data, nobody will have the keys to decrypt it!
Several months ago, I realized that I had a lot of sensitive files on my computer (my diary, if Continue reading
Cloud Networking Architectures
There’s one thing no cloud vendor ever managed to change: virtual machines running on top of cloud infrastructure expect to have Ethernet interfaces.
It doesn’t matter if the virtual Ethernet Network Interface Cards (NICs) are implemented with software emulation of actual hardware (VMware emulated the ancient Novell NE1000 NIC) or with paravirtual drivers - the virtual machines expect to send and receive Ethernet frames. What happens beyond the Ethernet NIC depends on the cloud implementation details.

Is QUIC really Quicker?
QUIC is a relatively new data transport protocol developed by Google, and currently in line to become the default transport for the upcoming HTTP standard. Because of this, it behooves every network engineer to understand a little about this protocol, how it operates, and what impact it will have on the network. We did record a History of Networking episode on QUIC, if you want some background.
In a recent Communications of the ACM article, a group of researchers (Kakhi et al.) used a modified implementation of QUIC to measure its performance under different network conditions, directly comparing it to TCPs performance under the same conditions. Since the current implementations of QUIC use the same congestion control as TCP—Cubic—the only differences in performance should be code tuning in estimating the round-trip timer (RTT) for congestion control, QUIC’s ability to form a session in a single RTT, and QUIC’s ability to carry multiple streams in a single connection. The researchers asked two questions in this paper: how does QUIC interact with TCP flows on the same network, and does UIC perform better than TCP in all situations, or only some?
To answer the first question, the authors tried running QUIC Continue reading
