IPv6 Buzz 042: Why Wireless Is A Smart Place To Start With IPv6
If you're looking for a way to bring IPv6 into your environment, the WLAN may be your best bet. Find out why in the latest episode of IPv6 Buzz with guest Jeffry Handal. Jeffry cut his teeth with an early v6 deployment on the wireless network of Louisiana State University (LSU). This WLAN serves 40,000 users and over 100,000 devices. He shares his experiences and talks about how vendor adoption of v6 had advanced since that deployment.

Security and encryption experts from around the world are calling on the Indian Ministry of Electronics and Information Technology (MeiTy) to reconsider proposed amendments to intermediary liability rules that could weaken security and limit the use of strong encryption on the Internet. Coordinated by the Internet Society, nearly thirty computer security and cryptography experts from around the world signed “Open Letter: Concerns with Amendments to India’s Information Technology (Intermediaries Guidelines) Rules under the Information Technology Act.”
MeiTy is revising proposed amendments to the Information Technology (Intermediaries Guidelines) Rules. The proposed amendments would require intermediaries, like content platforms, Internet service providers, cybercafés, and others, to abide by strict, onerous requirements in order to not be held liable for the content sent or posted by their users. Freedom from intermediary liability is an important aspect of communications over the Internet. Without it, people cannot build and maintain platforms and services that have the ability to easily handle to billions of people.
The letter highlights concerns with these new rules, specifically requirements that intermediaries monitor and filter their users’ content. As these security experts state, “by tying intermediaries’ protection from liability to their ability to monitor communications being sent across their platforms or systems, the amendments would limit Continue reading
Worth Reading: Apple II Had the Lowest Input Latency Ever
It's amazing how heaping layers of complexity (see also: SDN or intent-based whatever) manages to destroy performance faster than Moore's law delivers it. The computer with lowest keyboard-to-screen latency was (supposedly) Apple II built in 1983, with modern Linux having keyboard-to-screen RTT matching the transatlantic links.
No surprise there: Linux has been getting slower with every kernel release and it takes an enormous effort to fine-tune it (assuming you know what to tune). Keep that in mind the next time someone with a hefty PPT slide deck will tell you to build a "provider cloud" with packet forwarding done on Linux VMs. You can make that work, and smart people made that work, but you might not have the resources to replicate their feat.

Accelerating UDP packet transmission for QUIC
This was originally published on Perf Planet's 2019 Web Performance Calendar.
QUIC, the new Internet transport protocol designed to accelerate HTTP traffic, is delivered on top of UDP datagrams, to ease deployment and avoid interference from network appliances that drop packets from unknown protocols. This also allows QUIC implementations to live in user-space, so that, for example, browsers will be able to implement new protocol features and ship them to their users without having to wait for operating systems updates.
But while a lot of work has gone into optimizing TCP implementations as much as possible over the years, including building offloading capabilities in both software (like in operating systems) and hardware (like in network interfaces), UDP hasn't received quite as much attention as TCP, which puts QUIC at a disadvantage. In this post we'll look at a few tricks that help mitigate this disadvantage for UDP, and by association QUIC.
For the purpose of this blog post we will only be concentrating on measuring throughput of QUIC connections, which, while necessary, is not enough to paint an accurate overall picture of the performance of the QUIC protocol (or its implementations) as a whole.

Indian Community Making the Right Connections
In the lead up to last month’s Internet Engineering Task Force meeting in Singapore, IETF 106, the India Internet Engineering Society (IIESoc) held its third annual Connections conference in Kolkata, India.
This pre-IETF event aims to increase participation in IETF discussions from the Asia-Pacific region, specifically India.
Like the years before it, this edition of Connections had four technology tracks across two days; the themes of which – IoT, security, routing, and research – were chosen with the audience and location in mind, given Kolkata is a major research hub in India. As such, there was record participation, with a large number of local students attending the event, many of whom were excited to learn about, discuss and contribute to the work being considered in the IETF and how they can contribute to this group.
The Importance of Being Involved
A feature of past Connections events has been the participation of IETF working group chairs and RFC contributors attending en route to the impending IETF conference. This year was no different and we were grateful to have former IETF chair, Fred Baker, who presented the keynote and shared his journey at the IETF during the meet and greet session.

Synology Running Out Of Space? Empty The Recycle Bin.
While performing end-of-year clean up on lab infrastructure, I discovered my 8 disk Synology array with about 22TB of usable storage was almost out of space. Really? What had I filled all that space with?
After a lot of digging around, I found that I had enabled the Recycle Bin on one or more Shared Folders, but had NOT created a Recycle Bin emptying schedule.
This means that over several years of shoving lots of data through the array, the various Recycle Bins attached to various Shared Folders had loaded up with cruft. I figured this out running a Storage Analyzer report.
To get my space back, the solution was to empty the Recycle Bin. One way to do that is to edit the properties of a Shared Folder and click “Empty Recycle Bin”. You’ll get a sense of relief as Storage Manager shows available space growing as the Synology removes however many million files you’ve been composting for however long.
However, I like to solve problems permanently. No one has time to manually empty recycle bins on a disk array in a distant rack. Manually. Like a savage. Yuck.
Automating a recycle bin task on a Synology box is Continue reading
