Éric Dumazet (author of the patch) is this highly productive guy working on network latency issues. He helped get CoDel into the kernel, and worked on TCP small queues (https://lwn.net/Articles/507065/ https://lwn.net/Articles/507065/) and the fair queue scheduler (https://lwn.net/Articles/564978/ https://lwn.net/Articles/564978/). Looking at the email addresses he used, I think he started working on the network stack on his spare time, while employed at SFR, a French telco. He implemented an in-kernel JIT for BPF (https://lwn.net/Articles/437981/ https://lwn.net/Articles/437981/), speeding up packet filtering; now that BPF is fast it is also used for performance profiling (filtering and aggregating in kernel) and syscall filtering.
There are of course others working in these areas, but I think Google has been going after them: Van Jacobson is a high-profile example. Dave Taht is still subsiding on ramen though (https://www.patreon.com/dtaht https://www.patreon.com/dtaht).
- sandGorgon 11y agoFor the last five years I've worked myself to the bone, mostly unpaid, to solve the "bufferbloat" problem - first by organizing and leading the team that solved it, and giving away, for free, the ideas and code for anyone to use! And I've spent tons of time later convincing standards organizations like the IETF to make the ideas standard in new equipment - and also open source makers like openwrt to retrofit the fq_codel and cake fixes into millions of older yet upgradable home routers, and helping ISPs, vendors and chipmakers understand the both the need for the fq_codel fixes, and how to implement them. wow - thanks for posting about David Taht. someone like Netflix or Google should get him on their payroll.
