Dave Taht
by Tom Herbert 03 Apr '25

03 Apr '25

Dear Netdev Community, I am very sad to report the passing of Dave Taht. Dave was one of our own! He was a long time contributor and participant in Netdev, and was committed to solving Bufferbloat and improving the Internet for everyone. He will be missed! Anyone who has attended Netdev conferences knows that Dave was one of our more "interesting" participants. He was full of life and a very kind soul. At Netdev 0x17, he shared his wonderful music with us in one of the most memorable sessions in Netdev history. Below are links to a couple of songs from that and also a link to the whole session. "There's something happening here" https://youtu.be/bk6umx95ouo "Hallelujah" https://youtu.be/UnGqbDSIPzQ "Music BoF from Netdev0x17" https://youtu.be/D9RGX6QFm5E Thanks, Tom -- on behalf of Netdev Society Board

0x19: Keynote, Understanding and Improving Robustness of Networked Systems With Machine Learning
by Jamal Hadi Salim 01 Mar '25

01 Mar '25

We are honored to have Brighten Godfrey as our keynote speaker for 0x19! Brighten is currently a Professor in the Siebel School of Computing and Data Science at the University of Illinois Urbana-Champaign. He co-founded and served as CTO of network verification pioneer Veriflow which was acquired by VMware (now Broadcom, where Brighten still serves part-time). Brighten has a strong background in networked systems and algorithms and has received multiple awards for his work. In this keynote talk, Brighten asserts that, while networks are essential infrastructure they are complex and hard to fully understand, even for experts. This complexity makes it difficult to ensure reliable performance. Brighten argues that Machine Learning(ML) can be put to use to analyze and understand complex network systems and improve their robustness. Brighten will further discuss using ML as an "adversary" to find weaknesses in networked environments where congestion control implementations perform poorly, and help to automatically diagnose performance problems in distributed cloud applications.

0x19: Talk, Host-based TCP Connection Migration
by Jamal Hadi Salim 09 Feb '25

09 Feb '25

Current approaches to migrate TCP connections (using TCP_REPAIR) across machines require middle box support for seamless transparency. Most existing proposals use the Intel/Tofino programmable P4 switch for this purpose, an approach which is operationally burdensome. Shuo Li, Steven Chien, Tianyi Gao and Michio Honda describe a proposal that obviates the need for programmable switches. In their approach, the host that has established the connection is responsible for the traffic redirection. They use a combination of TC hardware offload and eBPF to achieve their goals. The authors will go over the implementation details and challenges and finally illustrate how they integrate their connection migration method with Ceph, a widely-used object storage system to illustrate a specific use case.

0x19: Talk, Reservoir to the tap: with fairness and humility
by Jamal Hadi Salim 09 Feb '25

09 Feb '25

Fintech workloads and few other modern work loads require very fine grained control (down to a couple of milliseconds) over packet pacing and at the same time be able to do this for millions of flows; all requiring different granularity of flow pacing. In this talk, Anjali S Jain, Vadivel Kannappa, Joshua Hay, Robert Hathway, Magnus Karlsson, Chihjen Chang, Naren Mididaddi, Priyalee Kushwaha and Milena Olech go into implementation details of how to achieve these requirements.

Communication via Internal Shared Memory (ISM) - Time to open up
by Jamal Hadi Salim 09 Feb '25

09 Feb '25

Internal Shared Memory (ISM) is a method for synchronous, access controlled, direct memory access into dedicated memory regions between systems that share the same physical memory. With increased popularity of using shared memory semantics over the network protocols (see all the AI/ML craze going on), this talk will shed some light on these many years of experience on huge mainframes and other related efforts. In this talk Alexandra Winter will demystify for us ISM, its features and usecases, and explain several proposals that have been made to extend the usage of ISM. Alexandra will further discuss what would be the best way to provide clean interfaces in the Linux kernel, to enable future extensions. An early RFC has been sent to the netdev mailing list with a proposal for an ism layer - to finally make it open to the masses. Details: https://netdevconf.info/0x19/12 cheers, jamal

0x19: Talk, Optimizing Bandwidth Allocation with ETS and Traffic Classes
by Jamal Hadi Salim 09 Feb '25

09 Feb '25

In the current deployed approach in Linux, the operator does not have much control over how wire bandwidth is allocated between VFs. For example, when provisioned, a 50Gbps PF's equally split between two VFs, giving each 25Gbps, with traffic classes (e.g., TC0 and TC1) limited to percentages of these smaller allocations. Carolina Jubran says implementing ETS hardware support allows for control over such allocations. Using TC bandwidth allocation, the PF can instead be divided directly into 80% for TC0 and 20% for TC1 across the two VFs. In this talk, Carolina will describe the insufficiency of existing approaches to solve these problems, reference previous work, and demonstrate how this implementation improves resource allocation across VFs by applying traffic class-based bandwidth proportions, supported by real-world results and a demo.
