You meant people at the time you sent had to refresh their browsers and i thought you meant that is a general requirement. thanks for the clarification.

0x15: Tables in the lounge
by Jamal Hadi Salim 21 Jul '21

21 Jul '21

So it turns out we can have 50 people sit on a table at the lounge. Unfortunately, once 8 people are seated it seems to add more if you are rejected because the table is full you need to refresh your browser. I know that sounds silly - but airmeet only recently added this extension and is still work in progress. Maneesh - please correct me if i didnt describe things correctly. cheers, jamal

0x15: Lounge and replay of session
by Jamal Hadi Salim 14 Jul '21

14 Jul '21

Hi, Just a reminder of two features on the conference platform We do have some really nice setup for the lounge: Tables. Once you login, go to the lounge and you should see several tables (we have 100 tables setup). You can grab a table and invite people over. You can use these tables at any time - although we encourage people to attend the sessions instead of loitering in the lounge ;-> We are also open to reserving tables. If you would like to run a meeting at the break or after or before the conference just send email to Jeremy and he can create one for you with a title of your choice so that other people can find it. For example, there is a table right now called "Happy hour" The second feature is ability to replay sessions you missed. Just go into the schedule and you will see a "replay" button on each session. cheers, jamal

by Jamal Hadi Salim 13 Jul '21

13 Jul '21

Note there is an ongoing poll of whether we should have the 30 minute break tomorrow after the TC workshop but before switchdev workshop. We do have a break today - but not one designated for tomorrow. Please vote - we are still experimenting to figure how best to do this. cheers, jamal

Another reminder: We are experimenting with a feature that will help people who are busy during the session or are in different time zones to still be able to catchup. As long as you are registered you can always login later on and replay any session you missed. cheers, jamal On 2021-07-12 7:30 a.m., Jamal Hadi Salim via people wrote: > Just a reminder that the second phase of netdevconf 0x15 starts > tomorrow, Tuesday to Wednesday. > This phase constitutes workshops and tutorials. > > Workshops on: > XDP > IOT Networking > TC > Netfilter > FRR > and Switchdev Offload > > Tutorial on: > Introduction to time synchronization over Ethernet > > See: https://netdevconf.info/0x15/accepted-sessions.html > > cheers, > jamal > _______________________________________________ > people mailing list > people(a)netdevconf.org > https://lists.netdevconf.info/cgi-bin/mailman/listinfo/people

0x15: Community Sponsor, IPsec and Network Security Association!
by Jamal Hadi Salim 06 Jul '21

06 Jul '21

We are happy to announce our first community sponsor: The IPsec and Network Security Association! Thank you for your support. What is the IPsec and Network Security Association? The aim of the IPsec and Network Security e.V. (see: https://linux-ipsec.org/) is to build a strong open source/protocol community to make network security ready for the next generation. The activities shall extend and support the work of standardization organizations with respect to real world implementation and use cases on open source operating systems. Network security technologies became increasingly important over recent years. In the view of professional attacks against the core network infrastructure happening these days, network security technologies must be continously developed to make the network infrastructure futureproof. IPsec as the major layer 3 network security protocol plays an important role in securing todays network. However, as networks continue to become more and more complex, network security technologies, like IPsec, must keep up with that increasing complexity. cheers, jamal

0x15: Industry Perspectives Panel: Vendor Perspective On Smart NICs
by Jamal Hadi Salim 03 Jul '21

03 Jul '21

We are happy to announce that the Industry Perspectives Panel will be held on July 19th at 5:50 UTC. For Netdev conf 0x15 we will get the NIC vendor's perspective on Smart NICs. Smart NICs are a new emerging type of NICs which have built in processors alongside rich ASIC-based packet processing pipelines. The tradition of the Industry Perspectives is to maintain an open mind so contrarian perspectives are accepted; for example: A vendor is allowed to say Smart NICs are a bad idea as long as they back their claim or that they dont support or want to support Linux within the NIC. By Linux we mean the Linux kernel network stack of course. Then the questions is: What are the requirements that Linux needs to support to turn around any skeptical vendor? For vendors supporting Linux, what is the format in which the kernel running within the NIC operates and interacts with the host? What is offloaded from within the NIC's kernel vs the host's? The panel format is a few technical slides from each vendor describing the features they offer, their differentiation and if they support Linux the interaction with Linux. This is followed by questions from the panel and then an open floor for audience Q&A. We will be providing more information as to which vendors will be participating in the next few days. cheers, jamal

little poll for switchdev users
by Alexander Zubkov 02 Jul '21

02 Jul '21

Hello everybody! I'll have a talk during Netdev 0x15 about how the life with Switchdev looks like. It'll be at the Switchdev Offload Workshop. And I want to collect some statistics to share during my talk. If you use switches with switchdev-based driver, I invite you to fill out a short form. I will not take much time. There are only 4 simple questions and only one is required. https://forms.gle/FZNVFJ5EgkAyzR7DA PS. If you wonder how people use Switchdev in real life, I welcome you on my talk! Of course, people already using switchdev are welcome too - you'll have your bit of sympathy!

0x15: Schedule out!
by Jamal Hadi Salim 01 Jul '21

01 Jul '21

We are pleased to announce the tentative schedule for 0x15. There may be some minor changes going forward, if any, but the overall theme will remain. For both registration and schedule for now go to: https://netdevconf.info/0x15/virtual.html This time we have good integration with calendar systems so should be easy to add to google calendar, etc. Also one nice feature in the Airmeet system this time is we are trying a setup such that if you miss a session because you are busy you can login and play the videos. As usual, once the videos are cleaned up they will be uploaded to youtube. cheers, jamal

0x15: New Talk accepted!
by Jamal Hadi Salim 01 Jul '21

01 Jul '21

Tom Herbert is still on a quest to speed up the network stack[1]. In this talk he introduces the PANDA parser with intention to replace the venerable Linux kernel Flow Dissector. Tom says the flow dissector is hard coded, convoluted making it both hard to extend and hard to maintain. (yes, he is guilty as well having been one of the originators of the flow dissector). PANDA parser is a domain specific parser that lives under the philosophy of "write once, run anywhere, run well". Unlike Flow Dissector, a PANDA Parser with metadata extraction is written in a declarative representation as opposed to imperative instructions - all in familiar C. It has been shown that while more flexible, the PANDA parser is more performant than flowdissector. The PANDA parser may be compiled to different backends, currently two implemented backends are available: an optimized userspaces C and an XDP/eBPF one. There is ongoing work on generating a plain kernel version as well which may be consumed by other part of the kernel. For any of those 3 backends, the parser definition stays unchanged.

0x15: New Talk accepted!
by Jamal Hadi Salim 01 Jul '21

Marcelo Leitner and Vlad Buslov will discuss turbo-charging the TC flower control interface and the evolution of the work that went into it over a period of two years: At least one hundred kernel patches, many changes to user space and increase in performance by a magnitude. To the datapath skeptics who are wondering why optimize the control path (reminds of the joke from not-to-be-named kernel guy under the influence "Why do we need userspace at all?"): You do care if you are constantly churning or accessing the datapath. Example workloads: - short lived container workloads where you have to add/delete access control rules, - telco environments, where efficient rule statistics are critical billing - etc. cheers, jamal PS: Registration is open, see: https://netdevconf.info/0x15/registration.html PPS: We are looking to post the schedule today
