0x13: Tutorial, QUIC
by Jamal Hadi Salim 02 Feb '19

02 Feb '19

Our illustrious PC has accepted the first tutorial. Quick UDP Internet Connections, pronounced 'quick' is a new important transport which is growing at a phenomenal rate. Studies have shown by November 2017, QUIC already represented 20% of the total mobile traffic[1] and grew over 200% in two years. There are other advantages for QUIC; refer to 0x12 talk[2]. QUIC is implemented on top of UDP making it much easier to deploy improvements and fixes when compared to TCP which is in the kernel (and therefore requires kernel patch submissions and process overhead). Ok, so what do you know about QUIC? How do you debug QUIC on the wire? What is out there if you wanted to write an application on top? The two foremost QUIC gurus Jana Iyengar and Ian Swett will be giving a tutorial on the subject. This is what some would call hearing it from the horses' mouth(s?). Come, listen, participate and learn.

As in, not on > netlink itself. Marcelo, you are right. Its about covering the ever growing netlink API documentation.

0x13: Talk Accepted, P4 Compiler Backend for TC
by Jamal Hadi Salim 23 Jan '19

23 Jan '19

The Program Committee has accepted another talk. Modern switching architectures deal with Terabits of data per second. Imagine 32 ports at 400Gbps; wait.. translate that to 128 ports of 100Gbps; too much? Make that 256 ports of 25G ports; maybe we can talk about 1280 ports of 10Gbps? One ASIC, friends. You get the point. How do you make these beasts programmable through standard Linux to allow adding your own network functions? One industry approach is to use P4. Marian Pritsak and Matty Kadosh will give a Moonshot talk on taking advantage of standard linux features by creating a Linux Pipeline with with P4 utilizing the traffic control(TC) subsystem. They have written a P4 to TC compiler backend with switchdev as the HW offload backend. More info: https://www.netdevconf.org/0x13/session.html?p4-compiler-backend-for-tc cheers, jamal
