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

The Program Committee has accepted another nutsnbolts talk. The Devlink health mechanism provides Real Time Alerting when something bad happens to a PCI device. The primary goals are to provide alert debug information, self healing of discovered issues and help collect useful debug details for vendor support. Eran Et Al will discuss the design behind the Devlink health mechanism. What should a Device driver author creating a "health reporter" provide to the Devlink health subsystem? Come and hear it all, uncensored. More info: https://www.netdevconf.org/0x13/session.html?devlink-health-reporting-and-r… cheers, jamal

0x13: Talk Accepted, Skb Meta Data Extensions
by Jamal Hadi Salim 12 Jan '19

12 Jan '19

The Program Committee has accepted another nutsnbolts talk. Dynamic skb metadata extension is a refreshing new feature added upstream recently (see commit df5042f4c5b9). A net subsystem can associate metadatum to an skb through its life span without affecting the size of the sk_buff structure. Oh, the things you can do with this new found freedom! Florian Westphal will go into the deep guts of this feature and then digest it to make it tasty for your consumption. Come see him in action.

0x13: Talk Accepted, NVMe over TCP/IP
by Jamal Hadi Salim 07 Jan '19

07 Jan '19

Our first paper accepted by the Program Committee NVMe is hot! Imagine writing to storage and not having to twiddle your thumbs while waiting for a write to complete. NVMe over Fabrics (NVMe-OF) is changing how we think about remote storage. Using TCP as a transport alternative to RDMA or FC brings forward an interesting perspective in relation to the networking stack. Sagi Grimberg will tell you how this stuff works before going over the linux implementation and finally soliciting feedback on some outstanding issues. Come listen, learn, and converse.
