0x12: Nuts-n-Bolts Talk! Suricata, an XDP adventure
by Jamal Hadi Salim 10 May '18

10 May '18

The program committee has accepted another exciting talk! Suricata is a widely deployed open source IDS/IPS/NSM. Suricata 4.1 will include eBPF and XDP support. In this respect, Suricata is amongst pioneers to deploy these technologies in a production environment. The journey to get to eBPF and XDP support and remove the cobwebs took about 2 years. Eric Leblond will describe some of the challenges met and how they were addressed to get to production level quality. More info: https://www.netdevconf.org/0x12/session.html?suricata-an-xdp-adventure cheers, jamal PS:- Another reminder that: 1) Registration early bird deadline (before prices go up) is June 1st. 2) We do offer bursaries for attending the conference.

0x12: Hands on! Introduction to FRRouting
by Jamal Hadi Salim 08 May '18

08 May '18

In this 1.5 hour instructor-led tutorial, Donald Sharp(FRRouting maintainer) will start by introducing the FRRouting Suite to the unitiated. He will then guide us into a basic network configuration. In the second half of the tutorial, Donald will delve deeper into more advanced features on how FRR fits into the classic Data Centre architecture. https://www.netdevconf.org/0x12/session.html?introduction-to-frrouting cheers, jamal PS:- Reminder: Early bird registration offer ends June 1st.

0x12: Moonshot Talk! A PCC-Vivace Kernel Module for Congestion Control
by Jamal Hadi Salim 07 May '18

07 May '18

Folks, Nathan Jay et al assert that there is no one-size-fits-all TCP congestion control algorithm. Different apps have different goals for their service lifetimes: Streaming video apps are sensitive to bandwidth fluctuations, voice chats desire low latency and bulk transfers only care about completion time. Varying link characteristics add another dimension to a congestion control algorithm: hardwired assumptions about the cause of packet loss or measured latency inflation can lead to reduced application performance. PCC-Vivace was created to address these issues. PCC-Vivace congestion control algorithm provides an explicit utility function that allows developers to provide weights to different performance metrics like throughput, latency, packet loss and jitter. PCC-Vivace's online learning framework also allows it to adapt to a variety of network conditions, consistently delivering high performance. The talk will discuss the challenges of implementing PCC-Vivace in the Linux kernel. Nathan will present initial results comparing the performance of Vivace with other existing Linux congestion controllers(BBR etc). The talk will also demonstrate the implementation's flexibility by creating and testing a variety of utility functions.

0x12: NutsNBolts Talk! Challenges migrating from NDIV to XDP
by Jamal Hadi Salim 04 May '18

04 May '18

HAProxy is a well known high performance TCP/HTTP load balancer used as a front end to applications by many very-large sites. Often HAProxy is stationed at the frontiers of the wild wild ^Wwest internet in the defense against DDOS - and at the heart of the storm sits PacketShield. PacketShield is built using NDIV. NDIV has been deployed very effectively todate and handles the intended line-rate 10Gbps processing under a variety of hostile real-world DDOS attacks. Willy Tarreau and Emeric Brun have been contemplating migrating NDIV to use XDP. In this talk they will describe what NDIV does well and what is currently lacking with XDP to make it convincing to make the jump. More details: https://www.netdevconf.org/0x12/session.html?challenges-migrating-from-ndiv… Reminder: Early bird registration expires on June 1st. cheers, jamal

0x12: Nuts-and-bolts Talk: Using eBPF for RDS filtering
by Jamal Hadi Salim 03 May '18

03 May '18

Tushar Dave will share his experiences in implementing Reliable Datagram Socket (RDS) filtering and firewalling. RDS sits on top of both TCP and IB, which presents a challenge: while TCP deals with skbs, IB/RDMA deals with scatterlists. Traditional firewalling with netfilter deals only with skbs. Tushar is looking for a unified solution for both TCP and IB. To this end he is adding/extending eBPF helpers to process messages that are in the form of struct scatterlist. https://www.netdevconf.org/0x12/session.html?using-ebpf-for-rds-filtering Reminder: Early bird registration expires on June 1st. cheers, jamal

0x12: Moonshot Talk: BBRx: Extending BBR for Customized TCP Performance
by Jamal Hadi Salim 30 Apr '18

30 Apr '18

The future of optimal TCP involves robots! Jae Won Chung et al will discuss an extension to BBR they call BBRx which is loosely coupled to machine learning. They will describe how they study TCP path attributes in user space at runtime to find an optimal throughput-delay operating point. The results are then fed back to the kernel to tweak it. Performance of BBRx is evaluated in both LTE mobile as well as telco wireline environments and compared with classical CUBIC and BBR. cheers, jamal
