Arrival from 1830hrs. 
Talks begin promptly at 1900hrs.


Talk 1: The Problems with RTBH

A recent large scale DDoS attack against one of our customers revealed some problems with our exiting RTBH tooling. This talk aims to provide an insight into the problems with RTBH filtering from both sides of the table (as an IP Transit and DDoS protection provider, and as a customer/peer), and some ideas of what we as a community can do about it.

Presenter: James Bensley (Inter.link)


Talk 2: Building an open source BNG

Small insight into DPDK, VPP and eBPF/XDP. How I started building a software based BNG with the goal of being able to serve IPoE and PPPoE subscribers and get up to multi-hundred gigabits of throughput, how I can move forward with getting the ISP community to try it out in labs and get to a production-grade BNG on x86 hardware

Presenter: Brandon Spendlove (veesix ::networks)
