== Talks ==

Talk 1: The Problems with RTBH

James Bensley (Inter.link)

A recent large scale DDoS attack against one of our customers revealed
some problems with our existing 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.

Talk 2: Building an open source BNG

Brandon Spendlove (veesix ::networks)

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
