Talk 2: Viking Monitoring: A very punny adventure!

Supercomputers! Yes, no, really. York University still maintains a supercomputer, by the name of Viking (of course). But how does one look after such a beast? More precisely, how do you keep track of 175 compute nodes all working together? Nat’s unique insights into how the University monitor their clustered supercomputer is sure to be an enjoyable & informative run through looking after one of the more illusive style of networked systems.

Talk 1: RFC8981 – Temporary Address Extensions for Stateless Address Autoconfiguration in IPv6

This newly published RFC describes an extension to IPv6 Stateless Address Autoconfiguration, which causes hosts to generate temporary addresses with randomised interface identifiers. Changing addresses over time limits the window of time during which eavesdroppers may perform address-based network-activity correlation. Additionally, it reduces the window of exposure for a host being accessible via the same address over a period of time.

Presenter: Fernando Gont (SI6 Networks)

Talk 2: L2TP 101: On-Ramp to Consuming Wholesale Broadband Services
