The Tunnel Monster - Stephen Hemminger

With the growth of virtual networking has come a new set of problems all caused by tunneling. Tunnels used to be limited to VPN's, getting around pesky firewalls (see RFC3093). Now everbody's doing them and inventing new standards with more confusing names like NVGRE, VXVLAN and STT. This talk will explore what these are, what problems they cause and how well Linux does (or does not) support htem.

Stephen has been involved with Linux drivers, networking, routing and bridging. In addition to working for Vyatta, in developing their open source routing platform he has contributed the "netem" network emulator, several network drivers and is the maintainer several utilities.
