Open vSwitch - the good, the bad and the ugly

This proposal has been accepted as a session.


One Line Summary

This talk shares our experience with Open vSwitch from the past year, both as users and active developers.


This talk covers some of the work we’ve done in the past year, both to the OVS kernel module and to the tuntap driver. The work includes feature enhancements such as dynamic GRE tunneling, L3-matching in the OVS kernel module, and DOS prevention. It also covers a number of performance tuning work to the tuntap driver. The talk concludes with a number of issues we’ve encountered when trying to retrofit some common Linux stack features to OVS.
