2015-01-09: accepted proposal - Jiří Pírko - Implementing Open vSwitch datapath using TC

This is a proposal to illustrate how to implement the Open vSwitch datapath using the Linux traffic control (TC) subsystem. The TC subsystem existed long before OVS and offers more flexibility. As an example it allows creating multiple types of classifiers which can be added as plugins. It offers capability of working on the ingress or egress path of any Linux netdev which means the datapath does not require the central focus to be a switch.

This talk will go into covering the missing classifiers and actions that are implemented in OVS datapath and needed by TC to achieve this goal. The talk will describe recent updates being done and also the planned ones to add code-reusability to some of the ovs datapath actions and how they are used by tc to achieve the stated goal.
