The traffic control (TC) framework of the Linux Kernel provides a rich set of components for packet control and classification. Recent work in TC with the eBPF classifier has highlighted the richness of this framework and raises the question of how TC could be leveraged to offload classification from Open vSwitch. In such a model, TC could also serve as an abstraction layer where classification could seamlessly be offloaded to other devices, such as an intelligent NIC, through the use of eBPF. This presentation will explore these offload opportunities and suggest ways in which OVS may benefit from leveraging TC classification.
