Open vSwitch (OVS) is an open source framework for software-defined networking (SDN) and is useful in virtualized environments. Just like conventional network stacks, OVS can offload tasks to the hardware running on the network interface card (NIC) to speed up the processing of network packets. However, dozens of functions are invoked in a chain to achieve hardware offload. This article takes you through the chain of functions to help you debug networking problems with OVS.
