In this presentation, Mr. Herbert discusses the layered architecture of Open vSwitch. Tom will discuss the OVSDB and Open Flow control protocol and the specific mechanism and internal API's with which OVS's layered architecture provides independence of the data plane from the control plane. Specifically, he discusses how user space accelerated software data paths can provide enhanced performance over the Linux kernel in some circumstances at wire data rates. The talk covers DPDK as an example of a user space data plane as well as the advantages and disadvantages of DPDK with respect to the LInux Kernel data plane in terms of configuration, flexibility, provisioning and network interfaces. Finally, he provides a discussion about the implications of utilizing OVS with DPDK or another accelerated software data plane to OPNFV higher level networking functions.
