Need for Speed - using DPDK and SR-IOV

Trevor McCasland is going to talk about DPDK and SR-IOV

In this talk Trevor will be presenting a new feature that can be introduced in OpenStack by integration of DPDK PMD drivers using SR-IOV for NFV workloads. The VMs will be attached to hostdev devices which will increase the throughput for the NFV applications and help get as close to wire-line speed as possible for virtual machines. This implementation provides better performance, PMD accesses the RX and TX descriptors directly without any interrupts. With this set of features operator could achieve a boost to the networking performance and can leverage the Layer 2 switch on NIC for virtual machine traffic. The operator can configure advanced features for the VFs on supported NICs like VLAN filtering, mac spoofing, multicast mode, QinQ, insert tag, strip tag etc. This proposed solution will allow operators to configure VFs at a more granular level with all the features available on cards and provide more flexibility to the NFV users.
