Experience with DPDK Troubleshooting

Getting near real-time performance for VNF applications requires designing the application carefully and profiling its performance under realistic conditions. OpenStack has developed many functionalities that helps in this, such as CPU and PCI topology awareness and pinning the virtual machines to dedicated cores. The host networking stack, in turn, has been optimized with features such as accelerated virtual switches and DPDK.This presentation gives an update of using DPDK in real VNF tests and
