OpenDaylight Summit 2015

There is an ever-increasing pressure on networks to perform and manage greater workloads with increase in cloud, mobility, and Internet of Things. Data Plane Development Kit (DPDK) is an open source project comprising a set of libraries and drivers for fast packet processing. There is an effort to accelerate OpenVSwitch (OVS) using DPDK. In order for OpenStack orchestrator to make use of DPDK acceleration, ODL needs to find the capabilities of OVS and pass the required port type information to OpenStack. ODL will take in commands from OpenStack for DPDK accelerated vSwitch and pass it to OVS. This presentation talks about what hooks are provided in ODL to enable support of DPDK accelerated vSwitch. The talk will also provide an overview of implementation of the emerging Service Function Chaining (SFC) using DPDK. The presentation will include our experiences in the implementation of the SFC classifier, SFF and illustrative SFs, and the VxLAN-GPE+NSH processing using the Open Virtual Switch (OVS) with DPDK-netdev capability. We intend to share preliminary performance results and future work on hardware offloads.
