OpenStack Cloud Networking

OpenStack cloud orchestration promises scalable, cost-effective private/hybrid clouds. However, OpenStack networking using Open vSwitch or Contrail vRouter Software imposes a significant CPU consumption and VM performance tax.


OpenStack networking using Neutron with the Open vSwitch (OVS) plug-in is the most used cloud network setup in production. Agilio® SmartNICs with Agilio software provide complete integration with OpenStack, preserving all automation features for VM provisioning, startup and shutdown while accelerating networking and security features as well as data delivery to VMs. Networking services are enabled with significant acceleration, freeing up CPU cores to improve server productivity and extending the applicability of hardware-accelerated OpenStack networking to a significantly larger set of cloud, NFV and SDN-based applications.


Agilio SmartNICs with Agilio software implement the entire compute node networking datapath in hardware. Packets are delivered to VMs using SR-IOV, DPDK and Express Virtio (XVIO). The Netronome solution enables OpenStack to preserve automation of VM provisioning, startup, and shutdown while accelerating sophisticated networking and security services to VMs.
