During 2015 and 2016, many of the leading providers, such as Orange, AT&T, and Telefonica have experienced NFV lab trials, proof of concepts, and some early NFV deployments. Based on these early deployments, NFV is perceived as a complex solution to be deployed with OpenStack. From 6WIND’s experiences, we have seen some lab trials which require many weeks before having an environment that is high performance ready.
Most of the engineering efforts are spent in setting up the nodes because of the constraints related to DPDK powering the NFVi virtual switching: setting up the proper DPDK PCI NICs, configuring the vSwitch VLAN or VXLAN, setting scenarios like DVR, trying to debug with tools like tcpdump, getting a SDN controller into the game, and provisioning the security groups.
Beyond 2016, getting a rapidly-running NFVi environment will become critical to the success of deploying NFV. Fuel can be used to solve such rapid deployments of DPDK-based NFVi.
