1.SDN : freedom of ability to create any networks and their overlays 
2.Troll: is an Openflow HW/ASIC switch a SDN equipment? 
How to support any new “what if”? => wait and buy a new switch 
SDN != NFV , but SDN can be made of VNF & NFVI 
SDN – 2 lines
… but SysOps/DevOps virtualizing their networks… 
Where is my network performance?

Physical Switching Limitations 
•Hardware dependent switching (SR-IOV, RDMA, NIC embedded switching) 
•Throughput is limited by PCI Express (50 Gbps) and faces PCI Express and DMA additional latencies 
•Available PCI slots limit the number of chained VNFs 
•At 30 Gbps a single VNF is supported per node!

•Hardware independent virtual switching (NIC driver) 
•Aggregate 500 Gbps bandwidth with low latency

NFV = Network Function Virtualization 
How do I spawn a VM that is an IPsec router, that is a L2TP/DSL (LNS) server, that is a firewall, etc…? Instead of using a physical HW? 
You need network cables … 
Network cables => NFVI – Network Function Virtualization Infrastructure 
It provides interconnect between the physical cables and the virtual network equipments that are spawned 
L2 switch, L3 switch, ACL/Switch 
… and network equipments 
Network Function (equipments) => Virtualized => VNF – Virtual Network Function (vNF) 
vIPsec, vBRAS, vRouter, vFirewall, vXXX 
Openstack provides the framework to spawn Virtual Machines 
Virtual Machines can have multiple virtual network interfaces (vmxnet3, virtio) per VM 
vm1# ip link show | grep virtio | wc –l 
Any VMs with mutiple network interfaces can be any network nodes 
IPsec, Firewall, Proxy 
To some extends, the VMs are the containers of the VNF 
run vIPsec, vFirewall, vProxy 
Openstack/Neutron and Openstack/Nova VIF drivers provides the automations of the provisioning for interconnecting the VMs 
vhost/tuntap, brctl, OVS, L3/routes 
To some extends, this software interconnect of VMs is the NFVI

Instead of using a physical HW? You need network cables … Network cables => NFVI – Network Function Virtualization Infrastructure It provides interconnect between the physical cables and the virtual network equipments that are spawned L2 switch, L3 switch, ACL/Switch … and network equipments Network Function (equipments) => Virtualized => VNF – Virtual Network Function (vNF) vIPsec, vBRAS, vRouter, vFirewall, vXXX Openstack provides the framework to spawn Virtual Machines Virtual Machines can have multiple virtual network interfaces (vmxnet3, virtio) per VM vm1# ip link show | grep virtio | wc –l Any VMs with mutiple network interfaces can be any network nodes IPsec, Firewall, Proxy To some extends, the VMs are the containers of the VNF run vIPsec, vFirewall, vProxy Openstack/Neutron and Openstack/Nova VIF drivers provides the automations of the provisioning for interconnecting the VMs vhost/tuntap, brctl, OVS, L3/routes To some extends, this software interconnect of VMs is the NFVI Introduction to NFV & and why Openstack – 1 slide
