The document discusses NFV (Network Functions Virtualization) and SDN (Software Defined Networking). It covers NFVI (NFV Infrastructure), VNFs (Virtual Network Functions), SDN control and orchestration, and combining NFV and SDN. It provides examples of virtual network functions like vRouter, vFW, vADC that can replace physical network appliances. It also discusses the OpenStack platform, Intel DPDK, Vyatta, and SDN controllers like OpenDaylight and Brocade and how they improve performance and efficiency for NFV.

• Three networks – Public, SNET and Isolated
• Isolated (Private) networks
• Broadcast and Multicast on Isolated networks
• Attach / Detach Networks
• Shared IP on Isolated networks
• Additional IPs on PublicNet
• L3 Router, VPN and Firewall: (Brocade Vyatta vRouter)
• Routes on Isolated networks
• Floating IP
• L4-L7 Services
