  2. Network Virtualization Overlays Promise • Compute system and physical networking decoupled • Both systems and networking exist in a virtual environment • Virtual networks are built on a common infrastructure with: • Traffic isolation among one another, independent address space in each • VM placement and move from one server to another without physical network limitation VM VM VM VM VM VM VN2 VN1 VN3 Virtual Physical VM VM VM VM VM VM vSwitch vSwitch vSwitch IETF NVO3 Vancouver draft-mity-nvo3-use-case-01

  3. NVO3 Use Cases I. Virtual Networks in One Data Center • Provide communications among the VMs in a closed use group • Use for DC internal applications II. Interconnection between DC virtual network and external user • One virtual network method in DC and WAN • VN and VPN interconnection at DC Gateway • Connecting a DC virtual network via Internet DC1 DC2 VM VM VM VM VM VM VM VN3 VN2 DC VM VN1 VM GW GW WAN Internet VPN (1) (2) (3) IETF NVO3 Vancouver draft-mity-nvo3-use-case-01

  4. NVO3 Use Cases Cont’ III. DC applications using virtual networks • Multi virtual networks to interconnect a large amount of VMs in DCs • Individual VNs may be L2 or L3 • May contain multiple topologies • Gateway interconnect VNs • Virtual Data Center • Network services per virtual network • Client manages applications running in vDC • DC operators manage vDC Details are illustrated and described in the draft Network Service: Firewall/Security Monitoring Load Balancer Bridging/routing VM DC1 VM DC2 VM VM VM VM vDC VM L2VN L2VN DC GW GW GW WAN L3VN Internet IETF NVO3 Vancouver draft-mity-nvo3-use-case-01

  5. NVO3 Applicability • NVO3 differs from traditional overlay technologies in • A virtual network connects to and is aware of VMs • Virtual network edge and VMs resides on the same hardware • VN and VM are managed by the same orchestration • NVO3 brings the ability of building IT applications in a true virtual environment • Construct IT applications without worry about physical network limitations, enable IT new applications • Speed up in building vDC, private or public cloud applications for various customers • NVO3 has to address how to communicate between a virtual environment to a physical environment • Many traditional DCs exist today and not disappear soon • A large of DC applications serve to Internet or corporation users IETF NVO3 Vancouver draft-mity-nvo3-use-case-01

  6. Next Step • Welcome comments and suggestions • Authors request adopting the draft as WG draft IETF NVO3 Vancouver draft-mity-nvo3-use-case-01
