purpose
Purpose

Outline the high level requirements for virtual networks automatic provisioning in NVO3.

typical vn provisioning procedures
Typical VN Provisioning Procedures
  • VN requirements collection
  • Deploy
    • Mapping
    • Delivering/Configuration command
    • Execution
  • Running
  • Reporting
management initiated vn auto provisioning description
Management Initiated VN Auto-Provisioning: Description
  • VN requirements collection
  • Deploying
    • Mapping
    • Delivering/Configuration command
      • Create VM
      • Configure VM(’s vNIC)
      • Configure NVE
      • Optional, other configurations
    • Execution
  • Running
  • Reporting
management initiated vn auto provisioning requirements
Management Initiated VN Auto-Provisioning: Requirements
  • Req-1: Standard NVA-NVE/GW management interfaces, includes interface protocol and related parameters
  • Req-2: Standard NVA-Hypervisor/VM Orchestration System management interfaces, includes interface protocol and related parameters
  • Req-3: Optional, automatic routing protocol configuration
  • Detailed information, TBD
vm initiated vn auto provisioning description
VM Initiated VN Auto-Provisioning: Description
  • VN requirements collection
  • Deploying
    • Mapping
    • Delivering/Configuration commands
      • Create VM
      • VM auto-discover NVE
      • VM auto-join NVE
      • VM auto-configuration
      • NVE auto-configuration (triggered by VM)
        • Create VRF; and/or Add New Entry; or do nothing
      • Optional, other configurations
    • Execution
  • Running
  • Reporting

VM-NVE Protocol, NVE-NVA supp.

NVE-NVA

vm initiated vn auto provisioning requirements
VM Initiated VN Auto-Provisioning: Requirements
  • Req-1: NVE auto-discovery protocol, be used to discover NVE automatically and further automatic join NVE and trigger NVE to auto-configure the related VN
  • Req-2: NVE auto-discovery protocol support and efficiently deliver the related parameters, include MAC address, IP address, VN-ID, Session-ID, etc.
  • Req-3: VM authentication to VN by using the existing protocols such as EAP or IEEE802.1x, etc
  • Req-4: NVE supports automatic execution of create VRF command and configuration
  • Req-5: Optional, automatic routing protocol configuration
  • Detailed information, TBD
conclusion
Conclusion
  • Management Initiated(/Administrator configuration/operation simulation) VN Auto-Provisioning mechanism needs lots of standardization works.
  • VM Initiated VN Auto-Provisioning mechanism by defining a new light-weighted VM-NVE protocol to show the possibility to realize VN auto-provisioning.
