BUSINESS DRIVER

This section describes Business Drivers needs.

Executive Summary - This is the first attempt by using ONAP to realize cross carrier communication. In this use case, we provide an end to end cross operators international VPN service which includes features like cross operator, cross domain(different OTN domains) and cross layer(Layer 2 and Layer 3) by taking advantage of the strong orchestration ability of ONAP.

Business Impact - This use case meets the demands of the following aspects:

  • Real-time resource update.
  • OTN equipment operation and scheduling for different vendors.
  • Multi-constrained end-to-end route computation.
  • Multi-domain end-to-end service providing.
  • Multi-domain network end-to-end survivability.
  • Supply SMB companies with VPN service on demand, instantly, flexibly
  • Deploy VPN service by overlay mode , untouch carrier network
  • “One-click open”and “One-stop”, automatically deploy enterprise VPN service
  • Self-service order for client-side CPE, self-delivery client-side CPE
  • Provide various value-added service on client-side SD-CPE and cloud side

Business Markets - For  enterprise customers who want to set up VPNs among multiple sites. Specifically for Enterprise having branches overseas.

Funding/Financial Impacts -

  • Large time saving and labor saving by providing automatic service scheduling and resource maintenance.
  • Provide cross carrier connection. Service provisioning is not restrict within one ONAP any more.

Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.
