Project Description:

The MDO is an E2E service orchestrator that builds product-facing production services from the services of the connected domains. Each domain provides domain services (e.g. copper access) and these are combined by the MDO into aggregated production services that can be used in product definitions. DNA project will deliver the MDO system and support a series of use cases (e.g. 5G Slicing for TDG or Premium Internet Underlay (PIU) for the Solution Business Tribe). Benefits will ramp up with the realization of each release. By modularizing and implementing additional products further benefits can be achieved.​
DNA (Drive Network Automation) is an initiative which unites several projects which are building a technology-savvy platform used across different instances and domains intended for automation and orchestration of network elements, services and network functions. MDO stands for Multi-Domain Orchestrator - the platform that orchestrates networks across various domains.
