OpenSDNCore Heterogeneous/Distributed Infrastructure
The OpenSDNCore underling infrastructure mirrors the essential features of a carrier-grade cloud service provider, including all the relevant elements:
- Real radio networks integration through WiFi and LTE
- Large number of data centers including 3 OpenStack data centers and public cloud integration
- Realistic simplified inter-connection managed or un-managed network, enabling connectivity to the Internet
Two elements are in charge of the management of the infrastructure. The OpenSDNCore Orchestrator acts as a complete infrastructure manager for:
- Data centers - each may include their own Virtual Infrastructure Manager (e.g. OpenStack)
- Inter-data centers network – through the communication with an SDN network controller
- Inter-connection with physical boxes – added as static resources within the infrastructure
- Inter-connection with external systems – added as static logical entities
The SDN Network Controller manages the inter-data center networks, establishes the SDN WANs and adapts to network infrastructure changes.
