ARCHITECTURE

FEDERICA is a multidimensional network able to provide on slicing principles, and using dedicated lines for connecting Physical Nodes (PN). Within boundaries of each PN multiple instances of Virtual Nodes (VN) may be created, including virtual machines based on various operating systems or emulating L2/L3 network equipment.

Each virtual machine acts independently, and can run different applications at the same time. Connections between VNs is made via Virtual Paths (VP) created over the physical networking infrastructure, using techniques such as tunnelling.

All VNs dedicated to the same purpose, along with the VPs connecting them together, represent one independent virtual infrastructure called a slice. A slice contains all distributed networking resources (routers, switches, etc.) and also end point virtual machines. All of these resources are seen by the end users as physical infrastructure and the virtualization layer is hidden from them. There is no theoretical limit to number of slices that can be created, and there is no limit on number of applications (of any type) running inside each slice.

FEDERICA multidimensional architecture

The FEDERICA architecture consists of three parts:

• At thelowest level, is a fixed physical infrastructure connecting Physical Nodes (PN) (Juniper MX/EX boxes and V-nodes) and to users outside the FEDERICA Network.
• Above the physical infrastructure is a virtual layer where VNs are created and connected with VPs according to user requirements.
• The third layer includes slices provided to users, which are seen as physical infrastructure.
