VIBeS project addresses a system architecture where NFV-PEP agents are integrated in a converged satellite-terrestrial system. The figure below depicts the general deployment model tailored to reproduce target 5G services and architectures in a PoC testbed.
VIBeS testbed can be split into three NFV Infrastructure Points of Presence (NFVI-PoP) with dedicated hardware (network, computing and storage resources).
The NFV-PEP-PoP hosts a chain of orchestrated VNFs to improve target services provision over satellite-integrated communication scenarios. This component is under control of a Satellite Virtual Service Operator (SVSO).
The Satellite Baseband Infrastructure-PoP provides the emulated physical satellite infrastructure for forward and return links. This component includes all the non-virtualized elements under the control of a Satellite Network Operator (SNO).
The terrestrial network PoP is composed of three macro-blocks: (1) a vEPC for mobile access through 4G radio fronthaul; (2) a core network managing connections with public Internet or local IP services: (3) a re-configurable network sub-layer allowing flexible and reconfigurable PoC configuration.
In addition to the above NFVI, a WiFi access point is included with the primary scope to “simulate” a direct access to satellite access, through NFV-PEP, bypassing the EPC in accordance with requirements of a subset of use-cases.
