aerOS continuum architecture

Resource-aware orchestration across network and compute domains.

The aerOS-based continuum supports transparent service deployment and dynamic migration across the two domains, using current resource availability, SLA constraints and service-specific requirements as orchestration inputs.

01 / Unified execution layer

A cohesive resource pool

Heterogeneous computing and networking resources are abstracted into a common execution environment, simplifying deployment across distributed infrastructure.

02 / AI-enabled decision layer

Global placement decisions

Service placement is optimized from a continuum-wide view of resources, policies, SLAs and application requirements.

03 / Enforcement layer

Reliable execution

Selected placement decisions are enforced on the chosen infrastructure, supporting automated deployment and migration across domains.

The continuum is designed to scale as new domains and resources are integrated, extending the orchestration scope without changing the high-level operating model.
Two 5G Standalone environments

Telecom-grade scale and flexible research configurations.

Network 01

ATH 5G SA Core + Ericsson infrastructure

The ATH 5G Core is deployed at OTE Academy and controls Ericsson infrastructure across both campuses.

Two Ericsson BBUs, one at each campus
Three Ericsson RRU/RAN units per BBU
Six indoor/outdoor cells in total
Additional mmWave RAN equipment at OTE
Network 02

Amarisoft RAN + flexible 5G SA Core options

At NCSR Demokritos, the second environment combines Amarisoft RAN with selectable core configurations and software-based RAN tools.

Amarisoft and Open5GS core options
NEF, NWDAF and CAPIF openness where available
Native AI programmability options
UERANSIM and srsRAN, including ZeroMQ-based setups
Additional experimental systems

Open and portable infrastructure for specialized trials.

OpenAirInterface

OAI OAIBOX

A complete 5G Core and RAN-oriented research system using Split 8 architecture, intended for flexible open-source experimentation and external component integration.

Portable deployment

Raspberry Pi–based 5G system

A compact platform with a containerized 5G Core for rapid setup in constrained, temporary or remote environments, with the ability to pair with different external RAN units.

aerOS + B5G convergence

Containerized network functions become part of the continuum.

Containerized 5G network functions, such as an Open5GS UPF, can benefit from aerOS orchestration for policy-driven deployment and migration based on application-specific or user-centric needs.

Monitoring flow

From resource metrics to real-time visualization.

The monitoring stack supports repeatable experiments by collecting infrastructure telemetry, surfacing alarms and visualizing system behavior during trials.

Prometheus-based framework

Node Exporters → resource and host metrics
Prometheus server → time-series storage and queries
Alertmanager → alarms and notifications
Grafana → real-time visualization and dashboards
