In order to demonstrate the breakthrough innovations we are proposing in the framework of the 5G NORMA project, we carefully defined a set of demonstrators that showcase very heterogeneous Key Performance Indicators (KPIs) that can benefit from the introduction of the 5G NORMA concepts.
More specifically, we decided to develop the following four demonstrators: Native Multi-service Architecture (Demo #1), Service-aware QoE/QoS Control and Orchestration (Demo #2), the Secured Multi-Tenancy Virtual Network Resources Provisioning via V-AAA (Demo #3) and the Online Interactive 5G NORMA Business Cases Evaluation Tool (Demo #4).

Demo #1. Native Multi-service Architecture
The first demonstrator displays how the Software Defined Mobile network Controller (SDMC) concept can be introduced into the state of the art RAN stack. Tight hardware–software integration, simplified by a well-defined API capable of abstracting the complexity introduced by vendor-dependent specificity was achieved. The demonstrator shows how service-aware tailoring of Network Functions (NF) enhances the Quality of Experience (QoE) perceived by users. Two partners are involved in this demo: Azcom and Nomor.
This joint demo (Hardware & Software) presents a proof of concept for the (de)composition of NFs, which is one of the architectural key principles in 5G NORMA. It demonstrates how certain network functions (the routing components) could be decomposed and executed directly on the System on Chip base station hardware in order to reduce latency and increase throughput. It also incorporates an SDMC-like software component, which is one of the main building blocks defined in the 5G NORMA architecture. The adjustment in throughput and latency is computed on that SDMC component, which send commands towards the eNB using a specific communication protocol to (re-)configure the placement of the network functions.
This demo was shown in several relevant international events (MWC-2016/17, EuCNC’16, ICC’16, among others). The following figure shows the most recent deployment at the EuCNC 2017:
Demo #2. Service-aware QoE/QoS Control and Orchestration
This demonstrator leverages on open-source tools to showcase an innovative solution in the field of network control and orchestration. The service-aware orchestration, in particular, adapts the network function placement according to the requested KPIs. This demonstrator was integrated by University “Carlos III” of Madrid (UC3M) and Atos.
The demo is mainly focused on showing a proof of concept focused on service aware QoS/QoE control, as well as demonstrating how to use service orchestration capabilities based on NFV. Main topics here are NFs Containerization, Virtualized Network Functions (VNFs), Orchestration and implementation of QoS/QoE Mechanisms. The Management and Orchestration modules used for this demo are basically a specific implementation of the ETSI NFV MANO framework, which basically corresponds with the 5G NORMA architectural blocks for its Management and Orchestration layer.
Demo #3. Secured Multi-Tenancy Virtual Network Resources Provisioning via V-AAA
The third demonstrator focus on novel mechanisms for the Authentication Authorisation Accounting functionalities. Based on open source software and implemented using commodity hardware, this demonstrator shows the feasibility of reproducible experiments in multitenant environment. This demonstrator was developed by the King’s College of London (KCL).
This demo provides a simple infrastructure for conducting small-scale repeatable experiments of the 5G NORMA architecture, especially those involving secure multi-tenancy and multi-tenant data isolation on the access network (edge cloud). The testbed is based on 1) commodity hardware, i.e., Raspberry Pi, home Wi-Fi router and switch and 2) open source software, i.e., Ryu controller, Open Authentication protocol, CouchDB and OVS, which has been configured and extended to provide a hierarchical and distributed database cluster for tenant isolation and replication of the Tenant data (e.g. billing data, Tenant service logs).
Demo #4. Online Interactive 5G NORMA Business Cases Evaluation Tool
Finally, the fourth demonstrator focus on the evaluation of business aspects of 5G NORMA through a web-based platform. This demonstrator was developed by Real Wireless (RW).
The demo demonstrates the key outputs and sensitivities of the evaluation cases selected as part of the overall project evaluation framework (Deliverable D2.3). The tool shows the economic feasibility of the 5G NORMA architecture by looking at three different evaluation cases:
- Baseline evaluation case – comparison of 5G NORMA with evolved legacy (LTE-A Pro) networks for MBB services.
- Multi-tenant evaluation case – comparison of single and multi-operator networks for MBB services.
- Multi-service evaluation case – comparison of single and multi-service networks covering MBB, V2X and Critical Machine Type Communication (uMTC) services.
