Examples of Future Tactical Communication Requirements

cellular network

V/UHF tacticalradio network

V/UHF tacticalradio network

satellite link

IP based communication

Voice communication (VoIP, analog)

Heterogeneous media capabilities and reliabilities in a non-cooperative environment

Rapidly changing network topologies

Motivation: Simulation-, Test and Reference Environment

Challenges of integrated networks: Complexity

System of systems

Heterogeneous networks with various transmission technologies

Mobile and dynamically changing non-cooperative environment (low bitrates, occasional high latencies, disruptions)

Risks:

No or limited interoperability in between systems and components

Limited end-to-end performance of the interconnected heterogeneous communication technologies

Limited performance of the different communication technologies themselves

High financial risk/ effort in case of a system’s replacement within the system-of-systems

Requirement for comprehensive and extensive system testing BEFORE, DURING and AFTER fielding

SumO – Simulation, Test and Reference Environment for Heterogeneous Networks

Tests of

Individual devices in a system’s context

Systems of a single type of devices in a system-of-systems context

the overall system summing up to hundreds of radio, networking, and application devices of different types

Integration of multiple technology-specific labs via one over-all framework providing modularity and extensibility

Utilizing virtualization of devices jointly with hardware-in-the-loop

Synchronized, rule-based triggering of DUTs and state recording throughout the labs integrated in the framework

Benefits of the Simulation-, Test and Reference Environment

Support during analysis, design and configuration of the network of technically heterogeneous networks

Acceptance tests of components, profiles and applications

Integration and interoperability tests prior to the roll-out of updates, upgrades, and replacing/new systems to the field as part of projects’ Change and Release Management Processes

Support of a Configuration Management Database

Non-proprietary component and system tests for benchmarking within the specifications or requirements

Unbiased, objectively comparable and reproducible test results

Validation of new configurations within the system-of-systems

Fault analysis under realistic emulations/ simulations and reproducible environmental conditions

Script-based test automation and evaluation

Conclusions and Outlook

Before SumO, there was no means of reproducible testing of multiple interacting devices in large, heterogeneous dimensions.

Introducing virtualization of communication devices for scalability reasons is both technically and economically as well as time efficient.

The SumO framework will provide a repository

of all relevant parameters and

technical interdependent capabilities and configurations

of all tested devices

that can be utilized as blueprints for initial mission configurations.

Current status: feasibility study to provide full proof-of-concept within the next 12 months.

SumO applies to D-LBO and TEN for enabling the technical validation and verification throughout the programs’ systems’ life cycles.
