Systems are increasingly integrated and networked in supporting the full spectrum of the SAF’s operations. Such systems are usually interconnected within a system of systems comprising advanced sensors; Command, Control, Communication, Computers and Intelligence systems; and shooters. Enabling the system of systems to meet the requirements of SAF operations demands high performance, resilient and secure network infrastructure.

With the growing complexities of such networks, the conventional method of validating their performance and resilience in parts is no longer sufficient. There is a need to ensure that the networks can continue to support system-of-systems operations, even when portions of the networks are unavailable or when traffic load changes according to different operations.

To address these challenges, DSTA developed a framework and methodology that would guide the validation of network infrastructure. This validation process begins from the conceptual design to the implementation phase, covering aspects which include network availability, performance, resilience and safety. Tools such as protocol analysers, network load testers, network modelling and simulations as well as in-house developed tools were used. Through simulations, the network solutions are measured against the design criteria including attributes such as network availability and performance targets.

With network validation, the team is able to identify and address the gaps in the network infrastructure, such as performance bottlenecks. The team can also determine the interdependencies or critical nodes in the network. These efforts have ensured that DSTA is able to deliver networks which can support the Third Generation SAF reliably and securely.
