The present paper focuses on evaluating the performance of a complex multi-unit computer networking system. Understanding the performance of such systems is crucial for ensuring efficient operation and identifying areas for improvement. The networking system being analysed consists of four interconnected subsystems. This architecture with subsystems connected in series-parallel is commonly found in real-world computer networks. The present paper considers two types of system failures: degraded failure and total failure. Understanding failure scenarios and their consequences helps in designing resilient systems and developing effective fault-tolerant mechanisms. The study utilises supplementary variables techniques, Laplace transforms, copula and general distribution to analyse and model system's behaviour. The findings can inform the design and optimisation of similar complex networking systems, leading to improved performance, fault tolerance and overall system reliability. The insights gained from this study may also aid in decision-making processes related to network architecture, load balancing strategies and system resilience.
