Exploring the Usability of Network Simulation Tools
Abstract:
Current network simulation tools provide advanced simulation solutions that cut down on costs and provide a simpler way to test different scenarios and mitigate risks before actual deployment. However, many of these tools still possess several shortcomings that hinder their widespread adoption and usability. These limitations encompass their static nature, which lacks the capacity to accommodate dynamic scenarios. Additionally, these tools struggle to handle changing conditions like low bandwidth scenarios, a common occurrence in diverse contexts such as defence applications. Moreover, the current tools lack essential usability features and adaptability, resulting in suboptimal user experiences and interactions. Our study explores professional’s experiences of using network simulation tools, to better understand their current limitations and future potential. Research in the field details many of the technical limitations of existing network simulation tools that hinder their effectiveness in replicating real-world network scenarios. However, usability issues that pose a significant barrier, impacting user-friendliness and productivity, are not fully explored. In response to these challenges, our study employs a mixed-methods approach to collecting data. By analysing responses from a questionnaire and a design workshop, it uncovers the critical technical and usability features, needs, and challenges perceived by professionals in this field.
Our study provides a list of essential features for network simulation tool enhancement, underpinned by the feedback and experiences of participants. These features represent a way to refine these tools, streamline their user interfaces, and align their capabilities with the evolving landscape of network simulation tools. This study improves our understanding of the challenges faced by network simulation tools, particularly when applied within a day-to-day working experience with clients. It synthesises practical recommendations for tool enhancement and usability improvements, offering an initial blueprint for future developments.
