Network analytics complements testing and modeling activities during not only the design phase of a network or system, but also the implementation and subsequent production and operation phases. To ensure that network and system solutions deliver their required service quality, a range of testing and analytics capabilities and practices are required to model, measure, and evaluate the effectiveness of the solutions over their life cycles. Our newly added topics of interest include network analytics infrastructure, custom analytics solutions for planning, traffic management and overall improvement of network infrastructure and operations, network performance monitoring and diagnostics, predictive network analytics to help detect network and application issues, and analytic tools for troubleshooting and identifying root causes.
