Abstract:Network telescopes offer valuable insights into unsolicited internet traffic, but their data is often unwieldy due to its size and the inefficiency of traditional storage formats. This research investigates the use of a columnar data structure as a more efficient alternative to sequential packet storage. A prototype system was developed to convert and analyse PCAPformatted data, with performance assessed through typical analysis tasks. The results highlight notable improvements in aggregation task speed and long-term storage, while revealing shortcomings for optimisation in packet filtering operations.
