Spying on my Network for a Day: Data Analysis for Networks
summary
Collected one day of home packet captures (about 354 total) producing over 450,000 packets and processed with Wireshark then exported to CSV for visualization in Bokeh inside Jupyter. Analysis pinpoints major bandwidth consumers (YouTube session ~437 MB), shows DHCP broadcasts that reveal a roommate arriving, surfaces background services chewing bandwidth, and suggests automating capture with a Raspberry Pi or using Moloch for large-scale packet indexing and anomaly detection.
