Our research paper titled "To Cap or Not to Cap: Bandwidth Capping Effects on Network Interactions and QoE of Competing Short Video Streams," co-authored by our chair in collaboration with researchers from the University of Würzburg and AT&T Labs in the USA, has been accepted to the prestigious 16th ACM Multimedia Systems Conference (MMSys), taking place from March 31st to April 3rd, 2025, in Stellenbosch, South Africa. This paper examines the challenges network operators face in delivering short video services like Instagram Reels, TikTok, and YouTube Shorts. It explores bandwidth capping as a potential solution to manage high-volume pre-loading, which can lead to excessive bandwidth use and unbalanced network resource utilization, especially in competitive bandwidth environments. The findings show that capping reduces download volume (15%–45%) and bandwidth excess (18%–52%) while maintaining nearly the same Quality of Experience (QoE) in most cases.
