Ashkan Moharrami, Mohammad Ghasempour, Mohammad Ghanbari

TL;DR
This paper introduces a network-level method to identify and selectively discard less important video packets based on header data, reducing congestion impact without payload inspection.
Contribution
It presents a novel, fast, header-based model for recognizing video packet types at network nodes, enabling effective packet prioritization during congestion.
Findings
Packet type prediction degrades video quality by 0.5-3 dB
7-20 dB improvement over random packet dropping
Method does not require payload inspection
Abstract
High quality (HQ) video services occupy large portions of the total bandwidth and are among the main causes of congestion at network bottlenecks. Since video is resilient to data loss, throwing away less important video packets can ease network congestion with minimal damage to video quality and free up bandwidth for other data flows. Frame type is one of the features that can be used to determine the importance of video packets, but this information is stored in the packet payload. Due to limited processing power of devices in high throughput/speed networks, data encryption and user credibility issues, it is costly for the network to find the frame type of each packet. Therefore, a fast and reliable standalone method to recognize video packet types at network level is desired. This paper proposes a method to model the structure of live video streams in a network node which results in…
