SwarmLayer: A Hybrid P2P Assisted Solution for MPEG-DASH Streaming

The escalating demand for multimedia content requires efficient and scalable distribution solutions for adaptive streaming, particularly MPEG-DASH, in web environments. This paper presents SwarmLayer, a novel hybrid peer-to-peer (P2P) assisted streaming solution designed to enhance web content distribution. SwarmLayer integrates a traditional client-server model with a P2P paradigm, where active users concurrently serve as content distribution nodes by sharing acquired video segments. This approach aims to significantly reduce the load of the origin server, minimize redundant content transmission, and optimize network bandwidth utilization. Implemented as a transparent and non-intrusive intermediate layer between the media player and the content distribution system, SwarmLayer requires no modifications to existing application logic or infrastructure. Its design leverages standard web technologies, including WebRTC for peer connectivity, Service Workers for request interception, and Protocol Buffers for efficient data serialization, along with the MPEG-DASH standard. Experimental evaluations demonstrate substantial server offload, achieving up to a 96% reduction in server traffic, while maintaining seamless playback fluidity across diverse network conditions, including geographically distributed nodes and NAT environments.
