A BIER Multicast-based Low Latency Live Streaming System
Qing Jun Pan, Qimiao Zeng, Yirong Zhuang, Ge Chen · 2023
As 5G services continue to rapidly develop, operators are experiencing an increasing proportion of network traffic usage devoted to streaming content. Streaming media is particularly suited for transmission in multicast networks. This paper presents a low-latency live streaming system that leverages Bit Index Explicit Replication (BIER) multicast. Furthermore, we complete end-to-end push-pull stream verification within a BIER multicast laboratory to demonstrate the effectiveness of our design. To serve as a case study for this system, we deployed it within an enterprise by connecting internet streaming media to the system. This deployment resulted in significant reduction of resource consumption during internal meetings and training sessions, which were previously using external bandwidth. Additionally, this approach allowed for unified management of streaming media gateways across multiple branches of the enterprise, even those scattered across different geographic regions, optimizing resource allocation. Thus, the system now supports daily operations of internal meetings and training sessions.
