Evolving Mobile Cloud Gaming with 5G Standalone Network Telemetry
CoRR(2024)
摘要
Mobile cloud gaming places the simultaneous demands of high capacity and low
latency on the wireless network, demands that Private and Metropolitan-Area
Standalone 5G networks are poised to meet. However, lacking introspection into
the 5G Radio Access Network (RAN), cloud gaming servers are ill-poised to cope
with the vagaries of the wireless last hop to a mobile client, while 5G network
operators run mostly closed networks, limiting their potential for co-design
with the wider internet and user applications. This paper presents Telesa, a
passive, incrementally-deployable, and independently-deployable Standalone 5G
network telemetry system that streams fine-grained RAN capacity, latency, and
retransmission information to application servers to enable better millisecond
scale, application-level decisions on offered load and bit rate adaptation than
end-to-end latency measurements or end-to-end packet losses currently permit.
We design, implement, and evaluate a Telesa telemetry-enhanced game streaming
platform, demonstrating exact congestion-control that can better adapt game
video bitrate while simultaneously controlling end-to-end latency, thus
maximizing game quality of experience. Our experimental evaluation on a
production 5G Standalone network demonstrates a 178-249
improvement versus two state-of-the-art cloud gaming applications.
