Edge Gaming Proxy Buffering for Low-Latency 5G Retransmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud gaming over wireless networks is prone to packet loss and latency issues, especially with the emergence of 5G networks, which can degrade the gaming experience due to unreliable connections and the need for distant retransmissions from data centers.
Innovation Solution
Deploying a cloud gaming proxy at the edge of the network, proximate to the user, to buffer and retransmit lost packets, minimizing latency and improving video quality by handling retransmissions locally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video games are streamed from distant data centers over wireless networks, then users can access cloud gaming from any location, but packet loss and latency increase due to network unreliability
Solution Approach 1:
The patent introduces edge compute nodes as intermediary components between distant data centers and wireless clients. These edge nodes buffer video packets and perform local retransmissions, mediating the connection to reduce the impact of wireless network unreliability while maintaining location independence
2Reliability
If video packets are retransmitted from distant data centers, then data integrity is maintained, but latency increases due to the distance packets must travel
Solution Approach 1:
The patent segments the retransmission function by separating it from the distant data center and placing it at edge compute nodes closer to the client. This segmentation allows local retransmissions to occur without requiring packets to travel the full distance to and from the data center, reducing latency while maintaining data integrity
3Reliability
If edge compute proxies are deployed to buffer and retransmit packets locally, then latency and packet loss are reduced, but network infrastructure complexity increases
Solution Approach 1:
The edge compute proxy acts as an intermediary that implements buffering and retransmission logic, resolving the contradiction by adding localized functionality without requiring complete system redesign. The proxy integrates into existing network infrastructure at the edge, providing enhanced reliability while maintaining compatibility with current architectures

AI summary
A method is provided, including the following operations: executing a cloud video game in a data center; streaming video generated by the executing cloud video game over a network to a client device that is connected to a base station; identifying an edge compute that is integrated into a computer near the base station, and further responsive to identifying the edge compute, then deploying a cloud gaming proxy to the edge compute; wherein streaming the video includes transmission of the video to the cloud gaming proxy, and wherein the cloud gaming proxy buffers the video for retransmission as needed.
