Core Concepts
Digital twins can enable holistic network virtualization and tailored network management to satisfy the diverse requirements of emerging video streaming services, such as intelligent short video, extreme immersive VR, and holographic video.
Abstract
The article proposes a Digital Twin-Driven Network Architecture for Video Streaming (DTN4VS) to enable efficient network management for emerging video streaming services.
Key highlights:
Emerging video streaming services, including intelligent short video, extreme immersive VR, and holographic video, demand tailored network management to satisfy personalized requirements.
Advanced communication technologies, such as eMBB-Plus, native AI, sensing, network slicing, and digital twins (DTs), can be integrated to satisfy the requirements of video streaming services.
The DTN4VS framework consists of three domains: physical, slice, and DT. DTs, including user DTs (UDTs), infrastructure DTs (IDTs), and slice DTs (SDTs), can characterize the network from user, operation, and service perspectives, respectively.
DTs can provide distilled user information, emulated environment, and tailored network management strategies to realize efficient network management.
Challenges and potential solutions are discussed, including efficient data abstraction, comprehensive performance evaluation, and adaptive DT model update.
A case study on DT-assisted network slicing for short video streaming is presented, demonstrating the superior performance of the proposed approach.
Stats
The global video streaming market size was valued at $89 billion in 2022, and is expected to grow at a compound annual growth rate of 21.5% until 2030.
Intelligent short video streaming emphasizes interaction with users, triggered by swipe and rotation behaviors.
Extreme immersive VR streaming demands ultra-low latency of 5-20 ms.
Holographic video streaming requires end-to-end delay lower than 5 ms for 6-DoF movement.
