Digital Twin-Driven Network Architecture for Video Streaming
IEEE Network(2023)
摘要
Digital twin (DT) is revolutionizing the emerging video streaming services
through tailored network management. By integrating diverse advanced
communication technologies, DTs are promised to construct a holistic
virtualized network for better network management performance. To this end, we
develop a DT-driven network architecture for video streaming (DTN4VS) to enable
network virtualization and tailored network management. With the architecture,
various types of DTs can characterize physical entities' status, separate the
network management functions from the network controller, and empower the
functions with emulated data and tailored strategies. To further enhance
network management performance, three potential approaches are proposed, i.e.,
domain data exploitation, performance evaluation, and adaptive DT model update.
We present a case study pertaining to DT-assisted network slicing for short
video streaming, followed by some open research issues for DTN4VS.
