*6.2.5 Deterministic network*

"Deterministic network" is a new technology that provides end-to-end network service quality assurance for different users and businesses, and can provide differentiated business services for remote surgery. Its determinism is reflected in three aspects: Firstly, security isolation determinism, achieved through logical or physical segmentation of the network using slicing technology, as well as measures such as user access authorization, data storage filtering, and transmission security checks to achieve security isolation. Secondly, latency and jitter determinism. In the 5G era, many network applications such as remote robotic surgery, autonomous driving, and VR games require end-to-end latency to be controlled within a few milliseconds, and jitter to be controlled within the range of seconds. Thirdly, bandwidth determinism. In the era of traffic, there are higher requirements for upstream and downstream bandwidth. Remote surgery has extremely strict requirements for network latency, jitter, packet loss, redundancy protection, and fast switching. Deterministic network is the key means to achieve these standards. It can cooperate with network slicing and edge computing to sink AI and other technologies to the grassroots level, promote the integration of data and 5G's "cloud-edge-end" functions, fully leverage the advantages and characteristics of 5G independent networking, adjust the network architecture, and meet the overall requirements of remote surgery. Therefore, deterministic network also has good application potential in future remote surgery.
