摘　　要：随着4K/8K超高清视频在广电行业的广泛应用,传统广电专网在大带宽视频传输服务质量保障上显现出明显不足。对此,分析4K/8K视频传输对广电专网的关键需求,提出广电专网切片的4K/8K视频传输应用方案。该方案涵盖多项关键技术,包括基于FlexE(Flex Ethernet)的4K/8K专用硬切片、基于Slice ID的4K/8K软切片资源隔离、基于随流检测(In-situ Flow Information Telemetry,IFIT)的4K/8K视频质量感知与优化等关键技术。With the widespread application of 4K/8K ultra-high definition video in the cable TV industry,traditional cable TV private networks have shown deficiencies in guaranteeing the service quality of high-bandwidth video transmission.This paper analyzes the key requirements of 4K/8K video transmission on cable TV private networks and proposes a 4K/8K video transmission application scheme based on network slicing,covering key technologies such as Flex Ethernet(FlexE)-based 4K/8K dedicated hard slicing,Slice ID-based 4K/8K soft slicing resource isolation,and In-situ Flow Information Telemetry(IFIT)-based 4K/8K video quality sensing and optimization.
