摘要
Abstract
To address the issues of uncertain latency and low resource utilization when satellite optical networks carry fine-grained services,an elastic transmission technology based on optical service unit(OSU)for inter-satellite laser links(OISL-OSU)is proposed.This technology achieves flexible service slicing through OSU mapping and multiplexing,designs RS(255,223)coding to enhance channel reliability,and verifies performance through simulations and comparisons with existing schemes.Results show that for frame lengths ranging from 68 to 1 522 bytes,single-node latency is reduced by 44.99%～58.26%,jitter suppression reaches 12.50%～62.50%,and throughput for small frames is significantly improved.This effectively enhances the hard pipe isolation and deterministic transmission capabilities of satellite optical links.关键词
