摘　　要：目前,民航气象业务的常见传输方式是同步数字体系(Synchronous Digital System,SDH)光传输。该方式提高了带宽的利用率,具有一定的优势,但也存在一定的不足。因此,讨论了采用弹性分组环(Resilient Packet Ring,RPR)技术的升级SDH光传输技术在民航气象业务中的应用。该技术强大的保护能力、业务分级、公平算法等特点对于民航气象业务传输来说优势明显。同时,本研究讨论了应用RPR技术后各种民航气象业务的分级传输。对于建设一个满足多业务传输的民航气象通信网络,RPR技术具有很大的潜力。At present,the common transmission mode of civil aviation meteorological service is SDH optical transmission,which improves the utilization of bandwidth and has certain advantages,but this technology also has some shortcomings.This paper discusses the application of RPR technology as an upgrade technology of traditional SDH optical transmission in civil aviation meteorological services.The strong protection ability,service classification and fair algorithm of this technology have strong advantages for civil aviation meteorological service transmission.At the same time,this paper also discusses the hierarchical transmission of various civil aviation meteorological services after the application of RPR technology.RPR technology has great potential for building a civil aviation meteorological communication network to meet multi service transmission.
