摘　　要：IP over SDH是将IP网络技术直接建立在SDH平台上,减少了网络分层的中间冗余部分和各层的功能重叠,是一种最直接、简单、经济的IP网络体系结构,不仅提高了带宽利用率,而且大大节约了运营成本。文章将该项技术纳入如东地区电力信息网的组网方案,并根据IP over SDH的技术原理,结合如东地区实际,讨论了方案设计的一些细节及应用优势。IP over SDH is that IP network technique is setup on SDH platform directly, it can reduce the middle redundant network layers and overlap function of layers, it is a kind of the most direct, simple and economic IP network system structure, it can not only improve the utilization of bandwidth, but also save the operation cost greatly. The constructing scheme of electric information network in Rudong County has adopted this technique. According to the technological principle of IP over SDH, combining with the reality of Rudong area, this article discusses some concevtual design and application advantage.
