求英语达人帮忙翻译一段话,中译英
随着信息社会的到来,人们希望现代信息传输网络能快速、经济、有效地提供各种电路和业务,而原有网络技术由于其业务的单调性,扩展的复杂性,带宽的局限性,仅在原有框架内修改或完善已无济于事, 此时SDH的产生并凭借其众多特性,使其在广域网领域和专用网领域得到了巨大的发展.SDH(Synchronous Digital Hierarchy)帧结构中安排了丰富的开销字节用于网络的运行、管理和维护.概括起来,这些开销字节主要包括段开销（SOH）和通道开销（POH）两类.段开销又可分为再生段开销（RSOH）和复用段开销（MSOH）.通道开销也可再分为高阶通道开销和低阶通道开销,分别用于断层和通道层的管理和维护.
!不要翻译软件直接译过来的,.翻译得好会追加一倍以上分数.谢谢啊

With information society's coming,people hope modern information transmission network to provide various circuit and business quickly,economically and effectively,as the original network technology for its monotonic business and complex extension,the bandwidth limitations,it's already useless to modify or perfect in original framework,at the same time,the production of SDH and relies on its many characteristics,it come at a huge development in the WAN fields and Private network areas.SDH (Digital Synchronous Hierarchy) frame structure arranged for the rich of network overhead bytes for operation,management and maintenance.Generally speaking,these spending bytes mainly includes section overhead(SOH) and Path Overhead (POH).SOH can divide into Regenerator Section Overhead (RSOH) and Multiplex Section OverHead (MSOH),Path Overhead can also be further divided into Higher order Path Overhead andLower order Path Overhead,respectively applied for the management and maintenance of faults and Path Layer.
供楼主参考,满意请加分.
再问： 谢谢，追问一句，题目《SDH开销字节功能分析》--这个翻译成《A Analysis About SDH Overhead Bytes’ Function》，，这样合适不？看看你的翻译是怎样的
再答： SDH Overhead Byte Function Analysis 好像可以直接這樣翻譯。
