基于SDH的多业务传送平台的研究
|
摘要
多业务传送平台MSTP(Multiple Service Transport Platform)解决了SDH(Synchronous Digital Hierarchy)处理数据弱的课题,实现了以太网、ATM(Asynchronous Transfer Mode)、RPR(Resilient Packet Ring)等信号到SDH的映射和传输,对网络升级或构建城域网有着重要的实际意义。
基于与实现MSTP密切相关的SDH技术的讨论,重点研究了实现MSTP的几种关键技术。在GFP(Generic Framing Procedure)封装技术中讨论了GFP的帧格式和定帧方法、成帧映射和透明映射的两种工作方式。在级联技术中阐述了连续级联和虚级联的定义及两者的区别和虚级联成员组的构成图。在RPR技术中讨论了RPR的双纤反向拓扑图和帧结构及其含义,分析了RPR的物理层及其支持的A、B、C三种业务类型,详细讨论了RPR的队列技术、全局公平算法及两种业务保护方式,讨论了RPR的拓扑发现功能和管理功能。
给出了实现MSTP的基本原理和方法。MSTP在实现时包括SDH部分和数据部分,在SDH部分重点讨论了实现SDH传统功能的原理框图和实现原理的功能模块;数据部分主要讨论了以太网映射到SDH的原理框图和相应的功能模块。
MSTP设备的开发成功实现了数据网和语音网的统一,方便运营商规划网络,有效利用网络资源。
MSTP (Multiple Service Transport Platform) makes up the shortcoming of data processing of SDH (Synchronous Digital Hierarchy), and implements Ethernet、ATM(Asynchronous Transfer Mode)、and RPR(Resilient Packet Ring) which implement the mapping and transmitting signals to virtual container. It is of great significance for network upgrading or MAN construction.
Based on discussion of SDH, several critical technologies for MSTP are under investigation. Frame format and frame location method are discussed in GFP (Generic Framing Procedure) encapsulation technology, and framed mapping and transparent mapping are also discussed. In concatenation technology, the definition and differences of consecutive concatenation and virtual concatenation are presented and the constitution graphic for virtual concatenation member group is depicted. The two ring adverse topology and meaning of RPR is discussed. The physical layer and A, B, C types of service types supported by it is analyzed. The queuing technology of RPR, Global fairness algorithm, two types of service protection is detailed discussed, topology discovery and management functions of RPR are discussed.
The basic principals and methods of MSTP are provided. MSTP consists of SDH part and data part. In SDH part, SDH framework graphic and function modules that implement traditional functions are discussed.
The success of MSTP integrates the data network with voice network and facilitates the lay out of network of Internet Service Provider and thus make full of network resource.
