【摘要】 随着人们对宽带数据业务需求的不断提高,现代通信发展的重点已逐渐从以传统话音业务为代表的窄带业务向多业务、高速率的宽带业务转变。作为接入网与核心网之间的传递平台,城域网扮演着越来越重要的角色,但目前城域网络的建设又面临着业务复杂、资源配置不均衡等问题。因此,多业务支持与资源统一管理将成为城域级传输设备的发展趋势。本文主要研究了城域多业务传输平台的系统设计、硬件实现与网络管理方案。首先针对城域网的特点,通过需求分析对平台的系统结构进行了设计,然后依照系统结构将平台划分为若干模块,并对硬件设计与实现进行了具体的研究,内容涉及原理图设计、PCB制作、信号完整性测试等方面。在完成内部模块设计的基础上,本文还从安全性及可靠性的角度出发,对平台成品整机的结构进行了设计,主要包括电磁兼容性设计和热设计两部分。同时,考虑到平台资源统一管理的需求,本文介绍了平台网络管理系统的组织结构与应用。最后,提出了城域多业务传输的进一步研究方向。作为一套系统解决方案,本文所研究的平台不仅实现了对各种不同协议和速率业务进行传输的功能,同时还提供了光路保护、光放大、色散补偿等光传输线路端的可靠性保证,并支持按用户不同需求进行定制,在系统结构设计中充分考虑到未来可能出现的新业务,便于升级。其特点在于通过一个统一的平台,实现对各种业务与资源进行配置管理,在提高可靠性的同时,降低了运维成本,为用户带来一个高效,低成本及高可靠性的传输网络。更多还原

【Abstract】 With a rising demand for data service, modern telecommunication is moving its emphasis from traditional narrow-band service (e.g. voice transmission) to broad-band service (multi-service, high speed). Connecting Access Network and Core Network, metropolitan area network (MAN) is becoming more and more important. However, the development of MAN is facing challenges, such as complex service, disproportion source configuration, and so on. Therefore, multi-service and sourcing management will be the trend in the development of metro transmission equipment.This paper proposed a design of the metro multi-service transmission platform, including system structure, hardware implementation, and network management. First, according to the required features of MAN, the system structure of the platform is given. Secondly, the system is divided into several sub-modules by function, and a detailed research which realized each sub-module is made, including schematic design, PCB development, signal integrity, etc. Considering the requirement on security and reliability, a framework design about electro magnetic compatibility and thermal system is also given. Then the structure and application of the system’s network management is introduced. Finally, the further research direction of metro multi-service transmission system is suggested.As a system solution, the platform proposed in this paper not only offers multi-protocol and multi-rate service, but also integrates other functions to improve the reliability, such as optical routing protection, optical amplify, dispersion compensation, etc. The users can customize the configuration according to their requirement also. And the system design also allows easy updating to fit new service in the future. In conclusion, this system offers a unified platform, which can transmit many different kinds of traffic, and can manage the source configuration as well. Upon that, we achieved an application of optimization , an efficient, low cost and high reliability transmission network.更多还原
