【摘要】：宽带城域网是所有IP业务的承载平台,各运营商由于其广阔的市场前景和巨大的商业投资价值,一直非常关注。本论文首先通过分析现有城域网网络结构,从业务发展需求,宽带接入方式等方面认真查找出目前网络所存在的问题。然后根据所发现的问题,制定了合理可行的网络优化解决方案,提出了明确的城域网业务对应QoS等级,在有限带宽基础上更好的满足城域网业务承载需求,达到优化的效果。通过出口带宽扩容,优化网络层次,调整网络结构,优化网络路由等方法,取得了良好的效果,使得网络容量增大,功能性增多,接入层覆盖范围更大,网络性能大大提高。针对汕头城域网的现状,运用该方案对汕头城域网进行了优化扩容改造。该系统在实际运行过程中各项功能均能达到设计要求,其更加灵活、安全的接入特性使本设计系统能更好地适应新应用和新技术不断发展的需要。
[Abstract]:Broadband Metropolitan area Network (man) is the carrier platform for all IP services. Due to its broad market prospects and huge commercial investment value, operators have been very concerned. Firstly, by analyzing the existing metropolitan area network structure, this paper finds out the existing problems from the aspects of service development requirements, broadband access mode and so on. Then, according to the problems found, a reasonable and feasible solution of network optimization is proposed, and a clear QoS level of metropolitan area network service is proposed, which can better meet the demand of man service carrying capacity on the basis of limited bandwidth, and achieve the optimization effect. Through the methods of expanding bandwidth, optimizing network layer, adjusting network structure and optimizing network routing, good results are obtained. The network capacity is increased, the function is increased, the coverage of access layer is larger, and the network performance is greatly improved. According to the present situation of Shantou man, this scheme is used to optimize and transform Shantou man. All the functions of the system can meet the design requirements in the process of practical operation, and it is more flexible. The security access characteristic makes the design system better adapt to the needs of new applications and new technologies.
