分析的

Statistics analysis is becoming more arduous and important as in now economy age statistics information affects the policy-making by the manager of enterprise. At present, there exists some problems in statistics analysis that it's hard to touch and reveal the true facts to analyse, so we can only judge the case as it stands. Therefore, to change the matter, statistics members have to collect a vast amount of data, master basic statistics theory?methods and certain academic knowledge proficiently, clear som...

新经济时代统计信息影响企业管理层决策成败，统计分析的任务更趋繁重，作用更显重要；现阶段统计分析存在着一些问题，统计难以接触、揭示真实情况，统计分析也只能是就数论数；要改变这种情况，统计人员必须大量收集资料，熟练掌握统计基本理论、方法及一定的专业知识，明了党和国家有关方针政策，有效发挥统计分析作用，开展专题分析，不断创新，开辟新视角、新思路，采用科学方法，运用现代技术，做好统计分析，提高统计质量。

Primarily, the thesis assays the condition of network framework, the network was divided into three levels in terms of network management in order to establish the distributed method ,and still pointing out the intention and denotation of studying the Topology Discovery.Next, the thesis analyzes SNMP protocol minutely, including its development, principle, and the Network Management system that established on the SNMP protocol. Have analysed MIB in detail and the application way of MIB in network management .The thesis also assays the ICMP protocol, describing its working principle and the format of datagram minutely , and describing two important tools of ICMP- Ping and TraceRoute in detail. On the base of upper analysis, the thesis expounds a kind of distributed Topology Discovery project, and book it in one autonomy system. Topology Discovery was divided into two levels in terms of network management, and analyses the way of linking up between the two level. The thesis minutely assays Router-Level Topology Discovery technology basing on SNMP and Subnet-Level Topology Discovery technology basing on ARP and ICMP. According to these analyses, the thesis explores the specific methodology and the technology of XML data object which using the WinSNMP API to achieve topology discovering system on the development platform of Visual C++, and also analyses the technology of topology analysis and topology graph minutely. Moreover, the thesis assays the technology of basic firewall and Topology Discovery response strategy. Finally, the thesis analyses the underlying blind problem of the topology finding, and also analyses the reason that the blind problem produced and the way that reduced. The distributed algorithm that this paper puts forward has a certain directive significance in wireless network or other fields.

本文首先分析了网络结构状况，将网络从网络管理的角度划分为三个层次，为分布式的方法奠定了基础，同时还指出拓扑发现研究的目的及意义；接着本文分析了SNMP协议，详细分析了SNMP协议的发展状况，协议的工作原理，以及由SNMP协议基础上建立的SNMP网络管理体系，详细分析了MIB，以及MIB在网络管理上的应用方式；本文又分析了ICMP协议，详细描述了ICMP的工作原理和数据报格式，并详细描述了ICMP的两个重要工具-Ping 和TraceRoute；然后本文在结合上述分析的基础上，提出了一种分布式的拓扑发现方案，将拓扑发现拟订在一个自治系统内，将拓扑发现从网络管理角度划分为路由器级和子网级两个层次，分析了两个层次之间的衔接方式，同时从拓扑地域的角度将拓扑发现过程分布化，分析了分布式算法的具体方法和分布式结点之间的数据通讯方法，本文详细分析了基于SNMP的路由器级拓扑发现技术和基于ARP和ICMP的子网级拓扑发现技术；根据这些分析，本文利用XML数据对象作为分布式算法中的数据对象，分析了XML的技术，本文使用Visual C++开发平台实现网络拓扑发现系统，详细分析了使用WinSNMP API实现基于SNMP的路由器级拓扑发现和基于ARP的子网级拓扑发现，分析了使用Winsock编程实现基于ICMP的子网级拓扑发现，本文还对拓扑分析和拓扑图的绘制技术作了较细致的分析；本文最后还分析了基本防火墙技术，分析了几种类型的防火墙对拓扑发现带来的影响，以及在拓扑发现时的应对策略，本文还分析了拓扑发现中可能产生的盲点问题，分析了盲点产生的原因以及拓扑发现中减少盲点的方法。

This thesis Starts with theory analysis and practical analysis of the commercial circles, it has although explained the in herent related of commercial circles with advancing type relation of industry's theories, effect theory of the tiny drop, value chain theory, polarize the effect theory. It has introducted Riley's rule, Haffs probability rule and Hotaily's model, and regarded it as a tool to analyses the appeal of the trade circles. The thesis has analyzed the demand state, competition state, development potentiality, radiate strength of the trade circles, the place choosing of the trade circles, scale and function analysis, and advantage of the trade company in the trade circles.
