We present a SNMP-based topology discovery algorithm using direct connection theorem and simple connection theorem for judging relationship of switches in subnets. In order to in discover the map of network without SNMP, several key problems such as subnet guessing and multi-address routers are discussed in details. And then a topology discovery algorithm based on primitive protocols is presented. We also deeply study some routing protocols such as OSPF and BGP and propose a routing-protocols-based algorithm for topology discovery.

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.

Nevertheless, one might indicate a series of major steps as follows: the discovery of the early forms of the Oedipus complex and those of the ego and the superego, and the importance of the splitting, projective, and introjective mechanisms for building up the child's internal world; the discovery of the crucial place in development of the depressive position, linked with the infant's awareness of his mother as a whole and separate person; the discovery of the anxieties and mechanisms operating before the depressive position in the paranoid-schizoid position, the point of fixation of the schizophrenic group of illnesses; and finally the discovery of early oral envy and its influence on the early stages of development.

According to the writer, Li balances literary critics w...ith other artistic categories, and appreciates critical works from the height of aesthetics. From Li's brand-new perspective, critique is not only"independent"but also"artistic", which is of remarkable significance as regards its implication in the revolutionary changes of literary criticism. The 2nd chapter"literary criticism is a form of discovery", literarily refers to Li Jianwu stressed that critic main body consciousness to text permeating, and his claims on critics'subjectivity and capabilities in aesthetic judgments. The writer concludes Li's ideas as the three following aspects:"critique is self-discovery","critique is the discovery of the writer's mind", and"critique is the discovery of humanity in literature", and gives full illustration one by one.
