Research on computer network topology discovery technology

Network topology discovery is a technology that research for network structure by collecting network transmission data, which is important in network management and network security evaluation. Aimed at the key problem of network topology discovery, the research content and object in network topology discovery are generalized, the present external and internal research fruit are analyzed, several network topology discovery technologies based on protocol visual angle are generalized, the mechanism is expatiated and the use range and shortage of each discovery technology are pointed out, the development trend of network topology discovery technology is dicussed at last.
