Abstract: With the fast development of computer network, the network management is becoming more and more complex. In order to improve the intelligence and operability of network equipment and service management, the high efficient and accurate discovery of network topology has been important process of network management. A method to conduct network topology autodiscovery in network layer and data link layer by using SNMP agreement was put forward, which enables topology discovery computation to become simpler and have high efficiency. 
