Problems solved by technology

Although the network topology discovery method based on the routing protocol can also discover the link connection relationship, the routing entries on most devices exist in the form of network segments, which cannot ensure that the topology is completely detected. The accuracy is low and the accuracy is high. As far as the computer room topology data is concerned, the effect is poor

Abstract

The invention discloses a method and device for determining a network topological structure, and relates to the technical field of computers. A specific embodiment of the method comprises the steps: obtaining first data related to a link layer discovery protocol so as to determine a connection relationship between network devices; obtaining second data related to an address resolution protocol and third data related to a medium access control protocol to determine a connection relationship between the network devices and the host; and determining a network topological structure based on the connection relationship between the network devices and the connection relationship between the network devices and the host. According to the embodiment, the network topology structure can be detected in real time; the precision is high; maintenance is easy; no extra network detection message is generated; and forwarding of a machine room device to the message is not affected.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for determining network topology. Background technique [0002] With the rapid development of Internet technology, the number of network devices in data centers of Internet and cloud computing companies is increasing, and the network topology is becoming more and more complex. Network topology discovery, as the most basic part of network monitoring and network troubleshooting, can speed up Network troubleshooting speed, providing operation and maintenance personnel with connections between networks. Among them, the network topology refers to the layout of various devices interconnected by transmission media, that is, the specific physical (real) or logical (virtual) arrangement among the members of the network. [0003] Currently, commonly used methods for discovering network topology include: a method for discovering network topology based on the snmp prot...
