Abstract

The application relates to a SDN-based network topological structure discovery method and device, a computer readable storage medium and computer equipment. The method comprises the following steps: acquiring a SDN topological structure template produced when creating virtual network equipment; determining the virtual network equipment recorded in the SDN topological structure template; acquiringa network address corresponding to the determined virtual network equipment; sending a first detection instruction according to the network address, wherein the first detection instruction is used forindicating a physical server corresponding to the network address to send a first detection packet to the determined virtual network equipment; and judging that the virtual network equipment on the physical server is existent in the network topological structure when receiving a first reply packet for the first detection packet fed back by the physical server in the preset time slot. Through thescheme provided by the application, the network topological structure discovery efficiency can be improved.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular to an SDN-based network topology discovery method, device and storage medium. Background technique [0002] With the development of computer technology, SDN (Software Defined Network, software-defined network) technology appears. SDN is a new network innovation architecture and a way of realizing network virtualization. With the rapid development of software-defined networks, effective network management has received more and more attention, and obtaining the latest network topology is crucial for network management. [0003] The traditional network topology discovery usually adopts the method of blind test, that is, through various underlying protocols such as ICMP (Internet Control Message Protocol, Network Control Message Protocol), SNMP (Simple Network Management Protocol, Simple Network Management Protocol), LLDP ( Link Layer Discovery Protocol (Link Layer Dis...
