Embodiment Construction

[0020] As described in the background technology, the link layer topology construction method in the prior art mainly obtains the connection relationship between switches through the MAC address forwarding table. Since the MAC address forwarding table will be updated in real time, when the data in the MAC address forwarding table is not When it is complete, the constructed switch topology will be inaccurate, and there is a problem of low topology construction accuracy.

[0021] In order to solve the above-mentioned problems existing in the prior art, the technical scheme adopted in the embodiment of the present invention analyzes the connection data information collected in SNMP, and finds the connection relationship expressions that each switch connects to other switches through its own physical port through the MAC address , and analyze and organize the constructed connection relation expressions to obtain the corresponding switch topology without relying on the integrity of ...

Abstract

The invention discloses a switch topology construction method and a switch topology construction device. The method comprises the following steps: acquiring corresponding connection data information from switch simple network management protocol service, wherein the connection data information is correlated with a connecting relationship between switches; analyzing the acquired data information, and constructing a connecting relationship expression for connection of each switch with the other switches through own physical ports on the basis of MAC (medium access control) addresses; performing processing and analysis on the established connecting relationship expression to obtain a corresponding switch topology structure. According to the scheme, the link layer topology construction accuracy can be improved.

Description

technical field [0001] The invention relates to the network field, in particular to a method and device for constructing a switch topology. Background technique [0002] Network topology is a key element in network monitoring and management, which can intuitively reflect all devices in the network and the connection relationship between devices, so network topology discovery (construction) is of great significance. [0003] The existing protocol used for network monitoring and management is mainly Simple Network Management Protocol (Simple Network Management Protocol, SNMP). SNMP is an Internet management protocol based on the TCP / IP protocol. It consists of a set of network management standards. Each network management standard includes an Application Layer Protocol (Application Layer Protocol), a database model (Database Schema) and a set of resource objects. The protocol can support network management systems, which can monitor any situation that causes management concer...
