Problems solved by technology
[0008] Therefore, the problems existing in the prior art are: 1. During the discovery process of the three-layer network, the discovery of the three-layer equipment depends on the routing table of the equipment. If the routing table of the equipment is incomplete, some three-layer equipment may be missed.
2. In Layer 2 network discovery, if there are many network segments in the Layer 2 network and the range of network segments is large, it is more reliable to use the Ping tool to detect each IP one by one, but it is time-consuming, and the FDB table of the device ages quickly, so Difficulties in forming a second-tier relationship

Embodiment Construction
[0033]Embodiments of the present invention will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
[0034] Figure 4 It is a flowchart illustrating a method for backbone network discovery according to an embodiment of the present invention.
[0035] Such as Figure 4 As shown, in step S401, the IP of the starting layer 3 device for layer 3 device discovery is determined. For example, the IP address of the gateway will be configured on the server where the NMS is located. This IP address is the IP address of a Layer 3 device. Here, the device corresponding to this IP address is used as the starting point for backbone network discovery.
[0036] Among them, the process of determining the initial value in the three-layer IP list (that is, determining whether the devic...

The invention provides a method for automatically discovering a hierarchical network topology. The method comprises the following steps of: determining three-layer equipment in an IP list according to value of a management information base (MIB) node ipForwarding (the forwarding label is a standard MIB node in the RFC-1213-MIB) acquired from the equipment MIB by using a simple network management protocol (SNMP); acquiring the routing list information of the determined three-layer equipment according to the MIB through the SNMP; obtaining a straight networking section and the next hop routing address through the acquired routing list information; detecting the connectivity of the equipment through a ping tool; and judging layer-2 switch equipment and acquiring a layer-2 equipment FDB table (MAC address forwarding table) through the SNMP according to Bridge-MIB, and acquiring detailed information of the equipment according to private MIB of the equipment.
Description
technical field [0001] The invention relates to automatic discovery of layered network topology, more specifically, a method for automatic discovery of layered network topology and a method for building layered network topology. Background technique [0002] Network topology is an important basis for NMS (Network Management Station) to manage and monitor the network. It can intuitively reflect the existing network environment to users in a graphical manner. Therefore, how to effectively discover network topology is very important in NMS. [0003] SNMP (Simple Network Management Protocol) is a common protocol used by the current NMS to manage and monitor network devices. The goal of SNMP is to manage the software and hardware platforms produced by many manufacturers on the Internet, so SNMP is also greatly influenced by the Internet standard network management framework. Through the SNMP protocol, according to the standard MIB (Management Information Base) in RFC and private...
