Abstract
The present invention provides an intranet network topology structure automatic discovery realization method, and relates to the system operation field. The intranet network topology structure automatic discovery realization method solves the problem that the network maintenance of the topological graph by hands is more and more difficult. The method comprises: automatically discovering and distinguishing a network device and a host, and obtaining a network topology structure. The intranet network topology structure automatic discovery realization method is applied to the business system operation so as to greatly improve the network management efficiency.
Description
Technical field
The present invention relates to system O＆M field, more particularly, to a kind of realization side of inner-mesh network automatic discovery of topological structure
Method.
Background technology
With the rapid growth of network size, network structure also assumes situation complicated and changeable.Traditional dependence webmaster handss
Work safeguards that latticed form has become extremely difficult carrying out network management.What this change in order to solve network brought asks
Topic is it is necessary to take the automatization of network management, and the premise of network automatically management is exactly opening up of our networks to be fully understood
Flutter structure and its change.Network topology can help network manager clearly to recognize current network condition, and network produces
Change and rapid locating network fault point.The method obtaining the most original of network topology is exactly to rely on network manager according to reality
Network draws its topology by hand, but in network that is complicated now huge and being in expansion growth trend, hand drawing to go out this
One network of sample needs to take a lot of time or energy, and accuracy and real-time also cannot ensure.
Content of the invention
In order to solve above technical problem, the present invention proposes a kind of realization side of inner-mesh network automatic discovery of topological structure
Method, can greatly improve the efficiency of network management
Technical scheme is as follows：
A kind of implementation method of inner-mesh network automatic discovery of topological structure, needs the network equipments such as switch in Intranet, router
Open SNMP.
Need to ensure all of equipment in same subnet.
For determining the IP address range of subnet, need to obtain IP address and subnet mask on a first main frame in subnet,
Then calculate the IP address range of subnet.
After taking IP address range, the IP address in scope is sent one by one arp request, record response IP and
MAC Address.
The IP address having response is attempted one by one with SNMP and obtains sysDesr information, and sysDesr information is filtered,
Obtain the list of the network equipment.
Obtain main frame default gateway IP and MAC Address, as the root node of topological structure.
To the network equipment in subnet, obtain the subordinate equipment list of the network equipment.One by one net is obtained by snmp protocol
The mac address of memory under each port of network equipment, removes the mac address of default gateway, obtains the subordinate equipment of this network equipment
List.
Calculate, sort out network topology structure according to the information getting.
The present invention can effectively reduce work time can energy it is ensured that accuracy and real-time, greatly improve
The efficiency of network management.
Brief description
Fig. 1 is the network equipment and lower extension list of devices；
Fig. 2 is the topology diagram being calculated according to list of devices.
Specific embodiment
Below more detailed elaboration is carried out to present disclosure：
1st, obtain IP address and subnet mask on a main frame first in subnet, then calculate the IP address range of subnet.
2nd, the IP address in scope is sent one by one with arp request, records IP and the MAC Address of response.
3rd, the IP address having response is attempted one by one with SNMP and obtains sysDesr information, and sysDesr information was carried out
Filter, obtains the list of the network equipment.The purpose filtering is the main frame opening SNMP service to remove some.
4th, main frame default gateway IP and MAC Address are obtained, as the root node of topological structure.Can pass through to access outer net,
Or read CONFIG.SYS obtaining.
5th, to the network equipment all of in subnet, obtain the subordinate equipment list of the network equipment.Pass through snmp protocol one by one
Obtain the mac address of memory under each port of the network equipment, remove the mac address of default gateway, obtain under this network equipment
Level list of devices.
6th, calculate, sort out network topology structure according to the information getting.As shown in Figure 1, Figure 2, with default gateway
（192.168.3.1）For starting point, find the most network equipment of the sub- equipment of lower extension（192.168.3.196）, it is that default gateway is straight
Connect child node.Then same operation is continued to child node, finds the lower most network equipment of child node of hanging as its child node,
Until subordinate does not have the network equipment, connect main process equipment to the corresponding network equipment.
7th, to the not treatable network equipment in the 6th step, calculate again lower extension child node most, straight as root node
Connect child node, circulated with this.
8th, to the 6th step and the not treatable main process equipment of the 7th step, it is directly connected to root node, direct as root node
Child node.
Due to hang under upper network equipment standby comprise to hang under undernet equipment standby, often processed and hung under one
Need after equipment to record, it is to avoid repeat to process same under hang standby.
