Problems solved by technology

[0003] The traditional topology discovery technology only discovers the logical network connections of the three layers, that is, discovers the connections between routers and subnets. This technology is obviously not suitable for the environment of switches.

Embodiment Construction

[0099] The prerequisites for the implementation of the program are

[0100] (1) Each switch is configured with an IP address, all of which are manageable, and all of them are implemented

[0101] BRIDGE-MIB defined by RFC1213-MIB and RFC1493;

[0102] (2) The host where the algorithm is running is installed with SNMP agent

[0103] (3) Both the active switch and the host respond to the PING message

[0104] The implementation system can be divided into four devices:

[0105] (1) Equipment determination device;

[0106] (2) Information collection device;

[0107] (3) information processing device;

[0108] (4) Topological information database;

[0109] (5) Topology display device;

[0110] Image 6 The interrelationships of the five devices are given. The device determining means includes determining the IP address range of the management domain, determining the set of active IP addresses, collecting device information and instantiating each physical device. The MIB i...

Abstract

The invention relates to a physical network topology finding system for computer network topology and general purpose MIB information and method thereof, which comprises, determining the IP address range of the administration domain, determining the active IP address aggregation in the network address range, determining subnet quantity, corresponding subnet number and subnet mask, mapping the IP address aggregation, obtaining the discovered address transferring table information belonging to the switchboard of the subnet, obtaining the connection between the ports of the switchboards. determining the connection between the host computer and the port of the switchboard. The system comprises: a determining device for the apparatus, an information gathering device, an information processing device, a topology display device. The invention is utilized to a variety of IP network( such as IPV4, IPV6, and IP telecommunication network).

Description

technical field [0001] The invention relates to computer network topology discovery and general MIB (management information base) library information, in particular to a physical network topology discovery system and method thereof, physical topology discovery based on such information and general topology discovery technology. Background technique [0002] Switches have become key devices in modern computer networks. For network administrators, it is extremely important to be able to obtain network topology information at any time. It can help determine link continuity, perform error correlation analysis, and place servers in the most appropriate locations. [0003] The traditional topology discovery technology only discovers the logical network connections of the three layers, that is, discovers the connections between routers and subnets. This technology is obviously not suitable for the environment of switches. Because the routing table of the router stores the informa...
