Abstract
The invention provides a Web technology based network topological generation method. The method can help managing staff to know network connection conditions, effectively reflect network faults to the managing staff, and overcome defects that traditional network topological graphs generated by webmaster software are poor in effect, need to be adjusted by much labor and can not meet requirements for cross-platform and mobility of modern network management due to the fact that the traditional network topological graphs rely on operation systems or even a hardware platform and are limited geographically to management work stations.
Description
Technical field
The present invention relates to networking technology area, specifically a kind of Generating Network Topology Map based on the Web technology.
Background technology
Along with the development of network, scale increases, and complexity increases, and simple network management technology can not adapt to the requirement that network develops rapidly.Network management system in the past is the dedicated system developed in the network system of oneself of manufacturer often, very difficult network system to other manufacturers, communication equipment software etc. manage, this situation interconnected development trend of network isomery that is far from suitable, network develops rapidly, causes network configuration more complicated; Making rapid progress of network application allows the network manager all will face new problem every day.A lot of enterprises and institutions do not know how to go to solve running into network problem, see flow, pull out the means such as netting twine, and the investigation cycle is long, also very difficult real find problem.
Network service is being occupied consequence in the information technology of current high speed development, normal operation and assurance network service quality for maintaining network, need to provide the network management system with power to support at present, more and more important effect is being brought into play in network management in communication.
Along with being on the increase of the applications of computer network, the improving constantly of network complexity, network management system has become the inevitable choice of increasing enterprise.Good network management system, the whole topology of networks that need to manage of GPRS at first, this is effectively the network equipment to be carried out the basis of hardware configuration, performance monitoring, failure diagnosis etc.Therefore, network topological diagram becomes the important component part of network management system.Realization to network topological diagram in existing network management system is all undesirable, Presence of an interface dullness, complicated operation, underaction, is difficult to a lot of problems such as other functional modules in the integrated network management system.From the realization of drawing function, need especially to spend plenty of time and development of manpower Graphics Control, and function is very limited for the user.This method cost is high, and immature and poor expandability can't satisfy the increasing demand of user.
Generating Network Topology Map based on the Web technology, the method is accomplished in the intelligent network failure diagnosis that test is completed, the method can be under the Web environment automatic generating network topological diagram, effectively reduce network management personnel's intervention, display effect is preferably arranged, and the Web-Based Management system is can be trans-regional cross-platform carries out network management.
Summary of the invention
The purpose of this invention is to provide a kind of Generating Network Topology Map based on the Web technology.
The objective of the invention is to realize in the following manner, system configuration comprises: discovering network topological structure, the method (1) of extraction network equipment routing table; Extract the method (2) that network appliance address is transmitted, wherein:
Extract the method (1) of network equipment routing table, routing table is the foundation of network equipment forwarding data bag, every network equipment is made the operation that is forwarded to next gateway, abandons or is sent to local network to packet according to routing table, be used for obtaining the topological diagram of backbone network, the logical topological structure of discovering network; The step of extracting network equipment routing table is as follows: the logic topology information that goes out network according to the network address in routing table, next gateway address, subnet mask information analysis, or according to an initial router, obtain the routing table in router, then obtain the information of next routing table according to next gateway address of the record in routing table, obtain again the routing table in this router, the like, router to the last.
The method (2) that the extraction network appliance address is transmitted is used for obtaining the annexation of each equipment room of subnet, the physical topological structure of discovering network, step is as follows: in switch, will know the physical address of the network equipment that connects under the port for forwarding data between each port, port, these addresses have consisted of addresses forwarding table, according to the tree structure that automatically generates in switching domain, from Root Bridge, take the method that travels through, find out the topological connection relation between switch.
In switch, for forwarding data between each port, port need to be known the physical address of the network equipment that connects under the port, these addresses have consisted of addresses forwarding table, the addresses forwarding table of switch is a dynamic form, and this form is automatically to generate in the switch running.
The invention has the beneficial effects as follows: can be under the web environment automatic generating network topological diagram, effectively reduce network management personnel's intervention, display effect is preferably arranged, can realize the network management in cross-platform cross zone.

Fig. 2 is that network appliance address is transmitted the extraction flow chart.
Embodiment
With reference to Figure of description, method of the present invention is described in detail below.
The below describes with an instantiation process that realizes this method to content of the present invention.
As described in summary of the invention, architecture of the present invention mainly comprises:
Extract the method (1) of network equipment routing table, extract the method (2) that network appliance address is transmitted.
Wherein, the method (1) of extracting network equipment routing table is the core of whole architectural framework, can realize according to before narration; The method (2) that the extraction network appliance address is transmitted here introduces.
The implementation of extracting the method for network equipment routing table is described below: the exchange message that the switch set in each switching domain and annexation have been aggregated into whole management domain, the evaluating objects of algorithm is single switching domain.Basic thought is the spanning tree structure that automatically produces according in switching domain, from Root Bridge, adopts the level ergodic algorithm of tree, finds out the annexation between switch, and the algorithm that produces the switch set comprised for two steps:
(1) all switch objects of initialization generate switch S set witch Set.To transmit each address of acquisition from each port address of router, attempt obtaining mib variable sysServices and ipForwarding, as sysServices 〉=3﹠amp; ﹠amp; Can judge during ipForwarding=1 that this equipment is a switch, adds Switch Set. with it
(2) be classified as a class for the identical switch of mib variable dotldStpDesignatedRoot value in Switch Set, they are in same switching domain as can be known by Spanning-Tree Protocol.
Can obtain network routing table (router be connected with router annexation), generate tree table (switch be connected with switch annexation), R-S table (router be connected with switch annexation), subnet table (host address and connection in subnet address, mask and subnet) according to said method, these data are all deposited in database.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
