Abstract
The invention provides a method for judging equipment uniqueness based on a data exchange function and an IP network discovery server for realizing the method. The method for judging the equipment uniqueness in IP network discovery comprises the following steps: when the IP address of newly found equipment is different from the IP addresses of all the found equipment, judging the newly found equipment is new equipment; when the IP address of the newly found equipment is the same as those of the found equipment, further judging whether the newly found equipment and the found equipment configured with the same IP address support a simple network management protocol and have different equipment properties; if yes, judging the newly found equipment is the new equipment; and if no, judging the newly found equipment is the found equipment.
Description
Technical field
The present invention relates to the network management technology field, relate in particular to the discovering network topology technology in the network management technology.
Background technology
IP network finds it is the basis that network management system IP network management and monitoring state of network change, and by NMP, finds and collect topological structure in the IP network, equipment composition information.Simple Network Management Protocol (SNMP) is a most popular device management protocol in the present IP network.Change owing to equipment in the IP network, new discovery equipment at first needs to search in the equipment that has been found that according to certain uniqueness characteristic, if can not find then think newfound equipment, this treatment step processing mistake can duplicate equipment and mistake is updated the equipment, existing technology is judged by the sequence number of fetch equipment mostly, if the sequence number of two equipment is same before and after finding, just be judged as same equipment.
One sequence number judgment device uniqueness by fetch equipment of prior art, rather than be used for the uniqueness of judgment device with the exchanges data that equipment plays in IP network.Owing to be not used for the uniqueness of judgment device with exchanges data, will cause equipment replacement after, though the Equipment Serial Number difference after changing, under the unaltered situation of the function of its Data transmission, the judgement of IP network discovering device is inaccurate.For example, a device hardware damages, and has used an other standby host to replace, the slave unit sequence number is judged, the sequence number difference of two machines, and they are different equipment, and equipment as an alternative, the exchanges data effect that it plays in network is identical.From the angle of network management, at discovering device and carry out the essence that uniqueness judges and be, whether the equipment of wishing to judge current discovery is equipment with new data exchanging function in the network, rather than only whether the physical entity that characterizes of its sequence number is new.With the replacement equipment is example, and it has the identical data exchange interaction equipment before replacing and the equipment after the replacement in network, and ideally, when the judgment device uniqueness, two equipment should be judged as same equipment, only are that new equipment has been replaced old equipment.In addition, the definition of the product ID of different vendor is different, each other can not be compatible, and use sequence number in the equipment of single manufacturer, to judge, can not in comprising the IP network of multiple vendor equipment, use.
Summary of the invention
Technical problem to be solved by this invention is that a kind of IP network discovery server that comes the method for judgment device uniqueness and realize this method based on data exchanging function is provided.
The present invention addresses the above problem the technical scheme that is adopted to be, the judgment method of equipment uniqueness during IP network is found comprises:

When there is identical situation the IP address of new discovery equipment with the IP address of discovering device, judge further then whether new discovery equipment has with the discovering device that disposes identical ip addresses and all support Simple Network Management Protocol and device attribute situation inequality, in this way, judge that new discovery equipment is new equipment; Otherwise, judge that new discovery equipment is discovering device.
Communication equipment is the exchanges data path of realizing in the different IP address of use on the different network interfaces between the different IP network in the IP network, finishes data communication between IP network, realizes the exchanges data of data from a network to the another one network.Under the immovable situation in IP address of IP network equipment interface quantity and correspondence, other parameters such as the title of change equipment, sequence number can not change the exchanges data effect of this equipment in IP network.Under one situation, just can learn with the IP address configuration of discovering device whether both data exchanging functions in network are identical by the IP address of new discovery equipment relatively.Do not support the equipment of SNMP, have and the identical situation in IP address of discovering device that then can judge new discovery equipment immediately and be discovering device, as difference, then can judge new discovery equipment immediately is new equipment as the IP address of new discovery equipment.But the equipment at supporting SNMP can comprise a plurality of network interface IP, just makes to judge the complexity that becomes.The analysis found that the IP address of the new discovery equipment of support SNMP is identical with the IP address of the discovering device of supporting SNMP, data exchanging function situation inequality also can occur, at this moment, the present invention introduces device attribute and does further judgement.Use the just uniqueness of specified data interactive function exactly of IP address and network interface title.Further, device attribute can comprise that also the exchanges data of IP address flows to.
Find server for the IP network that realizes said method, comprise device discovery module, facility information memory module, equipment uniqueness judge module;
The device discovery module is used for, discovering device in IP network, and the IP address and the device attribute of collecting new discovery equipment;
The facility information memory module is used for, and stores the IP address and the device attribute of discovering device;
The equipment uniqueness judge module is used for, the IP address of the discovering device of storing in the IP address of comparison new discovery equipment and the facility information memory module, all different when the IP address of new discovery equipment with the IP address of all discovering device, judge that then new discovery equipment is new equipment; When there is identical situation the IP address of new discovery equipment with the IP address of discovering device, judge further then whether new discovery equipment has with the discovering device that disposes identical ip addresses and all support Simple Network Management Protocol and device attribute situation inequality, in this way, judge that new discovery equipment is new equipment; Otherwise, judge that new discovery equipment is discovering device.
Further, the equipment uniqueness judge module also is used for, and is judging after new discovery equipment is new equipment, creates the IP address and the device attribute of described new discovery equipment in the facility information memory module; Judging new discovery equipment, the information of discovering device corresponding in the facility information memory module is upgraded for behind the discovering device.The renewal here is meant, though new discovery equipment and discovering device have identical IP address, not necessarily the IP number of addresses is just the same, and this part different information needs to upgrade, and what need in addition to upgrade is this data processing.
The invention has the beneficial effects as follows, the method of the data exchanging function judgment device uniqueness by equipment, make IP network find that the judgement that is applied in the network management is more accurate, effectively avoid equipment of duplicating and mistake to update the equipment, significantly promote the effectiveness that the network management system network is found; Simultaneously, solve to use sequence number to judge the problem that uniqueness can only compatible single vendor equipment, possessed the scope of application widely, be applicable to that the network of large-scale IP network network management system finds that different vendor's equipment in the IP network is possessed general applicability.
