It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a network device discovery method according to an embodiment of the present application, where the method is applicable to a case of discovering a new network device, and the method may be executed by a network device discovery apparatus, which may be implemented by software and/or hardware and is specifically configured in a network server.
Referring to fig. 1, the network device discovery method applied to a network server specifically includes the following steps:
s110, sending an IP address list query instruction to at least two network management terminals, and receiving an IP address list of network equipment of a self management network segment fed back by the corresponding network management terminal; wherein, different network management terminals manage different network segments.
The network management terminal is a service terminal for managing network devices in different network segments, and each network segment corresponds to one network management terminal. The network management end monitors the network equipment in the management network segment, automatically generates a notification message of a corresponding type when the network equipment is connected to a network or has an error report, and sends the notification message to the network management end of the corresponding network segment, and after receiving the notification message of the network equipment, the network management end extracts an IP Address (Internet Protocol Address) in the notification message and generates an IP Address list.
The network server sends an IP address list query instruction to the network management terminals according to a preset period, the number of the network management terminals is at least 2, and specifically, the number of the network management terminals is determined by the number of network segments in a monitoring range of the network server. The preset period may be set according to actual needs, for example, the period may be 8 hours, 1 day, or 1 week, and the like, and may be set according to the number of network management terminals and the frequency increase of the network device, and the present application is not particularly limited thereto. After receiving the query instruction sent by the network service end, the network management end sends the IP address list of the network equipment of the self management network segment to the network service end, and the network service end receives the IP address list fed back by each corresponding network management end.
A network may be divided into multiple segments, and network devices in different network segments have regional isolation, so it is difficult to timely and effectively discover network devices in multiple isolated regions. Because different network management ends manage different network segments, the network service end can overcome the defect that the network devices in different network segments have regional isolation by receiving the IP address lists of the network devices of the self-management network segments fed back by the different network management ends.
And S120, comparing the IP address list corresponding to each network management end with the IP addresses of the locally stored network equipment to obtain the IP addresses of the newly added network equipment.
The locally stored network device IP address is a network device IP address stored in the network server, that is, the network server has found and stored the network device IP address before receiving the IP address list of the network device fed back by each network management terminal.
The network server compares the IP address list corresponding to each network management terminal with the locally stored network equipment IP, and when the IP address which does not exist in the locally stored network equipment IP addresses is obtained through comparison, the IP address is the logic address of the network equipment in the network, and when a newly added IP address appears in the network, the fact that the newly added network equipment exists in the network is indicated, so that the IP address is the IP address of the newly added network equipment.
In an optional embodiment, comparing the IP address list corresponding to each network management end with the IP address of the network device locally stored in the network service end includes: carrying out duplicate removal on the IP addresses in each IP address list to obtain the IP address to be analyzed; and taking the IP address to be analyzed which does not exist in the IP addresses of the network equipment locally stored by the network server as the IP address of the newly added network equipment.
Multiple repeated IP addresses may appear in the IP address list, which may increase the workload of subsequent comparison with the IP address of the network device locally stored at the server, and reduce the discovery efficiency of the new device. Therefore, the network service end performs deduplication on the IP addresses in the IP address lists, that is, removes the repeated IP addresses in the IP address lists, and takes the IP addresses subjected to deduplication processing in the IP address lists as the IP addresses to be analyzed.
And comparing the IP address to be analyzed with the IP address of the network equipment locally stored by the network server. Specifically, if the comparison result is that the IP address to be analyzed exists in the IP addresses of the network devices locally stored by the network server, it indicates that the IP address to be analyzed is not the IP address of the newly added network device, and no processing is required; and if the comparison result shows that the IP address to be analyzed does not exist in the IP addresses of the network equipment stored locally at the network service end, the IP address to be analyzed is the IP address of the newly added network equipment, and the IP address to be analyzed is used as the IP address of the newly added network equipment and is stored locally at the network service end.
When the IP addresses to be analyzed which do not exist in the IP addresses of the network equipment which is locally stored by the network service end are found by comparison, the IP addresses to be analyzed which do not exist in the IP addresses of the network equipment which is locally stored by the network service end are indicated to be newly allocated in the network, namely, new network equipment is added in the network, the IP addresses to be analyzed which do not exist in the IP addresses of the network equipment which is locally stored by the network service end are the IP addresses of the newly added network equipment, and the newly added network equipment is monitored and timely found according to the uniqueness of the IP addresses.
According to the technical scheme of the embodiment, the IP address list query instruction of the internet protocol address is sent to at least two network management terminals, and the IP address lists of the network devices of the self management network segments fed back by the corresponding network management terminals are received, wherein the network segments managed by different network management terminals are different, so that the IP address lists of the network devices in different network segments can be obtained, and the isolation between different network segments is overcome. And comparing the IP address list corresponding to each network management end with the IP addresses of the network equipment stored locally, finding IP addresses which do not exist in the IP addresses of the network equipment stored locally at the network service end through comparison to obtain the IP addresses of the newly added network equipment, and finding the newly added network equipment through the IP addresses of the network equipment according to the corresponding relation between the IP addresses and the network equipment. The problem that in the prior art, due to the isolation among different network segments, a network server cannot effectively discover network equipment in different network segments is solved, and the effect of improving the effectiveness of network equipment discovery is achieved.
Example two
Fig. 2 is a flowchart of a flowchart method of a network device discovery method provided in the second embodiment of the present application, and the technical solution of the present embodiment is further refined based on the above technical solution.
Further, the network device discovery method further includes: acquiring associated information of the newly added network equipment, wherein the associated information comprises at least one of equipment name, serial number and equipment model; establishing a mapping relation between the associated information and the IP address corresponding to the newly added network equipment; and determining the network equipment clusters with the same IP address according to the mapping relation.
Referring to fig. 2, a network device discovery method includes:
s210, sending an internet protocol address IP address list query instruction to at least two network management terminals, and receiving an IP address list of network equipment of a self management network segment fed back by the corresponding network management terminal; wherein, different network management terminals manage different network segments.
S220, comparing the IP address list corresponding to each network management end with the IP addresses of the locally stored network equipment to obtain the IP addresses of the newly added network equipment.
S230, acquiring the associated information of the newly added network equipment, wherein the associated information comprises at least one of the equipment name, the serial number and the equipment model.
The association information is device identification information associated with the network device. For example, the association information may be at least one of a device name, a serial number, a device model number, and the like, wherein the serial number may uniquely identify the network device, and the serial number may be preferentially selected as the association information. And after the network server side obtains the IP address of the newly added network equipment, sending an associated information query instruction of the newly added network equipment to the network management side according to the IP address of the newly added network equipment to obtain the associated information of the newly added network equipment.
S240, establishing a mapping relation between the associated information and the IP address corresponding to the newly added network equipment.
And establishing a mapping relation with the corresponding IP address according to the acquired associated information, and storing the mapping relation in a local database. The mapping relation can record the name, serial number, equipment model and other information of the network equipment corresponding to the IP address, and the number of the network equipment is at least one.
And S250, determining the network equipment clusters with the same IP address according to the mapping relation.
The network device cluster is a cluster formed by a plurality of network devices. The same IP address can establish a mapping relation with at least one network device, when the same IP address establishes a mapping relation with a plurality of network devices, the plurality of network devices share one IP address, and a network device cluster with the same IP address is determined according to the mapping relation.
According to the technical scheme of the embodiment, the associated information of the newly added network equipment is obtained, the mapping relation between the associated information and the IP address corresponding to the newly added network equipment is established, the associated information can uniquely identify the equipment information of the network equipment, the network equipment cluster with the same IP address is determined through the mapping relation, and the network equipment information corresponding to the IP address of the newly added network equipment is perfected.
In an optional embodiment, the network device discovery method further includes: monitoring the associated information of each network device in the IP address of the locally stored network device, wherein the associated information comprises at least one of the device name, the serial number and the device model; if new associated information exists under the same IP address, establishing a mapping relation between the new associated information and the corresponding IP address; and determining newly-added network equipment in the network equipment cluster with the same IP address according to the mapping relation.
The network server monitors the associated information of each network device in the locally stored network device IP address according to a preset period, that is, the associated information of each network device in the locally stored network device IP address is obtained without finding the IP address of the newly added network device. It should be noted that the period for monitoring the associated information of each network device in the locally stored network device IP address may be the same as or different from the period for acquiring the IP address list, and this is not specifically limited in this application.
If new associated information exists under the same IP address, for example, a new serial number indicates that a network device is added under the IP address, a mapping relation is established between the new associated information and the corresponding IP address. The association information includes at least one of a device name, a serial number, and a device model number. And the network equipment corresponding to the new associated information and the original network equipment under the P address form a network equipment cluster of the IP address, and the newly added network equipment in the network equipment cluster with the same IP address is determined according to the mapping relation.
It should be noted that, if the original associated information in the IP address does not exist, that is, it is monitored that the original associated information does not exist in the IP address, it is indicated that the network device corresponding to the associated information has been removed from the network device cluster corresponding to the IP address, and at this time, the associated information is deleted, so that the storage resource of the network server can be saved, and meanwhile, the network device information can be updated in time. By deleting the nonexistent associated information and establishing the mapping relation between the new associated information and the corresponding IP address, the corresponding associated information can be automatically updated under the condition that the network equipment is replaced, and the accuracy of the mapping relation between the associated information stored by the network server and the corresponding IP address is guaranteed.
The method can effectively discover the newly added network equipment by monitoring the associated information of each network equipment in the locally stored network equipment IP address, can discover the new associated information existing under the IP address in time, and can discover the newly added network equipment under the same IP address.
