It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, 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 1
Fig. 1 is a flowchart of a network device discovery method according to an embodiment of the present application, where the embodiment is applicable to a case of discovering newly added network devices, and the method may be performed by a network device discovery apparatus, and the apparatus may be implemented by software and/or hardware and specifically configured in a network server.
Referring to the network device discovery method shown in fig. 1, the network device discovery method is applied to a network server, and specifically includes the following steps:
s110, sending an Internet protocol address (IP) address list query instruction to at least two network management ends, and receiving an IP address list of network equipment of a self-management network segment fed back by the corresponding network management end; wherein, the network segments managed by different network management terminals are different.
The network management end is a server end for managing network devices in different network segments, and each network segment corresponds to one network management end respectively. The network management end monitors the network equipment in the management network segment, when the network equipment is connected to the network or the error occurs, the network management end automatically generates a notification message of a corresponding type and sends the notification message to the network management end of the corresponding network segment, and after the network management end receives the notification message of the network equipment, the network management end extracts an IP address (Internet Protocol Address, an 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 end according to a preset period, the number of the network management ends is at least 2, and specifically, the number of the network management ends is determined by the number of network segments in the monitoring range of the network server. The preset period may be set according to actual needs, and exemplary periods may be 8 hours, 1 day, 1 week, etc., and may be set according to the number of network management ends and the increasing frequency of the network devices, etc., which is not specifically limited in the present application. After receiving the query instruction sent by the network server, the network management end sends the IP address list of the network equipment of the self management network segment to the network server, and the network server receives the corresponding IP address list fed back by each network management end.
A network may be divided into a plurality of segments, and network devices in different segments have regional isolation, so that it is difficult and time-efficient to discover network devices in a plurality of isolated regions. Because the network segments managed by different network management ends are different, the network service end can overcome the problem that the network devices in different network segments have regional isolation by receiving the IP address list of the network devices of the self-management network segment fed back by the different network management ends.
S120, comparing the IP address list corresponding to each network management end with the locally stored IP addresses of the network devices to obtain the IP addresses of the newly added network devices.
The locally stored network device IP address is a network device IP address stored in the network server, that is, the network server discovers and stores the network device IP address before receiving the IP address list of the network device fed back by each network management end.
The network server compares the IP address list corresponding to each network management end with the IP address of the locally stored network equipment, when the IP address which does not exist in the locally stored IP address of the network equipment is obtained through comparison, the IP address is the logic address of the network equipment in the network, and when the newly-increased IP address appears in the network, the newly-increased network equipment exists in the network, so that the IP address is the IP address of the newly-increased network equipment.
In an alternative embodiment, comparing the list of corresponding IP addresses of each network management end with the IP addresses of the network devices locally stored in the network service end includes: performing duplication removal on the IP addresses in each IP address list to obtain IP addresses to be analyzed; and taking the IP address to be analyzed which does not exist in the IP addresses of the network devices stored locally by the network server as the IP address of the newly added network device.
Multiple repeated IP addresses may appear in the IP address list, which increases the workload of subsequent comparison with the network device IP address stored locally at the server, and reduces the discovery efficiency of the new device. Therefore, the network server performs de-duplication on the IP addresses in each IP address list, that is, removes the repeated IP addresses in each IP address list, and uses the IP address after de-duplication processing of each IP address list as the IP address to be analyzed.
And comparing the IP address to be analyzed with the IP address of the network equipment locally stored in 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, the IP address to be analyzed is not the IP address of the newly added network device, and no processing is needed; if the comparison result shows that the IP address to be analyzed does not exist in the IP addresses of the network devices locally stored by the network server, the IP address to be analyzed is the IP address of the newly-added network device, the IP address to be analyzed is used as the IP address of the newly-added network device, and the IP address to be analyzed is locally stored at the network server.
By performing de-duplication on the IP addresses in each IP address list, the redundant workload of the subsequent comparison process can be reduced, the comparison efficiency is improved, when the comparison finds that the IP addresses to be analyzed are not present in the network device IP addresses stored locally by the network server, it is indicated that the IP addresses are newly allocated in the network, that is, new network devices are added in the network, the IP addresses to be analyzed are not present in the network device IP addresses stored locally by the network server, that is, the IP addresses of the newly added network devices are the IP addresses of the newly added network devices, and according to the uniqueness of the IP addresses, the monitoring of the newly added network devices is realized, and the newly added network devices are found timely.
According to the technical scheme of the embodiment, the IP address list query instruction is sent to at least two network management ends, and the IP address list of the network equipment of the self-management network segment fed back by the corresponding network management ends is received, wherein the network segments managed by different network management ends are different, so that the IP address list of the network equipment in different network segments can be obtained, and isolation among different network segments is overcome. Comparing the IP address list corresponding to each network management end with the IP addresses of the network devices stored locally, finding out the IP addresses which are not existed in the IP addresses of the network devices stored locally by the network service end through comparison, obtaining the IP addresses of the newly-added network devices, and finding out the newly-added network devices through the IP addresses of the network devices according to the corresponding relation between the IP addresses and the network devices. The method solves the problem that the network service end cannot effectively discover the network equipment in different network segments due to isolation among different network segments in the prior art, and achieves the effect of improving the discovery availability of the network equipment.
Example two
Fig. 2 is a flowchart of a flowchart method of a network device discovery method according to a second embodiment of the present application, where the technical solution of the present embodiment is further refined on the basis of the technical solution.
Further, the network device discovery method further includes: acquiring association information of newly-added network equipment, wherein the association information comprises at least one of equipment name, serial number and equipment model; establishing a mapping relation between the association 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 ends, and receiving an IP address list of network equipment of a self-management network segment fed back by the corresponding network management end; wherein, the network segments managed by different network management terminals are different.
S220, comparing the IP address list corresponding to each network management end with the locally stored IP addresses of the network devices to obtain the IP addresses of the newly added network devices.
S230, acquiring association information of the newly-added network equipment, wherein the association information comprises at least one of equipment name, serial number and 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, etc., where the serial number may uniquely identify the network device, and the serial number may be preferentially selected as the association information. After the network server obtains the IP address of the newly-added network device, the network server sends an associated information inquiry instruction of the newly-added network device to the network management end according to the IP address of the newly-added network device, and the associated information of the newly-added network device is obtained.
S240, establishing a mapping relation between the association 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 association information, and storing the mapping relation in a local database. The information such as the name, serial number and equipment model number of the network equipment corresponding to the IP address can be recorded through the mapping relation, and the number of the network equipment is at least one.
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 and a plurality of network devices establish the mapping relation, the plurality of network devices share one IP address at the moment, and a network device cluster with the same IP address is determined according to the mapping relation.
According to the technical scheme, the association information of the newly-added network equipment is obtained, the mapping relation between the association information and the IP address corresponding to the newly-added network equipment is established, the association information can uniquely identify the equipment information of the network equipment, the network equipment clusters with the same IP address are 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 alternative embodiment, the network device discovery method further includes: monitoring association information of each network device in the locally stored network device IP address, wherein the association information comprises at least one of a device name, a serial number and a device model; if new association information exists under the same IP address, establishing a mapping relation between the new association 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 association information of each network device in the locally stored network device IP address according to a preset period, that is, obtains the association information of each network device in the locally stored network device IP address without finding the newly added network device IP address. The period of monitoring the association information of each network device in the locally stored IP address of the network device may be the same as or different from the period of acquiring the IP address list, which is not particularly limited in the present application.
If new association information, such as a new serial number, exists under the same IP address, which indicates that the network device is newly added under the IP address, a mapping relationship is established between the new association 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 association 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 association information in the IP address does not exist, that is, it is monitored that the original association information does not exist under the IP address, it is indicated that the network device corresponding to the association information has been removed from the network device cluster corresponding to the IP address, and the association information is deleted at this time, so that storage resources of the network server can be saved, and timely update of the network device information can be realized. By deleting the non-existing association information and establishing the mapping relation between the new association information and the corresponding IP address, the corresponding association information can be automatically updated under the condition of network equipment replacement, and the accuracy of the mapping relation between the association information stored by the network server and the corresponding IP address is ensured.
By monitoring the association information of each network device in the locally stored network device IP address, new association information can be found out in time under the IP address, newly-added network devices under the same IP address can be found out effectively, meanwhile, when the network devices under the same IP address are replaced, the association information of the replaced new network devices can be found out in time, the association information of the network devices in the network device cluster of the same IP address is automatically updated, manual modification is not needed, labor cost is saved, and the discovery efficiency of the newly-added network devices is improved.

The UDP 162 port is used for communication between the network management end and the network equipment, so that the communication efficiency is improved.
The device information base is a MYSQL (a database name) database for storing a list of IP addresses of network devices installed in the managed network segment. The network manager is provided with SNMPTT (SNMP Trap Translator, an SNMP notification message handler written in Perl) for converting the received SNMP notification message into a network device IP address. The network device sends a notification message based on SNMP (simple network management protocol) comprising IP address information, and after the network management terminal obtains the notification message, the network management terminal extracts the IP address information in the notification message through SNMPTT and stores the IP address information in a MYSQL database to form an IP address list.
