Referring to fig. 1, an embodiment of the present application provides a schematic configuration diagram of a configuration management database system. The configuration management database system 100 includes a controller 102, a switch 104 connected to the controller 102, and a memory 106, and a plurality of first servers 108 connected to the switch 104, each of which provides a data service, where the connection of the devices may be through the Internet or an Intranet, which is not limited herein.
In this application, the controller 102 and the switch 104 may be understood as servers, or any computers.
It should be noted that, the configuration management database system 100 according to the present application may include a plurality of switches 104, and each switch 104 is connected to a different server, and any switch is described in the present application.
In one possible embodiment, the controller 102 is a software defined network (Software Defined Network, SDN) controller.
Wherein, the SDN controller is an application in the SDN and is responsible for flow control to ensure the intelligent network. SDN controllers are data link layer based network communication protocols such as: openFlow et al protocols allow a server to tell a switch where to send a packet. It can be understood that the SDN controller can centrally manage the data acquired by each switch of the CMDB system, thereby improving the centralized management efficiency of the data.
In this application, the memory 106 is configured to store a plurality of second network information corresponding to the switch 104, where each second network information corresponds to one second server; the switch 104 is configured to obtain network information of each of the plurality of first servers 108, so as to obtain a plurality of first network information; when the preset duration is reached, sending the plurality of first network information to the controller 102; the controller 102 is configured to match the plurality of first network information and the plurality of second network information; and if the matching of the target first network information in the plurality of first network information and each second network information in the plurality of second network information fails, or the matching of the target second network information in the plurality of second network information and each first network information in the plurality of first network information fails, controlling the memory 106 to update the plurality of second network information into the plurality of first network information.
Wherein the network information includes at least a media access control address (Media Access Control, MAC) address, an internet protocol address (Internet Protocol, IP) or a port number of the server, etc. for describing an access address of the server; the network information can also comprise identification information such as the name of a server, and has uniqueness; the network information may further include network status information such as access duration and network rate of the server, which may be used to obtain computing power of the server, so as to facilitate resource allocation, which is not limited herein.

The first network information is the network information of the first server, and the second network information is the network information of the second server.
The method for the switch 104 to obtain the network information of each server is not limited in this application, and in one possible embodiment, the switch and the plurality of servers each employ a link layer discovery protocol (Link Layer Discovery Protocol, LLDP).
Among them, LLDP is simply a proximity discovery protocol. It defines a standard method for ethernet network devices, such as switches, routers and wireless lan access points, to announce its presence to other nodes in the network and to save discovery information for each neighboring device. Details such as device configuration and device identification may be advertised using the protocol.
Specifically, LLDP defines a general bulletin information set, a protocol for transmitting bulletins, and a method for storing received bulletin information. Devices that advertise their own information may transmit multiple pieces of advertising information in a local area network packet in the form of a Type Length Value (TLV) field.
It can be understood that when both the switch and the server adopt the LLDP protocol, the switch can discover the server connected thereto in real time, thereby rapidly acquiring network information of the accessed server.
The present application does not limit the preset duration, it can be understood that when the preset duration arrives, the switch 104 sends a plurality of second network information to the controller 102, so that the controller 102 can combine a plurality of first network information stored in the memory to determine whether to update the network resource or the physical device, thereby performing information maintenance at regular time, and improving the instantaneity of information maintenance.
In a possible embodiment, the controller 102 is further configured to obtain a first response frequency of the switch 104; acquiring the number of second servers corresponding to the plurality of second network information; and acquiring the preset duration according to the first response frequency and the number.
Wherein the first response frequency refers to a frequency of the switch 104 responding to the task assigned by the controller 102; the number refers to a number value of the plurality of second servers stored in advance in the memory 106; in the present application, a preset time period corresponding to the first response frequency and the number may be stored in advance.
The method for acquiring the preset duration by the first response frequency and the number is not limited, the first duration corresponding to the first response frequency and the second duration corresponding to the number can be acquired, and then the minimum value, the maximum value or the weighted value between the first duration and the second duration is acquired to obtain the preset duration.
It can be appreciated that the controller 102 obtains the first response frequency of the switch 104 and the number of second servers corresponding to the plurality of second network information, and then obtains the preset duration according to the first response frequency and the number. In this way, the response frequency of the current switch 104 is considered, and the number of servers previously connected to the switch 104 is considered, so that accuracy of acquiring the preset duration is improved.
In a possible embodiment, the controller 102 is specifically configured to obtain the current time in terms of obtaining the preset duration according to the first response frequency and the number; determining a second response frequency based on the number and the current time; acquiring a ratio between the first response frequency and the second response frequency; and acquiring the preset duration according to the ratio.
In the application, the running conditions corresponding to the time periods can be counted in advance, so that response frequencies corresponding to different numbers of servers in the time periods can be generated. Thus, in this embodiment, the second response frequency may be determined based on the number and the current time.
It will be appreciated that the controller 102 obtains the current time, determines the second response frequency according to the current time and the number, obtains the ratio between the first response frequency and the second response frequency, and obtains the preset duration according to the ratio. Therefore, the preset duration is acquired based on the second response frequency corresponding to the preset condition and the first response frequency corresponding to the current condition, and the accuracy of acquiring the preset duration can be further improved.
In this application, the matching between the target first network information and each of the plurality of second network information fails, and if the target first network information exists, the controller 102 may determine that the first server corresponding to the target first network information is a server newly accessed to or having an address changed from the switch. The matching of the target second network information and each of the plurality of first network information fails, and if the target second network information exists, the controller 102 may determine that the second server corresponding to the target second network information is disconnected from the switch or the address of the server is replaced.
In one possible embodiment, in the aspect of matching the plurality of first network information and the plurality of second network information, the controller 120 is specifically configured to obtain, from the plurality of first network information, an identifier and an access address corresponding to each of the plurality of first servers, so as to obtain a plurality of first identifiers and a plurality of first access addresses; acquiring an identifier and an access address corresponding to each second server in the plurality of second servers from the plurality of second network information to obtain a plurality of second identifiers and a plurality of second access addresses; matching the plurality of first identifications and the plurality of second identifications; if the target first identifier in the plurality of first identifiers is successfully matched with the target second identifier in the plurality of second identifiers, matching a first access address corresponding to the target first identifier with a second access address corresponding to the target second identifier; if the matching of the first access address corresponding to the target first identifier and the second access address corresponding to the target second identifier fails, determining that the first network information corresponding to the target first identifier is the target first network information, and determining that the second network information corresponding to the target second identifier is the target second network information; if the matching of the target first identifier and each of the plurality of second identifiers fails, determining that the first network information corresponding to the target first identifier is the target first network information; and if the matching of the target second identifier and each first identifier in the plurality of first identifiers fails, determining that the second network information corresponding to the target second identifier is the target second network information.

The network information also comprises an access address of the server, and the first access address is an access address corresponding to the first server, and the second access address is an access address corresponding to the second server.
It can be appreciated that the controller 102 obtains the corresponding identification information and the access address from the network information corresponding to the server, so as to obtain a plurality of first identifications, a plurality of first access addresses, a plurality of second identifications and a plurality of second access addresses. And matching the plurality of first identifiers with the plurality of second identifiers, if the matching of the target first identifier in the plurality of first identifiers and the target second identifier in the plurality of second identifiers is successful, the server corresponding to the target first identifier and the target second identifier is still connected with the switch, further, identifying whether the first access address corresponding to the target first identifier and the second access address corresponding to the target second identifier are matched, if the matching is successful, the access address between the server and the switch is unchanged, and if the matching is failed, the access address between the server and the switch is changed. On the other hand, if the matching of the target first identifier and each of the plurality of second identifiers fails, the server is a server of the new access switch; if the target second identifier fails to be matched with each first identifier in the plurality of first identifiers, the server is disconnected with the switch, so that whether the server corresponding to the switch changes or not is judged according to the identifier information and the access address of the server, and the judgment accuracy is improved.
In this application, the memory may directly replace the plurality of second network information with the plurality of first network information, or may simply add the target first network information or delete the target second network information, so that the plurality of second network information is updated to the plurality of first network information, which is not limited herein.
It can be understood that, in the present application, the second network information of each second server corresponding to the switch is stored in advance through the memory to obtain a plurality of second network information, and then the switch obtains the network information of each first server connected to the second server to obtain a plurality of first network information, and when the preset duration arrives, the plurality of second network information is sent to the controller. And then, the controller matches the plurality of first network information with the plurality of second network information, if the matching of the target first network information in the plurality of first network information with each second network information in the plurality of second network information fails, or if the matching of the target second network information in the plurality of second network information with each first network information in the plurality of first network information fails, the server connected with the switch is changed, so that the controller controls the memory to update the plurality of second network information into the plurality of first network information. Thus, the access information of the server is updated, and the instantaneity of information maintenance is improved.
In a possible embodiment, referring to fig. 2, the configuration management database system shown in fig. 2 further includes a proxy server 105 connected to the switch 104, for acquiring the plurality of second network information and the plurality of first network information; matching the plurality of first network information and the plurality of second network information; if the target first network information exists, the target first network information is sent to the controller 102; if the target second network information exists, the target second network information is sent to the controller 102.
Wherein the proxy server 105 is configured to determine whether a server to be updated exists. The matching method may refer to the matching method of the controller 102, and will not be described herein.
