The above and other aspects, features and advantages of the present disclosure will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.
Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure that may be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
In a first aspect, to facilitate understanding of the present disclosure, a method for recovering an ip address provided by the present disclosure is first described in detail. As shown in fig. 1, for the recovery method provided by the embodiment of the present disclosure, according to the method steps shown in fig. 1, the problem that in the prior art, when a network is temporarily disconnected or a user terminal is not started and connected to the network, an IP address is recovered by mistake, so that accuracy of a detection result is low, and after the IP address is recovered by mistake, an original user terminal corresponding to the recovered IP address cannot access the network, so that resource waste is caused can be solved. The method comprises the specific steps of S101-S104.
S101, acquiring and responding to a recovery instruction, and sending a plurality of detection messages to each Internet protocol address according to time intervals.
In a specific implementation, a recovery instruction is obtained in real time and/or periodically, and after the recovery instruction is obtained, the recovery instruction is responded, that is, the detection of the internet protocol address is started. Optionally, after the recovery instruction is obtained, multiple probe messages are sent to each internet protocol address at time intervals. That is to say, a plurality of detection messages are sent for each internet protocol address, and a certain time interval exists between the sending times of two adjacent detection messages, so that the problem that when only one detection message is sent, the response message of the user terminal cannot be received due to the fact that the current network is temporarily disconnected or the user terminal is not started and connected with the current network is avoided, and the problem that the internet protocol address is recovered by mistake subsequently is avoided.
It should be noted that, in the case where the recycle instruction is not acquired, the probing of the ip address is not performed.
Optionally, the embodiment of the present disclosure provides the following two ways to generate the recycle instruction, where the first way is: and determining whether a preset period is reached, and generating a recovery instruction under the condition that the preset period is reached, namely setting a preset period aiming at the current network, wherein the preset period is used for indicating and detecting the Internet protocol address in the current network. The preset period may be set to be one week, three days, one month, or the like, and as an example, the preset period is set based on the attribute of the current network, the number of the accessed user terminals, or the like, for example, in a scenario where the current network is an internal network of a company and the number of the accessed user terminals is relatively fixed, the preset period may be set to be longer, such as one month; in a scene that the current network is a public network and the change frequency of the accessed user terminal is high, the preset period can be set to be short, such as three days.
The second way of generating the recycle instruction provided by the embodiment of the present disclosure is: it is determined whether an address assignment request is received, wherein the address assignment request is sent by a new user terminal that does not access the current network, that is, a new user terminal requests to access the current network. Further, in a case where an address allocation request is received, a recycle instruction is generated, as an example, in a case where an address allocation request is received, it may be further determined whether an unallocated internet protocol address in a current network meets a second condition, where the second condition is that a ratio of the unallocated internet protocol address to all internet protocol addresses is smaller than a preset ratio, the preset ratio is a ratio of an internet protocol address which is unallocated to a new user terminal in the current network to all internet protocol addresses, the preset ratio is also determined based on an attribute of the current network, for example, in a scenario where a bandwidth of the current network is large, the preset ratio may be set to be smaller; in the current scene of small network bandwidth, a preset proportion can be set to be large, and the like. And then, after determining that the unallocated internet protocol address meets a second condition, that is, determining that the allocable internet protocol address in the current network is insufficient, at this time, generating a recycling instruction.
Of course, in the same network, the recovery instruction may be generated only by the first manner or the second manner, or the recovery instruction may be generated by the first manner and the second manner, which is not specifically limited in this embodiment of the present disclosure.
S102, determining whether a response message returned by the user terminal corresponding to each Internet protocol address meets a first condition or not, wherein the response message is obtained by the user terminal responding to the detection message, and the first condition is that the ratio of the first quantity of the response message to the second quantity of the detection message is smaller than a preset threshold value.
After a plurality of detection messages are sent to each internet protocol address according to time intervals, a response message returned by a user terminal corresponding to the internet protocol address is received in real time aiming at each internet protocol address.
After receiving a response message returned by the user terminal corresponding to the internet protocol address, determining whether the response message returned by the user terminal corresponding to the internet protocol address meets a first condition, where the response message is obtained by the user terminal responding to the detection message, and the first condition is that a ratio of a first number of the response messages to a second number of the detection messages is smaller than a preset threshold, for example, 5 detection messages sent to the internet protocol address are set, and the preset threshold is 0.6, and if the number of the received response messages is 4, a ratio of the first number to the second number is 4/5 ═ 0.8, which is larger than the preset threshold 0.6, and further determining that the response message returned by the user terminal corresponding to the internet protocol address does not meet the first condition; if the number of the received response messages is 2, the ratio of the first number to the second number is 2/5-0.4, which is smaller than the preset threshold value 0.6, and it is further determined that the response message returned by the user terminal corresponding to the internet protocol address satisfies the first condition.
S103, under the condition that a response message returned by the user terminal corresponding to the Internet protocol address meets a first condition, updating the current identifier of the Internet protocol address, wherein the current identifier represents the times that the response message returned by the user terminal corresponding to the Internet protocol address continuously meets the first condition.
And under the condition that a response message returned by the user terminal corresponding to the Internet protocol address meets a first condition, indicating that the user terminal corresponding to the Internet protocol address does not use the Internet protocol address, and updating the current identifier of the Internet protocol address at the moment. The current identification represents the times that a response message returned by the user terminal corresponding to the Internet protocol address continuously meets the first condition.
As an example, the current identifier is a numerical value, and at this time, when the current identifier of the internet protocol address is updated to obtain an updated identifier, the current identifier may be directly subjected to the processing of adding 1 to obtain the updated identifier, and then the current identifier is updated by using the updated identifier, that is, the current identifier is modified into the updated identifier.
And S104, determining whether to recycle the corresponding Internet protocol address based on the updated identifier.
After the updated identifier is obtained, determining whether to recycle the corresponding internet protocol address according to the updated identifier, as one example, a preset number of internet protocol addresses can be recycled according to a descending order of the number of times that a response message returned by the user terminal corresponding to the internet protocol address continuously meets the first condition; optionally, the number of requests of the received address allocation requests may be determined first, and then the internet protocol addresses of the number of requests are recovered according to a descending order of the number of times that response messages returned by the user terminals corresponding to the internet protocol addresses continuously satisfy the first condition, so as to achieve the purpose that the new user terminals access the current network.
In specific implementation, under the condition that a response message returned by a user terminal corresponding to an internet protocol address does not satisfy a first condition, that is, a ratio of a first number of the response messages to a second number of the detection messages is greater than or equal to a preset threshold, that is, the user terminal corresponding to the internet protocol address uses the internet protocol address, at this time, it is determined whether a current identifier of the internet protocol address is a preset identifier. If the current identification of the internet protocol address is determined not to be the preset identification, changing the current identification of the internet protocol address to be the preset identification, wherein the preset identification represents that the internet protocol address is allocated, for example, setting the preset identification to 0.
And after the updated identifier is obtained, receiving an address allocation request in real time, responding to the address allocation request, namely reallocating the recovered internet protocol address so as to meet the request of a new user terminal for accessing the current network.
After the recovery instruction is obtained, the recovery instruction is responded, a plurality of detection messages are sent to each internet protocol address according to time intervals, so that one detection on each internet protocol address is completed, whether a response message returned by a user terminal corresponding to each internet protocol address meets a first condition is further determined, if yes, a current identification of the internet protocol address is updated to obtain an updated identification, whether the corresponding internet protocol address is recovered is determined based on the updated identification, the problem of mistaken recovery of the internet protocol address caused by temporary network disconnection of a network or non-starting and non-connection of the user terminal is avoided, and the accuracy of recovery of a detection result is improved; and moreover, the original user terminal corresponding to the Internet protocol address can normally use the network, and resource waste is avoided.
