Description
Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to an ip address resource management method, a cloud gateway, an electronic device, and a storage medium.
Background
In the management of the current network address resources, a sub local area network is mainly used, namely, the terminal equipment is accessed to the optical modem/router, the ip address applied by the terminal is provided by the router, and belongs to a private network address, the private network address currently has two types of dynamic ip addresses and static ip addresses, the dynamic ip addresses are temporary and can be changed when the system or the router is restarted, the static ip addresses are not changed and are autonomously configured by the terminal, and the system can be kept unchanged for weeks, months or even years. At present, the dynamic ip address is maintained by a lease mechanism, i.e. a fixed lease is configured at the dhcp server end, and after the terminal leases the ip successfully, the ip can be used in the lease. The static ip address is self-configured by the terminal, which can directly use the ip to access the network.
In the current ip address resource release scheme, the release time of the dynamic ip address depends on the lease configuration of the ip address, if the terminal is offline before the lease is over, the dynamic ip address resource still is occupied for a period of time, and other users who want to access the network can access the network due to insufficient resources and fail to access the network normally. The main release scheme of the static ip address is timing cleaning and flow statistics, but because the static ip address is autonomously configured by a user, the adoption of the timing cleaning can cause short-term network fluctuation and even network disconnection risks of the user, and the adoption of the flow statistics has larger error, because no flow generation at present can be that the user is off line or in a standby state, and if the static ip address resource is directly recovered, the normal use of the standby user can be influenced.
In summary, the current network resource management method has the technical problem of inaccurate ip address resource recovery time, and needs to be improved.

The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
Referring to fig. 2, fig. 2 is a flow chart of an ip address resource management method according to an embodiment of the present application, where the method specifically includes:
s1: and acquiring real-time flow data of the target terminal.
The ip address resource management method is applied to a cloud gateway, and the cloud gateway is equipment used as an intercommunication bridge between local and cloud services. The target terminal refers to any terminal accessing the network through the cloud gateway, and before the target terminal accesses the network, the target terminal needs to acquire its own ip address, where the ip address may be a static ip address or a dynamic ip address, and is specifically determined according to the requirement of the target terminal. If the static ip address is the static ip address, the cloud gateway allocates the static ip address to the target terminal, and configures a fixed lease period, after the target terminal leases the dynamic ip address successfully, the ip address can be used in the lease period, and if the static ip address is the static ip address, the target terminal configures the static ip address by itself. For convenience of explanation, the dynamic ip address is taken as an example in this embodiment.
As shown in fig. 3, the cloud gateway in the present application includes a network resource management module, a traffic statistics analysis module and a resource detection recovery module, where the target terminal sends a dhcp message to the cloud gateway to apply for a dynamic ip address, and the network resource management model of the cloud gateway allocates an unoccupied ip address to the target terminal from an address pool in response to a request of the message, so that the target terminal can normally use the ip address to access the network. The target terminal generates real-time flow data when accessing the network, and does not generate real-time flow data when stopping accessing the network, and the work of acquiring, counting, analyzing and the like of the real-time flow data is responsible for a flow statistic analysis module of the cloud gateway.
S2: and determining the latest time of the target terminal accessing the network according to the real-time flow data, and obtaining the time difference between the latest time and the current time.
As shown in fig. 3, the traffic statistics analysis module acquires and counts the real-time traffic data, if the real-time traffic data can be counted all the time, it indicates that the target terminal is accessing the network all the time, the traffic statistics analysis module only needs to keep the statistics state, and if the real-time traffic data is not counted in a fixed period, the traffic statistics analysis module needs to calculate the timeout time for the target terminal to stop accessing the network, and decides whether to notify the resource detection recovery module to perform the subsequent work according to the timeout time.
Specifically, the flow statistics analysis module counts real-time flow data, so that the latest time of the target terminal accessing the network, namely the last access time, can be obtained, and the time difference DeltaT between the latest time T1 and the current time T2, namely the overtime time, is calculated. If the target terminal is accessing the network all the time, the latest time T1 is changed all the time, the time difference DeltaT is 0, if the target terminal stops accessing the network at a certain moment, no real-time traffic data can be generated from the moment, the real-time traffic data can be generated again until the target terminal restarts to access the network, the latest time T1 is the moment of stopping accessing, and the value of the time difference DeltaT is gradually increased along with the current time T.
In one embodiment, S2 specifically includes: acquiring a flow monitoring period of a target terminal; based on the flow monitoring period, the time difference between the latest time and the current time is calculated regularly. When calculating the time difference, a timing calculation method may be adopted, and before calculating the time difference, a flow monitoring period of the target terminal needs to be set, for example, 10 seconds is taken as a period, the value is stored in advance, meanwhile, a timer is maintained in the cloud gateway, and after the value is obtained, calculation is performed once at a fixed time of each flow monitoring period based on the value.
In one embodiment, the step of obtaining the traffic monitoring period of the target terminal specifically includes: according to the historical flow data of the target terminal, determining a first access time period and a second access time period of the target terminal, wherein the offline rate of the target terminal in the first access time period is higher than a threshold value, and the offline rate of the target terminal in the second access time period is not higher than the threshold value; and respectively acquiring a first flow monitoring period of the target terminal in a first access time period and a second flow monitoring period of the target terminal in a second access time period, wherein the first flow monitoring period is smaller than the second flow monitoring period. The step of calculating the time difference between the latest time and the current time at fixed time based on the flow monitoring period specifically comprises the following steps: in the first access period, the time difference between the latest time and the current time is calculated based on the first flow monitoring period timing, and in the second access period, the time difference between the latest time and the current time is calculated based on the second flow monitoring period timing.
When the flow monitoring period of the target terminal is set, a fixed value such as 10 seconds can be set, the network access condition of the target terminal in the historical time period can be analyzed, and different periods are set for timing calculation according to the analysis result, so that whether the target terminal is offline or not can be rapidly known, and calculation resources can be saved. Specifically, the historical flow data of the target terminal in a historical time period is obtained, the historical time period can be a past week, a month or other time periods, and the historical time period can be specifically selected according to the needs. The historical flow data is analyzed to obtain the offline rates of the target terminal in the historical time periods in which time periods in the day are higher and which time periods are higher
The lower time period with higher offline rate is taken as a first access time period, the lower time period 5 with lower offline rate is taken as a second access time period, and then a first flow monitoring period is set for the first access time period, so that the method is that
The second access period sets a second traffic monitoring period. The duration of the first flow monitoring period is smaller than that of the second flow monitoring period, for example, the first flow monitoring period is 10 seconds, the second flow monitoring period is 20 seconds, and the like. In the subsequent calculation, if it is currently located in the first access period of the day
In, the timing calculation of the time difference is performed more frequently based on the first traffic monitoring period, which is relatively less based on the second traffic monitoring period if 0 is currently located in the second access period of the day
Timing calculations of the time differences are frequently performed.
Since the target terminal has a higher offline rate in the first access period in the past period, the probability of recovering the ip address resource in the period is also higher, so that the time can be calculated each time
The period of the difference is set shorter to ensure that the ip address resource can be quickly recovered 5 after the target terminal is taken off line. And since the target terminal has a lower offline rate for the second access period over the past period of time,
the probability that the ip address resource does not need to be recovered in the time period is also larger, so that the period of each calculation time difference can be set longer, and balance is realized before the ip address resource recovery opportunity is accurately calculated and the calculation resources are saved.
S3: and when the time difference is larger than the preset difference value, sending a reachability detection message to the target terminal.
0 when the time difference DeltaT calculated by the flow statistics analysis module is greater than a preset difference value T0, the method indicates that
The target terminal stops accessing the network for a long time and may be offline, and at this time, the resource detection and recovery module is triggered to send a reachability detection message to the target terminal to detect whether the target terminal is online.
In one embodiment, S3 specifically includes: if the target terminal is the IPV4 terminal, the target terminal is oriented
An end sends an arp unicast message; and if the target terminal is the IPV6 terminal, sending an ns unicast 5 message to the target terminal. As shown in fig. 3, the target terminal connected to the cloud gateway may be an IPV4 terminal or an IPV6 terminal, where IPV4 and IPV6 are different versions of the IP protocol, and the arp message and the ns message are messages of different protocols, but are all international general protocols, and for two types of target terminals, the most suitable messages of each type of terminal are respectively adopted to perform reachability detection. Reachability probe used in embodiments of the present application
The test messages all adopt the international standard protocol, so that the non-universality of the custom standard is avoided, the development time is saved, and the development efficiency is improved.
S4: and if the response message returned by the target terminal is not received under the preset condition, recovering the ip address resource of the target terminal.
As shown in fig. 3, if the target terminal returns a response message after receiving the reachability detection message, the resource detection and recovery module determines that the target terminal is in a standby state after receiving the response message, and in this state, although the network is not currently accessed, the ip address resource of the target terminal needs to be reserved, and then the ip address resource is not recovered. If a response message returned by the target terminal is not received under the preset condition, the resource detection and recovery module judges that the target terminal is off line currently, the ip address resource is directly released and recovered to the idle address pool, and when the network resource management module receives a new ip address application, the recovered ip address resource can be optionally reassigned to other terminals so as to improve the utilization rate of the ip address resource. The preset condition may be that the reachability detection message is successfully sent once and a certain period of time has elapsed, or that the reachability detection message is successfully sent many times and a certain period of time has elapsed, etc.
In one embodiment, S43 specifically includes: and when the time difference is larger than the preset difference value, sending a preset number of reachability detection messages to the target terminal at preset time intervals. S4 specifically comprises the following steps: if the response message returned by the target terminal is not received after the last reachability detection message is sent out, recovering the ip address resource of the target terminal after a preset time period.
When the reachability detection message is sent, if the reachability detection message is sent only once, the target terminal is not disconnected but does not receive the response message due to abnormal sending or abnormal receiving, so that misjudgment on the target terminal is caused. Therefore, the method and the device send the preset number of reachability detection messages to the target terminal at preset time intervals, for example, the reachability detection messages are sent 1 time every 0.5 seconds, the total number of the reachability detection messages is 3 times, after the 3 rd time of sending is finished and a preset time period (for example, 1 second is passed), the possibility of misjudgment is small, the target terminal can be judged to be offline, and the ip address resource of the target terminal can be recovered. The specific values of the preset time intervals, the preset number and the preset time period can be set and adjusted according to the actual scene, and in this way, the probability of misjudgment can be reduced, and the accuracy of judging the recovery time is improved.
In one embodiment, after S3, further comprising: judging whether the target terminal is in a long-term standby state according to the times of continuously receiving the response message; if yes, the current flow monitoring period is adjusted, and the time difference between the latest time and the current time is calculated based on the new flow monitoring period at regular time.
If the target terminal is in a standby state for a long time, the time difference is larger than the preset difference value each time when the time difference is calculated regularly, the resource detection recovery module is triggered each time to send the reachability detection message to the target terminal, and the response message is received after each time the reachability detection message is sent, but ip address resources cannot be recovered when the target terminal is in the standby state for a long time, and related resource waste is caused by frequent calculation, message sending and response message operation. Therefore, it is possible to determine whether the target terminal is in a long-term standby state according to the number of times the response message is continuously received, and then determine whether the current calculation mode is maintained or adjustment is required according to the state.
Specifically, the number of times of continuously receiving the response message needs to satisfy a preset number, such as 10 times, and the time interval between any two adjacent response messages needs to be not greater than a preset time difference to serve as the continuous response message, where the time difference may refer to the time of the flow monitoring period, for example, if the flow monitoring period is 10 seconds, the time difference may also be 10 seconds, and the time difference between the receiving time of the previous response message and the receiving time of the next response message needs to be not greater than 10 seconds to serve as the continuous response message. When the number of times of continuously receiving the response message exceeds 10, the target terminal is judged to be in a long-term standby state at the moment, the current flow monitoring period can be adjusted from the moment, the period is prolonged, and the time difference between the latest time and the current time is calculated based on the new flow monitoring period
In one embodiment, the above steps further include: judging whether the target terminal is restored to a normal access state according to the real-time flow data; if yes, the adjusted flow monitoring period is restored, and the time difference between the latest time and the current time is calculated based on the restored flow monitoring period at regular time.
If the real-time flow data shows that the latest time of the target terminal accessing the network is updated, the target terminal is changed from a long-term standby state to a normal access state, the current flow monitoring period can be adjusted again to restore the value to the previous value, and the time difference is calculated continuously and regularly based on the restored flow monitoring period.
The steps of adjustment and restoration can be switched in real time according to the judging result of the state of the target terminal, so that a more reasonable recovery time can be calculated with lower calculation cost.
According to the ip address resource management method provided by the embodiment of the invention, the real-time flow data of the target terminal is analyzed, so that the time difference between the latest time of the target terminal accessing the network and the current time is calculated, if the time difference is larger than the preset difference value, the target terminal does not access the network for a long time, the target terminal is possibly in a standby or off-line state, and then a reachability detection message is sent to the target terminal, if the target terminal does not return a response message, the target terminal can be judged to be off-line, at the moment, the ip address resource of the target terminal is recovered, the recovery time is accurate, and therefore, the normal use of the target terminal is not influenced, the network resource is saved, the use rate of the network resource is improved to the greatest extent, and the conditions of insufficient resource and resource waste are reduced.
