Description

IP address resource management method, cloud gateway, electronic device and storage medium

technical field

The present application relates to the field of computer technology, and in particular to an ip address resource management method, a cloud gateway, electronic equipment and a storage medium.

Background technique

In the current management of network address resources, sub-LAN is mainly used, that is, the terminal equipment is connected to the optical modem/router, and the ip address applied by the terminal is provided by the router, which belongs to the private network address. The private network address currently has dynamic ip address and static ip address Two types, the dynamic ip address is temporary and may change when the system or router is restarted, the static ip address does not change, it is configured by the terminal itself, it can remain unchanged for weeks, months or even years. At present, the dynamic ip address is maintained by the lease mechanism, that is, a fixed lease period is configured on the dhcp server. After the terminal successfully leases the ip, it can use the ip within the lease period. The static ip address is configured by the terminal itself, and the terminal can directly use this ip to access the network.

In the current ip address resource release scheme, the release timing of the dynamic ip address depends on the lease configuration of the ip address. If the terminal goes offline before the lease expires, the dynamic ip address resource will still be occupied for a period of time. Users who access the network will fail to access the network due to insufficient resources, and cannot access the network normally. The main release schemes for static ip addresses are timing clearing and traffic statistics. However, since static ip addresses are configured by users independently, using regular clearing will cause short-term network fluctuations or even disconnection risks for users, while using traffic statistics will cause large errors. The reason is that there is currently no traffic generation. It may be that the user is offline, or the user is in the standby state. If the static IP address resource is recycled directly, the normal use of the standby user may be affected.

To sum up, the current network resource management method has the technical problem of inaccurate recovery timing of ip address resources, which needs to be improved.

Those skilled in the art know that, with the evolution of the system and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems. Each will be described in detail below. It should be noted that the description sequence of the following embodiments is not intended to limit the preferred sequence of the embodiments.

Please refer to FIG. 2. FIG. 2 is a schematic flow diagram of an ip address resource management method provided in the embodiment of the present application. The method specifically includes:

S1: Obtain real-time traffic data of the target terminal.

The ip address resource management method of the present application is applied to a cloud gateway, which is a device used as a bridge between local and cloud services. The target terminal refers to any terminal that accesses the network through the cloud gateway. The target terminal needs to obtain its own ip address before accessing the network. The ip address can be a static ip address or a dynamic ip address, which is determined according to the needs of the target terminal. . Among them, if it is a static ip address, the cloud gateway will assign it to the target terminal and configure a fixed lease period. After the target terminal successfully leases the dynamic ip address, it can use the ip address within the lease period. If it is a static ip address, it will be assigned by The target terminal configures itself. For ease of description, a dynamic IP address is used as an example in this embodiment.

As shown in Figure 3, the cloud gateway in this application includes a network resource management module, a traffic statistics analysis module, and a resource detection and recovery module. The target terminal sends a dhcp message to the cloud gateway to apply for a dynamic IP address. The network resource management model of the cloud gateway responds In response to the request of the message, an unoccupied ip address is allocated to the target terminal from the address pool, and the target terminal can normally use the ip address to access the network. The target terminal will generate real-time traffic data when accessing the network, and will not generate real-time traffic data when it stops accessing the network. The acquisition, statistics and analysis of real-time traffic data are handled by the traffic statistics analysis module of the cloud gateway.

S2: According to the real-time traffic data, determine the latest time when the target terminal accesses the network, and obtain the time difference between the latest time and the current time.

As shown in Figure 3, the traffic statistics and analysis module acquires and counts real-time traffic data. If the real-time traffic data can always be counted, it means that the target terminal has been accessing the network, and the traffic statistics and analysis module only needs to continue to maintain the statistics state. If the real-time traffic data is not counted within a fixed period, the traffic statistics analysis module needs to calculate the timeout period for the target terminal to stop accessing the network, and decide whether to notify the resource detection and recovery module to perform follow-up work according to the timeout period.

Specifically, the traffic statistics analysis module collects real-time traffic data to obtain the latest time when the target terminal accesses the network, that is, the last access time, and calculates the time difference ΔT between the latest time T1 and the current time T2, that is, the timeout time. If the target terminal has been accessing the network, the latest time T1 will always change, and the time difference △T is 0. If the target terminal stops accessing the network at a certain moment, no real-time traffic data will be generated from this moment until it restarts. The real-time traffic data will be generated again when you start to access the network. The latest time T1 is the moment when the access is stopped, and the value of the time difference △T will gradually increase with the current time T.

In one embodiment, S2 specifically includes: acquiring a traffic monitoring period of the target terminal; and periodically calculating a time difference between the latest time and the current time based on the traffic monitoring period. When calculating the time difference, you can use the timing calculation method. Before calculating the time difference, you need to set the flow monitoring cycle of the target terminal. For example, 10 seconds is a cycle, and the value is stored in advance. At the same time, a timer is maintained in the cloud gateway. After the value is obtained, a calculation is performed at a fixed time in each flow monitoring cycle based on the value.

In one embodiment, the step of obtaining the traffic monitoring period of the target terminal specifically includes: determining the first access time period and the second access time period of the target terminal according to the historical traffic data of the target terminal, and the target terminal within the first access time period The offline rate of the terminal is higher than the threshold, and the offline rate of the target terminal in the second access time period is not higher than the threshold; respectively obtain the first traffic monitoring cycle of the target terminal in the first access time period and the second access time period Within the second flow monitoring period, the first flow monitoring period is shorter than the second flow monitoring period. The step of regularly calculating the time difference between the latest time and the current time based on the flow monitoring cycle specifically includes: within the first access time period, regularly calculating the time difference between the latest time and the current time based on the first flow monitoring cycle, and during the second access time period , calculating the time difference between the latest time and the current time based on the timing of the second flow monitoring period.

When setting the traffic monitoring period of the target terminal, you can set a fixed value such as 10 seconds, or analyze the network access situation of the target terminal in the historical time period, and set different periods in different periods for timing according to the analysis results Calculation, so as to quickly know whether the target terminal is offline, and save computing resources. Specifically, the historical traffic data of the target terminal in a historical time period is acquired, and the historical time period may be the past week, month or other time periods, which may be selected according to needs. Analyzing the historical traffic data, you can get the target terminal in the historical time period, which time period of the day has a higher offline rate, and which time period has a higher offline rate

The time period with a higher offline rate is set as the first visit time period, and the time period 5 with a lower offline rate is used as the second visit time period, and then the first traffic monitoring period is set for the first visit time period, which is

The second access period sets a second traffic monitoring cycle. Wherein, the duration of the first flow monitoring period is shorter than the duration 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 so on. In subsequent calculations, if the current is in the first access time period of the day

within the first traffic monitoring cycle, the timing calculation of the time difference is performed more frequently, and if the current 0 is within the second access time period of the day, then based on the second traffic monitoring cycle, it is relatively infrequent

Timing calculations of time differences are performed frequently.

Since the offline rate of the target terminal in the first access time period in the past period of time is relatively high, the recyclable probability of the ip address resource in this time period will also be relatively high, so the calculation time of each time can be calculated as

The poor cycle is set shorter to ensure that the ip address resources can be recovered quickly after the target terminal goes offline. However, due to the low offline rate of the target terminal in the second access time period in the past period of time,

Then the probability that the ip address resources do not need to be recycled during this time period will be greater, so the cycle of each calculation time difference can be set longer to achieve a balance between accurately calculating the timing of ip address resource recovery and saving computing resources.

S3: When the time difference is greater than the preset difference, send a reachability detection message to the target terminal.

0 When the time difference ΔT calculated by the flow statistical analysis module is greater than the preset difference T0, it means

The target terminal has stopped accessing the network for a long time, and may have gone offline. 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 still online.

In one embodiment, S3 specifically includes: if the target terminal is an IPV4 terminal, sending

The terminal sends an arp unicast message; if the target terminal is an IPV6 terminal, it sends an ns unicast message to the target terminal. As shown in Figure 3, the target terminal connected to the cloud gateway may be an IPV4 terminal or an IPV6 terminal. IPV4 and IPV6 are different versions of the IP protocol. It is an international common protocol. For two types of target terminals, the most suitable packets of each type of terminal are used for reachability detection. The reachability probe used in the examples of this application

The test messages all adopt the international general standard protocol, thus avoiding the incompatibility of self-defined standards, saving development time and improving development efficiency.

S4: If the response message returned by the target terminal is not received under the preset condition, recycle the ip address resource of the target terminal.

As shown in Figure 3, if the target terminal returns a response message after receiving the reachability detection message, the resource detection and recycling module determines that the target terminal is in the standby state after receiving the response message. Access to the network, but still need to reserve its ip address resources, the ip address resources will not be recycled. If the response message returned by the target terminal is not received under the preset conditions, the resource detection and recycling module determines that the target terminal is currently offline, and then directly releases its ip address resource and recycles it to the free address pool. When the management module receives an application for a new ip address, it can redistribute the ip address resources recovered this time to other terminals according to the situation, so as to improve the utilization rate of ip address resources. Wherein, the preset condition may be that the reachability detection message is successfully sent once and a certain period of time has elapsed, or the reachability detection message has been successfully sent multiple times and a certain period of time has elapsed.

In an embodiment, S43 specifically includes: when the time difference is greater than a preset difference, sending a preset number of reachability detection messages to the target terminal at a preset time interval. S4 specifically includes: reclaiming the ip address resources of the target terminal if no response message returned by the target terminal is received within a preset period of time after the last reachability detection message is sent.

When sending the reachability detection message, if it is sent only once, the target terminal may not go offline but does not receive the response message due to abnormal sending or receiving, resulting in misjudgment of the target terminal. Therefore, this application sends a preset number of reachability detection messages to the target terminal at a preset time interval, such as sending once every 0.5 seconds, and sending a total of 3 times. After the third sending is completed and the preset time period passes (such as after 1 second) still does not receive the response message, then the possibility of misjudgment is very small, it can be determined that the target terminal is offline, and its ip address resource is recycled. The specific values of the above-mentioned preset time interval, preset quantity and preset time period can be set and adjusted according to the actual scene. In this way, the probability of misjudgment can be reduced, and the accuracy of judging the recovery timing can be improved.

In one embodiment, after S3, it also includes: judging whether the target terminal is in the long-term standby state according to the number of times the response message is received continuously; The time difference from the current time.

If the target terminal is in the standby state for a long time, the time difference will be greater than the preset difference each time when the time difference is calculated regularly, and the resource detection and recovery module will be triggered to send a reachability detection message to the target terminal each time, and each time it can be sent Response messages will also be received after reachability detection messages, but the ip address resources cannot be recovered when the device is in the standby state for a long time, and the operations of frequently calculating, sending messages, and responding messages will cause waste of related resources. Therefore, whether the target terminal is in the long-term standby state can be judged according to the number of times the response message is received continuously, and then whether to maintain the current computing mode or need to be adjusted according to the state.

Specifically, the number of consecutively received response messages needs to meet the preset number, such as 10 times, and the time interval between any two adjacent response messages needs to be no greater than the preset time difference before it can be regarded as a continuous response message. In this document, the time difference can refer to the time of the flow monitoring cycle. For example, if the flow monitoring cycle is 10 seconds, the time difference can also be 10 seconds. 10 seconds can be used as a continuous response message. When the number of response messages received in a row exceeds 10 times, it is determined that the target terminal is in a long-term standby state at this time, and the current flow monitoring cycle can be adjusted from this moment to make the cycle longer, and based on the new flow monitoring cycle timing Calculate the time difference between the latest time and the current time

In one embodiment, after the above steps, it also includes: according to the real-time traffic data, judging whether the target terminal has returned to the normal access state; if so, restoring the adjusted traffic monitoring cycle, and timing based on the restored traffic monitoring cycle Calculates the time difference between the latest time and the current time.

If the real-time traffic data shows that the latest time for the target terminal to access the network has been updated, it means that the target terminal has changed from the long-term standby state to the normal access state, and the current traffic monitoring period can be adjusted again to restore the value to the previous value. And continue to regularly calculate the time difference based on the restored flow monitoring cycle.

The above steps of adjusting and restoring can be switched in real time according to the determination result of the state of the target terminal, so as to calculate a more reasonable recovery timing with a relatively small calculation cost.

It can be seen from the above embodiments that the ip address resource management method provided by the present application calculates the time difference between the latest time when the target terminal accesses the network and the current time by analyzing the real-time traffic data of the target terminal. If the time difference is greater than the preset difference, It means that the target terminal has not accessed the network for a long time, and may be in standby or offline state, and then send a reachability detection message to the target terminal. If the target terminal does not return a response message, it can be determined that it has gone offline , at this time, the ip address resource of the target terminal is recovered, and the recovery timing is more accurate, so it will not affect the normal use of the target terminal, but also save network resources, improve the utilization rate of network resources to the greatest extent, reduce the shortage of resources, Situations where resources are wasted.
