[0026] The terms involved in the embodiments of the present application are explained as follows:

[0027] SONiC (Software for Open Networking in the Cloud): SONiC and its companion SAI (Switch Abstraction Interface) are two open source projects in the field of open cloud networking led by Microsoft in recent years. Traditional network devices are completely unable to meet the needs of cloud management platforms in the cloud computing era, such as open interface, software definition, modular construction, and rapid iteration. Microsoft led the establishment of the SONiC / SAI open source project, aiming to rebuild an open network system software based on the standard Linux kernel for the needs of Azure for network. In order to comply with the historical trend of cloud computing, software definition, and open source, Microsoft did not make this system closed and private, but operated in an open, open source, and community mode.

[0028] SNMP (Simple Network Management Protocol): There are various types of network devices, and the management interfaces (such as command line interfaces) provided by different device manufacturers are different, which makes network management more complex. To solve this problem, SNMP was born. As a widely used network management standard protocol in TCP / IP networks, SNMP provides a unified interface, thereby realizing the unified management of network devices of different types and manufacturers. SNMP is a standard protocol designed specifically for managing network nodes (servers, workstations, routers, switches) on IP networks. It is an application layer protocol. SNMP enables network administrators to manage network performance, discover and resolve network problems, and plan network growth. Network management systems receive random messages (and event reports) through SNMP to learn about network problems.

[0029] MIB (Management Information Base) in SNMP: MIB in SNMP is a tree database, the object managed by MIB is the end node of the tree, each node has a unique position and a unique name. IETF specifies that the OID (Object Identifier) uniquely specifies the management information base object identifier, and the naming rule is that the name of the parent node is prefixed to the name of the child node.

[0030] SNMP Agent: SNMP Agent is an agent process in the managed device, which is used to maintain the information data of the managed device and respond to the request from NMS (Network Management System) to report the management data to the NMS sending the request.

[0031] In the embodiment, a data acquisition method running on the mobile terminal is provided, Figure 2 is a flowchart of the data acquisition method according to the embodiment of the application, as Figure 2 shown, the flow includes the following steps:

[0032] Step S202, in the case where the time length during which the data of the target data set in the target switch is not requested to be acquired is greater than or equal to the first threshold value, the first request parameter is acquired according to each request time in the target time queue, wherein the request time is the time of requesting to acquire the data of the target data set in the target switch, and the first request parameter is used to indicate the frequency of requesting to acquire the data of the target data set in the target switch;

[0033] Step S204, in the case where the first request parameter and the preset reference request parameter satisfy the preset target matching condition, the data of the target data set in the target switch is cached.

[0034] Figure 3 is a schematic diagram of a data acquisition method according to an embodiment of the application, as Figure 3 shown, the storage space 202-1 in the target switch 202 caches the data set 1 and the time queue 1 (t1, t2, t3, t4) corresponding to the data set 1, the data set 2 and the time queue 2 (t5, t6, t7, t8) corresponding to the data set 2, and the data set 3 and the time queue 3 (t10, t11, t12, t13) corresponding to the data set 3. The data acquisition process in the embodiment of the application can be explained and described by taking the data set 3 as the target data set, which can be applied to the embodiment of the application.

[0035] In a case where the time length during which the data of the data set 3 (i.e., the target data set) in the target switch 202 is not requested to be acquired is greater than or equal to the first threshold, the first request parameter is acquired according to the request times (t10, t11, t12, t13) in the time queue 3 (i.e., the target time queue), and in a case where the first request parameter and the preset reference request parameter satisfy the preset target matching condition, the data of the data set 3 is cached in the storage space 202-1 of the target switch 202.

[0036] Through the above steps, in a case where the data in a data set in a switch is not requested to be acquired for a long time, whether the data in the data set is cached in the switch can be determined according to the historical time when the data in the data set is requested to be acquired from the switch. In this way, the data in the data set that is frequently requested to be acquired is cached in the switch, so that the problem that the storage space occupied by the data in the switch is large can be solved, and the effect of reducing the storage space occupied by the data in the switch is achieved.

[0037] The execution subject of the above steps can be a terminal or the like, but is not limited thereto.

[0038] The execution order of steps S202 and S204 can be interchanged, i.e., step S204 can be executed first, and then step S202 can be executed.

[0039] In the technical solution provided in the above step S202, the target switch can include but is not limited to a plurality of data sets. The data in the target switch can be divided into a plurality of data sets in a manner such as a type of data or data with high correlation, etc. For example, the data can be divided into a CPU-related data set, a memory-related data set, etc.

[0040] Optionally, in this embodiment, in a case where the time length during which the data of the target data set in the target switch is not requested to be acquired is greater than or equal to the first threshold, it can be indicated that the data in the target data set has not been requested to be acquired for a long time. In this case, the first request parameter indicating the frequency of requesting the data in the target data set from the target switch can be acquired, and then it is determined whether the data in the target data set is cached in the target switch.

[0041] Optionally, in this embodiment, each data set in the target switch has a corresponding time queue for recording the time when the data in the data set is requested to be acquired from the target switch. The time queue can be but is not limited to a FIFO (first in first out) queue. The maximum number of request times that can be recorded by the time queue can be but is not limited to 10, or 8, or 20, etc., which is not limited in the present application.

[0042] In an exemplary embodiment, the first request parameter can be obtained according to each request time in the target time queue, but not limited to, by: obtaining a set of time intervals between time intervals between a first request time and a second request time in the target time queue, wherein each request time in the target time queue is arranged in chronological order of time when the target switch is requested to obtain data in the target data set, and the first request time is earlier than the second request time; and obtaining the first request parameter according to the set of time intervals.

[0043] Optionally, in this embodiment, the time interval between the first request time and the second request time in the target time queue can be obtained, but not limited to, such as: for the time queue 3 (t10, t11, t12, t13) of the data set 3, the time queue 3 can be but not limited to a FIFO (first in first out) queue, that is, t10 is earlier than t11, t11 is earlier than t12, t12 is earlier than t13, and t13 is the last request time recorded in the time queue 3. In this case, the difference between t11 and t10, the difference between t12 and t11, and the difference between t13 and t12 can be obtained, but not limited to, to obtain a set of time intervals.

[0044] In an exemplary embodiment, the first request parameter can be obtained according to the set of time intervals, but not limited to, by: obtaining the average difference of each time interval in the set of time intervals as the first request parameter.

[0045] Optionally, in this embodiment, the average difference of each time interval can be obtained as the first request parameter, but not limited to, in which case, the average difference between the time intervals when the target switch is requested to obtain data in the target data set can be used to represent the frequency of requesting the target switch to obtain data in the target data set.

[0046] Optionally, in this embodiment, the average difference of the time interval can be inversely proportional to the frequency of requesting the target switch to obtain data in the target data set, that is, the larger the average difference between the request times in the target time queue, the lower the frequency of requesting the target switch to obtain data in the target data set, that is, the data in the target data set is not frequently requested to be obtained.

[0047] Optionally, in the embodiment, the first request parameter is determined to satisfy the preset target matching condition with the preset reference request parameter, but not limited to, in the case that the average difference of each time interval is less than or equal to a second threshold value (such as 30, or 20, or 10, etc., which is not limited in the application).

[0048] In an exemplary embodiment, whether the data of the target data set in the target switch is frequently requested to be acquired can be determined, but not limited to, by the following way: obtaining a first difference value between a current detection time and a last request time in the target time queue in chronological order, wherein the current detection time is the time for detecting whether the data of the target data set in the target switch is determined to be cached, and the current detection time is later than the last request time; in the case that the first difference value is greater than or equal to the first threshold value, it is determined that the data of the target data set is not requested to be acquired for a time period greater than or equal to the first threshold value.

[0049] Optionally, in the embodiment, in the case that the first difference value is greater than or equal to the first threshold value, it is determined that the data of the target data set is not requested to be acquired for a time period greater than or equal to the first threshold value, in which case it can be indicated that the data in the target data set in the target switch has not been requested to be acquired for a long time. In the case that the first difference value is less than the first threshold value, it is determined that the data of the target data set is not requested to be acquired for a time period less than the first threshold value, in which case it can be indicated that the data in the target data set in the target switch is still frequently requested to be acquired.

[0050] Optionally, in the embodiment, the process of determining whether the data of the target data set in the target switch is frequently requested to be acquired in the embodiment can be explained and described, but not limited to, by taking the data set 3 as the target data set and the time queue 3 corresponding to the data set 3 as the target time queue, which can be applied to the embodiment, but not limited to.

[0051] The time queue 3 (t10, t11, t12, t13) of the data set 3 can be, but not limited to, a FIFO (first in first out) queue, t10 is earlier than t11, t11 is earlier than t12, t12 is earlier than t13, t13 is the last request time recorded in the time queue 3, in the case that the difference (i.e. the first difference value) between the current detection time and t13 is greater than or equal to the first threshold value (which can be, but not limited to, 600s, or 700s, or 500s, etc., which is not limited in the application), it is determined that the data of the data set 3 is not requested to be acquired for a time period greater than or equal to the first threshold value.

[0052] In a case where a difference between the current detection time and t13 (i.e., a first difference) is less than a first threshold (which can be but is not limited to 600s, or 700s, or 500s, etc., and the present application does not limit this), it is determined that a duration for which data of the data set 3 is not requested to be acquired is less than the first threshold.

[0053] In the technical solution provided in step S204, in a case where the first request parameter and the preset reference request parameter satisfy a preset target matching condition, it can be indicated that data of the target data set in the target switch is frequently requested to be acquired, and in such a case, the data of the target data set can be but is not limited to pre-cached in the target switch, so that in a case where the data of the target data set is requested to be acquired, the required data can be directly read from the cached data of the target data set, and the data acquisition efficiency is improved.

[0054] Optionally, in the present embodiment, by pre-caching data of frequently requested data sets in the target switch, on one hand, caching of data of all data sets (such as data of some data sets that are not frequently accessed or even not accessed) in the target switch is avoided, and in this way, the utilization rate of the storage space in the target switch is improved. On the other hand, pre-caching of data of frequently requested data sets in the target switch can ensure that frequently requested data is frequently updated, and the update efficiency of these data is improved.

[0055] In an exemplary embodiment, the data of the target data set can be but is not limited to cached in the target switch by: calling a group of target functions corresponding to the target data set, wherein each data of the target data set has a corresponding function, and each function in the group of target functions is used to collect a plurality of data of the target data set in the target switch; and caching a calling result of each function in the group of target functions in the target switch.

[0056] Optionally, in the present embodiment, each data of the target data set can but is not limited to have a different collection manner, and the collection of each data of the target data set can be but is not limited to implemented by calling a group of update functions corresponding to the target data set, wherein each data of the target data set has a corresponding update function; and a calling result of each update function in the group of update functions can be but is not limited to cached in the target switch.

[0057] In an exemplary embodiment, the data of the target data set can be acquired in the following manner, but not limited thereto: at a target request time, a target data request is acquired, wherein the target data request is used to request the target switch to acquire target data, and the target data request carries a data identifier of the target data; in response to the target data request, a data set to which the data corresponding to the data identifier of the target data belongs is determined as the target data set; and the target data is acquired from the data of the target data set cached in the target switch.

[0058] Optionally, in the embodiment, in the case that the target data request is acquired at the target request time, it can be indicated that the target data is expected to be requested from the target switch, and in this case, the data set to which the data corresponding to the data identifier of the target data belongs can be determined as the target data set in response to the target data request, and the target data can be acquired from the data of the target data set cached in the target switch. In this way, the target data expected to be acquired can be directly read from the data of the target data set pre-cached in the target switch, and real-time collection of the data expected to be acquired is avoided in the case that the target data request is acquired, so that the data acquisition efficiency is greatly improved.

[0059] In an exemplary embodiment, the target request time can be recorded in the target time queue in the following manner, but not limited thereto: the target request time is recorded in the target time queue according to the time sequence of requesting the target switch to acquire the data of the target data set, wherein the last request time in the target time queue is the target request time.

[0060] Optionally, in the embodiment, the target time queue can be a first in first out (FIFO) queue, and the target request time can be recorded in the target time queue according to the time sequence of requesting the target switch to acquire the data of the target data set. In this way, the request parameter used to represent the frequency of requesting the target switch to acquire the data of the target data set can be acquired according to the request times recorded in the target time queue in the case that it is next time to determine whether the data of the target data set is cached in the target switch.

[0061] In order to better understand the above processes of reading the data cached in the target switch and recording the request times, the data acquisition method in the embodiments of the present application is explained and described below in combination with optional embodiments, which can be applied to the embodiments of the present application, but not limited thereto.

[0062] Figure 4is a schematic diagram of a data acquisition process according to an embodiment of the present application, as shown Figure 4 The storage space 202-1 of the target switch 202 stores data of a plurality of data sets and a time queue corresponding to each data set. For example, the data set 3 is taken as a target data set, and the time queue 3 corresponding to the data set 3 is taken as a target time queue.

[0063] The time queue 3 originally records (t10, t11, t12, t13), t10 is earlier than t11, t11 is earlier than t12, and t12 is earlier than t13. The target switch 202 acquires a target data request at the target request time t14. The target data request is used to request the target switch 202 to acquire the data 3 (i.e., target data). The target data request carries the data identifier of the data 3. In this case, the switch can respond to the target data request, determine the data set 3 to which the data corresponding to the data identifier of the data 3 belongs as a target data set, acquire the data 3 from the data of the data set 3 cached in the storage space 202-1 of the target switch 202, return the acquired data 3, and record the target request time t14 in the time queue 3 according to the time sequence of the target switch 202 requesting to acquire the data of the data set 3. The last request time in the time queue 3 is the target request time t14.

[0064] In order to better understand the above process of reading data in the cache of the target switch and recording the request time, the data acquisition method in the embodiment of the present application is explained and described by taking the target switch running the SONiC (Software for Open Networking in the Cloud) system as an example, the target switch is managed by the SNMP protocol, the target switch needs to be accessed every certain period of time, and the data is periodically requested to be acquired for management. The NMS requests the target switch to acquire data, and the SNMP Agent responds to the request of the NMS and returns the data requested by the NMS. The data acquisition method in the embodiment of the present application can be applied to the embodiment of the present application. The data acquisition method in the embodiment of the present application can be implemented by the following steps:

[0065] Step 1: An mib_base class includes an update function, a time stamp FIFO queue with a length of 10, and a flag bit start_update, which is False by default, indicating that no data is collected.

[0066] Step 2: Create a class for each MIB, inherit the class in Step 1, that is, each class created in Step 2, after inheriting the class in Step 1, has the same flag bit (default False), the same length of timestamp FIFO queue, and the update function as the mib_base class generated in Step 1, and implements the update function as needed by the MIB. When the update function is called, the data required by the MIB is updated.

[0067] It should be noted that one mib corresponds to one data set (such as a memory-related data set, a CPU-related data set, etc.), each mib has a mib instance object, each mib instance object corresponds to a FIFO time queue (which is used to record the time of requesting the data corresponding to the instance object from the switch), and each mib instance object corresponds to the collection method of all data in the data set.

[0068] Step 3: A set of mib instances is used to store all mib instance objects.

[0069] Step 4: A factory is used to produce a corresponding instance object for all MIBs using the class in Step 2 according to the OID of the MIB, and add it to the set in Step 3.

[0070] Step 5: An update data thread is used to traverse the set in Step 3, create a thread for each instance MIB object, periodically check the start_update flag, and in the case of start_update flag being True, call the update function to collect data in the switch; in the case of start_update flag being False, skip the MIB instance.

[0071] Step 6: In the case that the SNMP agent in the switch (i.e. the target switch) receives a get or get_next request (i.e. the target data request described above), traverse the set in Step 3, find the corresponding MIB instance object (i.e. the target data set described above) according to the OID (i.e. the data identifier of the target data described above), and add the time of receiving the get or get_next request to the timestamp queue (i.e. the target time queue described above).

[0072] Step 7: One thread, traversing the set of step 3, periodically checks the time stamp queue in the MIB instance object, if the difference between the last request time in the time stamp queue and the current detection time is greater than 600 seconds (i.e. the first threshold value), subtracts the last item from the first item in the time stamp queue (i.e. the time interval between the first request time and the second request time in time), obtains all time intervals (i.e. a set of time intervals), then calculates the average difference, if the average difference is not greater than 30, it is considered that the MIB instance object is periodically accessed, and the start_update flag is set to True; otherwise, it is set to False. If the difference between the last request time in the time stamp queue and the current detection time is less than 600 seconds, it can be indicated that the MIB instance object is periodically accessed, and the start_update flag is set to True.

[0073] Through the above embodiment, if there is no get or get_next request for a MIB instance object within a period of time, the operation of updating the data of the MIB instance object in the switch is stopped, and the system resources of the switch are saved. In addition, the data of the data set in the switch is updated based on the MIB, a thread is created for each MIB, and when a user uses SNMP to manage a device, the user usually has targeted and periodic access to some MIBs, and other MIBs are not concerned.
