Nouns involved in the embodiments of the present application are explained as follows:

SONiC (Software for Open Networking in the Cloud): SONiC and SAI (Switch Abstraction Interface) associated therewith are two open source projects in the open cloud network area that have been dominant in recent years by Microsoft (Microsoft). The traditional network equipment can not meet the requirements of a cloud computing age cloud management platform on an open interface, software definition, modularized construction, rapid iteration and the like of a network due to the sealing, black box and locking of the traditional network equipment, microsoft dominance establishes a SONIC/SAI open source project, and aims to reconstruct open network system software based on a standard Linux kernel aiming at the requirements of Azure on the network. In order to comply with the historical trend of cloud computing, software definition and open source, microsoft does not make this system closed, private, but operates in an open, open source, community mode.

SNMP (Simple Network Management Protocol ): network devices are of a wide variety, and management interfaces (e.g., command line interfaces) provided by different device manufacturers are different, which makes network management more complex. To solve this problem, SNMP has been developed. SNMP provides a unified interface as a network management standard protocol widely used in TCP (Transmission Control Protocol )/IP (Internet Protocol, internet protocol) networks, thereby achieving unified management between heterogeneous and vendor network devices. SNMP is a standard protocol specifically designed for managing network nodes (servers, workstations, routers, switches) in an IP network, which is an application layer protocol. SNMP enables network administrators to manage network performance, discover and solve network problems, and plan network growth. The network management system knows that the network has problems by receiving random messages (and event reports) through SNMP.

MIB (Management Information Base) in SNMP: MIB in SNMP is a tree-like database, and objects managed by MIB are end nodes of a tree, each node having a unique location and a unique name. The IETF specifies that the management information base object identifier (OID, object Identifier) is uniquely specified, with the naming convention that the name of the parent node is prefixed to the name of the child node.

SNMP Agent: the SNMP Agent is an Agent process in the managed device for maintaining information data of the managed device and reporting the management data to the NMS that sent the request in response to the request from NMS (Network Management System).

In this embodiment, a method for acquiring data running on the mobile terminal is provided, and fig. 2 is a flowchart of a method for acquiring data according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:

step S202, acquiring a first request parameter according to each request time in a target time queue when the duration of data of a target data set in a target switch is not required to be acquired is greater than or equal to a first threshold, wherein the request time is the time of requesting the target switch to acquire the data of the target data set, and the first request parameter is used for indicating the frequency of requesting the target switch to acquire the data of the target data set;

Step S204, in the case that the first request parameter and the preset reference request parameter meet a preset target matching condition, caching data of the target data set in the target switch.

Fig. 3 is a schematic diagram of a data acquisition method according to an embodiment of the present application, as shown in fig. 3, a storage space 202-1 in a target switch 202 is cached with a time queue 1 (t 1, t2, t3, t 4) corresponding to the data set 1, a time queue 2 (t 5, t6, t7, t 8) corresponding to the data set 2 and a time queue 3 (t 10, t11, t12, t 13) corresponding to the data set 3 and the data set 3. The process of acquiring data in the embodiment of the present application may be explained by using the data set 3 as the target data set, but may be applied to the embodiment of the present application by not being limited thereto.

In the case where the duration of data acquisition 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, according to each request time (t 10, t11, t12, t 13) in the time queue 3 (i.e., the target time queue), acquiring a first request parameter, and in the case where the first request parameter meets a preset target matching condition with a preset reference request parameter, caching the data of the data set 3 in the storage space 202-1 of the target switch 202.

By the steps, under the condition that the data in the data set in the switch is not requested to be acquired for a long time, whether the data in the data set is to be cached in the switch can be determined according to the historical time of requesting the switch to acquire the data in the data set.

The main execution body of the above steps may be a terminal, but is not limited thereto.

The execution order of step S202 and step S204 may be interchanged, i.e. step S204 may be executed first and then step S202 may be executed.

In the technical solution provided in step S202, the target switch may include, but is not limited to include, a plurality of data sets, and the data in the target switch may be divided into a plurality of data sets according to the type of the data, or the data with higher correlation, for example: divided into CPU-related data sets, memory-related data sets, and the like.

Alternatively, in this embodiment, in a case where the length of time that 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, it may be indicated that the data in the target data set has not been requested to be acquired for a longer time, and in such a case, a first request parameter indicating the frequency of requesting the target switch to acquire the data in the target data set may be acquired, thereby determining whether or not to cache the data in the target data set in the target switch.

Optionally, in this embodiment, each data set in the target switch has a corresponding time queue for recording a time when the target switch requests to acquire data in the data set, where the time queue may be, but is not limited to, a FIFO (first in first out, first-in-first-out) queue, and the time queue may be, but is not limited to, 10, or 8, or 20, or the like, and the time queue can record at most a request time.

In one exemplary embodiment, the first request parameter may be obtained from each request time in the target time queue, but is not limited to, by: obtaining time intervals between a first request time and a second request time which are adjacent in time in the target time queue to obtain a group of time intervals, wherein the request time in the target time queue is arranged according to the time sequence of requesting the target switch to obtain the data of the target data set, and the first request time is earlier than the second request time; and acquiring the first request parameter according to the group of time intervals.

Alternatively, in this embodiment, the time interval between the first request time and the second request time that are adjacent in time in the target time queue may be acquired, for example: for the time queues 3 (t 10, t11, t12, t 13) of the data set 3, the time queues 3 may be, but are not limited to, FIFO (first in first out, first-in first-out) queues, 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 queues 3. In such a case, a set of time intervals may be obtained, but is not limited to, the difference of t11 minus t10, the difference of t12 minus t11, and the difference of t13 minus t 12.

In one exemplary embodiment, the first request parameter may be obtained from the set of time intervals by, but not limited to: and according to each time interval in the group of time intervals, acquiring the average difference of each time interval as the first request parameter.

Alternatively, in the present embodiment, the average difference between the time intervals may be acquired as the first request parameter, but is not limited to, in which case the frequency of requesting the target switch to acquire the data in the target data set may be represented by requesting the target switch to acquire the average difference between the time intervals of the data in the target data set.

Alternatively, in this embodiment, the average difference of the time intervals may be, but is not limited to, inversely proportional to the frequency of requesting the target switch to acquire the data in the target data set, that is, the greater the average difference between the intervals of the request time in the target time queue, the lower the frequency of requesting the target switch to acquire the data of the target data set, that is, the data in the target data set is not frequently requested to be acquired.

Alternatively, in this embodiment, it may be determined, but not limited to, that the first request parameter and the preset reference request parameter meet the preset target matching condition when the average difference of the respective time intervals is less than or equal to the second threshold (such as 30, or 20, or 10, etc., which is not limited in the present application).

In one exemplary embodiment, it may be determined, but is not limited to, whether data of a target data set in a target switch is frequently requested to be acquired by: acquiring a first difference value between a current detection time and the last request time in the target time queue, wherein the last request time is ordered according to time, the current detection time is the time for detecting whether the data of the target data set is determined to be cached in the target switch, and the current detection time is later than the last request time; and determining that the duration of the data of the target data set, which is not requested to be acquired, is greater than or equal to the first threshold value under the condition that the first difference value is greater than or equal to the first threshold value.

Alternatively, in this embodiment, in the case where the first difference is greater than or equal to the first threshold, it is determined that the duration in which the data of the target data set is not requested to be acquired is greater than or equal to the first threshold, and in this case, it may be indicated that the data in the target data set in the target switch has not been requested to be acquired for a longer time. In the case where the first difference is smaller than the first threshold, it is determined that the duration of time that the data of the target data set is not requested to be acquired is smaller than the first threshold, and in such a case, it may be indicated that the data in the target data set in the target switch is still frequently requested to be acquired.

Alternatively, in this embodiment, the above-mentioned data set 3 may be taken as a target data set, and the time queue 3 corresponding to the data set 3 is taken as a target time queue as an example, and 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 of the present application may be explained and illustrated, which is not limited to be applicable to the embodiment of the present application.

The time queue 3 (t 10, t11, t12, t 13) of the data set 3, the time queue 3 may be, but is not limited to, a FIFO (first in first out, 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, and in the case that the difference (i.e., the first difference) between the current detection time and t13 is greater than or equal to a first threshold (may be, but is not limited to, 600s, or 700s, or 500s, etc.), it is determined that the duration of the data set 3 that is not requested to be acquired is greater than or equal to the first threshold.

In case the difference between the current detection time and t13, i.e. the first difference, is smaller than a first threshold value (which may be, but not limited to, 600s, or 700s, or 500s, etc., without being limited in this application), it is determined that the duration of the data set 3 not being requested to be acquired is smaller than the first threshold value.

In the technical solution provided in step S204, in the case that the first request parameter and the preset reference request parameter meet the preset target matching condition, it may indicate that the data of the target data set in the target switch is frequently requested to be acquired, in this case, but not limited to, the data of the target data set may be cached in the target switch in advance, so that in the case that the data of the target data set is requested to be acquired, the required data may be directly read from the cached data of the target data set, thereby improving the data acquisition efficiency.

Optionally, in this embodiment, by pre-caching the data of the data sets that are frequently requested to be acquired in the target switch, on one hand, caching the data of all the data sets (for example, data of some data sets that are frequently not 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, the data of the data set which is frequently requested to be acquired is cached in the target switch in advance, so that the data which is frequently requested to be acquired can be ensured to be frequently updated, and the updating efficiency of the data is improved.

In one exemplary embodiment, the data of the target data set may be, but is not limited to, cached in the target switch by: invoking a set of objective functions corresponding to the objective data set, wherein each data of the objective data set has a corresponding function, and each function in the set of objective functions is used for collecting a plurality of data of the objective data set in the objective switch; and caching the calling result of each function in the group of target functions in the target switch.

Optionally, in this embodiment, each data of the target data set may, but is not limited to, have different acquisition manners, and may, but is not limited to, implement acquisition of each data in the target data set by calling a set of update functions corresponding to the target data set, where each data of the target data set has a corresponding update function; the results of the call to each update function in the set of updates may be, but are not limited to, cached in the target switch.

In one exemplary embodiment, the data of the target data set may be acquired, but is not limited to, by: acquiring a target data request at a target request time, wherein the target data request is used for requesting the target switch to acquire target data, and the target data request carries a data identifier of the target data; responding to the target data request, and determining a data set to which data corresponding to the data identifier of the target data belongs as the target data set; and acquiring the target data from the data of the target data set cached in the target switch.

Optionally, in this embodiment, in the case that the target data request is acquired at the target request time, it may indicate that it is desired to request the target data from the target switch, and in such a case, it may be, but is not limited to, in response to the target data request, determine, as the target data set, a data set to which data corresponding to the data identifier of the target data belongs, and acquire the target data from the data of the target data set cached in the target switch. By the method, target data which is expected to be acquired are directly read from the data of the target data set cached in the target switch, the situation that the data which is expected to be acquired are acquired in real time under the condition that the target data request is acquired is avoided, and the data acquisition efficiency is greatly improved.

In one exemplary embodiment, the time at which the target request was obtained may be, but is not limited to, recorded in a target time queue by: and recording the target request time 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.

Alternatively, in this embodiment, the target time queue may be, but not limited to, a FIFO (first in first out, first-in first-out) queue, and the target request time may be, but not limited to, recorded in the target time queue according to the chronological order of the requests to the target switch for the data of the target data set. So that a request parameter indicating a frequency of requesting the target switch to acquire the data of the target data set can be acquired in a case where it is required to determine whether or not to cache the data of the target data set in the target switch next time according to the respective request times recorded in the target time queue.

In order to better understand the above process of reading the data in the target switch cache and recording the time of obtaining the request, the method for obtaining the data in the embodiment of the present application is explained and illustrated below with reference to an alternative embodiment, which may be, but not limited to, applied to the embodiment of the present application.

Fig. 4 is a schematic diagram of a data acquisition process according to an embodiment of the present application, as shown in fig. 4, in which data of a plurality of data sets and a time queue corresponding to each data set are stored in a storage space 202-1 of a target switch 202, it may be explained and illustrated by taking a data set 3 as a target data set and a time queue 3 corresponding to the data set 3 as a target time queue, for example.

The time queue 3 originally records (t 10, t11, t12, t 13), t10 is earlier than t11, t11 is earlier than t12, t12 is earlier than t13, and the target switch 202 acquires a target data request at a target request time t14, where the target data request is used for requesting the target switch 202 to acquire data 3 (i.e., target data), and the target data request carries a data identifier of the data 3; in such a case, the switch may determine, in response to the target data request, a data set 3 to which the data corresponding to the data identifier of the data 3 belongs as a target data set; the data 3 is acquired from the data of the data set 3 cached in the storage space 202-1 of the target switch 202, the acquired data 3 is returned, and the target request time t14 is recorded in the time queue 3 according to the time sequence of requesting the target switch 202 to acquire the data of the data set 3, wherein the last request time in the time queue 3 is the target request time t14.

In order to better understand the above process of reading the data in the cache of the target switch and recording the time of acquiring the request, the target switch may be, but is not limited to, a target switch running with the SONiC (Software for Open Networking in the Cloud) system, the target switch is managed through SNMP protocol, the target switch needs to be accessed after a period of time, the target switch is periodically requested to acquire the data for management, the NMS requests the target switch to acquire the data, the SNMP Agent responds to the request of the NMS and returns the data requested by the NMS to explain and explain the method of acquiring the data in the embodiments of the present application, which may be, but is not limited to, applied to the embodiments of the present application. The method for acquiring data in the embodiment of the present application may be implemented, but is not limited to, by the following steps:

Step 1: a mix_base class includes an update function, a length 10 timestamp FIFO queue, a flag start_update, default to False, which indicates that no data is collected.

Step 2: creating a class for each MIB, inheriting the class in step 1, that is, after inheriting the class in step 1, each class created in step 2 has the same flag bit (default is False) as the mib_base class generated in step 1, the same length of time stamp FIFO queue and update function, and realizes the update function according to the requirement of the MIB, and updates the data required by the MIB when the update function is called.

It should be noted that, a mib corresponds to a data set (e.g., 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 (the queue is used to record a time for requesting to obtain data corresponding to the instance object from the switch), and each mib instance object corresponds to a manner of collecting all data in the data set.

Step 3: a set of tab instances is used to store all tab instance objects.

Step 4: a factory, according to the OID of MIB, using class in step 2 to produce a correspondent instance object for all MIBs, and adding it into the collection of step 3.

Step 5: a data updating thread traverses the set of the step 3, creates a thread for each instance MIB object, periodically checks the start_update flag bit, calls an update function under the condition that the start_update flag bit is True, and collects the data of the data set in the switch; in the case where the start_update flag bit is False, the MIB instance is skipped.

Step 6: in the case that the SNMP agent in the switch (i.e., the target switch) receives the get or get_next request (i.e., the target data request described above), the collection in step 3 is traversed, the corresponding MIB instance object (i.e., the target data collection described above) is found according to the OID (i.e., the data identifier of the target data described above), and the time when the get or get_next request is received is added to the timestamp queue (i.e., the target time queue described above).

Step 7: a thread traverses the set of step 3 to periodically check the time stamp queue in the MIB instance object, if the difference between the last time request time in the time stamp queue and the current detection time is more than 600 seconds (namely the first threshold value), the time stamp postamble in the queue is subtracted from the antecedent (namely the time interval between the first request time and the second request time which are adjacent in time) to obtain all time intervals (namely a group of time intervals), then the average difference is calculated, if the average difference is not more than 30, the MIB instance object is considered to have periodic access, and the start_update flag bit is set as True; otherwise set to False. If the difference between the last request time in the timestamp queue and the current detection time is less than 600 seconds, the MIB instance object may be indicated to have periodic access, and the start_update flag bit is set to True.

Through the above embodiment, if one MIB instance object has no get or get_next request for a period of time, the operation of updating the data of the MIB instance object in the switch is stopped, thereby saving system resources of the switch. In addition, the data of the data set in the switch is updated based on the MIBs, a thread is created for each MIB, when a user uses SNMP to manage equipment, some MIBs are usually accessed in a targeted and periodic mode, other MIBs are not concerned, and fine-grained allocation of switch resources is realized based on the MIB updated data.

From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment. Based on such understanding, the technical solutions of the embodiments of the present application may be essentially or portions contributing to the prior art may be embodied in the form of a software product stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk), including several instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the methods described in the embodiments of the present application.
