When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
As described in the background, the following technical problems often occur in the discovery process of the internet of things: on the premise that the detection stage is executed only once in each detection period, packet loss may occur in the sending process or the receiving process of the detection packet in the detection stage, and the discovery result of the intelligent terminal device of the internet of things is inaccurate due to the packet loss. In order to solve the technical problem, the embodiment of the present application provides a "two-stage device discovery scheme". Here, the "two-stage device discovery scheme" may be implemented by performing two detection stages (respectively referred to as a first detection stage and a second detection stage) in one detection cycle, where the second detection stage is determined by analyzing the intelligent terminal device of the internet of things discovered in the first detection stage. Through the two-section type equipment discovery scheme, the intelligent terminal equipment of the internet of things which is not discovered in the first detection stage can be further discovered, and the accuracy of the discovery result of the intelligent terminal equipment of the internet of things and the discovery efficiency of the intelligent terminal equipment of the internet of things are greatly improved.
The method provided by the embodiment of the application is described by the following figure 1:
referring to fig. 1, fig. 1 is a flowchart of a method provided in an embodiment of the present application. The method is applied to the detection device. Optionally, the detection device here may be a firewall device, a security gateway device, and the like, and this embodiment is not particularly limited.
As shown in fig. 1, the process may include the following steps:
In this embodiment, the probing devices will uniformly send probing packets in bulk for a period of time (e.g. 0.5 s) from the beginning of the probing period. Based on this, as an example, the present embodiment may use a period of time (for example, 0.5 seconds) from the start time (denoted as T1) of the detection period as the first detection phase in the detection period. It should be noted that, the limitation of the first detection phase is only described by way of example, and may also be another period of time in the detection period, and this embodiment is not limited to this.
In this embodiment, once the probing device initiates the first probing phase within the probing period, it means that the probing device will send at least one probing packet within the first probing phase. Here, the detection package is used for detecting and discovering the intelligent terminal equipment of the internet of things, and different detection packages detect and discover different intelligent terminal equipment of the internet of things. Optionally, in this embodiment, the probe packet may carry the destination IP address. Here, the destination IP address is an IP address of the internet-of-things intelligent terminal device to be found. The detection packets are used for detecting and discovering the intelligent terminal equipment of the internet of things corresponding to the target IP addresses carried by the detection packets, and different detection packets carry different target IP addresses and are used for detecting and discovering different intelligent terminal equipment of the internet of things.
As an embodiment, in the first probing phase, the probing device may construct a probing packet according to the obtained IP address set (which may be a C segment, a sequence, etc.) of the device to be probed. The target IP address carried by each constructed detection packet is one IP address in an IP address set and is used for detecting and discovering the intelligent terminal equipment of the Internet of things corresponding to the target IP address carried by the detection packet, and the target IP addresses carried by different detection packets are different and are used for detecting and discovering different intelligent terminal equipment of the Internet of things. It should be noted that, the probe packet may further carry a destination port, a SEQUENCE number (SEQUENCE _ NUM), a source IP address (IP address of the probe device), a source port (port on the probe device that sends the probe packet), and the like in addition to the destination IP address, and this embodiment is not particularly limited.
In this embodiment, the probe packet may be a probe packet in a TCP probing manner (referred to as a TCP probe packet for short). In this embodiment, the probe packet may be a probe packet in an ICMP or UDP system, but this embodiment is not particularly limited.
Optionally, in this embodiment, the first specified time period is set based on a purpose of rapidly detecting and discovering the intelligent terminal device of the internet of things, and as an embodiment, it may be specifically represented by the following formula 1:
the sending time of the detection packet (marked as T1_ 1) to T1_1+ (T _ Timeout 1/N) (formula 1)
As an embodiment, the first specified time period may be a fixed time period for the first probing phase, and on this premise, T1_1 in the above formula 1 may be unified as the time of the first probing packet sent by the first probing phase, and may of course be the time of the last probing packet sent by the first probing phase, and the like, and this embodiment is not limited in particular. As another embodiment, the first specified time period may also be a time period after each probe packet is sent, in this case, for each probe packet sent in the first probing phase, there is a corresponding first specified time period, and T1_1 in the above formula 1 is the time of the probe packet sent in the first probing phase.
In the above formula 1, T _ Timeout represents a total detection Timeout preset for the whole detection period, which can be set according to actual requirements. In the above formula 1, N may be set according to an actual requirement, which is generally greater than 1, so as to obtain the first type of information of the internet of things intelligent terminal device detected and found in the first detection stage before the preset Timeout T _ Timeout.
In this embodiment, the first type of information of the intelligent terminal device of the internet of things includes device information corresponding to the intelligent terminal device of the internet of things that meets a first condition, where the first condition is: and returning a valid response packet for the detection packet in the first detection stage. How to obtain the first type of internet-of-things intelligent terminal device information detected and discovered in the first detection stage according to the monitored response packets has many implementation manners, such as: monitoring response packets returned by the intelligent terminal equipment of the internet of things aiming at the detection packets in real time within a first specified time period, and analyzing the response packets layer by layer aiming at each monitored response packet to obtain data packet information (such as a source IP address, a source port, a source MAC address, a destination IP address, a destination port, a destination MAC address, an ACK value and the like) carried by the response packets. And then, judging whether the response packet is a valid packet according to an ACK value in the packet information, wherein if the ACK value is the sum of a SEQUENCE number (SEQUENCE _ NUM) in a detection packet corresponding to the response packet and 1, the response packet is indicated to be a valid packet, and otherwise, the response packet is discarded. Once the response packet is judged to be a valid data packet, the internet of things intelligent terminal device information (such as a source IP address, a source port, a source MAC address, and the like) related to the internet of things intelligent terminal device in the data packet information is acquired. Taking the information of the intelligent terminal device of the internet of things as a source IP address (denoted as IP _ 1), a source Port (denoted as Port _ 1), and a source MAC address (denoted as MAC _ 1), the information of the intelligent terminal device of the internet of things can be expressed as follows: IP _ 1: [ Port _1, MAC _1 ]. By analogy, the final information of the first type of internet-of-things intelligent terminal equipment can be represented as follows:
{IP_1：[Port_1、MAC_1]
IP_2：[Port_2、MAC_2]
……
IP_N：[Port_N、MAC_N]}
Here, the second detection phase may be a period of time (e.g., 0.5 seconds, etc.) beginning at the end time (denoted as T1_1_ end) of the first designated period of time. Alternatively, as an embodiment, T1_1_ Ent here may be a first specified time period after the last probe packet in the first probe phase is sent.
As an embodiment, there are many implementation manners of how the detection device determines, according to the obtained information of the first type of internet of things smart terminal device, to further perform the second detection phase in the detection period, and one of the manners is described below by way of example.
As described in step 103, once the detection device determines, according to the obtained information of the first type of internet-of-things smart terminal device, that a second detection phase is to be executed in the detection period, the second detection phase is initiated in the detection period (i.e., at least one detection packet is sent to detect an internet-of-things smart terminal device that is not detected in the first detection phase). The step 103 finally realizes that the probing phase is executed twice in one probing cycle.
104, monitoring response packets returned by the intelligent terminal equipment of the internet of things for the detection packets by the detection equipment in a second specified time period after the detection packets are sent, and acquiring second type of information of the intelligent terminal equipment of the internet of things discovered through detection in the second detection stage according to the monitored response packets; and taking the first type of Internet of things intelligent terminal equipment information and the second type of Internet of things intelligent terminal equipment information as detection discovery results of the detection period and outputting the detection discovery results.
Optionally, in this embodiment, the second specified time period is set based on a purpose of finally detecting the internet of things intelligent terminal device that is not found in the first detection stage, and may specifically be detection packet sending time (denoted as T1_ 2) — T1_2+ (T _ Timeout (N-1)/N) sent in the second detection stage. For one embodiment, T1_2 may be the time of the first probe packet sent in the second probing phase. T _ Timeout, N is as described above.
Alternatively, as can be seen from the above description about the first and second specified time periods, the sum of the durations of the first and second specified time periods is equal to the preset Timeout time T _ Timeout. That is to say, in this embodiment, the delay times of the snoop response packets used in the detection discovery in the first detection stage and the second detection stage are not the preset total delay time T _ Timeout, and the sum of the delay times of the snoop response packets used in the detection discovery in the two detection stages is the preset total delay time T _ Timeout. As to the size of the duration of the first specified time period and the duration of the second specified time period, the embodiment is not particularly limited, and may be: such as the duration of the first specified time period being less than the duration of the second specified time period, the duration of the first specified time period being greater than the duration of the second specified time period, even the duration of the first specified time period being equal to the duration of the second specified time period, etc.
In this embodiment, the second type of information of the intelligent terminal device of the internet of things may include device information corresponding to the intelligent terminal device of the internet of things that satisfies a second condition, where the second condition is: and returning a valid response packet for the detection packet in the second detection stage. As to how to obtain the second type of information of the intelligent terminal device of the internet of things discovered through the second detection stage according to the monitored response packets, reference may be made to the description of determining the first type of information of the intelligent terminal device of the internet of things in step 102, which is not described here.
After the second type of internet of things intelligent terminal device information is obtained through the second detection stage, as described in step 104, the first type of internet of things intelligent terminal device information and the second type of internet of things intelligent terminal device information can be directly used as detection discovery results of the detection period and output, and the detection of two different stages through one detection period discovers the internet of things intelligent terminal device, so that the problem that the discovery results of the internet of things intelligent terminal device are inaccurate due to network jitter and packet loss when the detection period is initiated once can be avoided, and the accuracy of the discovery results of the internet of things intelligent terminal device and the device discovery efficiency are effectively improved.
Thus, the flow shown in fig. 1 is completed.
As can be seen from the flow shown in fig. 1, in the embodiment of the application, the first detection stage is executed in one detection period through the "two-stage device discovery scheme", and the second detection stage is executed twice in total, so as to further discover the intelligent terminal device of the internet of things that is not discovered in the first detection stage, thereby avoiding the inaccuracy of the discovery result of the intelligent terminal device of the internet of things caused by network jitter packet loss when the detection stage is initiated in one detection period, and effectively improving the accuracy of the discovery result of the intelligent terminal device of the internet of things and the device discovery efficiency.
How to determine to execute the second detection stage in the detection period according to the obtained information of the first type of internet of things intelligent terminal device in the step 103 is described below:
referring to fig. 2, fig. 2 is a flowchart illustrating the determination of performing the second detection phase in step 103 according to the embodiment of the present application. As shown in fig. 2, the process may include the following steps:
Alternatively, in this embodiment, the historical probe record may be stored in the configured historical surviving device list dictionary (IP _ ALL _ HISTORY). For IP _ ALL _ HISTORY, the method is used for recording the information of the intelligent terminal equipment of the Internet of things, which is detected and found before the detection period. The format of the IP _ ALL _ HISTORY record of the information of the intelligent terminal device of the internet of things can be referred to the format of the information of each intelligent terminal device of the internet of things in the above first type of information of the intelligent terminal device of the internet of things, and is not described herein again.
Based on this, in this step 201, obtaining the third type of internet of things intelligent terminal device information detected and discovered before the detection period from the configured historical detection record may include: and acquiring ALL the information of the internet of things intelligent terminal equipment recorded by the IP _ ALL _ HISTORY from the IP _ ALL _ HISTORY, and taking the acquired ALL the information of the internet of things intelligent terminal equipment as the third type of information of the internet of things intelligent terminal equipment.
It should be noted that, in this embodiment, IP _ ALL _ store is initially empty, and is updated according to the probing discovery result in this probing period before each probing period ends, and how to update IP _ ALL _ store will be described below, which is not described herein for the sake of brevity. In step 201, for example, IP _ ALL _ HISTORY is not empty.
As an embodiment, in this embodiment, the first-class internet of things intelligent terminal device information is recorded to the first-time device data list dictionary (IP _ ALL _ NOW _ 1). On this premise, based on the description about the historical probe records stored in the IP _ ALL _ HISTORY, optionally, in this step 202, it may be determined first whether the IP _ ALL _ NOW _1 includes ALL pieces of information of the internet of things intelligent terminal device in the IP _ ALL _ HISTORY, and if not, it is determined that the first type of information of the internet of things intelligent terminal device does not include at least one piece of information of the internet of things intelligent terminal device in the third type of information of the internet of things intelligent terminal device. And once it is determined that the first type of internet-of-things intelligent terminal device information does not include at least one piece of internet-of-things intelligent terminal device information in the third type of internet-of-things intelligent terminal device information, it is indicated that some internet-of-things intelligent terminal devices in the internet of things may not be detected and found at this time, and in order to improve the accuracy of the detection of the internet-of-things intelligent terminal devices, a second detection stage needs to be executed in the detection period as described in step 202.
Thus, the flow shown in fig. 2 is completed.
How to determine to execute the second detection stage in the detection period according to the obtained information of the first type of internet of things intelligent terminal device is realized through the process shown in fig. 2.
As an embodiment, corresponding to the process shown in fig. 2, in step 103, the initiating the second detection phase in the detection period to detect the internet of things intelligent terminal device that is not detected in the first detection phase may include:
generating and sending a detection packet corresponding to the information of the intelligent terminal equipment of the internet of things in the detection period aiming at the information of each piece of intelligent terminal equipment of the internet of things which exists in the information of the intelligent terminal equipment of the third type of the internet of things but does not exist in the information of the intelligent terminal equipment of the first type of the internet of things; and the target IP address carried by the generated detection packet is the IP address contained in the information of the intelligent terminal equipment of the Internet of things. Still taking the case that the first-class internet-of-things intelligent terminal device information is recorded in IP _ ALL _ NOW _1 and the historical detection record is stored in IP _ ALL _ HISTORY as an example, the target IP address of the detection packet, such as the detection packet, corresponding to the internet-of-things intelligent terminal device information can be generated as the IP address included in the internet-of-things intelligent terminal device information for each piece of internet-of-things intelligent terminal device information which exists in IP _ ALL _ HISTORY but does not exist in IP _ ALL _ NOW _ 1. Finally, the intelligent terminal device of the internet of things which is not detected in the first detection stage is detected by initiating the second detection stage in the detection period.
It should be noted that, in this embodiment, when it is determined that the second probing phase does not need to be executed in the probing period according to the obtained first type of internet-of-things intelligent terminal device information, for example, when the IP _ ALL _ stop is empty, it is determined that the second probing phase is not executed in the probing period, and for example, when IP _ ALL _ NOW _1 includes ALL the internet-of-things intelligent terminal device information in IP _ ALL _ stop, it is determined that the second probing phase is not executed in the probing period, and the like, the following steps may be further performed: updating the historical detection record into the first type of Internet of things intelligent terminal equipment information; before the detection period is finished, whether the current condition for updating the historical detection record is met or not is checked, if not, the historical detection record is kept unchanged, and if yes, the historical detection record is emptied. Here, the condition of checking whether the update of the historical probe record is currently satisfied includes, but is not limited to: checking whether the current time is the set update time of the historical probe record, checking whether the update frequency of the historical probe record reaches the set update frequency threshold, and the like.
Taking an example of checking whether the update frequency of the historical probe record reaches the set update frequency threshold, based on the above-mentioned first-class internet-of-things intelligent terminal device information record to IP _ ALL _ NOW _1, and the historical probe record stores the description of IP _ ALL _ store, in this embodiment, IP _ ALL _ store is first updated to IP _ ALL _ NOW _1, and then before the above-mentioned probe period is ended, whether the update frequency of the current IP _ ALL _ store has reached the set update frequency threshold is checked, if not, IP _ ALL _ store is maintained unchanged (still is the above-mentioned updated IP _ ALL _ NOW _ 1), and if yes, IP _ ALL _ store is emptied. Here, when it is checked that the update frequency of the current IP _ ALL _ store has reached the set update frequency threshold, the recorded update frequency of IP _ ALL _ store is cleared, so that IP _ ALL _ store can be updated in time in each subsequent probing cycle. And when checking that the updating times of the current IP _ ALL _ HISTORY do not reach the set updating times threshold, increasing a set value such as 1 on the basis of the recorded updating times of the IP _ ALL _ HISTORY.
It should be further noted that, in this embodiment, when it is determined that the second detection phase does not need to be executed in the detection period according to the obtained first-type internet-of-things intelligent terminal device information, at this time, the detection discovery result of the detection period may be determined as the first-type internet-of-things intelligent terminal device information recorded in the IP _ ALL _ NOW _ 1.
In addition, as an embodiment, in the embodiment, after the probe device obtains the second type of internet-of-things intelligent terminal device information, the second type of internet-of-things intelligent terminal device information is recorded in a second secondary device data list dictionary (denoted as IP _ ALL _ NOW _ 2). Based on this, as described in step 104, the present embodiment finally outputs the union of IP _ ALL _ NOW _1 and IP _ ALL _ NOW _2 as the probing discovery result of the probing period, and updates IP _ ALL _ high to the union of IP _ ALL _ NOW _1 and IP _ ALL _ NOW _ 2.
