Fig. 3 illustrates a specific implementation flow of a method for judging an operation state of a proxy component of a data receiving component according to an embodiment of the present application, where, as shown in fig. 3, the proxy component of the data receiving component is taken as a first proxy component, the proxy component of the data receiving component is taken as a second proxy component, and a response rule includes that a field value of a first preset field is equal to a first standard value, where the method specifically includes:
S301, the first proxy component periodically sends a query packet to the second proxy component.
In this embodiment, the periods are divided according to a preset rule, for example, one period is divided every 5 seconds. Specifically, a query packet is sent to the second proxy component at the sending time indicated by each period, where the query packet is used to request the running state of the proxy component of the data receiving component, optionally, the query packet includes a response rule for generating a response packet by the proxy component of the data receiving component, that is, the query packet includes a field value of a first preset field in the generated response packet for indicating that the proxy component of the data receiving component is normal if the running state is normal, where the first standard value is a preset value indicating that the running state is normal.
S302, the second agent component responds to the received query packet to judge whether the running state of the second agent component is normal.
In this embodiment, the operation state includes a forwarding state, where the forwarding state indicates that the communication link of the second proxy component and the data receiving component is normal. The method for judging whether the forwarding state of the second proxy component is normal by the second proxy component includes various methods, for example, sending preset test information to the data receiving component, and if feedback information for responding to the test information, which is fed back by the data receiving component, is received within a second preset time, determining that the operation state of the second proxy component is normal.
S303, the second proxy component generates a response packet based on the running state and the response rule, and sends the response packet to the first proxy component.
In this embodiment, the second proxy component only generates a response packet with a field value of the first preset field equal to the first standard value when the query packet is successfully received and parsed and the forwarding state is normal.
It should be noted that, in the case that the operation state of the second proxy component is abnormal, the field value of the first preset field in the generated response packet is not equal to the first standard value, or in the case that the operation state of the second proxy component is abnormal, the operation of generating the response packet is not executed, that is, when the operation state of the second proxy component is abnormal, the response packet is not sent.
S304, the first proxy component receives the response packet within a first preset time period after sending the query packet, and if the field value of a first preset field in the response packet is not equal to a first standard value, marks the state of the corresponding period as abnormal.
In this embodiment, the first standard value is a preset value indicating that the running state is normal, for example, the first preset field is a status code, and the first standard value is 200, and if the status code in the response packet is not equal to 200, the status flag of the corresponding cycle is marked as abnormal.
S305, the first proxy component does not receive the response packet within a first preset time period after sending the query packet, and marks the state of the corresponding period as abnormal.
In this embodiment, the first proxy component polls all proxy components communicatively connected to the first proxy component according to a period, and executes the steps S301 to S305 for each polled proxy component, so as to obtain a status identifier of each period of each proxy component, and correspondingly stores the status identifier in a preset database.
S306, the first proxy component responds to the received original data packet and the identification of the data receiving component to acquire the state identification of the history period.
In this embodiment, the original data packet is sent by the data sending component, and the history period includes a period in a preset period of time before the current time, for example, the status identifiers of all periods in 24 hours are obtained. It should be noted that, the first proxy component obtains the status identifier around the history from the database.
S307, when the state identification of the history period meets the abnormal condition, the first proxy component determines that the running state of the second proxy component is abnormal.
In this embodiment, the abnormal conditions include: the state of the last consecutive n cycles is identified as abnormal, or the number of cycles for which the state is identified as abnormal is greater than a preset number threshold, where n is a preset number. Taking n=3 as an example and the number threshold=10 as an example, when the state identifications of 3 periods closest and consecutive to the current time in the history period are all abnormal, determining that the running state of the second agent component is abnormal. Alternatively, if the number of cycles in the history period for which the status is identified as abnormal is greater than 10, then the operational status of the second agent component is determined to be abnormal.
It should be noted that, the abnormal condition may be configured according to the historical operation log and the preset importance level of the original data packet. For example, if the importance level of the original data packet is high, n is preset to a small value or the number threshold is set to a small value for more stable transmission of the original data packet.
And S308, when the state identification of the history period meets the abnormal condition, the first proxy component sends a query packet to the proxy component of the data receiving component.
S309, the first proxy component does not receive the response packet or the field value of the first preset field in the response packet is not equal to the first standard value within the first preset time period after the first proxy component sends the query packet, and it is determined that the second proxy component operates abnormally.
S310, the first proxy component determines that the running state of the second proxy component is normal when the field value of a first preset field in the received response packet is equal to a first standard value within a first preset time period after the query packet is sent.
According to the method for acquiring the running state of the second proxy component, the running state of the proxy component of the data receiving component is periodically queried and marked, the state identification of the proxy component of the data receiving component is acquired after the identification of the original data packet and the data receiving component is received, and when the running state of the proxy component of the data receiving component at the current time is judged to be abnormal through the state identification and the abnormal condition, the running state abnormality of the proxy component of the data receiving component is determined without waiting for the instant response of the proxy component of the data receiving component, so that the speed of data transmission is improved. Further, according to the operation state of the proxy component of the data receiving component in the history period, the operation state of the proxy component of the data receiving component in the current time can be accurately judged.
Further, when the running state of the proxy component of the data receiving component at the current time cannot be judged to be abnormal through the state identification and the abnormal condition, the query packet is sent immediately to determine whether the running state of the proxy component of the data receiving component is normal or not, so that the judgment accuracy of the running state can be further improved.
It should be noted that, the above embodiment is only an optional specific implementation manner of the data transmission method provided by the embodiment, and the present application further includes other specific implementation manners.
For example, the method further includes that the field value of the first preset field in the response packet received by the first proxy component within the first preset time period after the query packet is sent is equal to the first standard value, and the state of the period corresponding to the mark is identified as normal, and in S304, whether the running state of the second proxy component is normal may be further determined according to the rule and the feature that the state of the history period is identified as normal, which is specifically referred to in the prior art, and this embodiment is not repeated. As another example, fig. 3 illustrates only one alternative reply rule, where the reply rule in the query packet includes multiple types, for example, the reply rule includes a rule code, where the rule code is used to indicate one of preset rules, and a correspondence between the preset rule and the rule code is stored in advance. That is, the answer rule is a dynamic rule.
For another example, the method further includes the step of determining whether the second agent component is normal according to the response condition, specifically including:
1. after the first proxy component sends the proxy data packet to the second proxy component, the response packet is received.
In this embodiment, the response packet is generated by the second proxy component in response to receiving the proxy data packet. The specific method for generating the response packet is referred to in the prior art, wherein the response packet is used for feeding back whether the proxy component of the data receiving component successfully forwards the original data packet to the data receiving component.
2. Judging whether the field value of the second preset field in the response packet is equal to a second standard value.
In this embodiment, the second standard value is a preset value indicating successful forwarding.
3. If not, the first proxy component sends the original data packet to the data receiving component.
Therefore, after the proxy data packet is sent, whether the operation state of the proxy component of the data receiving component is normal or not can be judged through the received response packet, so that the passive detection of the operation state is realized, and the stability of data transmission and the instantaneity of the judgment result of the operation state can be further improved.
