The application shows a method for determining transmission delay information of a DPI device, which is applied to a network service system, wherein the network service system generally comprises user equipment, the DPI device and network equipment, and the network service system is completed by matching three terminals. As a non-exemplary scenario, fig. 1 shows a typical scenario of the present application, where transmission data of one or more user equipments is sent to a network device through a DPI device, and the network device forwards the transmission data to the user equipment through the DPI device, and the like, where the DPI device is mainly configured to perform filtering control on the transmission data according to a predefined policy, and perform functions of fine traffic identification, traffic flow direction analysis, traffic flow proportion statistics, traffic proportion shaping, application layer denial of service attack, filtering viruses or trojans, and abusing control of P2P on the links where the DPI device is located. In other words, the DPI device collects and identifies traffic on the link and distributes traffic or analysis statistics to the network devices that meet the needs of other systems. The data processing of the DPI device may cause transmission delay to data transmission, if the corresponding transmission delay information is within an allowable delay interval, the data processing of the current DPI device is relatively normal, and if the transmission delay information is outside the allowable delay interval, the data processing function of the current DPI device may be abnormal. The method and the device determine whether the data transmission process is abnormal or not by determining the transmission delay information of the DPI equipment.
In this embodiment, the network device may be an independent server, or may be a server network or a server cluster composed of servers, for example, the computer device described in this embodiment includes, but is not limited to, a computer, a network host, a single network server, a plurality of network server sets, or a cloud server composed of a plurality of servers. Among them, the Cloud server is constituted by a large number of computers or web servers based on Cloud Computing (Cloud Computing).
Those skilled in the art can understand that the application environment shown in fig. 1 is only one application scenario of the present application, and does not constitute a limitation on the application scenario of the present application, and as a person skilled in the art knows that as a network service scenario evolves and a new network service scenario appears, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
Referring to the system topology shown in fig. 1, fig. 2 shows a method for determining transmission delay information of a DPI device according to an aspect of the present application, which is applied to a network device located in a network service system, where the network service system further includes a user equipment and a DPI device, and the user equipment communicates with the network device via the DPI device, and the method includes step S101, step S102, step S103, and step S104. In step S101, a network device acquires transmission data information sent by the user equipment and forwarded by the DPI device and an initial transmission time corresponding to the transmission data information; in step S102, the network device adjusts forwarding delay information of the transmission data information in the network device; in step S103, the network device returns the transmission data information to the user equipment through the DPI device, and acquires a transmission end time of the DPI device; in step S104, the network device determines transmission delay information of the DPI device according to the initial transmission time, the forwarding delay information, and the end transmission time.
Specifically, in step S101, the network device acquires the transmission data information transmitted by the user equipment and forwarded by the DPI device, and the initial transmission time corresponding to the transmission data information. For example, an application (such as a third-party application, an applet, or a plug-in) corresponding to a network device is installed in a user equipment, the user equipment sends corresponding transmission data to the network device through the application, and the transmission data is sent to a DPI device for data processing, and is sent to the network device after being detected by the DPI device. When the user equipment sends the transmission data, the user equipment also sends the initial transmission time of the transmission data to the network equipment at the same time, in some cases, the initial transmission time comprises the time of starting transmission when the first byte of the transmission data is read at the user equipment side, and in other cases, the initial transmission time comprises the initial transmission time when the last byte of the transmission data is read at the user equipment side and is ready to be sent. For convenience of calculation, the following embodiments are described by taking the time when the last byte of the transmission data is read and ready to be sent as the corresponding start transmission time as an example, and it should be understood by those skilled in the art that the case where the time when the first byte of the transmission data is read at the ue side starts transmission is taken as the corresponding start transmission time is also applicable to the following embodiments, and shall be included in the scope of the present application.
In step S102, the network device adjusts forwarding delay information of the transmission data information at the network device. For example, the forwarding delay information is used to indicate the forwarding duration of the transmission data information in the network device, and the like, for example, if the starting time at which the network device starts to receive the transmission data information is counted until the corresponding network device finishes forwarding the transmission data information, the forwarding duration obtained by the counting is the corresponding forwarding delay information. The forwarding delay information may be obtained by the network device side according to a random number, or obtained by setting operation of a manager. In general, the forwarding delay information is smaller than a corresponding forwarding time threshold, and the like, where the forwarding time threshold is used to indicate a time corresponding to the abnormal data transmission of the user equipment, and if the user equipment does not receive the corresponding forwarded data information and the like within the forwarding time threshold after sending the corresponding data transmission information, the user equipment determines that the current data transmission process is abnormal and the like.
In step S103, the network device returns the transmission data information to the user equipment via the DPI device, and acquires the transmission end time of the DPI device. For example, the network device returns the corresponding transmission data information to the user device via the DPI device, and the user device records an end transmission time of the transmission data, corresponding to the start transmission time, in some cases, the end transmission time includes a time corresponding to the transmission data information being completely received by the user device, and in other cases, the end transmission time includes a time corresponding to the transmission data information being started to be received by the user device. For convenience of calculation, the following embodiments are described by taking the time corresponding to the start of receiving the transmission data information by the ue as the corresponding transmission ending time, and those skilled in the art should understand that the case of taking the time corresponding to the complete receiving of the transmission data information by the ue as the corresponding transmission ending time is also applicable to the following embodiments and shall be included in the scope of the present application.
In step S104, the network device determines transmission delay information of the DPI device according to the initial transmission time, the forwarding delay information, and the end transmission time. For example, after the network device acquires the corresponding initial transmission time, the forwarding delay information and the corresponding end transmission time, the transmission delay information of the DPI device may be calculated according to the corresponding information, where, considering that the duration of data in the transmission process in the link is smaller than the processing duration of the DPI device, we ignore the transmission duration in the link process, and use the time difference calculated in the whole process except the network device forwarding delay as the transmission delay information of the DPI device. For example, assuming that the starting transmission time is T1, the ending transmission time is T2, and the forwarding delay information is T1, the corresponding transmission delay information is T2 ═ T2-T1) -T1, that is, the transmission delay information of the DPI device is obtained by subtracting the forwarding delay information at the network device end from the whole duration in the transmission process.
In some embodiments, in step S102, the network device records a receiving transmission time corresponding to receiving the transmission data information, and determines a forwarding transmission time corresponding to the transmission data information according to the receiving transmission time and corresponding forwarding delay information; wherein, in step S103, the method includes: and returning the transmission data information to the user equipment through the DPI equipment at the forwarding transmission moment. For example, the receiving transmission time includes a time when the network device starts receiving the transmission data, and the forwarding transmission time includes a time when the network device finishes forwarding the transmission data, in some cases, the data size of the transmission data is small, the corresponding transmission rate is fast, the time length of reading or forwarding the transmission data information is far shorter than the forwarding delay information, the time consumed by reading the data when the transmission data information is received or forwarded can be ignored, and the corresponding forwarding transmission time can be directly calculated. If the receiving transmission time is assumed to be T3, the corresponding forwarding transmission time T4 is T3+ T1, in other words, the forwarding transmission time is added to the corresponding forwarding delay information to obtain the corresponding forwarding transmission time. And after the network device calculates the corresponding forwarding transmission time, controlling the stay time of the transmission data information in the network device, and returning the transmission data information to the user equipment through the DPI device when the time reaches the corresponding forwarding transmission time T4. The method and the device can flexibly control the forwarding delay information of the network equipment to the transmission data information so as to more accurately determine the delay information of each link, and are favorable for the stability, the efficiency and the like of the operation of a network service system.
In some embodiments, the data volume of the data is large, the data frame is long, and the corresponding data transmission rate is slow, so that the corresponding data transmission duration may affect the calculation of the time delay, and we need to calculate more accurate time delay information after excluding the data transmission duration. In step S102, the network device obtains a data transmission duration of the transmission data information; determining data staying time corresponding to the transmission data information according to the data transmission time and the forwarding time delay information; and determining corresponding forwarding transmission time according to the receiving transmission time, the data transmission time and the data staying time. For example, when the data transmission duration of the transmission data is not intentionally ignored or the like with respect to the forwarding delay information, for example, the data transmission duration of the transmission data is greater than or equal to a ignoring threshold (for example, one-twentieth or the like) of the forwarding delay information, the network device acquires the data transmission duration of the transmission data information, for example, the network device may receive the data transmission duration of the transmission data information sent by the corresponding user equipment or DPI device, and for example, the network device may calculate the data transmission duration of the transmission data information according to the transmission rate and the data frame length of the transmission data information, for example, in some embodiments, the acquiring the data transmission duration of the transmission data information includes: and acquiring the length of a data frame of the transmission data information and a corresponding transmission rate, and determining the data transmission duration of the transmission data information according to the length of the data frame and the transmission rate. For example, the network device may obtain the data transmission duration of the transmission data information by dividing the length of the data frame by the corresponding transmission rate, and after obtaining the data transmission duration, the network device determines the corresponding data retention duration by receiving the transmission time, the forwarding delay information, and the like, and determines the corresponding forwarding transmission time based on the data retention duration, and the like. Here, the forwarding transmission time includes a time when the first byte of the transmission data information starts to be received by the network device, the forwarding transmission time includes a time when the first byte of the transmission data information is forwarded by the network device, and assuming that the corresponding data transmission duration is t0, the data staying duration t3 of the corresponding transmission data information at the network device is t1-2 t 0; subsequently, the corresponding forwarding transmission time T4-T3 + T0+ T3, and the end forwarding time T5-T4 + T0-T3 + T1 of the network device ending forwarding data can be determined according to the forwarding transmission time and the data transmission duration.
In some embodiments, more accurate transmission delay information may be determined according to the data transmission duration, for example, in step S104, the network device determines the transmission delay information of the DPI device according to the starting transmission time, the forwarding delay information, the ending transmission time, and the data transmission duration. For example, a plurality of data transmission durations in the transmission flow are removed, and transmission delay information of the DPI device can be determined more accurately, if the transmission data information passes through the DPI device twice in the transmission flow, time corresponding to four data transmission durations needs to be subtracted on the basis, in other words, transmission delay information T2' ═ T2-T1) -T1-4 × T0 of the DPI device is used to characterize the duration of processing the transmission data information by the DPI device. Certainly, in some cases, if an abnormal situation of data in the transmission process of each link needs to be eliminated, delay information of each link needs to be calculated, except for the transmission delay of the DPI device end, delay information corresponding to a user device, a DPI device, a network device, and a transmission link between the DPI device and the network device, and the like, and the transmission delay information in the link is collectively referred to as other delay information. As in some embodiments, the method further includes step S105 (not shown), in step S105, the network device acquires a data receiving time and a data sending time corresponding to the DPI device; in step S104, determining transmission delay information and other delay information of the DPI device according to the initial transmission time, the forwarding delay information, the end transmission time, the data transmission duration, the data receiving time, and the data sending time, where the other delay information includes delay information of the transmission data in other transmission processes except the DPI device and the network device. For example, the DPI device records a corresponding data receiving time and a corresponding data sending time, where the corresponding data receiving time includes a time when the DPI device starts to receive transmission data information, for example, a time when the DPI device starts to receive a first byte of the transmission data information, and times when the DPI device starts to receive data from the user equipment end or the network device end are T6, respectively; the data sending time includes a time corresponding to the DPI device that finishes sending the transmission data information, for example, the DPI device finishes sending the last byte of the transmission data information, and the time corresponding to sending the data to the network device or the user equipment is T7 respectively. Here, the reception data time and the transmission data time are times when data passes through the DPI on the same side, and the like. The transmission delay information T2 ═ T7-T6-2 × T0 corresponding to the DPI device, and the other delay information T4 ═ T2-T1) -T1-2 × T2 corresponding to the DPI device. The method and the device can more accurately determine the time delay information in each process in the information transmission process, thereby achieving the accurate control of the information transmission process in the network service system, and being capable of quickly positioning and processing the data transmission abnormity.
In some embodiments, the method further comprises step S106 (not shown). In step S106, the network device verifies the reliability of the delay exception handling of the user equipment based on the forwarding delay information. For example, the user equipment sets a forwarding duration threshold corresponding to data transmission abnormality, and the like, and if the total forwarding duration of the transmitted data information exceeds the forwarding duration threshold T0, that is, T2-T1 > T0, the user equipment determines that the transmission process of the currently transmitted data information is abnormal, and packet loss or data interception may occur, and the like, the user equipment sends the transmitted data information to the network equipment again or sends an abnormality prompt message to the network equipment to prompt that the network equipment has abnormality in the data transmission at this time. The normal interval of the forwarding delay information of the network equipment end can be calculated through the forwarding time length threshold and the transmission delay information, for example, the normal interval is less than or equal to T0-T2, and if the forwarding delay information of the network equipment is set to be greater than or equal to T0-T2, whether the delay abnormity processing function of the user equipment is reliable can be verified. If the forwarding delay information is set to T0, if the network device receives the transmission data information retransmitted by the user equipment or receives the exception prompt information transmitted by the user equipment within a certain time, the network device determines that the delay exception handling function of the user equipment is normal; if the network device does not receive the transmission data information retransmitted by the user device within a certain period of time and receives the abnormal prompt information transmitted by the user device, the network device determines that the time delay abnormal processing function of the user device is abnormal, transmits the prompt information corresponding to the time delay abnormal processing function abnormality to the user device, and prompts a user corresponding to the user device to reduce criminal overhaul of the corresponding function of the user device, and the like.
