[0043] The application will be further described in detail below with reference to the drawings and the application.

[0044] In order to solve the problem that it is difficult to effectively monitor the synchronization state and service traffic of the time-triggered Ethernet device in actual networking test, the embodiment of the present application provides a traffic monitoring test method in TTE network test, which is applied to a traffic monitoring test system, as shown in Figure 1 , Figure 1 is a structural schematic diagram of the traffic monitoring test system provided by the embodiment of the present application, and the traffic monitoring test system comprises a data interface module, a frame information shunting module, a test configuration module, a local time recording module, a service frame monitoring module, a synchronization frame monitoring module, a synchronization frame transparent transmission control module, a forwarding management module, an exception storage module, an exception reporting module and a PCIE interface.

[0045] Next, the traffic monitoring test method in TTE network test provided by the embodiment of the present application will be described in detail in combination with the traffic monitoring test system. As shown in Figure 2 , Figure 2 is a flow schematic diagram of the traffic monitoring test method in TTE network test provided by the embodiment of the present application, and the traffic monitoring test method in TTE network test specifically comprises the following steps:

[0046] In step S201, the test configuration information of the TTE network is read.

[0047] Firstly, the test configuration module in the traffic monitoring test system configures the test configuration information and performs port division of the monitoring flow. The test configuration information of the TTE network comprises service monitoring configuration information and synchronization monitoring configuration information of the traffic monitoring test system, as shown in Figure 3 , Figure 3 is a format schematic diagram of the service monitoring configuration information of the traffic monitoring test system provided by the embodiment of the present application, and the service monitoring configuration information of the traffic monitoring test system comprises a lower limit and an upper limit of service traffic, a service MAC (Media Access Control) address and a service frame type; the service MAC address further comprises a service source MAC address and a service destination MAC address. As shown in Figure 4 , Figure 4 is a format schematic diagram of the synchronization monitoring configuration information of the traffic monitoring test system provided by the embodiment of the present application, and the synchronization monitoring configuration information of the traffic monitoring test system comprises a synchronization MAC address, a basic period, a matrix period and a synchronization parameter; the synchronization MAC address further comprises a synchronization source MAC address and a synchronization destination MAC address. It should be noted that, during the configuration, the synchronization frame test only needs to be configured once, the service frame needs to be configured multiple times according to different frame types, and when the parameters need to be refreshed, the parameters can be refreshed by reconfiguration.

[0048] In the embodiment of the application, the initial configuration information is sent by the upper computer, and the initial configuration information is received from the upper computer through the PCIE interface and transmitted to the service frame monitoring module and the synchronization frame monitoring module.

[0049] Further, the test configuration information of the TTE network can specifically include a traffic lower limit and a traffic upper limit of the service frame, a source MAC address of the service frame, a destination MAC address of the service frame, and a frame type of the service; a source MAC address and a destination MAC address of the synchronization frame, a basic period, a matrix period, and a synchronization parameter, the synchronization parameter including a basic period number range, a member vector value, a synchronization priority, a synchronization domain, a synchronization frame type, a transparent clock value, and a reserved field value; and port division including determination of an input port number and an output port number of a data stream.

[0050] Next, network topology connection is performed, the traffic monitoring test system is connected to the original TTE network, a start test instruction is sent, the local time counter starts timing, and the test configuration information is read.

[0051] The data interface module in the traffic monitoring test system can be used to read the test configuration information of the TTE network, the data interface module is used to convert the physical signal of the network into data in the TTE standard format, and the TTE network data frame is obtained. The data interface module can include a PHY (Physical, physical layer) and a MAC general IP (Intellectual Property Core) core, wherein the IP core refers to a pre-designed, verified and reusable functional module.

[0052] In the embodiment of the application, the local time counter, that is, the local time recording module, records the time point of occurrence of a link abnormal event according to a test duration register configuration selection timing test mode or a long-term monitoring mode; when the system issues a test configuration instruction, the configuration register is set to 1, and at this time, the local time counter starts working. This signal flag is equivalent to the start switch of the counter. The two working modes include the timing test mode or the long-term monitoring mode, when the test duration register is configured at the same time, the specific test time can be realized, if the test duration register is not configured, the long-term monitoring mode is used by default, at this time, each time the link has an abnormal situation, the abnormal information fault code and the time point of occurrence are reported; at the same time, the local time can be used for subsequent recovery of the original data stream in the forwarding management module and forwarding output.

[0053] In step S202, the data frame sent by the TTE network is received, and the data frame is shunted into the service frame and the synchronization frame.

[0054] In the embodiment of the present application, the frame information shunting module in the traffic monitoring test system can be used to analyze the frame content of the TTE network data frame, including the frame type field, MAC address, basic cycle number of the synchronization frame, member vector number, synchronization priority, synchronization domain, synchronization frame type and transparent clock, and according to the frame type field, the frame information is shunted to the service frame monitoring module and the synchronization frame monitoring module.

[0055] In an implementation manner, the service frame includes a TT (Time-Triggered) frame, a RC (Rate-Constrained) frame and a BE (Best-Effort) frame, and the TTE network synchronization frame type includes a PCF frame.

[0056] In step S203, based on the test configuration information, the traffic bandwidth of the service frame is counted, and when the traffic of the service frame is abnormal, the first abnormal event and the corresponding abnormal time point are recorded.

[0057] In the embodiment of the present application, the service frame monitoring module in the traffic monitoring test system can be used to count the traffic bandwidth of the service frame of the input port, count according to different service frame types, and when the MAC address of the service frame does not match the configuration or the bandwidth is abnormal, the first abnormal event is generated. Wherein, the traffic bandwidth = frame length of the data frame * (number of received data frames / unit time).

[0058] In the embodiment of the present application, for the three types of service frames, frame field checking and traffic bandwidth counting are performed, and when the traffic is abnormal, the bandwidth abnormal information and the current abnormal time point are recorded, as follows:

[0059] According to the frame information of the service frame received by the input port, the port traffic bandwidth is counted and the frame field is checked, and at this time, the receiving time point of the input service stream is recorded, which is used for subsequent recovery of the output data stream.

[0060] In an implementation manner, the bandwidth range of the service frame depends on the service scheduling of the end system connected by the input port, and the bandwidth characteristics of different service types are different, which are mainly divided into the following three types.

[0061] In the embodiment of the present application, when the service frame is a TT frame, based on the test configuration information, the traffic bandwidth of the service frame is counted, and when the traffic of the service frame is abnormal, the first abnormal event and the corresponding abnormal time point are recorded, including:

[0062] The traffic bandwidth of the TT frame is counted, when it is determined that the bandwidth fluctuation of the TT frame is greater than a preset threshold, the service frame traffic bandwidth abnormality and the corresponding abnormal time point are recorded; the preset threshold is determined according to the test configuration information.

[0063] Specifically, in the TTE network, the TT service is a static planning deterministic time triggered service, each TT frame has a fixed dispatch time point and a flow ID (Identifier, identifier), and is sent in a matrix cycle, so the TT bandwidth information of the link can be calculated according to all TT frames and frame lengths in a matrix cycle. When the link is stable, the bandwidth of the TT frame is relatively stable, and when the TT service bandwidth on the link fluctuates greatly, it indicates that there is a frame loss phenomenon in the TT frame on the link.

[0064] The specific preset threshold value can be set by the technician based on the test configuration information according to experience, which is not limited here.

[0065] In the embodiment of the application, when the service frame is an RC frame, based on the test configuration information, the traffic bandwidth of the service frame is counted, and when the traffic of the service frame is abnormal, the first abnormal event and the corresponding abnormal time point are recorded, including:

[0066] The traffic bandwidth of the RC frame is counted, and when the bandwidth upper limit of the RC frame exceeds the BAG limit, the service frame flow ID abnormality and the corresponding abnormal time point are recorded; the BAG limit is determined according to the test configuration information.

[0067] Specifically, in the TTE network, RC service divides different BAG (Bandwidth Allocation Gap, bandwidth allocation gap) according to flow ID, and performs rate limiting, so the upper limit of the RC frame bandwidth is the traffic bandwidth calculated according to the maximum frame length sent in unit time according to the BAG. Therefore, when the link is stable, the bandwidth of the RC frame is relatively stable, and there is an upper limit, when the RC on the link exceeds the upper limit, it indicates that the RC frame on the link exceeds the BAG limit, and there is an abnormality.

[0068] The specific BAG limit value can be set by the technician based on the test configuration information according to experience, which is not limited here.

[0069] In the embodiment of the application, when the service frame is a BE frame, based on the test configuration information, the traffic bandwidth of the service frame is counted, and when the traffic of the service frame is abnormal, the first abnormal event and the corresponding abnormal time point are recorded, including:

[0070] The traffic bandwidth of the BE frame is counted, and when the MAC address of the BE frame is inconsistent with the test configuration information, the service frame MAC address abnormality and the corresponding abnormal time point are recorded.

[0071] Specifically, in the TTE network, the BE service does not have the characteristics of the flow ID and static planning, and the MAC address monitored on the link should be consistent with the test configuration information. Since the link bandwidth allocation of the BE service has randomness, but the transmission rate will not exceed the upper limit of the link transmission rate. Therefore, when the source MAC address or the destination MAC address of the BE frame abnormally changes, the link is abnormal.

[0072] Based on the above analysis, the first abnormal event in the embodiment of the application can include service frame traffic bandwidth abnormality, service frame flow ID abnormality, and service frame MAC address abnormality.

[0073] In the embodiment of the application, the time recording module in the traffic monitoring test system can be used to record the local receiving time of the TTE network data frame, to output the flow recovery and abnormality record. The time recording module records the local receiving time stamp of the received TTE network data frame by maintaining a local clock, and outputs the input flow to the output port after a fixed time delay. When an abnormality occurs, the local clock is read as an abnormal time point, and the abnormal event point includes the abnormal event start time and the abnormal event end time.

[0074] In step S204, based on the test configuration information, the synchronization frame is transparently transmitted, and when the content of the synchronization frame is abnormal, the second abnormal event and the corresponding abnormal time point are recorded.

[0075] In the embodiment of the application, the synchronization frame monitoring module in the traffic monitoring test system is used to determine whether the synchronization frame of the input port is consistent with the AS6802 protocol, to perform protocol legality checking, and to count and determine the receiving time. When the synchronization frame is inconsistent with the protocol or the arrival time deviates too much, an abnormal event is generated.

[0076] In the embodiment of the application, the service frame includes a PCF frame. In the TTE network, the PCF service frame length is fixed, and in the stable synchronization state, the scheduling time point is relatively fixed, so the bandwidth is relatively fixed. Therefore, whether there is a behavior inconsistent with the AS6802 protocol is mainly monitored.

[0077] Further, the second abnormal event includes synchronization frame arrival time abnormality, synchronization frame content abnormality, and / or synchronization frame protocol inconsistency abnormality. Taking the synchronization frame arrival time abnormality and the synchronization frame protocol inconsistency abnormality as examples, the traffic monitoring test method in the TTE network test provided by the embodiment of the application is further described.

[0078] Specifically, the PCF frame is further divided into three types of frames, namely, a CS cold start frame, a CA cold start response frame and an IN synchronization frame. In a state of stable synchronization of the network, a synchronization frame is scheduled to be sent in each basic period, and when a synchronization frame of a monitored link is not received for more than one basic period, it is considered that a missing fault occurs, and it is determined that a synchronization frame arrival time abnormality event occurs; at this time, the arrival time of a next received synchronization frame and the frame content are monitored, and when the basic period in which the synchronization frame is not received does not exceed the synchronization threshold of the stable synchronization state, it is considered that the device connected by the link is still in a synchronization state, and the subsequent received synchronization frame should be an IN frame; when the basic period in which the synchronization frame is not received exceeds the synchronization threshold of the stable synchronization state, it is considered that the device connected by the link should be in an unsynchronized state, and the subsequent received synchronization frame should be a CS frame; when the received synchronization frame is not the above case, it is determined that a synchronization frame protocol inconsistency abnormality occurs.

[0079] In the embodiment of the application, for the synchronization frame, transparent transmission is performed, and when an abnormality occurs, synchronization abnormality information fault codes and the current abnormality time point are recorded, and the specific process is as follows:

[0080] According to the frame information of the TTE network synchronization frame received by the input port, first, the synchronization state and the unsynchronized state are judged through the received frame content, when the received frame at this time is an IN frame interacted in the synchronization state, it is considered that the input port device is in a synchronization state, when the received frame at this time is a CS frame and a CA frame interacted in the synchronization state, it is considered that the input port device is in an unsynchronized state, the receiving time point is recorded, and the test device forwarding delay is corrected into the transparent clock parameter of the synchronization frame.

[0081] In the embodiment of the application, the synchronization frame transparent transmission control module in the traffic monitoring test system is used for modifying the transparent clock value of the synchronization frame, and adding the introduced forwarding delay to the transparent clock of the synchronization frame field, without affecting the original network synchronization effect.

[0082] In the embodiment of the application, the forwarding management module in the traffic monitoring test system is used for scheduling and arranging the forwarding of the synchronization frame and the service frame according to the flow characteristics distribution of the input port.

[0083] In step S205, the first abnormality event and / or the second abnormality event and the respective abnormality time points are reported to the upper computer.

[0084] In the embodiment of the application, the abnormality storage module in the traffic monitoring test system is used for storing the abnormality event and the fault code, and when the abnormality reporting module sends a reading signal, the abnormality event is sent to the abnormality reporting module.

[0085] The abnormality reporting module in the flow monitoring test system can have two working modes according to different test configurations, one is to report periodically according to preset configuration, and the other is to report immediately when an abnormal event occurs.

[0086] In an implementation mode, the first abnormal event and / or the second abnormal event and the respective abnormal time points are reported to an upper computer, including:

[0087] All the first abnormal events and / or the second abnormal events and the respective abnormal time points in a preset configuration reporting period are combined, and the combined result is reported to the upper computer.

[0088] In the embodiment of the application, the preset configuration reporting period can be set by a technician according to experience, which is not limited herein.

[0089] In the embodiment of the application, the PCIE interface in the flow monitoring test system is a data interface of the upper computer, and the test information configuration and the abnormal event reporting can be performed from the upper computer.

[0090] Referring to Figure 5 , Figure 5 is a format diagram of the abnormal event reported by the flow monitoring test system provided by the embodiment of the application, and the format of the abnormal event reported by the flow monitoring test system can include an abnormal type, a fault code, a fault occurrence start time and a fault occurrence end time. The abnormal type can include the first abnormal event and the second abnormal event; the fault code is a code for uniquely identifying a specific fault type, which can facilitate quick identification and problem handling; the fault occurrence start time and the fault occurrence end time can be obtained by recording the corresponding abnormal time points when the abnormal event occurs.

[0091] In the embodiment of the application, when a fault occurs, long-term continuous monitoring can be selected, and the abnormality can be reported periodically according to a preset reporting period, or the abnormality can be reported immediately when the abnormality occurs. When multiple abnormalities occur simultaneously, the abnormality conditions can be combined and uploaded, the abnormal type, the fault code, the start and end time of multiple abnormal conditions are recorded, the information of multiple abnormal types is in a bit mapping format, one bit in the reported abnormality corresponds to each specific fault, and a specific number of start and end time is allocated to each abnormality.

[0092] In the embodiment of the present application, the service frame and the synchronization frame specific to the TTE network are monitored in detail, the traffic bandwidth of the service frame is counted based on the test configuration information of the TTE network, and when the traffic of the service frame is abnormal, the first abnormal event and the corresponding abnormal time point are recorded; the synchronization frame is transparently transmitted based on the test configuration information, and when the content of the synchronization frame is abnormal, the second abnormal event and the corresponding abnormal time point are recorded. Through this traffic monitoring mechanism, the normal transmission of various service flows can be ensured, the synchronization function of the original network can be ensured, the abnormal monitoring of the specific link in the large-scale TTE network can be realized, the long-term test of the stability of the TTE network can be realized, and the efficiency of the TTE network test is improved.

[0093] The three service frames and one synchronization frame specific to the TTE network are monitored in detail. For the three service frames, the data flow bandwidth input to the test device can be dynamically calculated through the traffic bandwidth counting function, and when the traffic is abnormal, the abnormal fault code can be reported through the abnormal diagnosis function; for the synchronization frame, the transparent clock value of the synchronization frame can be corrected through the transparent transmission function, the original synchronization effect of the network is not affected, and whether the arrival time of the synchronization frame at this time is consistent with the expected value and whether the frame content is abnormal can be determined through the abnormal diagnosis function.

[0094] The traffic monitoring test method for TTE network test provided by the embodiment of the present application can monitor multiple TTE links at the same time, realize abnormal analysis and diagnosis, and report the abnormal situation of the link.

[0095] Based on the same inventive concept, the embodiment of the present application further provides a traffic monitoring test device for TTE network test, which is described with reference to Figure 6 , Figure 6 is a structural schematic diagram of a traffic monitoring test device for TTE network test provided by the embodiment of the present application, and the device comprises:
