Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of network communication, and in particular to a data processing method, system and device. BACKGROUND

[0002] A service intelligence gateway (SIG) is a device / system that uses service awareness (SA) technology to implement functions such as traffic analysis, bandwidth management, and network security protection. The SIG can work in cooperation with a versatile business platform (VBP). The SIG serves as the foreground, and the VBP serves as the background. The foreground can be used for traffic detection, policy implementation and application, and reporting of statistical data. The background can be used for device management, user management, traffic management, security management, and log management.

[0003] However, due to load sharing, policy routing, or node failure, and for other reasons, the transmission paths of uplink data streams and downlink data streams of the same service can be inconsistent. In this case, the SIG can only receive data streams in a single direction. The data features obtained by the SIG through detection of the data streams in the single direction can be inaccurate or even unable to be detected, which can result in poor traffic management by the VBP. SUMMARY

[0004] The present application provides a data processing method, system and device, which are used to solve the problem of poor traffic management due to inaccurate detection of data features of data streams in different directions of the same service.

[0005] To achieve the above object, the present application adopts the following technical solutions:

[0006] In a first aspect, a data processing method is provided. The method can be applied to a first device, or a functional module in the first device, such as a chip or a chip system. The method is described below with the first device as the execution subject. The data processing method can include: obtaining, by the first device, a first data feature of a first data stream and a second data feature of a second data stream. The first data stream is one of an uplink data stream or a downlink data stream of a first service, and the second data stream is the other of the uplink data stream or the downlink data stream of the first service. The transmission paths of the first data stream and the second data stream are different. The first device combines the first data feature and the second data feature to obtain a third data feature. The first device is a traffic detection device or a service management device.

[0007] Based on the scheme, in the scenario of asymmetric routing of the bidirectional data flow of the first service, the traffic detection device of the same foreground or the service management device of the same background can still obtain the data features of the data flow of two different directions of the first service. Based on this, the problem that the data features of the detected unidirectional data flow are inaccurate in the current asymmetric routing scenario can be overcome. In addition, the service management device of the background can perform traffic management according to the complete data features of the bidirectional data flow, so that the effect of traffic management can be improved.

Based on this, the problem that the data features of the detected unidirectional data flow are not accurate enough can be overcome.

[0069] Before the embodiments of the present application are introduced, some terms and related technologies involved in the embodiments of the present application are explained. It should be noted that the following explanations are provided to make the embodiments of the present application more easily understood, and should not be regarded as limiting the scope of protection claimed by the embodiments of the present application.

[0070] In the art, the SIG can be a proprietary device with SA capability, or can be implemented by multiple devices together.

[0071] As a possible implementation manner, the SIG can be implemented by a broadband remote access server (BRAS) and a SA board together. As another possible implementation manner, the SIG can be implemented by a service router (SR) and a SA board together. As still another possible implementation manner, the SIG can be implemented by a provider edge (PE) and a SA board together. As still another possible implementation manner, the SIG can be implemented by a deep packet inspection (DPI) device.

[0072] The SIG can work with the VBP, and the SIG is in the foreground and the VBP is in the background. The SIG can be deployed on a transmission path of a data flow and can be used to detect the data flow passing through the SIG. However, due to load sharing, policy routing, or node failure, and for many other reasons, there can be a routing asymmetry between the uplink data flow and the downlink data flow of the same service, that is, the transmission paths of the uplink data flow and the downlink data flow of the same service are different. In this case, the uplink data flow and the downlink data flow of the same service pass through different SIGs. Therefore, a single SIG only receives a unidirectional data flow (uplink data flow or downlink data flow) of the same service, which can cause the SIG to be unable to identify the data characteristics of the data flow or the identified data characteristics to be inaccurate, and further affect the effect of traffic management on the service.

[0073] For example, Figure 1 A schematic diagram of a scenario of routing asymmetry between the uplink data flow and the downlink data flow of the same service is shown, as shown in Figure 1 As shown, the user equipment 101 is connected with the user access equipment 102, the user access equipment 102 is connected with the router 103a and the router 103b respectively, the router 103a is connected with the SIG 104a, the router 103b is connected with the SIG 104b, the SIG 104a is connected with the router 105a, the SIG 104b is connected with the router 105b, the router 105a and the router 105b are both connected with the core router (CR) 106, and the CR 106 is connected with the network side. The user access equipment 102 can be an access gateway, an access switch, or an access router, and the like.

[0074] In Figure 1In the illustrated network scenario, the uplink data stream of the user equipment 101 can be transmitted to the network side in sequence through the user access device 102, the router 103a, the SIG 104a, the router 105a, and the CR 106, and the downlink data stream of the user equipment 101 can be transmitted to the user equipment 101 in sequence through the CR 106, the router 105b, the SIG 104b, the router 103b, and the user access device 102, and the routing of the uplink data stream and the downlink data stream of the user equipment 101 is asymmetric.

[0075] Optionally, continuing to refer to Figure 1 , the SIG 104a and the SIG 104b can be connected with the VBP 107 in the background, and the SIG 104a and the SIG 104b can report the related information of the data stream to the VBP 107. The VBP 107 can manage according to the related information of the data stream reported by the SIG 104a and the SIG 104b, for example, can issue the traffic policy corresponding to the data stream of the SIG 104a and the SIG 104b.

[0076] In Figure 1 the illustrated scenario, the SIG 104a only receives the uplink data stream of the user equipment 101, and the SIG 104b only receives the downlink data stream of the user equipment 101. In this case, the SIG 104a or the SIG 104b can not be able to identify the one-way data stream (i.e., the uplink data stream or the downlink data stream) of the user equipment 101, or the identification of the data characteristics of the one-way data stream is not accurate. Further, it will cause the VBP 107 to be unable to accurately manage the traffic of the user equipment 101.

[0077] In view of the above problems, the present application provides a data processing method, the traffic detection device in the foreground can combine the data characteristics of the uplink data stream and the data characteristics of the downlink data stream of the same service into complete data characteristics of the bidirectional data stream, and then send the complete data characteristics of the bidirectional data stream to the service management node in the background for processing. Alternatively, the management node in the background receives the data characteristics of the one-way data stream first, and then combines the data characteristics of the one-way data stream into complete data characteristics of the bidirectional data stream before processing. In summary, even in the scenario where the routing of the uplink data stream or the downlink data stream of the same service is asymmetric, the service management device in the background can still manage the traffic according to the complete data characteristics of the bidirectional data stream of the same service, and the management effect is better.

[0078] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, " / " represents an "or" relationship between the objects before and after the " / ", for example, A / B can represent A or B; in the present application, "and / or" is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent: A alone, A and B together, and B alone, where A and B can be singular or plural. In the description of the present application, unless otherwise specified, "multiple" means two or more than two. "At least one of the following" or similar expressions means any combination of the items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, "first", "second", and the like are used to distinguish the functions and effects of the same items or similar items.

For example, a first data stream can pass through the traffic detection device 201a, and a second data stream can pass through the traffic detection device 201b, the first data stream and the second data stream are data streams of two different directions of a first service.

[0081] As a possible implementation manner, Figure 2 The traffic detection device (for example, the traffic detection device 201a and / or the traffic detection device 201b) in the communication network can be a SIG. For example, the traffic detection device can be a proprietary device with a SA capability, or the traffic detection device can be implemented by a BRAS+SA single board, or implemented by a SR+SA single board, or implemented by a PE+SA single board, or the traffic detection device is a DPI device.

[0082] As a possible implementation manner, in the case that the traffic detection device is implemented by a BRAS+SA single board, a SR+SA single board, or a PE+SA single board, the number of SA single boards in the traffic detection device can be one or more, and the present application does not limit this.

[0083] As a possible implementation manner, the service management device 202 can be a VBP.

[0084] As a possible implementation manner, Figure 2 The communication network shown can be Figure 1 The network structure shown, Figure 2 The traffic detection device 201a in the communication network can be Figure 1 The SIG 104a in the communication network, Figure 2 The traffic detection device 201b in the communication network can be Figure 1 The SIG 104b in the communication network, Figure 2 The management node in the communication network can be Figure 1 The VBP 107 in the communication network.

[0085] It should be understood that the above examples of the implementation manners of the communication network, the network, and the nodes in the network shown are illustrative, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Figure 1 and Figure 2 The communication network shown, and the implementation manners of the nodes in the network are illustrative, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Figure 1 and Figure 2The communication network shown can also be other types of network architecture / service scenarios, and the nodes therein can also be other types of devices. Those skilled in the art can know that, as network architectures evolve and new service scenarios emerge, the technical solutions provided by the embodiments of the present application are also applicable to similar network architectures.

[0086] The data processing method provided by the embodiments of the present application will be described below in conjunction with Figure 1 and Figure 2 the communication network shown. The actions and terms involved in the embodiments of the present application can be mutually referred to and are not limited. The message names or parameter names in the messages in the embodiments of the present application are only examples, and other names can also be used in specific implementations, which are not limited.

[0087] Figure 3 A flowchart of the data processing method provided by the present application is shown in Figure 3 , which can include the following steps S301 and S302.

[0088] S301, the first device acquires a first data feature of a first data stream and a second data feature of a second data stream. The first data stream is one of the uplink data stream or the downlink data stream of the first service, the second data stream is the other of the uplink data stream or the downlink data stream of the first service, and the transmission paths of the first data stream and the second data stream are different.

[0089] For example, the first data stream can be the uplink data stream of the first service, and the second data stream can be the downlink data stream of the first service. Alternatively, the first data stream can be the downlink data stream of the first service, and the second data stream can be the uplink data stream of the first service.

[0090] As a first possible implementation, the transmission path of the first data stream includes the first device, the transmission path of the second data stream includes the second device, and the first device and the second device are both flow detection devices. The implementation of the first device acquiring the first data feature and the second data feature can refer to the method flow shown in Figure 4 . Specifically, after receiving the first data stream, the first device can detect the first data stream to obtain the first data feature. After receiving the second data stream, the second device can detect the second data stream to obtain the second data feature. Moreover, the second device can send the second data feature detected by it to the first device. At this point, the first device can acquire the first data feature and the second data feature.

[0091] As a second possible implementation, the transmission path of the first data stream includes the first device, and the transmission path of the second data stream includes the second device, both the first device and the second device are traffic detection devices, and the implementation of the first device obtaining the first data feature and the second data feature can refer to the method flow shown in FIG. 4. Figure 5 As shown in the method flow. Among them, the first device can detect the first data stream to obtain the first data feature after receiving the first data stream. The second device can send the second data stream to the first device after receiving the second data stream. In this case, in addition to receiving the first data stream, the first device can also receive the second data stream. Then, the first device can also detect the second data stream to obtain the second data feature. At this point, the first device can obtain the first data feature and the second data feature.

[0092] As a third possible implementation, the transmission path of the first data stream includes the second device, and the transmission path of the second data stream includes the third device, both the second device and the third device are traffic detection devices, and the first device is a device other than the second device and the third device, and the implementation of the first device obtaining the first data feature and the second data feature can refer to the method flow shown in FIG. 5. Figure 6 As shown in the method flow. Among them, the second device can detect the first data stream to obtain the first data feature after receiving the first data stream. The third device can detect the second data stream to obtain the second data feature after receiving the second data stream. And the second device can send the obtained first data feature to the first device, and the third device can send the obtained second data feature to the first device. At this point, the first device can obtain the first data feature and the second data feature.

[0093] In the above three possible implementations, Figure 6 In the corresponding examples, the first device can be of the same type as the second device and the third device, that is, a traffic detection device. Alternatively, the first device can be a service management device, and the first device can manage the second device and the third device.

[0094] Based on the above three possible implementations, in the scenario of asymmetric routing of the bidirectional data stream of the first service, the traffic detection device of the same foreground or the service management device of the same background can still obtain the data features of the data streams of the two different directions of the first service.

[0095] S302, the first device merges the first data feature and the second data feature to obtain a third data feature.

[0096] It should be understood that the first data feature and the second data feature are respectively the data features of the data streams of two different directions of the first service. Therefore, the third data feature obtained by merging the first data feature and the second data feature can be considered as the complete data feature of the bidirectional data stream of the first service.

[0097] For example, as shown in Figure 4 , after detecting the first data feature of the first data stream and receiving the second data feature sent by the second device, the first device can combine the first data feature and the second data feature to obtain a third data feature.

[0098] For another example, as shown in Figure 5 , after detecting the first data feature of the first data stream and detecting the second data feature of the second data stream, the first device can combine the first data feature and the second data feature to obtain a third data feature.

[0099] For another example, as shown in Figure 6 , after receiving the first data feature sent by the second device and the second data feature sent by the third device, the first device can combine the first data feature and the second data feature to obtain a third data feature.

[0100] It should be understood that, if the first device in Figure 6 is a traffic management device, it means that the traffic management device combines the data features of the two unidirectional data streams of the first service. However, the traffic management device may not receive the data feature of the first data stream and the data feature of the second data stream at the same time. In this case, after the traffic management device first receives the data feature of one unidirectional data stream of the first service, it can first cache the data feature and not process it temporarily. Until the data feature of the other unidirectional data stream of the first service is received, the traffic management device combines the two data features.

[0101] As a possible implementation, with reference to Figure 4 and Figure 5 , after combining the first data feature and the second data feature to obtain a third data feature, the first device can further send the third data feature to the traffic management device. Then, the traffic management device can perform traffic management on the first service according to the third data feature.

[0102] As a possible implementation, in the case where the first device in Figure 6 is a traffic detection device, Figure 6 the method flow shown in the figure can be specifically as shown in Figure 7 . With reference to Figure 7 , after combining the first data feature and the second data feature to obtain a third data feature, the first device can further send the third data feature to the traffic management device. The traffic management device can perform traffic management on the first service according to the third data feature.

[0103] As a possible implementation, in the case where the first device in Figure 6 is a traffic detection device,Figure 6 The method flow as shown can further be as shown. Figure 8 Referring to Figure 8 , after the first device merges the first data feature and the second data feature to obtain the third data feature, the first device can further send the third data feature to the second device or the third device (the third device is taken as an example in Figure 8 ). The second device or the third device (the third device is taken as an example in Figure 8 ) can further send the third data feature to the service management device. The service management device can perform traffic management on the first service according to the third data feature.

[0104] As a possible implementation manner, in the case where the first device is the service management device in Figure 6 , the method flow as shown can further be as shown. Figure 6 The method flow as shown can further be as shown. Figure 9 Referring to Figure 9 , after the first device merges the first data feature and the second data feature to obtain the third data feature, the first device can perform traffic management on the first service according to the third data feature.

[0105] As a possible implementation manner, the service management device performing traffic management on the first service according to the third data feature can include at least one of the following: the service management device generates a traffic control policy of the first service according to the third data feature. Alternatively, the service management device records a traffic log of the first service according to the third data feature. The service management device performs security management on the traffic of the first service according to the third data feature.

[0106] It should be understood that, in the prior art, the background VBP will immediately process the data feature of the data stream reported by the foreground SIG after receiving the data feature. However, the data feature of the one-way data stream is incomplete, which will lead to inaccurate management by the VBP. In the embodiments of the present application, the service management device processes the complete data feature of the bidirectional data stream of the first service, so that the management of the service management device on the first service can be more accurate.

[0107] In summary, in the scenario of asymmetric routing of the bidirectional data flow of the first service, the same traffic detection apparatus can acquire data features of the two unidirectional data flows of the first service respectively, and can send the complete data features of the bidirectional data flow to the service management apparatus after merging the data features of the two unidirectional data flows. Alternatively, the service management apparatus can acquire data features of the two unidirectional data flows of the first service respectively, and can merge the data features of the two unidirectional data flows to obtain the complete data features of the bidirectional data flow. Further, the service management apparatus can perform traffic management on the first service according to the data features of the bidirectional data flow of the first service. Based on the above scheme, the problem that the detected data features are inaccurate in the current asymmetric routing scenario, and thus the effect of traffic management is poor, can be overcome.

[0108] As a possible implementation manner, the execution subject of the data processing method provided in the present application can be a node / device, or a functional component in the node / device, which is not limited in the present application. The functional component in the node / device can be a board card in the node / device, or a central processing unit (CPU) in the board card.

[0109] For example, in the method flow shown in Figure 3 or Figure 4 or Figure 5 , the first apparatus can be the SIG 104a in Figure 1 , or a functional component in the SIG 104a, the second apparatus can be the SIG 104b in Figure 1 , or a functional component in the SIG 104b, and the service management apparatus can be the VBP 107 in Figure 1 . Alternatively, the first apparatus can be the traffic detection apparatus 201a in Figure 2 , or a functional component in the traffic detection apparatus 201a, the second apparatus can be the traffic detection apparatus 201b in Figure 2 , or a functional component in the traffic detection apparatus 201b, and the service management apparatus can be the service management apparatus 202 in Figure 2 .

[0110] For example, in the method flow shown in Figure 7 or Figure 8 , the service management apparatus can be the VBP 107 in Figure 1 , the second apparatus can be the SIG 104a in Figure 1 , or a functional component in the SIG 104a, and the third apparatus can be the SIG 104b in Figure 1 , or a functional component in the SIG 104b. The first apparatus can be another SIG in Figure 1(not shown in the diagram), or other functional components in the SIG. Alternatively, the service management device can be... Figure 1 VBP 107 in the middle, the second device can be Figure 1 In SIG 104a, or the functional components in SIG 104a, the first and third devices can be Figure 1 The two independent boards or CPUs in the SIG 104b. Alternatively, the service management unit can be... Figure 2 The business management device 202 in the middle, the second device can be Figure 2 The flow detection device 201a, or a functional component of the flow detection device 201a, may be a third device. Figure 2 The first device can be any flow detection device 201b or a functional component of the flow detection device 201b, or other flow detection devices. Figure 2 (Not shown in the diagram) or other functional components in flow detection devices. Alternatively, the service management device can be a functional component in a flow detection device. Figure 2 The business management device 202 in the middle, the second device can be Figure 2 The flow detection device 201a, or the functional components of the flow detection device 201a, may be the first device and the third device. Figure 2 The traffic detection device 201b contains two independent boards or CPUs. Alternatively, the service management device can be... Figure 2 The business management device 202 in the middle, the first device and the second device can be Figure 2 The flow detection device 201a contains two independent boards or CPUs, and the third device can be... Figure 2 The flow detection device 201b or the functional component in the flow detection device 201b.

[0111] For example, in Figure 9 In the method flow shown, the first device can be Figure 1 VBP 107 in the middle, the second device can be Figure 1 The third device can be SIG 104a, or a functional component of SIG 104a. Figure 1 SIG 104b, or a functional component of SIG 104b. Alternatively, the first device can be... Figure 2 The business management device 202 in the middle, the second device can be Figure 2 The flow detection device 201a, or a functional component of the flow detection device 201a, may be a third device. Figure 2 The flow detection device 201b or the functional component in the flow detection device 201b.

[0112] As a possible implementation, when detecting the first data flow, the flow detection apparatus can detect at least one data packet in the first data flow. Thus, the first data feature can include a data feature of the at least one data packet in the first data flow. Similarly, when detecting the second data flow, the flow detection apparatus can detect at least one data packet in the second data flow. Thus, the second data feature can include a data feature of the at least one data packet in the second data flow.

[0113] As a possible implementation, the data feature identified by the flow detection apparatus for each data packet can include at least part of a feature field in the data packet. As an example, the data feature identified by the flow detection apparatus for each data packet can include at least one of the following information: flow identification, source internet protocol (IP) address, destination IP address, source media access control (MAC) address, destination MAC address, transmission protocol, source port, destination port, length of the data packet, arrival time of the data packet, payload content, payload length, payload manner, and the like.

[0114] As a possible implementation, the first apparatus can merge the first data feature and the second data feature based on a principle of taking a union set, and the third data feature obtained by the merging can include all feature fields in the first data feature and the second data feature. As an example, the first data feature can include a feature field A, a feature field B, a feature field C, and a feature field D, and the second data feature can include the feature field A, the feature field B, a feature field E, and a feature field F. Then, the third data feature obtained by the merging of the first data feature and the second data feature can include the feature field A, the feature field B, the feature field C, the feature field D, the feature field E, and the feature field F.

[0115] As a possible implementation, the first data feature and the second data feature both include a first feature field, and the third data feature obtained by the merging naturally includes the first feature field. The value of the first feature field in the third data feature can be determined according to the value of the first feature field in the first data feature and the value of the first feature field in the second data feature.

[0116] As an example, the first feature field can be a time delay type field. The value of the first feature field in the third data feature can be obtained by time delay calculation according to the value of the first feature field in the first data feature and the value of the first feature field in the second data feature.

[0117] As another example, the first feature field can be an accumulated type field. The value of the first feature field in the third data feature can be obtained by adding the value of the first feature field in the first data feature and the value of the first feature field in the second data feature.

[0118] As yet another example, the first feature field can be a decision type field. The value of the first feature field in the third data feature can be obtained by making a decision based on the first data feature and the second data feature. In a case where the decision cannot be made, the decision result of the first data feature or the decision result of the second data feature can be used as the value of the first feature field in the third data feature.

[0119] As a possible implementation, the direction of the first data flow can be considered as a first direction, and the direction of the second data flow can be considered as a second direction. The first direction and the second direction can be one of an uplink direction and a downlink direction. Figure 4 The first device in Figure 5 The second device in Figures 6 to 9 may receive data flows of multiple services in the first direction, and the first data flow is only one of the data flows. Figure 4 The second device in Figure 5 The third device in Figures 6 to 9 may receive data flows of multiple services in the second direction, and the second data flow is only one of the data flows.

[0120] As a possible implementation, Figure 4 The first device in Figure 5 The second device in Figures 6 to 9 may detect the first data feature from the first data flow, and the detection can include: Figure 4 The first device in Figure 5 The second device in Figures 6 to 9 may detect a first data feature set from data flows in the first direction received within a preset time window. The data flows in the first direction received within the preset time window include the first data flow, and the first data feature set includes the first data feature.

[0121] As a possible implementation, Figure 4 The second device in Figure 5 The third device in Figures 6 to 9 may detect the second data feature from the second data flow, and the detection can include: Figure 4 The second device in Figure 5 The third device in Figures 6 to 9The third device in the first device detects a second direction data stream received in a preset time window to obtain a second data feature set. The second direction data stream received in the preset time window includes the second data stream, and the second data feature set includes the second data feature.

[0122] As a possible implementation, the first device can obtain the first data feature set and the second data feature set, and the obtaining manner can be the same as the implementation of the first device obtaining the first data feature and the second data feature, which will not be repeated here. The first device merges the first data feature and the second data feature to obtain a third data feature, which can include: the first device merges the data features belonging to the same service in the first data feature set and the second data feature set to obtain a third data feature set. The third data feature set includes the third data feature, and the third data feature is obtained by merging the first data feature and the second data feature.

[0123] As a possible implementation, the first device can merge the first data feature set and the second data feature set according to the five-tuple information (i.e., transmission protocol, source IP, source port, destination IP, and destination port). It should be understood that the transmission protocol of the first direction data stream and the second direction data stream of the same service is the same. Moreover, the source IP and the source port of the first direction data stream of the same service are the same as the destination IP and the destination port of the second direction data stream of the same service. The destination IP and the destination port of the first direction data stream of the same service are the same as the source IP and the source port of the second direction data stream of the same service. Therefore, the first device can merge the data features belonging to the same service in the first data feature set and the second data feature set based on the five-tuple information.

[0124] As a possible implementation, for a hyper text transfer protocol (HTTP) type data stream, the first device can merge the first data feature set and the second data feature set according to an HTTP transaction. It should be understood that the data streams belonging to the same HTTP transaction belong to the same service. Therefore, the first device can merge the data features belonging to the same service in the first data feature set and the second data feature set according to the HTTP transaction.

[0125] In addition, there can be many other schemes for merging the data features of the data streams of the same service in the art, which are not limited by the present application.

[0126] It should be understood that, in the above description, Figure 4 and Figure 5In the scenario of FIG. 1, the data streams of the first direction and the second direction of the same service can not be received by the first device and the second device simultaneously within a preset time window. Or, in the scenario of FIG. 2, the data streams of the first direction and the second direction of the same service can not be received by the second device and the third device simultaneously within a preset time window. Thus, there can be data features of one-way data streams that cannot be merged in the first data feature set and the second data feature set. The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams. Figures 6 to 9 In the scenario of FIG. 1, the data streams of the first direction and the second direction of the same service can not be received by the first device and the second device simultaneously within a preset time window. Or, in the scenario of FIG. 2, the data streams of the first direction and the second direction of the same service can not be received by the second device and the third device simultaneously within a preset time window. Thus, there can be data features of one-way data streams that cannot be merged in the first data feature set and the second data feature set. The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams.

[0127] As a possible implementation manner, the first device in the method flow shown in FIG. 3 can further obtain the third data feature set corresponding to the preset time window from the second data feature set corresponding to the preset time window and the first data feature set corresponding to the preset time window. Figure 4 The first device in the method flow shown in FIG. 3 can further obtain the third data feature set corresponding to the preset time window from the second data feature set corresponding to the preset time window and the first data feature set corresponding to the preset time window. Figure 5 The second device in the method flow shown in FIG. 4 can further obtain the second data feature set corresponding to the preset time window from the data stream of the second direction received within the preset time window. Figures 6 to 9 The second device in the method flow shown in FIG. 4 can further obtain the second data feature set corresponding to the preset time window from the data stream of the second direction received within the preset time window. Figure 4 The second device in the method flow shown in FIG. 4 can further obtain the second data feature set corresponding to the preset time window from the data stream of the second direction received within the preset time window. Figure 5 The third device in the method flow shown in FIG. 5 can further obtain the second data feature set corresponding to the preset time window from the data stream of the second direction received within the preset time window. Figures 6 to 9 The third device in the method flow shown in FIG. 5 can further obtain the second data feature set corresponding to the preset time window from the data stream of the second direction received within the preset time window. The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams.

[0128] As a possible implementation manner, in the method flow shown in FIG. 3 or FIG. 4, the first device can further send the third data feature to the second device. Thus, the first device and the second device both have the third data feature, and the redundancy backup of the third data feature can be implemented. In addition, the first device and the second device can be configured with a master-slave relationship, the master device is configured to report the third data feature to a service management device in the background, and the standby device is configured to take over the work of the master device when the master device fails. Figure 4 The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams. Figure 5 The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams. The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams.

[0129] The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams. Figures 6 to 9 The third data feature set can include complete data features of merged two-way data streams, or data features of unmerged one-way data streams. Figure 4Taking the illustrated method flow as an example, in a specific embodiment, a data channel can be established between the first device and the second device, and a data protection mechanism (such as a remote backup service (RBS) mechanism) can be deployed to enable synchronization of third data features between the first device and the second device. Additionally, a master-slave control protocol (such as a virtual router redundancy protocol (VRRP)) can be configured on the first device and the second device to control the master-slave relationship between the first device and the second device.

[0130] As one possible implementation method, in Figure 5 or Figure 4 In the illustrated method flow, the first device can also send the third data feature to the second and third devices. Thus, both the second and third devices possess the third data feature, enabling redundant backup of the third data feature. Furthermore, the second and third devices can be configured in a primary / backup relationship, with the primary device reporting the third data feature to the backend business management device, and the backup device taking over the primary device's operation in case of a failure.

[0131] by Figure 5 or Figure 7 Taking the illustrated method flow as an example, in a specific embodiment, a data channel can be established between the second and third devices, and a data protection mechanism can be deployed to enable synchronization of third data features between the second and third devices. Additionally, a master-slave control protocol can be configured on the second and third devices to control their master-slave relationship.

[0132] As one possible implementation method, in Figure 8 In the illustrated embodiment, the second device sends a second data stream to the first device, which may specifically include: the second device redirecting the second data stream to the first device. Subsequently, the second data stream may be forwarded by the first device to the destination.

[0133] For example, with Figure 7 Taking the network architecture shown as an example, SIG 104a can be a first device, SIG 104b can be a second device, and a schematic diagram of the second device sending a second data stream to the first device can be shown as follows. Figure 8 As shown. Reference Figure 5The first data stream from user equipment 101 can be transmitted to the network side sequentially through user access equipment 102, router 103a, SIG 104a, router 105a, and CR 106. The second data stream from the network side can reach SIG 104b sequentially through CR 106 and router 105b. SIG 104b can redirect the second data stream to SIG 104a, and subsequently, the second data stream can reach user equipment 101 sequentially through router 103a and user access equipment 102. Thus, SIG 104a can receive both the first and second data streams.

[0134] As one possible implementation method, in Figure 1 In the illustrated embodiment, the second device sends a second data stream to the first device. Specifically, this may include the second device copying the second data stream and sending it to the first device. The second device can either forward the second data stream along its original path or send it directly to the first device. The first device can simply detect the second data stream from the second device without forwarding it.

[0135] For example, with Figure 10 Taking the network architecture shown as an example, SIG 104a can be a first device, SIG 104b can be a second device, and a schematic diagram of the second device sending a second data stream to the first device can also be shown as follows. Figure 10 As shown. Reference Figure 5 The first data stream from user equipment 101 can be transmitted to the network side sequentially through user access equipment 102, router 103a, SIG 104a, router 105a, and CR 106. The second data stream from the network side can be transmitted to user equipment 101 sequentially through CR 106, router 105b, SIG 104b, router 103b, and user access equipment 102. Additionally, SIG 104b can copy the received second data stream and forward it to SIG 104a. Therefore, SIG 104a can receive both the first and second data streams.

[0136] As one possible implementation, in a scenario where the second device sends a second data stream to the first device, the first device detects and reports the data characteristics of the data stream. The first device can acquire first and second data characteristics, and can combine the first and second data characteristics into a third data characteristic before reporting it to the business management device. For example, refer to... Figure 1 and Figure 11 SIG 104a can report third data features to VBP 107.

[0137] As a possible implementation, in the scenario where the second device sends the second data stream to the first device, the second device can also detect the second data feature of the second data stream, and can report the second data feature to the service management device.
