[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0026] The embodiments of the present application provide a data transmission method, which is applied to a first node in a network topology, the network topology further comprising a second node, Figure 1 An optional flowchart of a data transmission method provided in an embodiment of the present application is shown in Figure 1 The data transmission can include:

[0027] S101: When data is transmitted to the second node by using a shortest path from the first node to the second node, an identifier of a data transmission performance of a first network card of the first node is acquired.

[0028] At present, the first node in the network topology usually transmits data by using the shortest path from the first node to the second node. However, due to many interference factors of the heterogeneous network, the shortest path will change with the change of the load of the service data and the change of the interference factors, thereby affecting the data transmission efficiency.

[0029] In order to improve the data transmission efficiency in the heterogeneous network, in the embodiments of the present application, when the first node needs to transmit data to the second node, the data is transmitted to the second node by using the shortest path from the first node to the second node, wherein the shortest path comprises the first network card. In order to prevent the phenomenon of low data transmission efficiency caused by the low data transmission performance of the first network card of the first node in the shortest path, when the first node transmits data by using the shortest path, an identifier of the data transmission performance of the first network card is acquired, the identifier is used to indicate the data transmission performance of the first network card, and the data transmission performance of the first network card can be divided into abnormal and normal, and of course, the specific conditions of the abnormal can be classified, for example, the degree of abnormal can be divided into serious, moderate, slight and the like. Herein, the embodiments of the present application do not make a specific limitation.

[0030] The first node and the second node can be devices of the network topology in the heterogeneous network, which can be terminal devices, such as smart phones, smart televisions, smart speakers, and can also be routing devices, such as routers. Herein, the embodiments of the present application do not make a specific limitation.

[0031] It should be noted that the first node comprises not only the first network card but also other network cards, and in the heterogeneous network, the first node can transmit data to the second node by using a path constituted by the first network card and / or other network cards.

[0032] In addition, the identification of the data transmission performance of the first network card can be determined by a data transmission performance parameter of the first network card, where the data transmission performance parameter of the first network card can be throughput, and / or packet sending delay, and / or packet loss rate, and the like, which are not limited herein.

[0033] In this way, the data transmission performance of the first network card on the shortest path can be known by using the obtained identification of the data transmission performance of the first network card, so that the abnormal situation can be processed in time.

[0034] In order to obtain the identification of the data transmission performance of the first network card, in an optional embodiment, S101 can include:

[0035] When data is transmitted to the second node by using the shortest path from the first node to the second node, a monitoring value of the data transmission performance of the first network card is obtained.

[0036] The monitoring value of the data transmission performance of the first network card is determined as the identification of the data transmission performance of the first network card.

[0037] That is, when the first node transmits data by using the shortest path, the monitoring value of the data transmission performance of the first network card is obtained, and it should be noted that the monitoring value of the data transmission performance of the first network card can be obtained in real time, or can be obtained periodically, which is not limited herein.

[0038] After the monitoring value of the data transmission performance of the first network card is obtained, the monitoring value of the data transmission performance of the first network card is determined as the identification of the data transmission performance of the first network card, and the monitoring value of the data transmission performance of the first network card is used to determine whether the data transmission performance of the first network card is abnormal, that is, the condition of the data transmission performance of the first network card is determined by monitoring the data transmission performance of the first network card, and then the target path containing the network card other than the first network card in the first node can be selected in time when the abnormality occurs, so that the target path is used to transmit the to-be-transmitted data.

[0039] In order to determine the monitoring value of the data transmission performance of the first network card, in an optional embodiment, the above method can further include:

[0040] The throughput, packet sending delay and packet loss rate of the first network card are obtained.

[0041] The monitoring value of the data transmission performance of the first network card is determined according to the throughput, packet sending delay and packet loss rate of the first network card.

[0042] Here, the first node obtains the throughput, packet sending delay and packet loss rate of the first network card, and based on the throughput, packet sending delay and packet loss rate of the first network card, the monitoring value of the data transmission performance of the first network card can be directly determined by using a table lookup method, or the monitoring value of the data transmission performance of the first network card can be determined by using a weighted summation algorithm. Here, the embodiments of the present application do not make a specific limitation.

[0043] S102: When the identifier of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is abnormal, selecting a target path from the paths from the first node to the second node;

[0044] After obtaining the monitoring value of the data transmission performance of the first network card, it is determined whether the identifier of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is abnormal. Only when the identifier of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is abnormal, it means that the transmission performance of the first network card on the shortest path is poor at this time, and the shortest path containing the first network card is not suitable for transmitting data. Therefore, here, a target path is selected from the paths from the first node to the second node, wherein the target path is a path containing network cards other than the first network card in the first node; that is, the first network card is not used to transmit data, but the target path containing network cards other than the first network card in the first node is used to transmit the to-be-transmitted data, so that the data transmission efficiency can be improved.

[0045] When the monitoring value of the data transmission performance of the first network card is used as the identifier of the data transmission performance of the first network card, in order to determine whether the data transmission performance of the first network card is abnormal, in an optional embodiment, the above method can further include:

[0046] When the monitoring value of the data transmission performance of the first network card is greater than the threshold value of the data transmission performance of the first network card, it is determined that the identifier of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is abnormal;

[0047] When the monitoring value of the data transmission performance of the first network card is less than the threshold value of the data transmission performance of the first network card, it is determined that the identifier of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is not abnormal.

[0048] Here, by judging the relationship between the monitoring value of the data transmission performance of the first network card and the threshold value of the data transmission performance of the first network card, it is determined whether the data transmission performance of the first network card is abnormal. If the monitoring value of the data transmission performance of the first network card is greater than the threshold value of the data transmission performance of the first network card, it means that the data transmission load of the first network card is large enough to affect the data transmission efficiency. Therefore, at this time, the identifier of the data transmission performance of the first network card is determined to indicate that the data transmission performance of the first network card is abnormal. If the monitoring value of the data transmission performance of the first network card is less than the threshold value of the data transmission performance of the first network card, it means that the data transmission load of the first network card is within the moving range and has little effect on the data transmission efficiency. Therefore, at this time, the identifier of the data transmission performance of the first network card is determined to indicate that the data transmission performance of the first network card is not abnormal.

[0049] In addition, it should be noted that for the case that the monitoring value of the data transmission performance of the first network card is equal to the threshold value of the data transmission performance of the first network card, the identifier of the data transmission performance of the first network card can be determined to indicate that the data transmission performance of the first network card is abnormal, or the identifier of the data transmission performance of the first network card can be determined to indicate that the data transmission performance of the first network card is not abnormal. Here, the present embodiment does not make specific limitation.

[0050] In addition, in order to obtain the threshold value of the data transmission performance of the first network card, in an optional embodiment, the above method can further include:

[0051] According to the hardware parameters and the anti-interference capability parameters of the first network card, an evaluation value of the data transmission performance of the first network card is determined.

[0052] The product of the evaluation value of the data transmission performance of the first network card and the preset percentage threshold value is determined as the threshold value of the data transmission performance of the first network card.

[0053] It can be understood that the threshold value of the data transmission performance of the first network card can be pre-set or determined in real time. Here, the present embodiment does not make specific limitation.

[0054] In order to determine the threshold value of the data transmission performance of the first network card, the hardware parameters and the anti-interference capability parameters of the first network card are first obtained, and then the evaluation value of the data transmission performance of the first network card is determined according to the two parameters. Here, the evaluation value of the data transmission performance of the first network card can be determined by table lookup according to the two parameters, or the evaluation value of the data transmission performance of the first network card can be determined by using weighted summation algorithm according to the two parameters. Here, the present embodiment does not make specific limitation.

[0055] After the evaluation value of the data transmission performance of the first network card is determined, the evaluation value of the data transmission performance of the first network card is multiplied by a preset percentage threshold value, so that the threshold value of the data transmission performance of the first network card can be obtained. Here, the preset percentage threshold value can be set according to requirements and can be modified according to requirements, so as to meet the heterogeneous network under different conditions.

[0056] In order to select the target path for transmitting the to-be-transmitted data, in an optional embodiment, S102 can include:

[0057] When the identification of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is abnormal, the path corresponding to the minimum value of the substitution value in the path from the first node to the second node is determined as the target path.

[0058] Here, when the identification of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is abnormal, in order to select the target path from the path from the first node to the second node to transmit data to improve transmission efficiency, the path corresponding to the minimum value of the substitution value in the path from the first node to the second node is determined as the target path. For example, for the first node, in addition to the first network card, it also includes a second network card and a third network card. The path containing the second network card has a smaller substitution value than the path containing the third network card. Therefore, the path containing the second network card is determined as the target path.

[0059] In this way, the path corresponding to the minimum value of the substitution value in the path from the first node to the second node is used to transmit the to-be-transmitted data, which is beneficial to further improve the transmission efficiency of the data.

[0060] S103: transmitting the to-be-transmitted data to the second node by using the target path.

[0061] After the target path is selected, the to-be-transmitted data is transmitted to the second node by using the target path. That is, when the data transmission performance of the first network card is abnormal, the path containing the network card other than the first network card in the first node is selected from the path from the first node to the second node to transmit the to-be-transmitted data, and the load of the first network card is shared to other network cards in the first node, which helps to improve the transmission efficiency of the data.

[0062] In order to realize the transmission of the to-be-transmitted data by using the target path, here, the to-be-transmitted data can be transmitted only by using the target path, or the to-be-transmitted data can be transmitted by using the shortest path and the target path. Here, the embodiments of the present application do not make specific limitation on this.

[0063] For the case of transmitting the to-be-transmitted data by using the shortest path and the target path, in an optional embodiment, S103 can include:

[0064] transmitting, by using the shortest path, a first data packet of the to-be-transmitted data to the second node;

[0065] transmitting, by using the target path, a second data packet of the to-be-transmitted data to the second node.

[0066] That is, here, the to-be-transmitted data can be transmitted to the second node by using the shortest path and the target path at the same time, wherein the to-be-transmitted data is split into two data packets, i.e., the first data packet and the second data packet, the first data packet is transmitted to the second node by using the shortest path, and the second data packet is transmitted to the second node by using the target path, so that when the data transmission performance of the first network card on the shortest path is abnormal, the target path is used to share the transmission pressure of the shortest path, and the transmission efficiency of data is improved.

[0067] Further, in order to split the to-be-transmitted data to obtain the first data packet and the second data packet, in an optional embodiment, the method can further include:

[0068] when the size of the to-be-transmitted data packet is greater than a preset threshold, splitting the to-be-transmitted data packet into the first data packet and the second data packet;

[0069] That is, for the case that the size of the to-be-transmitted data packet is greater than a preset threshold, since the to-be-transmitted data packet is large, the to-be-transmitted data packet can be split into two data packets, wherein the size of the first data packet is greater than the size of the second data packet; here, the first data packet with a larger size is transmitted by using the shortest path, and the second data packet with a smaller size is transmitted by using the target path, so as to share the transmission pressure of the shortest path, and the data transmission efficiency is improved.

[0070] In addition, for the case of transmitting the to-be-transmitted data by using the shortest path and the target path, in an optional embodiment, S103 can include:

[0071] transmitting, by using the shortest path, a first service type data packet of the to-be-transmitted data to the second node;

[0072] transmitting, by using the target path, a second service type data packet of the to-be-transmitted data to the second node.

[0073] That is to say, here, the shortest path and the target path can be used simultaneously to transmit the to-be-transmitted data to the second node, wherein the to-be-transmitted data is split into two data packets, i.e., the data packet of the first service type and the data packet of the second service type, and then the data packet of the first service type is transmitted to the second node by using the shortest path, and the data packet of the second service type is transmitted to the second node by using the target path, so that when the data transmission performance of the first network card on the shortest path is abnormal, the target path is used to share the transmission pressure of the shortest path, and the transmission efficiency of data is improved.

[0074] Further, in order to split the to-be-transmitted data to obtain the data packet of the first service type and the data packet of the second service type, in an optional embodiment, the method can further include:

[0075] When the size of the to-be-transmitted data packet is less than the preset threshold, the to-be-transmitted data packet is split into the data packet of the first service type and the data packet of the second service type.

[0076] That is to say, for the case that the size of the to-be-transmitted data packet is less than the preset threshold, since the to-be-transmitted data packet is small, the to-be-transmitted data packet can be split into two data packets of service types; wherein the service types can include a video type, an audio type and a file type; here, the data packet of the first service type is transmitted by using the shortest path, and the data packet of the second service type is transmitted by using the target path, for example, the first service type can be a video type, and the second service type can be an audio type and a file type; in this way, the transmission pressure of the shortest path is shared, and the data transmission efficiency is improved.

[0077] In addition, for the case that the identification of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is not abnormal, in an optional embodiment, the method can further include:

[0078] When the identification of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is not abnormal, the shortest path is determined as the target path.

[0079] It can be understood that when the identification of the data transmission performance of the first network card indicates that the data transmission performance of the first network card is not abnormal, that is, the capability of the shortest path for transmitting data is still acceptable, the shortest path is determined as the target path, that is, the shortest path is still used to transmit the to-be-transmitted data, so that the transmission rate is ensured.

[0080] The data transmission method in one or more embodiments is described below by taking examples.

[0081] In this example, in the scenario of a heterogeneous network, each device node can have multiple network cards participating in networking and data transmission, so there are multiple reachable network paths between devices. The minimum cost path between each pair of devices is selected to build a link state database (LSDB), and the shortest path is calculated based on the LSDB using a shortest path routing algorithm to build the routing table information (R_Info) of the entire topology.

[0082] Here, considering the unstable network quality of a heterogeneous network, multiple interference factors, and the probability of network congestion being higher than that of a homogeneous network, in addition to saving the minimum cost path between devices, one or more alternative paths (if any) are saved when building the LSDB. In this way, when the network quality fluctuates, the alternative path can be switched to, or in the case of large data transmission, multiple paths can be selected for parallel transmission at the service layer to improve the efficiency of data transmission and the use efficiency of various types of network interfaces in a heterogeneous network.

[0083] Figure 2 An optional structure diagram of an example of a first node in a network topology provided by an embodiment of the present application is shown in Figure 2 As shown, a network real-time state monitoring module and a network card performance evaluation module are added to each device node in a heterogeneous network. In addition, each device (network device node) also includes a network card physical parameter module, an anti-interference capability module, a throughput module, a packet delay module, a packet loss rate module, a network card A, a network card B, a network card C, and the like.

[0084] Network real-time state monitoring module: According to parameters such as throughput, packet delay, and packet loss rate, the network path quality on the device node is scored in real time, and the current throughput index Cur-ThroughPut-Score is output.

[0085] Network card performance evaluation module: According to the hardware parameters and anti-interference capability of the network card, the performance of each network card on the device node is evaluated, and the ThroughPut-Score index and the Backup-ThroughPut-Score index are output for each network card.

[0086] ThroughPut-Score: The throughput score value evaluated by combining the performance and anti-interference properties of the network card. The higher the score, the better the performance of the network card. In practical applications, the value range is [0, 100].

[0087] Backup-ThroughPut-Percent: the trigger threshold of seeking backup network path, which is a percentage value, such as a%, when Cur-ThroughPut-Score is greater than ThroughPut-Score*a%, it means that the network quality of the network port has deteriorated or the occupation of network resources is relatively high, and the alternative network path can be sought or the alternative network path is switched.

[0088] The network real-time state monitoring module evaluates the network state of the network card according to the set time period T, so that Cur-ThroughPut-Score can be obtained, and by comparison, when Cur-ThroughPut-Score >= (ThroughPut-Score*Backup-ThroughPut-Percent), the network port switching network exit (edge) or the selection of enabling the alternative network is triggered, so that the transmission performance of the whole heterogeneous network is optimized by updating the routing table in a local manner.

[0089] Figure 3 An optional network topology example structure provided for the embodiment of the present application Figure 1 As shown in Figure 3 , a topology diagram of a heterogeneous network constructed by four devices (Device A, Device B, Device C and Device D) is given: each device node has two network cards (if*0 and if*1) participating in the heterogeneous network networking, and the corresponding IP addresses are IP*0 and IP*1, respectively. The double-headed arrow in the device node indicates that the two network cards in the device are interconnected and the cost is negligible.

[0090] According to the traditional routing calculation method: only the edge with cost == 4 between Device B and Device A is reserved: the ifb1 network port of Device B to the ifa1 network port of Device A. Only the edge with cost == 2 between Device A and Device C is reserved: the ifa0 network port of Device A to the ifc1 network port of Device C.

[0091] In this example, Device B and Device A will save information about the edge with cost == 5 (Device B's ifb0 network port to Device A's ifa0 network port), and similarly Device A and Device C will save information about the edge with cost == 3.

[0092] Taking the shortest path calculation from Device B to Device D as an example, there are two routing options:

[0093] Route one: DeviceB(ifb1)-->DeviceA(ifa1)-->DeviceA(ifa0)-->DeviceC(ifc1)-->DeviceD(ifd1). The cost of the path represented by route one is: 4+2+2=8;

[0094] Route two: DeviceB(ifb1)-->DeviceD(ifd0). The cost of the path represented by route two is: 10.

[0095] Therefore, the shortest path (the path with the minimum cost) selected from DeviceB to DeviceD is the path represented by route one, Figure 4 a structure diagram of an example of an optional network topology provided for an embodiment of the present application Figure 2 As shown in Figure 4 the dashed line represents the path of route one.

[0096] When the path with cost == 4 between DeviceA and DeviceB triggers the switching backup path mechanism, for ifb1 of DeviceA, if Cur-ThroughPut-Score >=(ThroughPut-Score*Backup-ThroughPut-Percent) is obtained through comparison, the path with cost == 5 between DeviceA and DeviceB is selected to update the routing table information, so that subsequent data can be transmitted between DeviceA and DeviceB through the path with cost == 5, Figure 5 a structure diagram of an example of an optional network topology provided for an embodiment of the present application Figure 3 As shown in Figure 5 the dashed line represents the path of route one.

[0097] Figure 6 a structure diagram of an example of an optional network topology provided for an embodiment of the present application Figure 4 As shown in Figure 6 When the service party of the heterogeneous network needs to perform large data transmission, for ifb1 of DeviceA, Cur-ThroughPut-Score >=(ThroughPut-Score*Backup-ThroughPut-Percent), triggering the backup route calculation based on LSDB, outputting the backup route R_BackUp_Info (the cost of which is greater than the routing information represented by R_Info, refer to Figure 6The route path represented by the dotted line corresponds to R_Info, and the route path represented by the dash-dot line corresponds to R_BackUp_Info. The data is packetized at the service layer, and the data packets are transmitted through the two paths of R_Info and R_BackUp_Info respectively, and the data packets are recovered at the receiving end.

[0098] As shown in FIG. 5, Device B transmits 500M data to Device D. The data packets can be divided into five packets, each of which is 100M. Data packet 0, data packet 1, and data packet 2 are transmitted through the route path represented by the dotted line, and data packet 4 and data packet 5 are transmitted through the route path represented by the dash-dot line. Thus, the receiving end (Device D) receives the data packets through the two network interfaces ifd0 and ifd1, and the data packets are recovered to obtain the complete service data. Figure 6 When the data volume is small, the data of service flow a is transmitted through the route path represented by the dotted line, and the data of service flow b is transmitted through the route path represented by the solid line.

[0099] In this example, the network real-time state monitoring module and the network card performance evaluation module are added in the device node. In the case of fluctuation of the heterogeneous network, the alternative path is switched locally to improve the data output efficiency. In the case of large data transmission, the multi-path parallel transmission is selected to improve the efficiency. In the case of frequent small data transmission, the alternative path is enabled for parallel transmission to improve the efficiency and the utilization rate of the network card.
