[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] Embodiment 1 of the present invention provides a data transmission path selection method, the method is used to determine the data transmission path when a first data source transmits target data to a second data source, such as Figure 1 As shown, the method comprises the following steps:

[0036] S100, obtaining an initial link list set, wherein the initial link list set includes a plurality of initial link lists, wherein the initial link list includes a plurality of initial links on the same initial path, and the initial links are links established between a first data party and a second data party.

[0037] Specifically, the initial link list set A = {A1, A2, ..., A i , …, A m}, the i-th initial link list A i ={A i1 , A i2 , …, A ij, …, A in}, A ij It is the jth initial link in the ith initial link list. The value range of i is 1 to m, the value range of j is 1 to n, m is the number of initial link lists, n is the number of initial links in the initial link list, the initial link is the initial Link, the initial path is the initial PATH, and the ith initial link list is the list of initial links included in the ith initial path.

[0038] S200, obtaining delay data and jitter data of the initial link, and based on the delay data and jitter data of the initial link, obtaining the initial consumption time required for the initial link to transmit the target data, thereby obtaining an initial consumption time list. Specifically, those skilled in the art know that any method of obtaining delay data and jitter data of the initial link in the prior art belongs to the protection scope of the present invention and will not be described in detail herein.

[0039] Specifically, based on obtaining the transmission rate of the initial link, the initial consumption time is obtained based on the size a1 of the target data, the transmission rate a2, the delay data a3 and the jitter data a4. The initial consumption time = a1 / a2+a3+k×a4, where k is a proportional coefficient, which can be determined according to actual needs.

[0040] S300, obtaining a target consumption time list, wherein the target consumption time list includes several target consumption times, wherein the target consumption time is an initial consumption time in the initial consumption time list whose corresponding value is greater than a preset transmission threshold, and the difference between any two target consumption times is less than a preset error threshold.

[0041] Specifically, the initial consumption time list T = {T1, T2, ..., T r ,…,T s}, T r is the rth initial consumption time, the value range of r is 1 to s, s = m × n; the target consumption time list AT = {AT1, AT2, ..., AT g1 ,…,AT g2 ,…,AT z}, AT g1 Consumes time for the g1th target and AT g1 >Preset transmission threshold AT0, AT g2 The g2th target consumption time, g1 ranges from 1 to z, g2 ranges from 1 to z, z is the amount of target consumption time and z ≤ s, |AT g1 -AT g2|<preset error threshold T0, T0 can be set according to actual needs. By selecting the initial link with roughly the same transmission time of the target data from the first data side to the second data side, the target data does not need to wait too much time for reorganization after transmission, thereby optimizing the transmission steps.

[0042] S400, obtaining an initial link corresponding to the target consumption time as a first intermediate link, and obtaining intermediate packet loss data of the first intermediate link, and using the first intermediate link corresponding to the intermediate packet loss data that satisfies a preset packet loss rule as a second intermediate link, wherein the intermediate packet loss data includes the number of packet losses and the packet loss rate. Specifically, those skilled in the art know that any method of obtaining the number of link packet losses and the packet loss rate in the prior art belongs to the protection scope of the present invention, and will not be described in detail herein.

[0043] S500: If the link bandwidth of the second intermediate link is greater than a preset link bandwidth threshold, the second intermediate link is used as a candidate target link. The preset link bandwidth threshold can be set according to actual needs to meet the minimum requirement of transmission bandwidth.

[0044] S600, selecting an alternative target link based on the line type of the alternative target link, and obtaining a final target path for transmitting target data from a first data party to a second data party, wherein the line type includes MPLS, INTERNET, 4G and 5G.

[0045] In summary, an initial link list set is obtained, delay data and jitter data of the initial link are obtained, and based on the delay data and jitter data of the initial link, the initial consumption time required for the initial link to transmit the target data is obtained, thereby obtaining an initial consumption time list, obtaining a target consumption time list, obtaining the initial link corresponding to the target consumption time as the first intermediate link, and obtaining the intermediate packet loss data of the first intermediate link, and using the first intermediate link corresponding to the intermediate packet loss data that meets the preset packet loss rule as the second intermediate link. If the link bandwidth of the second intermediate link is greater than the preset link bandwidth threshold, the second intermediate link is used as an alternative target link, and the alternative target link is selected based on the line type of the alternative target link to obtain a final target path for transmitting target data from the first data direction to the second data party. The present invention screens the initial link by delay, jitter, number of packet losses, transmission rate, etc., thereby obtaining the final target path, ensuring the safe and fast transmission of target data from multiple dimensions, and saving the waiting time for reorganization of the target data after reaching the second data party.

[0046] Specifically, Figure 2 As shown, in S600, selection is made based on the line type of the candidate target link to obtain the final target path, including:

[0047] S610: Acquire all candidate target paths based on the candidate target links, where the candidate target paths are data transmission paths for transmitting target data from a first data source to a second data source.

[0048] S620, obtaining the line type of each candidate target link in the candidate target path, and taking the candidate target path with the largest number of the same line types as the final target path.

[0049] Specifically, obtain the alternative target path B t = {B t1 , B t2 , …, B te , …, B th}, B te is the e-th candidate target link in the t-th candidate target path, t ranges from 1 to b, b is the number of candidate target paths, e ranges from 1 to h, h is the number of candidate target links, obtain B t The maximum number of corresponding lines of the same type C t , get C0 = max{C1, C2, ..., C t , …, C b}Take the alternative target path corresponding to C0 as the final target path.

[0050] Specifically, by taking the candidate target paths with the largest number of the same line type as the final target path, the same line type no longer needs to perform operations such as protocol conversion when transmitting, thereby improving transmission efficiency.

[0051] In one embodiment of the present invention, the candidate target path with the least number of the same line type is used as the final target path. t The minimum number of corresponding lines of the same type D t , get D0 = min{D1, D2, ..., D t , …, D b}Use the alternative target path corresponding to D0 as the final target path. By using the alternative target path with the least number of the same line type as the final target path, the comprehensiveness of the line type is ensured, and paralysis caused by a problem of a certain line type is avoided.

[0052] Specifically, obtaining the final target path for the first data party to transmit the target data to the second data party further includes: determining the final target path to use the TCP protocol or the UDP protocol for transmission according to the service type of the target data.

[0053] Further, such as Figure 3 As shown, S300 also includes determining a preset transmission threshold through the following steps:

[0054] S310: When the network topology corresponding to the network node of the initial link is a star topology, the preset transmission threshold is a preset fixed value. Specifically, the preset fixed value is x1.

[0055] S320: When the network topology corresponding to the network nodes of the initial link is a mesh topology, the number of network nodes corresponding to all initial links is obtained as an initial number. Specifically, the initial number is x2.

[0056] S330, based on the initial number, determine the number of intermediate links formed when the network nodes are in a star topology, wherein the number of intermediate links is the number of links of the initial number of network nodes forming the star topology. Specifically, in one embodiment of the present invention, the number of intermediate links is x3=x2-1.

[0057] S340: Determine a preset transmission threshold based on the number of intermediate links and the number of initial links.

[0058] Specifically, based on the number of intermediate links and the number of initial links, a preset transmission threshold is determined, wherein the preset transmission threshold satisfies the following condition: the ratio of the preset transmission threshold to the preset fixed value is equal to the ratio of the number of initial links to the number of intermediate links. That is, the preset transmission threshold = m×n×x1 / x3.

[0059] In summary, when the network topology corresponding to the network nodes of the initial link is a star topology, the preset transmission threshold is a preset fixed value; when the network topology corresponding to the network nodes of the initial link is a mesh topology, the number of network nodes corresponding to all initial links is obtained, and based on the number of network nodes, the number of intermediate links that can be formed when the network nodes are in a star topology is determined, and the preset transmission threshold is determined based on the number of intermediate links and the number of initial links. Under the same network nodes, the mesh topology forms more initial links than the star topology, and has more transmittable routes. Therefore, when determining the preset fixed value, the preset transmission threshold of the mesh topology is greater than the preset fixed value, which makes the preset transmission threshold more reasonable.

[0060] Further, such as Figure 4 As shown, after S100 obtains the initial link list set, the following steps are also included:

[0061] S101 , for any initial link list, obtaining an initial link as a designated link through a preset allocation method, thereby obtaining a designated link list.

[0062] S102, obtaining a final target path based on the specified link list.

[0063] Furthermore, Figure 5 As shown, S101 obtains an initial link as a designated link through a preset allocation method, including the following steps:

[0064] S1011: For any initial link list, obtain an initial link ID corresponding to each initial link and the number of initial links in the initial link list. The initial link ID is a unique identifier of the initial link.

[0065] S1012, obtaining target quintuple information when target data is transmitted from the first data party to the second data party.

[0066] S1013, perform hash mapping on the target five-tuple information to obtain a target hash value y1.

[0067] S1014, initialize the starting value y2.

[0068] S1015, obtaining a designated link ID and obtaining a designated link based on the designated link ID, wherein the designated link ID satisfies the following conditions: the designated link ID is equal to the sum of the value obtained by dividing the target hash value by the target difference value and the start value, and the target difference value is the difference between the number of initial links and the start value. That is, the initial link ID = y1% (n-y2) + y2.

[0069] In summary, for any initial link list, obtain the initial link ID corresponding to each initial link and the number of initial links in the initial link list, obtain the target five-tuple information when the target data is transmitted from the first data party to the second data party, perform hash mapping on the target five-tuple information, obtain the target hash value, initialize the starting value, obtain the specified link ID and obtain the specified link based on the specified link ID, and obtain the final target path based on the specified link list.
