[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] With the rapid development of Internet technology, the SDN (Software Defined Network) network architecture separates control from forwarding, centralizes the control logic of each device in the network on a computing device, and thus improves the network management and configuration capabilities. Based on this, enterprise data centers gradually adopt SDN architecture deployment, that is, each data center can have a server for deploying SDN controllers. These data centers are located in different locations and have different SDN configurations. To achieve coordinated operation, they need to exchange information with each other, which leads to the need for interconnection between data centers. At present, the interconnection between data centers is usually achieved by manually formulating interconnection strategies. However, this method that relies on human subjective consciousness cannot guarantee the comprehensiveness and accuracy of the interconnection plan, and thus cannot guarantee the reliability of the interconnection between data centers.

[0030] Therefore, the embodiment of the present application provides a data center interconnection method, which can be applied in the application environment shown in FIG1. ​​It includes a general control center 102 of the SDN network, and the general control center 102 can be connected to the SDN controller 106 deployed in each data center 104. Multiple network devices 108 can be deployed under the data center 104, and the interconnection between data centers can also be understood as the interconnection between network devices under the data center. Among them, the network device 108 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers and Internet of Things devices.

[0031] Exemplarily, in response to the user-initiated interconnection instruction between multiple data centers 104, the general control center 102 can first instruct each SDN controller 106 to obtain the network device information of each network device 108 deployed in its corresponding data center 104, as well as the communication mechanism information of each communication mechanism of the data center 104 when performing network communication, and exchange information with other SDN controllers 106. Each SDN controller 106 negotiates the interconnection plan based on the information of each network device and each communication mechanism information to obtain multiple candidate interconnection plans. Then each SDN controller 106 further obtains the interconnection requirements indicated by the interconnection instruction, and selects the target interconnection plan that matches the interconnection requirements from each candidate interconnection plan. Finally, each SDN controller 106 sends the target interconnection plan to the corresponding target network device, instructing the target network device to interconnect based on the target communication mechanism in the target interconnection plan, thereby realizing the interconnection between multiple data centers 104.

[0032] In an exemplary embodiment, as shown in FIG. 2 , a data center interconnection method is provided, which is described by taking the method applied to the general control center 102 in FIG. 1 as an example, including:

[0033] Step S202, in response to the interconnection instruction between multiple data centers, respectively obtain the network device information of each network device deployed in each data center and the communication mechanism information of each communication mechanism of each data center when performing network communication.

[0034] Among them, the interconnection instruction refers to the instruction for at least two data centers to connect. Each data center can deploy at least one network device. The network device refers to the terminal device deployed in the data center. The network device information can refer to the basic information of the network device, such as device model, device type, memory, device location, device performance, etc. The communication mechanism refers to the mechanism or protocol that the data center can support when conducting network communication. It can also be understood as the communication capability of the data center, such as BGP (Border Gateway Protocol), IPSEC (Internet Protocol Security), VXLAN (Virtual Extensible Local Area Network), NAT (Network Address Translation), etc. The communication mechanism information can refer to the basic information of the communication mechanism, such as usage scenarios, types, usage rules, etc.

[0035] Exemplarily, a user initiates an instruction to instruct at least two data centers to interconnect. When the general control center of the SDN network detects the instruction, it can send an information exchange instruction to the SDN controllers of these data centers to instruct the SDN controllers to obtain and exchange information. After receiving the information exchange instruction, each SDN controller can first obtain the network equipment information and communication mechanism information of the corresponding data center, and exchange this information with the SDN controller that needs to be interconnected, so that each interconnected data center can have the relevant information of each other. In one example, the SDN controller can exchange information by registering the network address of the other data center.

[0036] For example, taking the interconnection between data center 1 and data center 2 as an example, data center 1 is deployed with SDN controller 1, whose network address is IP1, and data center 2 is deployed with SDN controller 2, whose network address is IP2. The general control center sends information exchange instructions to both SDN controller 1 and SDN controller 2. SDN controller 1 and SDN controller 2 register each other's network addresses, that is, IP2 is distributed on SDN controller 1, and IP1 is configured on SDN controller 2. In this way, SDN controller 1 can obtain the network equipment information and communication mechanism information of data center 2, and SDN controller 2 can obtain the network equipment information and communication mechanism information of data center 1, so as to realize information exchange between the two parties and facilitate the subsequent formulation of the interconnection plan.

[0037] Step S204: determining at least one candidate interconnection scheme between data centers based on the information of each network device and the information of each communication mechanism.

[0038] The candidate interconnection scheme refers to multiple candidate schemes for interconnecting data centers. It should be noted that the interconnection scheme includes network devices for interconnecting data centers and the communication mechanism used for interconnection. Of course, in actual applications, other information such as interconnection duration, interconnection frequency, etc. can be configured in the interconnection scheme according to actual needs.

[0039] For example, after completing the information exchange, the SDN controllers of each data center can negotiate the interconnection plan based on the information of each network device and each communication mechanism. The interconnection plan negotiation can be understood as the process of each SDN controller negotiating an interconnection plan acceptable to each party through exchanging information. The candidate interconnection plan is the interconnection plan agreed upon by each SDN controller. It can be understood that the candidate interconnection plan is the interconnection plan generated from the perspective of each data center.

[0040] In one example, when the network device information and / or communication mechanism information of one party is updated, each candidate interconnection scheme will also be updated synchronously, that is, each SDN controller will re-exchange information and re-negotiate the interconnection scheme.

[0041] Step S206, obtaining the interconnection requirement indicated by the interconnection instruction, and selecting a target interconnection solution that matches the interconnection requirement from each candidate interconnection solution.

[0042] The interconnection requirements refer to the requirements for interconnection between data centers, such as backup link requirements, security, encryption, low cost, tenant isolation, etc. The target interconnection solution includes target network devices for interconnection among network devices, and target communication mechanisms for interconnection among communication mechanisms. What is interconnected is a network device under each data center.

[0043] Exemplarily, when the user initiates the interconnection instruction, the interconnection demand can be sent to the general control center simultaneously. It should be noted that this interconnection demand may include the interconnection demand of each data center side, that is, each data center may have a corresponding interconnection demand. Based on the interconnection demand, the general control center can screen out the target interconnection solution that matches the interconnection demand from the multiple candidate interconnection solutions negotiated by each SDN controller, and send it to each SDN controller. Of course, the general control center can also send the interconnection demand to each SDN controller, and each SDN controller will continue to select the optimal target interconnection solution directly based on the interconnection demand after negotiating multiple candidate interconnection solutions. The target interconnection solution is an interconnection solution that is agreed upon between the SDN controllers and meets the user's needs. It can be understood that the target interconnection solution is an interconnection solution selected from the perspective of interconnection demand or user demand. In one example, when the interconnection demand is updated, the general control center will also re-screen the target interconnection solution.

[0044] Step S208, controlling each target network device to interconnect according to the target communication mechanism, and obtaining the interconnection result between each data center.

[0045] The interconnection of data centers can essentially be the interconnection of network devices under the data center. Therefore, when the interconnection between the network devices is completed, the data centers are naturally interconnected. The interconnection result can be used to characterize whether the interconnection between the data centers is successful, which can include successful interconnection and interconnection failure. Of course, in actual applications, the interconnection result can also include other information such as interconnection duration, interconnection failure reasons, etc.

[0046] Exemplarily, after acquiring the target interconnection plan, each SDN controller may send the target interconnection plan to each target network device indicated in the target interconnection plan, so that each target network device can interconnect according to the target communication mechanism indicated in the target interconnection plan, thereby realizing the interconnection of each data center.

[0047] In this embodiment, the general control center responds to the interconnection instruction between multiple data centers, and first obtains the network device information deployed in each data center and the communication mechanism information of each data center. Based on the network device information and the communication mechanism information, at least one candidate interconnection scheme between each data center is generated. The interconnection scheme is generated from the perspective of network devices and communication mechanisms, which can effectively improve the accuracy and reliability of the interconnection scheme and provide data support for subsequent interconnection operations. Then, the interconnection demand indicated by the interconnection instruction is obtained to screen out the target interconnection scheme that matches the interconnection demand from each candidate interconnection scheme, that is, the best interconnection scheme. Finally, by controlling each target network device in the target interconnection scheme, the interconnection is carried out according to the target communication mechanism in the target interconnection scheme, thereby realizing the interconnection between each data center. Therefore, this embodiment generates an accurate and reliable interconnection scheme based on the network device information and the communication mechanism information, and selects an optimal interconnection scheme according to actual needs, which not only improves the reliability of data center interconnection, but also avoids the phenomenon of poor interconnection effect or even failure, thereby improving the efficiency of data center interconnection.

[0048] In an exemplary embodiment, as shown in FIG3 , based on the information of each network device and the information of each communication mechanism, determining at least one candidate interconnection scheme between each data center includes:

[0049] Step S302: Based on the information of each network device, network devices of different data centers are combined to obtain each interconnected device combination.

[0050] The interconnected device combination refers to the combination between various network devices. Take data center 1 and data center 2 as an example. For ease of understanding, the network devices and communication mechanisms are represented in the form of data sets. Assuming that data center 1 has network devices {A1, A2} and data center 2 has network devices {B1, B2}, then the interconnected device combinations are {A1, B1}, {A1, B2}, {A2, B1}, {A2, B2}.

[0051] For example, after completing the information exchange, each SDN controller can select network devices that can be combined from multiple network devices based on the information of each network device. The basis for combining can be that the network device information is normal, that is, there is no abnormal data. Then, each network device is combined to obtain multiple interconnected device combinations.

[0052] Step S304: based on the information of each communication mechanism, at least one interconnection mechanism common to each data center is selected from each communication mechanism.

[0053] The interconnection mechanism refers to the communication mechanism shared by all data centers. For example, if data center 1 supports the communication mechanism {BGP, IPSEC, VXLAN} and data center 2 supports the communication mechanism {IPSEC, NAT}, then the interconnection mechanism is {IPSEC}. If data center 1 supports the communication mechanism {BGP, IPSEC, VXLAN, NAT} and data center 2 supports the communication mechanism {IPSEC, NAT}, then the interconnection mechanism is {IPSEC}, {NAT}. There can be multiple interconnection mechanisms.

[0054] For example, similar to the network device combination, after completing the information exchange, each SDN controller can also select the communication mechanism shared by each data center from the communication mechanisms according to the information of each communication mechanism as the interconnection mechanism. In addition to the consistent name of the communication mechanism, the communication mechanism information of the shared communication mechanism also needs to be consistent. The obtained interconnection mechanism can be further combined with each interconnection device combination. It should be noted that the network device combination and communication mechanism screening do not distinguish the order of execution, and can be executed in the set order or simultaneously.

[0055] Step S306: The interconnection device combinations and the interconnection mechanisms together constitute candidate interconnection solutions between the data centers.

[0056] Exemplarily, after obtaining each interconnected device combination and the interconnection mechanism shared by each data center, each SDN controller can combine each interconnected device combination and the interconnection mechanism again to obtain a candidate interconnection solution.

[0057] For example, the interconnection device combinations are {A1, B1}, {A1, B2}, {A2, B1}, {A2, B2}, and the interconnection mechanisms are {IPSEC}, {NAT}, then the candidate interconnection schemes can be: <{A1, B1}, {IPSEC}>, <{A1, B1}, {NAT}>, <{A1, B2}, {IPSEC}>, <{A1, B2}, {NAT}>, <{A2, B1}, {IPSEC}>, <{A2, B1}, {NAT}>, <{A2, B2}, {{A2, B2}}>, <{A2, B2}, {NAT}>.

[0058] In this embodiment, by combining various network devices to obtain an interconnection device combination, and screening out a communication mechanism common to each data center as an interconnection mechanism, multiple candidate interconnection schemes are generated based on the interconnection device combination and the interconnection mechanism, thereby improving the accuracy and reliability of the candidate interconnection schemes, and further improving the reliability of the entire data center interconnection.

[0059] In an exemplary embodiment, the data center interconnection method further includes: scoring each candidate interconnection scheme based on multiple evaluation indicators to obtain a first indicator score of each candidate interconnection scheme under each evaluation indicator.

[0060] The evaluation index may be a predefined index for scoring the candidate interconnection schemes, such as location, performance, capacity, etc. The first index score may refer to the score of the candidate interconnection scheme under each evaluation index, which may be a specific value.

[0061] For example, taking the candidate interconnection schemes <{A1, B1}, {IPSEC}> and <{A1, B2}, {NAT}> as examples, assuming that the candidate interconnection scheme <{A1, B1}, {IPSEC}> scores 100 points under the security index, indicating that the scheme has a high level of security and can ensure the security of data center interconnection. The score under the performance index is 48 points, indicating that the interconnection performance under this scheme is at a medium-low level. Assuming that the candidate interconnection scheme <{A1, B2}, {NAT}> also scores 100 points under the security index, the security level is also very high. The score under the performance index is 32 points. Compared with the previous candidate interconnection scheme, the interconnection performance of this scheme is lower. When determining the target interconnection scheme in the future, the previous candidate interconnection scheme can be given priority.

[0062] Exemplarily, after each SDN controller negotiates multiple candidate interconnection schemes, the general control center can score each candidate interconnection scheme according to pre-defined evaluation indicators, and calculate the indicator score of each candidate interconnection scheme under each evaluation indicator, so as to subsequently screen out the target interconnection scheme based on the indicator score and improve the accuracy of the target interconnection scheme.

[0063] In an exemplary embodiment, as shown in FIG4 , selecting a target interconnection solution that matches the interconnection requirement from each candidate interconnection solution includes:

[0064] Step S402: determining a first target indicator with the highest priority among the evaluation indicators based on the interconnection requirements.

[0065] Among them, priority refers to the priority of the evaluation indicator, or the priority of determining the target interconnection solution. The first target indicator is the evaluation indicator with the highest priority. For example, assuming that the interconnection requirements are high security and high performance. Then the highest priority among the evaluation indicators is the security indicator, followed by the performance indicator.

[0066] Exemplarily, the general control center determines the first target indicator with the highest priority among various evaluation indicators according to the interconnection demand, which serves as the main basis for subsequently determining the target interconnection solution.

[0067] Step S404: Filter out the first target score of each candidate interconnection solution under the first target indicator from the first indicator scores.

[0068] The first target score refers to the score of the candidate interconnection solution under the first target indicator.

[0069] Exemplarily, after the general control center determines the first target indicator with the highest priority, it can filter out the indicator scores of each candidate interconnection solution under the first target indicator from the first indicator scores calculated previously.

[0070] Step S406: taking the candidate interconnection solution with the highest first target score as the target interconnection solution.

[0071] Exemplarily, the general control center selects the one with the highest score from each first target score, and the corresponding candidate interconnection scheme is the target interconnection scheme. Of course, if the first target scores of all candidate interconnection schemes are the same, for example, when the scores of candidate interconnection schemes <{A1, B1}, {IPSEC}> and <{A1, B2}, {NAT}> under the security index are both 100, then the second priority, that is, the performance index, needs to be considered, and the candidate interconnection scheme with the highest performance index score is used as the target interconnection scheme, that is, <{A1, B1}, {IPSEC}> is the target interconnection scheme.

[0072] In this embodiment, by calculating the score of each candidate interconnection scheme under each evaluation indicator, the optimal target interconnection scheme is screened out according to the score, thereby improving the accuracy and reliability of the target interconnection scheme, thereby improving the reliability and accuracy of the entire data center interconnection.

[0073] In an exemplary embodiment, as shown in FIG5 , the data center interconnection method further includes:

[0074] Step S502: when the interconnection requirement includes a backup link requirement, the target interconnection solution is eliminated from each candidate interconnection solution to obtain a plurality of remaining interconnection solutions.

[0075] The backup link requirement refers to the need for a backup link in the interconnection, that is, a backup interconnection solution needs to be selected as a backup link. The remaining interconnection solutions refer to the candidate interconnection solutions after the target interconnection solution is eliminated from the candidate interconnection solutions.

[0076] For example, when there is a backup link requirement in the interconnection requirement, it means that the general control center also needs to select a backup interconnection solution as a backup link. Therefore, after determining the target interconnection solution, the general control center uses the target interconnection solution as the main link. Then, the target interconnection solution is eliminated from each candidate interconnection solution to obtain multiple remaining interconnection solutions, that is, the target interconnection solution is not within the screening range of the backup interconnection solution.

[0077] Step S504, respectively obtain the second indicator score of each remaining interconnection solution under each evaluation indicator.

[0078] The second indicator score refers to the score of the remaining interconnection schemes under the evaluation indicator. It is understandable that when selecting the backup interconnection schemes, in order to ensure the accuracy of the backup interconnection schemes, the remaining interconnection schemes also need to be re-scored. This process is the same as the scoring process of the target interconnection scheme, and will not be repeated here.

[0079] Exemplarily, the general control center re-scores each remaining interconnection solution and calculates an indicator score of each remaining interconnection solution under each evaluation indicator.

[0080] Step S506: Determine a second target indicator with the highest priority among the evaluation indicators based on the backup link requirement.

[0081] The backup link requirement refers to the requirement for the backup link, that is, the requirement for the backup interconnection solution, which is the same as the interconnection requirement of the target interconnection solution, and the backup interconnection solution may also have corresponding requirements. The second target indicator refers to the highest priority evaluation indicator for the backup interconnection solution.

[0082] Exemplarily, the general control center determines the second target indicator with the highest priority among various evaluation indicators according to the backup link requirements, which serves as the main basis for subsequently determining the backup interconnection solution.

[0083] Step S508: Filter out the second target score of each remaining interconnection solution under the second target indicator from the second indicator scores.

[0084] The second target score refers to the score of the remaining interconnection solutions under the second target indicator.

[0085] Exemplarily, after the general control center determines the second target indicator with the highest priority, it can filter out the indicator scores of each remaining interconnection scheme under the second target indicator from the second indicator scores calculated previously.

[0086] Step S510: taking the remaining interconnection scheme with the highest second target score as a backup interconnection scheme matching the backup link requirement.

[0087] Exemplarily, the general control center selects the one with the highest score from among the second target scores, and the remaining interconnection schemes corresponding to the one are the backup interconnection schemes.

[0088] In this embodiment, by calculating the scores of the remaining interconnection schemes except the target interconnection scheme under each evaluation indicator, the optimal backup interconnection scheme is screened out according to the scores, thereby improving the accuracy and reliability of the backup interconnection schemes, and further improving the reliability and accuracy of the entire data center interconnection.

[0089] In an exemplary embodiment, as shown in FIG6 , each candidate interconnection scheme is scored based on multiple evaluation indicators to obtain a first indicator score of each candidate interconnection scheme under each evaluation indicator, including:

[0090] Step S602 , matching scoring methods for each evaluation indicator is performed to obtain scoring methods that match each evaluation indicator.

[0091] Here, scoring method matching refers to the process of matching the best scoring method for each evaluation indicator. It is understandable that for each evaluation indicator, there may be multiple different scoring methods.

[0092] For example, when scoring each candidate interconnection solution, the general control center may first match the scoring method for each evaluation indicator to match the optimal scoring method, thereby improving the efficiency and accuracy of the scoring.

[0093] For example, taking the performance index as an example, the score of the performance index can be calculated by capacity. For example, assuming that the capacity of network device A1 is 80% and the capacity of network device B1 is 60%, then the score of the candidate interconnection scheme <{A1, B1}, {IPSEC}> under the performance index can be (80%*60%) / 100=48 points, which is a scoring method. It can also be based on the communication rate between network device A1 and network device B1 to evaluate the performance, which is also a scoring method. The capacity index can be directly determined according to the capacity size. The larger the capacity, the higher the score of the capacity index, and vice versa. The location index can be scored based on the location distance between each network device. The closer the distance is, the higher the location score is. Of course, in actual applications, other evaluation indicators and corresponding scoring methods can be defined according to actual conditions, and this embodiment does not limit this.

[0094] Step S604: score each candidate interconnection solution according to each scoring method to obtain a first indicator score of each candidate interconnection solution under each evaluation indicator.

[0095] Exemplarily, after the general control center matches the optimal scoring method corresponding to each evaluation indicator, each candidate interconnection scheme can be scored according to these scoring methods to obtain the first indicator score of each candidate interconnection scheme under each evaluation indicator.

[0096] In this embodiment, the most appropriate scoring method is screened out through scoring method matching, thereby improving the accuracy of indicator scoring, and further improving the accuracy of the target interconnection solution.

[0097] In an exemplary embodiment, as shown in FIG. 7 , in response to an interconnection instruction between multiple data centers, network device information of each network device deployed in each data center and communication mechanism information of each communication mechanism of each data center when performing network communication are respectively obtained, including:

[0098] Step S702, in response to the interconnection instruction between the multiple data centers, a performance test is performed on each data center to obtain a performance test result of each data center.

[0099] The performance test results may be results used to characterize the performance of a data center, such as the stability, response speed, and security of the data center.

[0100] For example, in order to further ensure the reliability of data center interconnection, before the data center interconnection is carried out, the main control center may send a performance test instruction to the SDN controller of each data center to instruct the SDN controller to perform a performance test on the data center to obtain the performance test results of the data center.

[0101] Step S704, when each performance test result meets the interconnection condition, obtain the network device information of each network device deployed in each data center and the communication mechanism information of each communication mechanism of each data center when performing network communication.

[0102] The interconnection conditions may refer to the preconditions pre-defined for data center interconnection, such as each data center needs to have a certain stability, fast response speed, high security, etc.

[0103] For example, after receiving the performance test results of the data center fed back by each SDN controller, the general control center can determine whether these performance test results meet the predefined interconnection conditions. If they meet, an information exchange instruction is sent to the SDN controller to instruct each SDN controller to obtain and exchange information. If not, the general control center can reject the data center interconnection request.

[0104] In this embodiment, performance testing is performed on each data center that needs to be interconnected to ensure that each data center meets the interconnection conditions, thereby improving the reliability of the data center interconnection.

[0105] In a specific embodiment, the architecture diagram of data center interconnection is shown in FIG8 , which includes data center 1 and data center 2. Data center 1 includes SDN controller 1, and data center 2 includes SDN controller 2. Network device information and communication mechanism information are exchanged between SDN controller 1 and SDN controller 2. Finally, an optimal target interconnection scheme is obtained and sent to the corresponding network device 1 and network device 2. Network device 1 and network device 2 are interconnected according to the target communication mechanism in the target interconnection scheme, thereby realizing the interconnection between data center 1 and data center 2.

[0106] FIG9 shows a flow chart of data center interconnection. In response to the interconnection instruction between data center 1 and data center 2, the SDN controllers of both parties register each other's network addresses to exchange network device information and communication mechanism information. The SDN controllers of both parties negotiate based on this information to obtain multiple candidate interconnection schemes. According to the interconnection requirements and multiple evaluation indicators, each candidate interconnection scheme is scored, and the target interconnection scheme that matches the interconnection requirements is screened out from each candidate interconnection scheme. The target interconnection scheme is sent to network device 1 and network device 2, instructing network device 1 and network device 2 to interconnect according to the target communication mechanism, thereby completing the interconnection between data center 1 and data center 2.

[0107] In this embodiment, the general control center responds to the interconnection instruction between multiple data centers, and first obtains the network device information deployed in each data center and the communication mechanism information of each data center. Based on the network device information and the communication mechanism information, at least one candidate interconnection scheme between each data center is generated. The interconnection scheme is generated from the perspective of network devices and communication mechanisms, which can effectively improve the accuracy and reliability of the interconnection scheme and provide data support for subsequent interconnection operations. Then, the interconnection demand indicated by the interconnection instruction is obtained to screen out the target interconnection scheme that matches the interconnection demand from each candidate interconnection scheme, that is, the best interconnection scheme. Finally, by controlling each target network device in the target interconnection scheme, the interconnection is carried out according to the target communication mechanism in the target interconnection scheme, thereby realizing the interconnection between each data center. Therefore, this embodiment generates an accurate and reliable interconnection scheme based on the network device information and the communication mechanism information, and selects an optimal interconnection scheme according to actual needs, which not only improves the reliability of data center interconnection, but also avoids the phenomenon of poor interconnection effect or even failure, thereby improving the efficiency of data center interconnection.
