Description

Technical Field

[0001] The present invention relates to the technical field of data interaction, and in particular to a data interaction method between clusters, a data interaction device between clusters, an electronic device and a computer-readable storage medium. Background Art

[0002] The current cluster network controller architecture exists in a single cluster in a multi-AZ (Availability Zones) scenario, and the entire AZ cannot be migrated to other clusters.

[0003] like Figure 1 As shown in the figure, multiple AZs (az-1, az-2, ..., az-n) coexist in one hostgroup (single cluster instance), and all VPCs (Virtual Private Clouds) forward traffic to IDCs (Internet Data Centers) through Controller Hostgroup1 (based on BGP and DP (Data Plane)). The ratio between controllers (Controller3 and Controller4) and data planes DP (Data Plane) (Data Plane1 and Data Plane2) is 1:1, and DP uses a programmable switch. When VPC reaches 10W, the bfswith (Breadth-First Search) bottleneck will be reached.

[0004] against Figure 2 When the number of VPCs reaches a certain threshold, two problems will occur. The first problem is that the controller reconciliation is slow. The second problem is that the DP will encounter OOM (Out of Memory) due to the large amount of data, which will directly cause the current hostgroup to crash. Since multiple clusters cannot automatically learn and calculate loads, the cluster will become unavailable as a whole. At the same time, the clusters cannot forward traffic to each other, resulting in multiple hostgroups being unable to interact normally (az-1, az-2, ..., az-n are disconnected).

[0005] The problem with current technology is that when DP reaches the bottleneck of 100,000, dynamic configuration is performed to switch clusters, such as Figure 3However, when the cluster switching is not completed, VPC Peering, VPN (Virtual Private Network), DC (Data Center) and other services will be disconnected, which will directly cause the traffic to be sent to the hostgroup and cannot be identified as its own traffic, resulting in data packet discard, which directly affects customer services.

[0056] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Reference Figure 4 , shows a flow chart of the steps of a data interaction method between clusters according to an embodiment of the present invention; wherein the clusters may include a first cluster and other clusters. The first cluster may refer to any cluster among all clusters, and the other clusters may refer to other clusters among all clusters except the first cluster.

[0058] like Figure 4 As shown, the data interaction method between clusters may include the following steps:

[0059] Step 401: The first cluster receives sharding information, where the sharding information is used to indicate the cluster to which the traffic data belongs.

[0060] Taking the first cluster as an example, the controller may first send sharding information to the first cluster. The sharding information may be generated by the controller and used to indicate the cluster to which the traffic data belongs.

[0061] Specifically, the controller can set the cluster to which each flow data belongs based on strategies such as load balancing; when flow data needs to be transmitted between the virtual private cloud and the Internet data center, the data can be routed through the cluster to which the flow data belongs.

[0062] Data routing refers to the process of transmitting data packets from the source address to the destination address in the network. This process usually involves the following key steps:

[0063] Routing table: A routing table is a table used by network devices (such as routers) to determine the transmission path of data packets. It contains the mapping relationship between the destination address and the next hop address.

[0064] Routing Protocol: A routing protocol is a protocol for exchanging routing information between network devices. Common routing protocols include OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol).

[0065] Routing decision: When a data packet arrives at a router, the router will determine the next hop address of the data packet based on the information in the routing table and routing protocol. This process is called routing decision.

[0066] Forwarding: Once the router determines the next hop address of the data packet, it will forward the data packet to the corresponding interface and continue to transmit to the next network device until the data packet reaches the destination address.

[0067] After receiving the shard information, the first cluster may store it locally, so that after receiving the traffic data subsequently, the cluster to which the traffic data belongs may be determined based on the shard information.

[0068] Step 402: After receiving the first traffic data, the first cluster determines whether the cluster to which the first traffic data belongs is the first cluster according to the sharding information.

[0069] In actual applications, after receiving first traffic data that needs to be routed, the first cluster may first query the shard information.

[0070] Specifically, the first cluster may first query the shard information to determine information about the first traffic data in the shard information.

[0071] Then, the first cluster may determine which cluster the first traffic data belongs to based on the information about the first traffic data in the shard information; specifically, it may further determine whether the cluster to which the first traffic data belongs is the first cluster.

[0072] Step 403: When it is determined that the cluster to which the first traffic data belongs is the first cluster, the first cluster routes the first traffic data.

[0073] When it is determined that the cluster to which the first traffic data belongs is the first cluster, the first cluster may normally route the first traffic data.

[0074] Specifically, the first cluster may route the first traffic data based on BGP and DP.

[0075] Exemplarily, the first cluster exchanges routing information with other autonomous systems through BGP. BGP dynamically updates the network topology to ensure that the first cluster can obtain the latest routing information. When the first traffic data arrives at the first cluster, the first cluster makes a routing decision based on the routing information provided by BGP and the configuration of the data plane.

[0076] For example, cluster 1 can select the optimal path to ensure efficient data packet transmission. Once the routing decision is made, the data plane of cluster 1 forwards the data packet to the corresponding interface.

[0077] Programmable switches process and forward data packets according to preset rules and policies to ensure efficient transmission of traffic.

[0078] Step 404: When it is determined that the cluster to which the first traffic data belongs is not the first cluster, the first cluster sends the first traffic data to the cluster to which the first traffic data belongs, so that the cluster to which the first traffic data belongs routes the first traffic data.

[0079] On the other hand, if it is determined that the cluster to which the first traffic data belongs is not the first cluster, the first cluster first determines the cluster to which the first traffic data actually belongs. For the convenience of subsequent description, the cluster to which the first traffic data actually belongs is called the second cluster.

[0080] After determining the second cluster, the first cluster may send the received first traffic data to the second cluster, and then the second cluster routes the first traffic data.

[0081] Specifically, the second cluster may route the first traffic data based on BGP and DP.

[0082] Exemplarily, the second cluster exchanges routing information with other autonomous systems through BGP. BGP dynamically updates the network topology to ensure that the second cluster can obtain the latest routing information. When the first traffic data reaches the second cluster, the second cluster makes a routing decision based on the routing information provided by BGP and the configuration of the data plane.

[0083] For example, the second cluster can select the optimal path to ensure that the data packet can be transmitted efficiently. Once the routing decision is made, the data plane of the second cluster forwards the data packet to the corresponding interface.

[0084] Programmable switches process and forward data packets according to preset rules and policies to ensure efficient transmission of traffic.

[0085] In an embodiment of the present invention, the first cluster receives sharding information, and the sharding information is used to indicate the cluster to which the traffic data belongs; after receiving the first traffic data, the first cluster determines whether the cluster to which the first traffic data belongs is the first cluster based on the sharding information; when it is determined that the cluster to which the first traffic data belongs is the first cluster, the first cluster routes the first traffic data; when it is determined that the cluster to which the first traffic data belongs is not the first cluster, the first cluster sends the first traffic data to the cluster to which the first traffic data belongs, so that the cluster to which the first traffic data belongs routes the first traffic data.

[0086] By using the embodiment of the present invention, it is possible to avoid notifying network elements of other departments to modify VIPs when performing cluster switching, and traffic interruption will not occur.

[0087] Reference Figure 5 , shows a flowchart of another method for data interaction between clusters according to an embodiment of the present invention, which may include the following steps:

[0088] Step 501: The first cluster receives sharding information.

[0089] Taking the first cluster as an example, the controller may first send sharding information to the first cluster. The sharding information may be generated by the controller and used to indicate the cluster to which the traffic data belongs.

[0090] Specifically, the controller can set the cluster to which each flow data belongs based on strategies such as load balancing; when flow data needs to be transmitted between the virtual private cloud and the Internet data center, the data can be routed through the cluster to which the flow data belongs.

[0091] Step 502, the cluster is connected to the cluster controller; the cluster controller is used to set the sharding information of each flow data according to the data layering plane to which each flow data belongs, and the cluster includes the data layering plane; after receiving the first flow data, the first cluster determines whether the data layering plane to which the first flow data belongs belongs to the first cluster according to the sharding information.

[0092] In some feasible embodiments, the first cluster and other clusters may be connected to a cluster controller, and the cluster controller may be used to set sharding information of each flow data according to the data layer plane to which each flow data belongs.

[0093] In actual applications, in the network architecture, the cluster is not only responsible for processing and routing the initial or main traffic data in the network, but also can include the data layering plane; therefore, the first cluster can determine the data layering plane to which the received traffic data belongs based on the sharding information, and then determine the cluster to which the traffic data belongs.

[0094] Specifically, after receiving the first traffic data, the first cluster may first query the shard information.

[0095] Specifically, the first cluster may first query the shard information to determine information about the first traffic data in the shard information.

[0096] Then, the first cluster may determine the data layer plane to which the first traffic data belongs based on the information about the first traffic data in the shard information.

[0097] Next, the first cluster may determine whether the data layering plane to which the first traffic data belongs belongs to the first cluster.

[0098] In one embodiment of the present invention, the cluster controller is used to set the data layer plane to which each flow data belongs based on a preset load balancing strategy.

[0099] In some feasible embodiments, in order to ensure load balancing, the cluster controller can set the data layering plane for each traffic data based on a preset load balancing strategy to avoid different burdens on the clusters, which may cause some clusters to be overloaded or underloaded, thereby affecting the utilization of the entire cluster.

[0100] Exemplarily, the cluster controller may allocate a data layering plane to each flow data based on the load, performance, etc. of each cluster.

[0101] In one embodiment of the present invention, the cluster controller is used to slice the virtual private cloud corresponding to each flow data in sequence; and set the data layering plane corresponding to each slice of flow data.

[0102] In some feasible embodiments, the cluster controller may directly slice the virtual private cloud corresponding to each flow data in sequence to obtain multiple slices.

[0103] Then, the data layering plane to which each flow data belongs can be set for the flow data corresponding to each shard.

[0104] In one embodiment of the present invention, the cluster controller is used to divide the virtual network identifier of each virtual private cloud according to the classless inter-domain routing of the Internet protocol to obtain multiple slices.

[0105] In some feasible embodiments, the cluster controller may shard all virtual private clouds; the sharding logic may be:

[0106] The VNI (Virtual Network Identifier) ​​of the virtual private cloud is divided according to the CIDR (Classless Inter-Domain Routing) of the IP (Internet Protocol) to obtain different shards.

[0107] In one embodiment of the present invention, the cluster controller is further configured to partition a shard when traffic data belonging to different data layer planes exists in the shard.

[0108] In some feasible embodiments, during sharding, traffic data belonging to different data layering planes may also be divided into one shard.

[0109] At this time, the cluster controller may also partition a shard when traffic data belonging to different data layering planes exists in the shard.

[0110] Step 503: When it is determined that the cluster to which the first traffic data belongs is the first cluster, the first cluster routes the first traffic data.

[0111] When it is determined that the cluster to which the data layer plane to which the first traffic data belongs belongs is the first cluster, the first cluster may normally route the first traffic data.

[0112] Specifically, the first cluster may route the first traffic data based on BGP and DP.

[0113] Exemplarily, the first cluster exchanges routing information with other autonomous systems through BGP. BGP dynamically updates the network topology to ensure that the first cluster can obtain the latest routing information. When the first traffic data arrives at the first cluster, the first cluster makes a routing decision based on the routing information provided by BGP and the configuration of the data plane.

[0114] For example, cluster 1 can select the optimal path to ensure efficient data packet transmission. Once the routing decision is made, the data plane of cluster 1 forwards the data packet to the corresponding interface.

[0115] Programmable switches process and forward data packets according to preset rules and policies to ensure efficient transmission of traffic.

[0116] Step 504: When it is determined that the cluster to which the first traffic data belongs is not the first cluster, the first cluster sends the first traffic data to the cluster to which the first traffic data belongs, so that the cluster to which the first traffic data belongs routes the first traffic data.

[0117] On the other hand, if it is determined that the cluster to which the first traffic data belongs is not the first cluster, the first cluster first determines the cluster to which the first traffic data actually belongs. For the convenience of subsequent description, the cluster to which the first traffic data actually belongs is called the second cluster.

[0118] After determining the second cluster, the first cluster may send the received first traffic data to the second cluster, and then the second cluster routes the first traffic data.

[0119] Specifically, the second cluster may route the first traffic data based on BGP and DP.

[0120] Exemplarily, the second cluster exchanges routing information with other autonomous systems through BGP. BGP dynamically updates the network topology to ensure that the second cluster can obtain the latest routing information. When the first traffic data reaches the second cluster, the second cluster makes a routing decision based on the routing information provided by BGP and the configuration of the data plane.

[0121] For example, the second cluster can select the optimal path to ensure that the data packet can be transmitted efficiently. Once the routing decision is made, the data plane of the second cluster forwards the data packet to the corresponding interface.

[0122] Programmable switches process and forward data packets according to preset rules and policies to ensure efficient transmission of traffic.

[0123] Step 505: Receive second traffic data; the cluster to which the second traffic data belongs has been deleted.

[0124] In some feasible embodiments, a cluster may be removed. In this case, the traffic data set for the cluster may not be able to continue to modify the cluster routing. To address this problem, the method of the embodiment of the present invention can also perform service switching quickly and losslessly.

[0125] Specifically, the cluster to be deleted is called the third cluster, and the traffic data corresponding to the third cluster is called the second traffic data.

[0126] When transmitting the second traffic data, when it is detected that the third cluster has been deleted, the controller may set the second traffic data to be routed by the first cluster based on a preset load balancing strategy.

[0127] Thus, when transmitting the second traffic data, the DCGW (Data Center Gateway) can transmit the second traffic data to the first cluster.

[0128] Step 506: route the second traffic data.

[0129] After receiving the second traffic data, the first cluster may forward the second traffic data; specifically:

[0130] The first cluster can exchange routing information with other autonomous systems through BGP. BGP dynamically updates the network topology to ensure that the first cluster can obtain the latest routing information. When the first traffic data reaches the first cluster, the first cluster makes a routing decision based on the routing information provided by BGP and the configuration of the data plane.

[0131] For example, Figure 6 As shown, when configuring the cluster controller, you can not only configure it to ControllerHostgroup1 (including Controller3 and Controller4), but also to ControllerHostgroup2 (including Controller1 and Controller2). When both clusters have this data, load balancing is basically achieved.

[0132] Perform sharding on the VPC configuration information (obtain shard 1 and shard 2), sort the VPCs in order and divide the VPCs into shards according to the CIDR of the IP, mark the ControllerHostgroup where the data of the current shard is located, and download the sharding information. When the traffic switching is not completed or involves interaction with other gateways and the VIP cannot be changed, the ControllerHostgroup where the current VPC is located can be queried, and DP forwards the traffic to the corresponding ControllerHostgroup.

[0133] like Figure 7 As shown in the figure, the current shard information (Shard 1 (VPC1-DP1, VPC2-DP1), Shard 2 (VPC3-DP1, VPC4-DP1), Shard 3 (VPC5-DP1, VPC6-DP1), Shard 4 (VPC7-DP1, VPC8-DP1)) is all in DP1, so all traffic data passes through DP1 of Controller Hostgroup1, not DP2 of Controller Hostgroup2.

[0134] like Figure 8 As shown, Figure 7 As shown, DP1 switches after the load reaches the threshold. Even if the traffic data in shard 3 returns to DP1 from other external network elements, DP1 can still forward traffic according to the Controller Hostgroup where the current VPC is located, preventing traffic interruption or service interruption.

[0135] like Fig. 9 As shown, first, all VPCs are sharded. The logic of sharding is to divide the VNI of the created VPC into different shards according to the CIDR of the IP, and obtain shard 1 (VPC1-DP1, VPC2-DP1), shard 2 (VPC3-DP1, VPC4-DP1), shard 3 (VPC5-DP1, VPC6-DP1), shard 4 (VPC7-DP1, VPC8-DP1). Shard 1, shard 2, shard 3 and shard 4 all correspond to Controller Hostgroup1 (hg1).

[0136] like Fig.10 As shown, VPC1, VPC2 and VPC5 are then switched to another (Controller Hostgroup2) hg2. At this time, the traffic of shard 1 needs to be switched to hg2, and shard 3 needs to be split into 2 shards (shard 3-1 and shard 3-2) to complete the data configuration.

[0137] like Fig.11 As shown, after the switching is completed, even if other network elements record the VIP of hg1, it will not affect the forwarding. When hg1 finds that the fragmentation information is in hg2, hg1 will forward the traffic of the current VNI to hg2. When hg2 detects it as its own traffic, it enters its own DP for normal traffic forwarding.

[0138] For example, in the case of dedicated line access to cloud resources, the normal business flow is IDC→DCGW (Data Center Gateway)→VPCGW (Virtual Private Cloud Gateway) (hg1-VPCGW, hg2-VPCGW)→VM (Virtual Machine) (VPC-vm1, VPC-vm2). In this process, if DCGW needs to switch hg, it needs to actively switch. Because DCGW records the VIP of hg1 during active switching, it cannot perceive the switch after the switch is completed, or the switch will be disconnected. On this basis, if sharding is used, even if DCGW traffic is still sent to hg1-VPCGW, hg1-VPCGW can forward the traffic to hg2-VPCGW based on the sharding information to achieve uninterrupted traffic forwarding.

[0139] like Fig.12 As shown in the figure, in the actual deployment process, the VNIs of all VPCs should be sharded. After the sharding is completed, when the traffic is switched, the DCGW sends it to the corresponding hg according to the record; then, the sharding information is queried according to the VNI to perceive whether the current traffic should be processed by the hg to which it belongs, and the corresponding hg is found to forward different traffic.

[0140] In an embodiment of the present invention, the first cluster receives sharding information; the cluster is connected to a cluster controller; the cluster controller is used to set the sharding information of each flow data according to the data layer plane to which each flow data belongs, and the cluster includes a data layer plane; after receiving the first flow data, the first cluster determines whether the data layer plane to which the first flow data belongs belongs to the first cluster according to the sharding information; when it is determined that the cluster to which the first flow data belongs is the first cluster, the first cluster routes the first flow data; when it is determined that the cluster to which the first flow data belongs is not the first cluster, the first cluster sends the first flow data to the cluster to which the first flow data belongs, so that the cluster to which the first flow data belongs routes the first flow data; receives the second flow data; the cluster to which the second flow data belongs has been deleted; and routes the second flow data. Through the embodiment of the present invention, when an irreversible fault occurs in the cluster, service switching can be performed quickly and losslessly; and the shortest millisecond-level jitter is supported, which greatly shortens the time for customer flow switching and reduces the scope of fault impact.

[0141] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0142] Reference Fig.13 , shows a schematic structural diagram of a data interaction device between clusters according to an embodiment of the present invention, where the clusters include a first cluster and other clusters.

[0143] like Fig.13 As shown, the device may include the following modules:

[0144] A receiving module 1301 is used to receive sharding information, where the sharding information is used to indicate the cluster to which the traffic data belongs;
