[0026] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the embodiments of the present application are further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] In order to facilitate understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the embodiments of the present application will be described below.

[0028] Currently, the connection between two cloud devices is typically achieved through VPC routing. Cloud devices can include network elements (NEs) such as routers, load balancers, NAT (Network Address Translation), and firewalls. VPC-based NEs are typically implemented using Elastic Compute Service (ECS), also known as a cloud server. ECS can be understood as a virtual machine that runs on a physical machine. In practice, the connection between cloud devices is essentially the communication between ECSs.

[0029] like Figure 1As shown, a diagram illustrating an example scenario of the prior art is shown. Network element 1 provides the ability for devices in VPC1 and VPC2 to communicate with private networks outside the cloud, forming a transit router (TR). Network element 1 belongs to Service VPC1. Network element 2 can be a router used by a third-party SDWAN (Software Defined Wide Area Network) vendor for multi-cloud interconnection. Network element 2 belongs to Service VPC2. When data packets from VPC1 and VPC2 need to be sent to the external network, network element 1 can send the data packets to network element 2 and then send them to the external network. When network element 1 and network element 2 communicate, VPC routing needs to be configured. For example, the egress routing table of network element 1 is: 192.168.100.0 / 24peering tunnel, and the ingress routing table of network element 1 is: 192.168.1.0 / 24VPC1, 192.168.2.0 / 24VPC2. The egress routing table of NE 2 is: 192.168.100.0 / 24extunnel, and the ingress routing table of NE 2 is: 192.168.1.0 / 24TR, 192.168.2.0 / 24TR.

[0030] The peering tunnel between NE 1 and NE 2 is established based on the VPC network. The VPC network function consists of the QoS (Quality of Service) policy of ENI (Elastic Network Interfaces), the security group ACL (Access Control List), and the VPC routing (TR). Figure 2 As shown in FIG, an example diagram of an implementation of the prior art is shown. Figure 1 In this scenario, at the implementation level, NE 1 is implemented by ECS1, which runs on physical machine 1, and NE 2 is implemented by ECS2, which runs on physical machine 2. When a data packet is sent from NE 1 to NE 2, the peering tunnel traffic passes through vswitch1, the forwarding component that provides VPC functions on physical machine 1 where ECS1 resides.

[0031] Existing implementations require data forwarding based on VPC routing, which is complex to configure. Furthermore, traffic must pass through all functions on the VPC forwarding component, the vswitch. Some of these functions are not essential for data forwarding, resulting in performance overhead and impacting data forwarding performance. Furthermore, tunnel-based data forwarding can introduce significant traffic, necessitating restrictions on single-flow capabilities, which can lead to performance bottlenecks.

[0032] Based on this, the embodiments of the present application provide a cloud network-based data transmission method, device and equipment, and propose a new cloud device interconnection technology, connecting two cloud servers ECS through an elastic network interface pair (ENI pair), and communicating between ECSs based on the address of the elastic network interface in the elastic network interface pair.

[0033] In order to facilitate understanding of the data transmission method of the cloud network provided in the embodiment of the present application, Figure 3 See the example scenario shown. Figure 3 As shown in the figure, this figure is a schematic diagram of an exemplary application scenario provided by an embodiment of the present application.

[0034] Figure 3 The left side shows a diagram of a typical cloud server ECS connection. A typical ECS ENI has only one MAC (Media Access Control) address and belongs to that one ECS. The ENIs of two ECS instances belong to their own subnets and VPCs. Therefore, communication between the two ECS instances requires VPC routing and the full functionality of the VPC.

[0035] Figure 3 On the right is the elastic network interface pair (ENI pair) provided in the embodiment of this application. The ENI pair can be created separately and can be mounted on two ECSs. It has two MAC addresses and does not belong to any subnet or VPC, which greatly simplifies the address planning complexity of user management of ECS interconnection.

[0036] In the embodiment of the present application, ECS interconnection can be extended to all data transmission scenarios between ECSs that are not the source address and destination address of the data packet.

[0037] Those skilled in the art will understand that Figure 3 The framework diagram shown is only an example in which the embodiments of the present application can be implemented. The scope of application of the embodiments of the present application is not limited by any aspect of the framework.

[0038] To facilitate understanding of the embodiments of the present application, a cloud network-based data transmission method provided in the embodiments of the present application is described below with reference to the accompanying drawings.

[0039] See also Figure 4 As shown in FIG, this figure is a flow chart of a data transmission method based on a cloud network provided in an embodiment of the present application, as shown in FIG. Figure 4 As shown, the method may include S401-S403:

[0040] S401: Receive a first data stream transmitted via a first elastic network interface of an elastic network interface pair connected to a first cloud server.

[0041] The elastic network card interface pair is configured with a first elastic network card interface and a second elastic network card interface. The first elastic network card interface is connected to the first cloud server and transmits data stream to the second cloud server through the first elastic network card interface via the second elastic network card interface connected to the second cloud server; the elastic network card interface pair is independently deployed in a subnet in the cloud network.

[0042] In an embodiment of the present application, when the first cloud server and the second cloud server need to be interconnected, the management and control module on the cloud can create an elastic network card interface pair ENI pair, and the ENI pair is configured with two elastic network card interfaces ENI, namely the first elastic network card interface and the second elastic network card interface. Two mac addresses are assigned to the ENI pair, and the ENIs at both ends of the ENI pair have a mac address respectively. The ENI pair is mounted on the first cloud server and the second cloud server, and the first elastic network card interface is used as the ENI used by the first cloud server, and the second elastic network card interface is used as the ENI used by the second cloud server. The first cloud server and the second cloud server each run on a physical machine. The ENI pair is independently deployed in the cloud network and does not belong to the VPC, that is, it provides a non-VPC ENI peer connection method.

[0043] The management and control module can then obtain the address of the first elastic network interface and the address of the second elastic network interface, attach the address of the first elastic network interface and the address of the second elastic network interface to the ENI pair data structure, and send it to the physical machines at both ends.

[0044] Additionally, the ENI pair's IP (Internet Protocol) address can be assigned by the ECS: that is, the first cloud server assigns an IP address to the first elastic network interface, and the second cloud server assigns an IP address to the second elastic network interface. The ECS can use this IP address to specify the ENI pair for communication. In practice, IPv4 can use 169.254 or other non-service-planned / 31 ​​IP addresses, and IPv6 can use commonly used device interconnection addresses.

[0045] The embodiment of the present application describes a cloud network-based data transmission method from the perspective of the physical machine where the first cloud server is located. When the first cloud server sends a first data stream to the second cloud server, the first data stream can be obtained through the first elastic network interface in the ENI pair.

[0046] In a possible implementation, the following may also be included:

[0047] After the elastic network card interface pair is connected to the first cloud server and the second cloud server, the address of the first elastic network card interface and the address of the second elastic network card interface are obtained; and the address of the first elastic network card interface and the address of the second elastic network card interface are saved in the fast channel.

[0048] In actual applications, after the control module issues the addresses of the first and second elastic network interface cards, the physical machine where the first cloud server resides can obtain and save the addresses of the first and second elastic network interface cards. Specifically, the addresses of the first and second elastic network interface cards can be saved in the fast channel of the first forwarding component in the physical machine where the first cloud server resides.

[0049] The address of the first elastic network card interface can be configured as the physical machine address of the physical machine where the first cloud server is located, and the address of the second elastic network card interface can be configured as the physical machine address of the physical machine where the second cloud server is located.

[0050] S402: When it is determined that the first data flow is transmitted via the elastic network interface pair, query the address of the second elastic network interface in the fast channel.

[0051] In practice, the first forwarding component's fastpath stores the ENI pair data structure, which includes the addresses of the first and second elastic network interface cards. When the ENI type determines that the first data flow is sent through the ENI pair, the fastpath is queried for the address of the second elastic network interface card to obtain the physical machine address of the second cloud server.

[0052] S403: Forward the first data flow to the second cloud server based on the address of the second elastic network interface.

[0053] Based on the address of the second elastic network interface, the first data stream is sent to the second cloud server. In actual applications, the first data stream can be sent to a second forwarding component on the physical machine where the second cloud server is located, and the second forwarding component sends the first data stream to the second cloud server.

[0054] In the embodiment of the present application, the elastic network card interface pair is configured with a first elastic network card interface and a second elastic network card interface. The first elastic network card interface is connected to the first cloud server, and the second elastic network card interface is connected to the second cloud server. The elastic network card interface pair is independently deployed in the subnet in the cloud network, that is, it does not belong to any subnet and VPC. When two cloud servers perform data transmission, after receiving the first data stream transmitted via the first elastic network card interface, the address of the second elastic network card interface is queried in the fast channel, and the first data stream is forwarded to the second cloud server based on the address of the second elastic network card interface. Communication based on the address of the second elastic network card interface does not require VPC routing, and the implementation is relatively simple. At the same time, since the elastic network card interface pair does not belong to the VPC, it is not necessary to execute all the functions of the VPC during data transmission, which improves the data transmission performance.

[0055] In one possible implementation, the specific implementation of S403 sending the data packet to the second cloud server on the physical machine corresponding to the physical machine address may include:

[0056] A1: Encapsulate the first data stream. The inner layer of the encapsulated first data stream carries the source address, destination address, source MAC address, and destination MAC address, and the outer layer carries the source physical machine address and destination physical machine address. The source physical machine address is the address of the first elastic network card interface, and the destination physical machine address is the address of the second elastic network card interface. The source MAC address and destination MAC address are the MAC addresses of the elastic network card interface pair.

[0057] The first forwarding component encapsulates the data packet. The inner layer of the encapsulated data packet carries the source address src0, the destination address dst0, the source MAC address, and the destination MAC address. The outer layer carries the address of the first elastic network interface and the address of the second elastic network interface. The source MAC address and the destination MAC address are the MAC addresses assigned to the ENI pair.

[0058] A2: Send the encapsulated first data stream to the physical machine corresponding to the destination physical machine address, so that the physical machine corresponding to the destination physical machine address decapsulates the encapsulated first data stream and sends the decapsulated first data stream to the second cloud server according to the destination MAC address.

[0059] The encapsulated first data stream is sent to the second forwarding component on the physical machine corresponding to the destination physical machine address. The second forwarding component decapsulates the first data stream and sends it to the second cloud server based on the destination MAC address.

[0060] In a possible implementation, the cloud network-based data transmission method provided in the embodiment of the present application may further include: executing a corresponding quality of service policy for the first data stream.

[0061] The first forwarding component and the second forwarding component can also execute corresponding QoS policies, such as limiting the speed of data packets sent through the ENI pair, obtaining the speed limit of the total data packets sent, etc., and thus can skip the security group, VPC route query and other functions of the forwarding component VPC, and only use the required QoS policies to fully improve the communication performance while ensuring the quality of service.

[0062] In one possible implementation, the cloud network-based data transmission method provided in the embodiment of the present application may further include:

[0063] Dynamically update the address of the first or second elastic network interface in the elastic network interface pair as the physical machine connected to the elastic network interface pair changes.

[0064] In some scenarios, the physical machine where the first cloud server or the second cloud server is located may not be able to provide services. In this case, the first cloud server or the second cloud server can be hot migrated to a new physical machine. When the physical machine changes, the cloud management and control module will re-issue the address of the changed first elastic network card interface or the second elastic network card interface, and save the address of the changed first elastic network card interface or the second elastic network card interface to the ENI pair data structure. Based on the address of the changed first elastic network card interface or the second elastic network card interface, communication is carried out between the first cloud server and the second cloud server, thereby realizing the hot migration of ECS.

[0065] Similarly, when the second cloud server sends a second data stream to the first cloud server, the second forwarding component in the physical machine where the second cloud server resides can obtain the second data stream through the second elastic network interface in the ENI pair. Based on the ENI type, it determines that the second data stream is sent through the ENI pair. Then, it queries the fast channel of the second forwarding component to obtain the address of the first elastic network interface, that is, the physical machine address of the physical machine where the first cloud server resides. Then, based on the address of the first elastic network interface, the second data stream is sent to the first forwarding component on the physical machine where the first cloud server resides. The first forwarding component then sends the second data stream to the first cloud server.

[0066] The embodiment of the present application implements high-performance data forwarding based on ENI pairs, supports ECS-related functions such as QoS and hot migration, and simplifies the implementation of ECS interconnection.

[0067] In actual application, the physical machine where the first server is located includes a first forwarding component, and the physical machine where the second server is located includes a second forwarding component. The first forwarding component is connected to the first cloud server, and the second forwarding component is connected to the second cloud server.

[0068] The elastic network card interface pair is specifically used to communicate between the first cloud server and the second cloud server through the first forwarding component and the second forwarding component based on the address of the first elastic network card interface or the address of the second elastic network card interface.

[0069] That is, the first forwarding component is a component for data forwarding in the physical machine where the first cloud server is located, and the second forwarding component is a component for data forwarding in the physical machine where the second cloud server is located. The first forwarding component and the second forwarding component form a path of the ENI pair.

[0070] The ENI pair data structure can be stored in the first forwarding component and the second forwarding component. Specifically, the first forwarding component can store the address of the local first ENI interface in addition to the address of the peer's second ENI interface. The second forwarding component can also store the address of the local second ENI interface in addition to the address of the peer's first ENI interface.

[0071] When the first cloud server sends the first data stream to the second cloud server, the first forwarding component determines that the first data stream is sent through the ENI pair based on the ENI type, then queries the address of the second elastic network card interface from the data structure of the ENI pair saved by the fast channel, sends the first data stream to the second forwarding component, and the second forwarding component sends the first data stream to the second cloud server.

[0072] Similarly, when the second cloud server sends the second data stream to the first cloud server, the second forwarding component determines that the data packet is sent through the ENI pair based on the ENI type, and then queries the address of the first elastic network card interface from the data structure of the ENI pair saved by the fast channel, sends the second data stream to the first forwarding component, and the first forwarding component sends the second data stream to the first cloud server.

[0073] Thus, the ENI pair is implemented to communicate between the first cloud server and the second cloud server through the first forwarding component and the second forwarding component.

[0074] The data structure of the ENI pair is stored in the fastpath of the first forwarding component and the fastpath of the second forwarding component, so that the address of the first elastic network card interface or the address of the second elastic network card interface can be obtained more quickly without occupying the forwarding resources of the slowpath of the first forwarding component and the second forwarding component.

[0075] See also Figure 5As shown, a schematic diagram of an exemplary implementation of a cloud network-based data transmission method provided by an embodiment of the present application is shown. In this example, the first cloud server ECS1 runs on physical machine 1, and the first forwarding component vswitch1 is connected to ECS1 and runs on physical machine 1. The second cloud server ECS2 runs on physical machine 2, and the first forwarding component vswitch2 is connected to ECS2 and runs on physical machine 2. ECS1 and ECS2 are connected through an ENI pair. The management and control module sends the mounting information of the ENIpair, that is, the physical machine address of physical machine 1 and the physical machine address of physical machine 2 are attached to the data structure of the ENI pair, and saved in the fastpath of vswitch1 and vswitch2.

[0076] When the first data stream is sent from ECS1, for example, the final destination address of the first data stream is dst0, and the source address is src0. vswitch1 only performs resource restrictions and management at the QoS level, such as speed limiting the first data stream. vswitch1 determines that the first data stream is sent through the ENI pair based on the ENI type, and queries the physical machine address of physical machine 2 based on the data structure of the ENI pair. The first data stream is encapsulated, and the inner layer of the encapsulated data packet carries the source address src0, the destination address dst0, the source MAC address, and the destination MAC address, and the outer layer carries the address of physical machine 1 and the address of physical machine 2. Among them, the source MAC address and the destination MAC address are the MAC addresses assigned to the ENI pair. After the encapsulated data packet is sent to vswitch2, the data packet is decapsulated, sent to ECS2 based on the destination MAC address, and the corresponding QoS policy is executed.

[0077] In the communication process between ECS1 and ECS2, the embodiment of the present application does not require VPC network planning, VPC routing, or security policies. There is no single-flow bottleneck problem caused by the tunnel. Data forwarding performance can be optimized to the extreme, and it can be used for interconnection of multiple network elements.

[0078] In practical applications, the definition of ENI pair can be further expanded. In one possible implementation, the first elastic network interface is connected to at least one first cloud server, and / or the second elastic network interface is connected to at least one second cloud server.

[0079] When both ends of the ENI pair, the first elastic network interface ENI1 and the second elastic network interface ENI2, are connected to one ECS, a common ENI pair is formed. See FIG6( a ), which shows a schematic diagram of such an ENI pair.

[0080] When one end of the ENI pair is a bondENI (parent ENI), and the bondENI includes multiple workENIs (child ENIs), then one end of the ENI pair can be connected to multiple ECSs, and multiple ECSs provide the same service to achieve high availability. The data stream can be sent to any of the multiple ECSs. Referring to Figure 6(b), a schematic diagram of this type of ENI pair is shown, which is equivalent to an ENI pair formed by an ENI and a bondENI. For example, the first elastic network card interface ENI1 can be connected to an ECS, and the second elastic network card interface as a bondENI (parent ENI) can include multiple workENIs (child ENIs), and each child ENI can be connected to an ECS.

[0081] When both ends of an ENI pair are bondENIs, and multiple workENIs are included after the bondENI, both ends of the ENI pair can be connected to multiple ECSs. See Figure 6(c), which shows a schematic diagram of this type of ENI pair, which is equivalent to an ENI pair formed by a bondENI and a bondENI. For example, the first elastic network interface, as a bondENI (parent ENI), can include multiple workENIs (child ENIs), each of which can be connected to an ECS. The second elastic network interface, also as a bondENI (parent ENI), can include multiple workENIs (child ENIs), each of which can be connected to an ECS.

[0082] In the embodiments of the present application, ENI pair can be combined with technologies such as bondENI to achieve high availability of ECS.

The elastic network card interface pair is independently deployed in the subnet in the cloud network, that is, it does not belong to any subnet and VPC. When two cloud servers perform data transmission, after receiving the first data stream transmitted via the first elastic network card interface, the address of the second elastic network card interface is queried in the fast channel, and the first data stream is forwarded to the second cloud server based on the address of the second elastic network card interface. Communication based on the address of the second elastic network card interface does not require VPC routing, and the implementation is relatively simple. At the same time, since the elastic network card interface pair does not belong to the VPC, it is not necessary to execute all the functions of the VPC during data transmission, which improves the data transmission performance.
