Running a modern business is complex, often meaning that multiple cloud service providers are required to deploy multiple clouds in different geographic locations in order to support all the functionality required in the business process. Therefore, the plurality of cloud service provider networks may include virtual networks of users among a plurality of cloud service providers, for example, the cloud service provider network a belongs to the ari cloud, the cloud service provider network B belongs to the hua cheng cloud, and the cloud service provider network C belongs to the Tencent cloud. The plurality of cloud service provider networks may be located in different countries/regions, for example, the cloud service provider network a belongs to south china, and the cloud service provider network B and the cloud service provider network C belong to north china. The operator mainly provides network service for the user, helps the user to complete access with the cloud service provider network, and completes interconnection and intercommunication among the cloud service provider networks.
At present, the operator network is generally an internet network, and the security of the operator network cannot be guaranteed. Moreover, when the cloud service provider network is a private network created by a user in different cloud service providers, if the cloud service provider networks are to be intercommunicated, complicated manual configuration is required, and the process is complicated, so that automatic interconnection between the private networks on the cloud service provider side cannot be realized.
Therefore, in order to implement automatic interconnection and secure mutual access between private networks of different cloud service providers, embodiments of the present application provide a hybrid cloud network connection method, which can be implemented by a hybrid cloud network connection system as shown in fig. 2.

The second controller 204 is in communication connection with the cloud service provider network 206 through a southbound interface, and the second controller 204 integrates the private access capabilities of a plurality of cloud service providers, so as to realize control and management of the cloud service provider network resources.
The private network 205, which is a private communication network provided by an operator for enterprise users, covers a specific area, serves a specific object, and has high reliability and controllability. Cloud service provider network 206 includes a cloud service provider network 206A that the user creates within cloud service provider a, and a cloud service provider network 206B that the user creates within cloud service provider B.
It should be noted that fig. 2 is only an exemplary architecture diagram, and the network architecture may include other functional units besides the functional units shown in fig. 2, which is not limited in this embodiment of the present application.
The embodiment of the application provides a hybrid cloud network connection method, which is applied to a hybrid cloud network connection system shown in fig. 2. For example, fig. 3 provides a flow chart of a hybrid cloud network connection method. As shown in fig. 3, the method may include S301-S305:
s301, the global controller receives a hybrid cloud network connection request sent by the hybrid cloud management platform.
The hybrid cloud network connection request comprises network information required by a hybrid cloud service; the network information comprises information of a target private network and information of a target cloud service provider network; and the hybrid cloud service is carried through the target private network and the target cloud service provider network.
To construct a hybrid cloud network, a cloud virtual network meeting business requirements needs to be created, secure access between an enterprise network and the cloud virtual network is established, and interconnection between the cloud virtual networks is established. The business requirement of the user is to construct a hybrid cloud network, so the target also has a meaning corresponding to the business requirement. The hybrid cloud service is borne by a target private network and a target cloud service provider network, and comprises the steps of establishing a cloud virtual network meeting service requirements in the target cloud service provider network, realizing the safe access of the private network and the cloud service provider network through a private line channel, and further realizing the interconnection between the target cloud service provider networks through cross-domain connection in the target private network. The private network is a private communication network provided by an operator for enterprise users, covers a specific area, serves specific objects, and has high reliability and controllability.
The global controller is provided with a plurality of northbound interfaces which are communicated with the hybrid cloud management platform, and the global controller receives various service requests sent by the hybrid cloud management platform through the northbound interfaces. The hybrid cloud management platform encapsulates the hybrid cloud network connection request into a representational layer state transfer (RESTFUL) message, and sends the message to the global controller.
The hybrid cloud network connection request includes network information required for constructing the hybrid cloud network, that is, information of network devices included in the hybrid cloud network and corresponding device configuration information, and can be divided into information of a target private network or information of a target cloud service provider network according to a network side. Optionally, the information of the target private network includes: a location of each first network device of the one or more first network devices, an identification of each first network device, and one or more ports of each first network device, virtual route forwarding vrf and route distinguisher/route target RD/RT of each first network device, VLAN-I D for each port, bandwidth for each port, routing protocol for each port, network address for each port; wherein the first network device comprises a device in the target private network. The information of the target cloud service provider network comprises: a cloud service provider of the target cloud service provider network, a service area of the target cloud service provider network, a location of each of one or more second network devices, an identification of each second network device and one or more ports of each second network device, virtual route forwarding vrf and route distinguisher/route target RD/RT of each second network device, a VLAN-ID of each port, a bandwidth of each port, a routing protocol of each port, a network address of each port; wherein the second network device comprises a device in the target cloud service provider network.
After receiving the hybrid cloud network connection request, the global controller analyzes the type of the network information in the hybrid cloud network connection request, namely the information belonging to the target private network or the information of the target cloud service provider network, and sends communication messages to the first controller or the second controller according to the type of the network information, so that the target private network and the target cloud service provider network are deployed respectively.
S302, the global controller sends a first message to the first controller.
The first message comprises information of a target private network and is used for indicating the first controller to complete configuration of required network equipment in the target private network according to the information of the target private network.
Illustratively, the information of the target private network included in the first message can instruct the first controller to send corresponding configuration information to each first network device, so as to complete the configuration of the required network device in the target private network. On one hand, the first message instructs the first controller to determine a target private network device in the first network device, that is, a network device in the target private network for establishing a connection with a target cloud service provider network, complete configuration of the target private network device, and instruct the target private network device to create a private line channel with the cloud service provider network. On the other hand, the target private network device is located in a service area of the target cloud service provider network, and the first message is also used for indicating the first controller to complete configuration of other first network devices because the target private network is located in different countries/regions, so that cross-domain connection in the target private network is realized.
Accordingly, the first controller performs the following step S303 after receiving the first message.
S303, the first controller completes configuration of the first network equipment according to the information of the target private network and indicates the target private network equipment to establish a private line channel with the target cloud service provider network equipment.
Optionally, the first controller receives the first message, stores the first message in the database, cyclically reads the information of the first network device and the configuration message thereof included in the first message, converts the configuration message of the first network device into configuration protocol messages, and sends the configuration protocol messages to the corresponding first network devices respectively, thereby completing configuration of the first network device and connecting cross-domain connection in the target private network. For a target private network device in the first network device, the first controller further needs to configure a route between the target private network device and a target cloud service provider network device, and instruct the target private network device to establish a private line channel with the target cloud service provider network device.
The sequence numbers of step S302 and step S304 do not mean the execution sequence, and for the global controller, S302 and S304 belong to a parallel relationship.
And S304, the global controller sends a second message to the second controller.
The second message comprises information of a target cloud service provider network and is used for indicating the second controller to call the private line access capability of the corresponding cloud service provider according to the information of the target cloud service provider network and create a private line channel between the target cloud service provider network and the target private network. In other words, the information of the target cloud service provider network included in the second message is used to instruct the second controller to create cloud resources required for the hybrid cloud service in the target cloud service provider network and instruct the target cloud service provider network to create a private channel with the target private network.
Accordingly, the second controller performs the following step S305 after receiving the second message.
S305, the second controller calls the private line access capability of the corresponding cloud service provider according to the information of the target cloud service provider network, and instructs the target cloud service provider network equipment to create a private line channel with the target private network equipment.
The second controller integrates the private access capabilities of a plurality of cloud service providers corresponding to the hybrid cloud service, and the private access capabilities are used for the target cloud service provider network to access the target private network; the target cloud service provider network device is a network device located in the target cloud service provider network and adjacent to the target private network.
Illustratively, the target cloud service provider network device is a virtual border router.
Different cloud service providers have own set of private access rules and own controllers to manage and control their cloud resources. The second controller provided in the embodiment of the application integrates the private line access capability of each cloud service provider into one controller, and the cloud service provider provides the private line access capability and a stable and open Software Development Kit (SDK) to the second controller, so that when the private line access capability of a certain cloud service provider is needed, the cloud resource of the cloud service provider can be managed and controlled only by calling the corresponding private line access capability of the cloud service provider.
In one example, the second controller instructs the target cloud service provider network device to create a private line channel with the target private network device by:
the method comprises the following steps: the second controller creates a private network VPC of the user in a service area of the target cloud service provider network.
Optionally, the second controller first queries whether the user has a VPC in the service area, and if so, does not create the VPC.
Step two: a virtual border router is created for accessing the VPC.
Illustratively, the second controller selects network equipment adjacent to the target private network according to the existing circuit physical channel of the cloud service provider district where the VPC is located and the position of the target private network equipment, and creates the virtual boundary router.
Step three: and configuring a routing table of the virtual boundary router.
Wherein the virtual border router is further configured to access the target private network, and the routing table is configured to indicate a route between the virtual border router and the VPC and a route between the virtual border router and the target private network device.
According to the hybrid cloud network connection method, a global controller receives a hybrid cloud network connection request sent by a hybrid cloud management platform, wherein the hybrid cloud network connection request comprises network information required by a hybrid cloud service, the global controller sends information of a target private network to a first controller, instructs the first controller to complete configuration of network equipment required in the target private network according to the information of the target private network, sends information of a target cloud service provider network to a second controller, instructs the second controller to call private line access capacity of a corresponding cloud service provider according to the information of the target cloud service provider network, and creates a private line channel between the target cloud service provider network and the target private network, so that automatic connection of the hybrid cloud network is achieved. Compared with the prior art, private networks of different cloud service providers are manually configured, and mutual access of the private networks is realized through the Internet. According to the hybrid cloud network connection method, automatic connection of the hybrid cloud network can be achieved, labor cost and the probability of failure of manual configuration are reduced, and the safety of a hybrid cloud network architecture is guaranteed by means of the high reliability and controllability of a private network.
In order to enhance the consistent experience of the user and help the user to better manage the cloud computing resources of the user, the embodiment of the present application provides another hybrid cloud network connection method, which is applied to the hybrid cloud network connection system shown in fig. 2. As shown in fig. 4, before step S301, the method further comprises S401-S402:
s401: the hybrid cloud management platform receives service requirement information input by a user.
The hybrid cloud network architecture includes two parts: the cloud and the intercommunication link between the clouds correspondingly, the service requirement information input by the user also comprises two parts: the method comprises the steps of cloud creation requirement information and intercommunication requirement information between clouds. The cloud creation demand information comprises the cloud service provider type and the local city of the target cloud service provider network; the cloud intercommunication demand information comprises a source end, a destination end, link on-off information, link bandwidth and a routing protocol of an intercommunication link between target cloud service provider networks.
Illustratively, the hybrid cloud management platform provides a front-end interface facing a user, and the user logs in an account number of the user in the interface, fills in service information, builds a custom hybrid cloud network, and defines a communication target of the hybrid cloud network. For example: creating cloud A in the Beijing cloud resource pool in Tencent, creating cloud B in the Shenzhen cloud resource pool in Huaye, creating cloud C in the Shanghai cloud resource pool in Ali, and communicating cloud A and cloud C with cloud B.
Further illustratively, the user may also define its communication details for the hybrid cloud network, such as: the communication detail information which is not defined by a user, such as link bandwidth, QoS (quality of service) grade, routing protocol, link on-off information and the like, is set by the hybrid cloud management platform in a default mode.
S402: and the hybrid cloud management platform converts the service requirement information into network information.
The network information comprises information of a target private network and information of a target cloud service provider network.
For a detailed description of the information of the target private network and the information of the target cloud service provider network, refer to step 301 above, which is not described herein again.
For example, the hybrid cloud management platform first needs to determine, according to the cloud creation requirement information, a cloud service provider domain to which a target cloud service provider network belongs and an existing circuit physical channel of the cloud service provider domain, determine second network equipment for carrying the target cloud service provider network, and determine equipment configuration information of the second network equipment according to the service requirement information.
