Some input parameters or intermediate results in the flow allow for manual intervention adjustments to help improve accuracy.
The flow in fig. 1 may include the steps of:
s101: in a cloud converged environment, an SDN controller determines Fabric to be interconnected with a tenant.
The Fabric refers to a network site, a software defined network (Software Defined Network, SDN) controller is a novel network innovation architecture, and is an implementation manner of network virtualization, and the cloud network convergence scenario refers to a scenario in which a cloud platform and the SDN controller cooperatively issue services.
In some embodiments of the present application, before an SDN controller determines Fabric that needs to be interconnected with a tenant, a cloud network convergence environment needs to be pre-networked, and after a plurality of cloud network convergence environments are respectively and successfully networked, a plurality of SDN controllers in each cloud network convergence environment respectively obtain different pre-partitioned Fabric; the cloud network convergence environment configuration is completed with corresponding bottom configuration, so that different BGP EVPN control planes are arranged among the cloud network convergence environments. BGP EVPN is a control layer protocol.
That is, the cloud network convergence environments are respectively networked, different sites are divided in each cloud network convergence environment through a set of SDN controllers, and corresponding bottom layer configurations such as BGP, EVPN and the like are respectively configured. And each cloud network fusion environment is provided with different BGP EVPN control planes respectively.
In addition, the broadcasting message mode between the cloud network fusion environments is head end copy, and the broadcasting message mode between the Fabric in the cloud network fusion environments is multicast and/or head end copy. That is, the broadcasting message mode in each Fabric can use the head end copy, or can use the multicast, and the broadcasting message mode between the cloud network fusion environments can only use the head end copy.
S102: and binding the tenant with the Fabric, and determining a corresponding binding relation.
Specifically, the SDN controller determines an identity of the tenant, and then binds the identity with the Fabric, thereby obtaining a corresponding binding relationship.
S103: and monitoring the binding relation through a bottom layer module of the switch, configuring the switch with the Multi-Site characteristic in the Fabric through preset configuration information, and determining the switch with the Multi-Site characteristic as BGW.
Note that, in the Fabric area, a switch having a Multi-Site characteristic is included, and a switch not having a Multi-Site characteristic is included.
In some embodiments of the present application, an SDN controller issues a binding relationship to a database, which is pre-built in the SDN controller, i.e. the database is the SDN controller's own database. And if the binding relation is monitored in the database, the bottom layer module carries out Multi-Site characteristic configuration on the BGW.
That is, after the SDN controller synchronizes the tenants of the cloud platform, the tenants can automatically bind different Fabric supporting Multi-Site characteristics and serving as BGW roles, the binding relationship is issued to the database, and after the bottom module monitors that the binding relationship exists in the database, the Multi-Site characteristic configuration is performed on the BGW.

The SDN controller configures corresponding Internet interconnection protocol (Internet Protocol, IP) addresses respectively for the direct connection ports between the local BGW and the opposite BGW, and issues the IP address of the direct connection port of the opposite BGW in the BGP of the local end, and after the configuration is completed, the local BGW and the opposite BGW automatically establish a tunnel VXLANtennel.
It should be noted that if the link created in S103 is not open, a tunnel cannot be established.
In some embodiments of the present application, after the SDN controller performs interconnection configuration on the BGW and the BGW in the other cloud network convergence environment, the SDN controller also determines whether a corresponding tenant has a binding relationship, and if not, the SDN controller issues the configuration to all the bound Fabric, and if not, only issues the configuration to the default Fabric.
Specifically, a tenant creates service information on a cloud platform, the service information comprises services such as a network and a route, a corresponding virtual machine is established, the service information is issued to an SDN controller through the virtual machine, the SDN controller determines the tenant corresponding to the virtual machine, whether the corresponding tenant is matched with the tenant or not is judged, if yes, the service information is issued to Fabric, and if not, the service information is issued to default Fabric.
After the SDN controller issues the bound Fabric, in the Fabric, the service is copied at the head end of the Multi-Site characteristic configured in the tunnel through the network service, for example, in the case of a binding relationship, the issuing network configures the head end copy of the Multi-Site characteristic under the L2 VNI of the tunnel of the BGW, and sends the service information to the network device connected to the opposite end BGW through the local end BGW. Therefore, virtual machines created by the cloud platform can be interconnected in a cloud network fusion environment or a cross-cloud network fusion environment, and any virtual machine can access an external device connected with the BGW.
In addition, the Cloud network fusion environment in the embodiment of the application can support various networking modes, such as a combination of BGW and Spine, and scenes such as back-to-back, BGW-to-Cloud, where BGW is placed between Spine and Super Spine, and the like.

The steps S101 to S104 are sequentially described according to the sequence shown in fig. 1 in the embodiment of the present application, so as to facilitate the understanding of the technical solution of the embodiment of the present application by those skilled in the art. In other words, in the embodiment of the present application, the sequence between the steps S101 to S104 may be appropriately adjusted according to the actual needs.
