S102, generating a theme instance based on the message queue model, and establishing a corresponding relation between the theme instance and the network instance.
Wherein the message queue model comprises a point-to-point model and a publish-subscribe model. In the embodiment, a publish-subscribe model is mainly used, and a mechanism of the message queue model is used for realizing the software defined network. In other embodiments, a peer-to-peer model may be used to implement a software defined network.
And generating a theme instance based on the message queue model, specifically triggering and creating the theme instance according to the monitored network instance, wherein the theme instance is a theme (Topic) generated based on the message queue model. The topic represents a set of functions, is a virtual channel connecting a producer and a consumer, and is an important hub for realizing a publish-subscribe message model.
Wherein, the Producers (Producers) are the Producers of the data information and issue the produced data information to the Topic; consumers (Consumers) subscribe to newly added data messages in real time from Topic for users of the data messages.
After the Topic instance is created based on the message queue model according to the monitored network instance trigger, Topic instance identifications of the Topic instance can be further obtained, and the obtained Topic instance identifications are, for example, Topic1, Topic2 and Topic 3.

Specifically, as shown in fig. 2, step S102 includes: sub-steps S102a to S102 c.
And S102a, acquiring the preset module type.
The preset module type is a type corresponding to an object set formed by classifying network objects in the network instance according to the network attribute of the software defined network.
For example, the network object of the created network instance is divided into a two-layer network type and a three-layer network type according to the hierarchical network attribute of the software defined network, wherein the two-layer network type and the three-layer network type correspond to a two-layer network module and a three-layer network module, respectively.

For example, the object extraction is performed on the network instance according to the two-layer network type and the three-layer network type to obtain a two-layer network module and a three-layer network module corresponding to the network instance.
Specifically, the network object in the created network instance is abstracted into two modules, which are respectively: the system comprises a two-layer network module and a three-layer network module, wherein the two-layer network module solves the forwarding problem of the Ethernet message, for example, the two-layer network module comprises the functions of port online, Address Resolution Protocol (ARP) learning, two-layer forwarding table synchronization and the like; and the three-layer network module solves the routing forwarding problem of the IP message.
S102c, generating a theme instance corresponding to the module type based on the message queue model, and establishing a corresponding relation between the theme instance and the network module according to the module type.
Specifically, a first type of theme instance and a second type of theme instance are generated based on the message queue model; and establishing a corresponding relation between the theme instance of the first type and a two-layer network module, and establishing a corresponding relation between the theme instance of the second type and a three-layer network module.
The theme instance of the first type may be one theme instance or multiple theme instances; the second type of topic instance may be one topic instance or multiple topic instances.
For example, when the topic instance of the first type and the topic instance of the second type both include a plurality of topic instances, the establishing a correspondence between the topic instance of the first type and a layer-two network module and the establishing a correspondence between the topic instance of the second type and a layer-three network module includes: and establishing a corresponding relation between the network object of the two-layer network module and the plurality of theme instances in the first type of theme instances, and establishing a corresponding relation between the network object of the three-layer network module and the plurality of theme instances in the second type of theme instances. Thereby increasing the flexibility of the software defined network.
S103, acquiring data information generated by the network instance, and publishing the data information to the theme instance corresponding to the network instance according to the corresponding relation.
Specifically, acquiring the data information generated by the network instance refers to acquiring the data information generated by the publishing object of the network instance, and publishing the generated data information to the corresponding Topic so that the subscribing object subscribes to the data information. The publishing object and the subscribing object refer to part of the network objects of the network instance.
Specifically, the acquiring data information generated by the network instance and publishing the data information to the topic instance corresponding to the network instance according to the corresponding relationship includes: and acquiring data information generated by a two-layer network module and a three-layer network module of the network instance, publishing the data information generated by the two-layer network module to the first type of theme instance, and publishing the data information generated by the three-layer network module to the second type of theme instance.
The release object corresponding to the two-layer network module comprises: modules of various layer2, such as bridge, ovs, vSwitch, physical switch, include controller modules, such as VMware vCenter, OpenStack, and so forth.
The subscription object corresponding to the two-layer network module comprises: and layer2 modules of all access networks, such as network elements of vSwitch/OVS/TOR and the like accessing VM or PM Instance, VNI interfaces and the like.
The release object of the three-layer network module comprises: routers, networks, and controllers, etc. The router can actively release various routing entries of a routing table in the router, including static routing and various dynamic routing protocols; the gateway can actively release a route corresponding to the opposite end of the gateway, for example, a default route is arranged on the NAT gateway, a route of an IP address field of the opposite end is arranged on the VPN gateway, and the like; and the routing information actively issued by the user can be issued by the controller.
A subscription object for a three-tier network module, comprising: network elements such as vSwitch/OVS/TOR and the like with flow table forwarding capability; a router class selectively synchronizing the learned routing entries in Topic according to rules; gateway class, routing entries learned in the selective synchronization topic instance.
In one embodiment, the obtaining data information generated by the network instance and publishing the data information to the topic instance corresponding to the network instance according to the corresponding relationship includes:
acquiring a two-layer forwarding table and data information generated by a two-layer network module of the network instance; and converting the data information into a data information table according to the two-layer forwarding table, and issuing the data information table to the first type of subject instance. The data information generated by the two-layer module is converted into the data information table by utilizing the two-layer forwarding table in the two-layer network type and is published to the theme instance of the first type, so that the efficiency of subscribing the data information of the theme instance can be improved, and meanwhile, the later query is facilitated.
Table 1 is a two-layer forwarding table
| MAC address | Source host machine | VTEP IP |
| MAC1 | Host1 | IP1 |
| MAC2 | Host2 | IP2 |
| MAC3 | GW Interface | IP3 |
In table 1, the MAC address of the calling procedure and the host from which VTEP IP is derived are recorded, where VTEP IP is the underlying tunnel IP address in the Overlay network scenario.
Therefore, different topics can be flexibly developed for network modules of network instances or network objects in the network modules, and various heterogeneous computing systems can be guaranteed to be accessed into the network, specifically, a two-layer network. For example, both layer2 port online flow and controller online flow are supported.
S104, subscribing the data information of the theme instance, and finishing the corresponding function of the network instance according to the data information to realize the software defined network.
Specifically, a consumer in the network instance subscribes the data information of the Topic, and performs corresponding actions according to the data information to complete corresponding functions, thereby realizing the software defined network. Such as maintaining local two-layer forwarding table information, or implementing applications for various network scenarios.
For example, as shown in fig. 3, the controller issues a message on Topic1, a route (10.0.1.0/24) needs to be added in the network, and the next hop is directed to router 2.
Both router 1 and gateway 1 subscribe to data information in Topic1 (subject instance), and execute corresponding action according to the data information to complete corresponding function, so there are the following logics: router 1 issues a routing table and 10.0.1.0/24 next hop points to the IP of router 2. Gateway 1 is a gateway with some function on router 1, for example, Site to Site VPN, where 10.0.1.0/24 is also set on the VPN gateway and the next hop is directed to router 1.
Therefore, the flexible definition of three-layer network forwarding can be realized through the subscription publishing model, the planning and setting of all networks can be automatically completed in a one-stop mode by a client, and the forwarding of the whole network can be realized as long as a definite routing requirement exists. Meanwhile, seamless connection of various dynamic routing protocols can be realized, languages of various routing protocols are unified into a model of a message queue, and application of various network scenes is realized.
The implementation method of the software defined network provided by the embodiment monitors the created network embodiment; generating a theme instance based on the message queue model, and establishing a corresponding relation between the theme instance and the created network instance; acquiring data information generated by the network instance, and storing the data information generated by the network instance to a corresponding theme instance according to the established corresponding relation; and subscribing the data information of the theme instance, and realizing the software defined network according to the data information. The idea of the centralized controller of the software defined network is dispersed into a plurality of theme instances, and each time one network instance is created, a corresponding theme instance is generated in time, so that the automatic setting of the whole network is realized, the single-point control problem of the system is solved, a fully distributed system consisting of a plurality of theme instances is formed, and the flexibility and the reliability of the software defined network are further improved.
Referring to fig. 4, fig. 4 is a schematic flowchart of another implementation method of a software-defined network according to an embodiment of the present application.
As shown in fig. 2, the method for implementing the software defined network specifically includes steps S201 to S206.
S201, monitoring a network instance established by a user based on a software defined network, and acquiring a network instance identifier of the network instance.
Specifically, the monitoring user may establish one VPC or multiple VPCs, such as VPC1, VPC2, VPC3, based on the established virtual private cloud of the software defined network. Network instance identifications, such as VPC1, VPC2, and VPC3, of the network instance are obtained.
S202, generating a theme instance based on the message queue model, and deploying the theme instance in a containerized high-availability cluster.
Specifically, a Topic instance is created according to the monitored network instance trigger, the Topic instance is a Topic (Topic) generated based on a message queue model, and the Topic instance is deployed in a containerized high-availability cluster, so that the reliability of the network is provided.
As shown in fig. 5, multiple Topic instances generated based on the message queue model are deployed in a containerized high availability cluster, for example, Topic1, Topic2 to TopicN are deployed in a container cluster based on a high performance network and a server, that is, a containerized high availability cluster, and are used for implementing data publishing subscription between generators (Producers) and consumers (consumers), thereby improving network performance and reliability.
S203, establishing a master-backup relationship among the theme instances.
After all Topic instances (topics) are realized by containerized high-availability clusters, main-standby high-availability deployment can be formed among a plurality of topics, so that the high availability of the network is further realized, and the reliability of the network is improved.
In one embodiment, in order to improve the high availability of the network, the main-standby relationship is established between the multiple topic instances, specifically: and taking each topic instance generated based on the message queue model as a main topic instance, and selecting at least one other topic instance from the plurality of topic instances as a standby topic instance.
For example, topic instances generated based on the message queue model include: the method comprises the following steps of taking Topic1, Topic2, Topic3, Topic4, Topic5 and Topic6 as main theme examples, and taking Topic1, Topic2, Topic3, Topic4, Topic5 and Topic6 as main theme examples, for example, when Topic1 is a main theme example, the corresponding standby theme examples can be any one or more of Topic2, Topic3, Topic4, Topic5 and Topic 6.
In addition, all producer connections with Topic implement a publisher unconnection legacy mechanism, that is, if a producer of Topic causes unconnection due to an exception, a default code is run on Topic, and the default mechanism without a producer is executed, so as to help a consumer execute a default forwarding rule.
For example, for Topic for a two-layer network module, if there is no producer, all forwarding planes forward based on existing means (i.e., existing means of forwarding for software-defined networking), and broadcast if an unknown MAC is encountered.
Furthermore, when a producer is lost, all Topic cannot update the latest forwarding data. The steps of maintaining forwarding data for the current Topic may be performed; if all producers under the high-availability architecture are monitored to be disconnected, operation and maintenance early warning is automatically initiated to trigger emergency repair. Thereby increasing the high availability of the system.
S204, obtaining the subject instance identification of the subject instance, and correspondingly storing the network instance identification and the subject instance identification in a corresponding relation table to realize the establishment of the corresponding relation.
For example, three network instances, which are VPC1, VPC2, and VPC3, are created, and three Topic instances are generated based on the message queue model and Topic instance identifiers of the Topic instances, which are Topic1, Topic2, and Topic3, respectively, are obtained. And correspondingly storing the network instance identifier and the subject instance identifier in a corresponding relation table to realize the establishment of the corresponding relation, which is specifically shown in table 2.
Table 2 is a correspondence table
| Network example | Example of subject matter |
| VPC1 | Topic1 |
| VPC2 | Topic2 |
| VPC3 | Topic3 |
S205, acquiring data information generated by the network instance, and publishing the data information to the theme instance corresponding to the network instance according to the corresponding relation.
Specifically, acquiring the data information generated by the network instance refers to acquiring the data information generated by the publishing object of the network instance, and publishing the generated data information to the corresponding Topic so that the subscribing object subscribes to the data information.
S206, subscribing the data information of the theme instance, and finishing the corresponding function of the network instance according to the data information to realize the software defined network.
Specifically, a consumer in the network instance subscribes the data information of the Topic, and performs corresponding action according to the data information to complete corresponding functions, thereby realizing the software defined network. Such as maintaining local two-layer forwarding table information, or implementing applications for various network scenarios.
The embodiment provides a method for implementing a software defined network, which disperses the idea of an integrated controller of the software defined network into a plurality of topic instances, generates a corresponding topic instance in time when creating one network instance, and establishes a corresponding relationship, thereby implementing automatic setting of the whole network, solving the single-point control problem of the system, and simultaneously deploying the topic instances by using a containerized high-availability cluster, thereby improving the flexibility and reliability of the software defined network.
