A cloud based network includes a plurality of nodes, each of which include at least one containerized microservice that enables intent-driven operation of the cloud based network. One or more resource controllers, each designated to manage a custom resource, communicate with a master controller of the node to manage operational and configuration states of the node and any microservices containerized within the node. The master enables a user to monitor and automate the management of microservices and the cloud based network as a whole. The containerized microservice architecture allows user customizable rendering of microservices, reconciliation of old and new versions of microservices, and facilitated management of a plurality of nodes.

Disaggregated cloud-native network architecture

One embodiment of the present invention provides a switch. The switch includes a switch group module, a persistent storage module, and an allocation module. The switch group module maintains a membership in a switch group. The switch group includes a plurality of switches and operates as a single switch. The persistent storage module stores configuration information associated with the switch group in a data structure in a local persistent storage. The allocation module determines that a second switch is in a default mode and obtains a switch identifier from the persistent storage based on a switch media access control (MAC) address of the second switch. The allocation module then constructs a control message, which is destined for the second switch and includes the switch identifier and a switch group identifier of the switch group.

Identifier assignment to a new switch in a switch group

One embodiment of the present invention provides a switch. The switch includes a switch group module, a persistent storage module, and a distributed configuration management module. The switch group module maintains a membership in a switch group. The switch group includes a plurality of switches and operates as a single switch. The persistent storage module stores configuration information associated with the switch group in a table, which includes one or more columns for attribute values of the configuration information, in a local persistent storage. The distributed configuration management module verifies whether the configuration information is eligible for a distributed commit to the switch group. If the configuration information is eligible for the distributed commit, the distributed configuration management module commits the configuration information to the persistent storage and switch modules of the switch.

Distributed configuration management in a switch group

One embodiment of the present invention provides a switch. The switch includes one or more ports, a switch group module, a persistent storage module, and a synchronization module. The switch group module maintains a membership in a switch group. The persistent storage module stores configuration information associated with the switch group in a data structure, which includes one or more columns for attribute values of the configuration information, in a local persistent storage. The synchronization module obtains update information, which includes a first set of attribute values, from a portable representation. The synchronization module identifies a software version of a second switch in the switch group and generates an update instruction to update the first data structure in a persistent storage in the second switch with target update information. The target update information comprises a second set of attribute values updated from the first set of attribute values.

Multiple software versions in a switch group

One embodiment of the present invention provides a switch. The switch includes one or more ports, a persistent storage module, a restoration module, and a retrieval module. The persistent storage module stores configuration information associated with the switch in a data structure, which includes one or more columns for attribute values of the configuration information, in a local persistent storage. The restoration module instantiates a restoration database instance in the persistent storage from an image of the persistent storage. The retrieval module retrieves attribute values from a data structure in a current database instance and the restoration database instance in the persistent storage. The restoration module then applies the differences between attribute values of the restoration database instance and the current database instance in the persistent storage to switch modules of the switch, and operates the restoration database instance as the current database instance in the persistent storage.
