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

Systems for performing inline wire speed data deduplication are described herein. Some embodiments include a device for inline data deduplication that includes one or more input ports for receiving an input data stream containing duplicates, one or more output ports for providing a data deduplicated output data stream, and an inline data deduplication engine coupled to said one or more input ports and said one or more output ports to process input data containing duplicates into output data which is data deduplicated, said inline data deduplication engine having an inline data deduplication bandwidth of at least 4 Gigabytes per second.

Inline wire speed deduplication system

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 port to couple to a second switch. The switch also includes a control mechanism configured to maintain a set of configuration information for a virtual cluster switch which includes a number of member switches. The set of configuration information includes global configuration information for the virtual cluster switch and switch-specific configuration information for one or more member switches. In addition, the set of configuration information is replicated and stored at each member switch.

Distributed configuration management for virtual cluster switching

One embodiment of the present invention provides a computing system. The computing system includes processing circuitry, one or more ports, a persistent storage module, and a management module. The persistent storage module stores a plurality of persistent storage instances associated with a plurality of switch groups. A respective persistent storage instance stores configuration information associated with a switch group in a data structure. The management module identifies at least two switch groups, which are associated with a logical network, from the plurality of switch groups and configures a respective virtual network representing the logical network in a respective identified switch group. The management module also maintains a mapping between a respective virtual network and the logical network.

Multi-fabric manager

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.

Online restoration of a switch snapshot

One embodiment of the present invention provides a switch. The switch includes a packet processor, a persistent storage module, and a boot-up management module. The packet processor identifies a switch identifier associated with the switch in the header of a packet. The persistent storage module stores configuration information of the switch in a first table in a local persistent storage. This configuration information is included in a configuration file, and the first table includes one or more columns for the attribute values of the configuration information. The boot-up management module loads the attribute values to corresponding switch modules from the first table without processing the configuration file.

Fast reboot for a switch

Systems for performing inline wire speed data deduplication are described herein. Some embodiments include a device for inline data deduplication that includes one or more input ports for receiving an input data stream containing duplicates, one or more output ports for providing a data deduplicated output data stream, and an inline data deduplication engine coupled to one or more input ports and one or more output ports to process input data containing duplicates into output data which is data deduplicated, where the inline data deduplication engine has an inline data deduplication bandwidth of at least 4 Gigabytes per second.
