One embodiment of the present invention provides a switch system. The switch includes a port that couples to a server hosting a number of virtual machines. The switch also includes a link tracking module. During operation, the link tracking module determines that reachability to at least one end host coupled to a virtual cluster switch of which the switch is a member is disrupted. The link tracking module then determines that at least one virtual machine coupled to the port is affected by the disrupted reachability, and communicates to the server hosting the affected virtual machine about the disrupted reachability.

Advanced link tracking for virtual cluster switching

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 system. The switch includes one or more ports on the switch configured to transmit packets encapsulated based on a first protocol. The switch further includes a control mechanism. During operation, the control mechanism forms a logical switch based on a second protocol, receives an automatically assigned identifier for the logical switch without requiring manual configuration of the identifier, and joins a Ethernet fabric.

Fabric switching

One embodiment of the present invention provides a network device that facilitates configuration orchestration. During operation, the system interprets a configuration command and stores a data structure representing a set of business logic. The business logic can be triggered by the configuration command, a local condition, or both. Furthermore, the system configures the switch according to an outcome of the business logic.

System and method for network configuration

One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a storage device, a hardware management apparatus, and a layer-2 management apparatus. The storage device stores a forwarding table, which includes an entry comprising a MAC address and an egress port for the MAC address. The hardware management apparatus determines whether a destination MAC address of a frame is present in a hardware table in memory of the switch. The layer-2 management apparatus, in response to a determination that the destination MAC address is not present in the hardware table, looks up a first entry comprising the destination MAC address in the forwarding table, and creates a second entry comprising the destination MAC address in the hardware table based on the first entry.

Progressive MAC address learning

One embodiment of the present invention provides a switch. The switch includes a logical channel apparatus and a tunnel apparatus. The logical channel apparatus associates a logical channel identifier of a logical channel with the switch and assigns an Internet Protocol (IP) address as switch identifier of the switch. The logical channel includes a plurality of member switches and the switch is a member switch of the logical channel. The IP address uniquely identifies the switch in the logical channel. The tunnel apparatus establishes a tunnel with a remote switch in the logical channel. An inter-switch packet from the switch is encapsulated in a tunnel header associated with the tunnel.

IP-based interconnection of switches with a logical chassis

One embodiment of the present invention provides a switch. The switch is configurable to be a member of a first fabric switch. The switch includes a link aggregation module. During operation, the link aggregation module marks an ingress-switch field of a frame with a virtual switch identifier. This virtual switch identifier is associated with the switch and a second switch, which is a member of a second fabric switch, and is from a range of identifier associated with the first fabric switch and the second fabric switch. Each of the first fabric switch and the second fabric switch is operable to accommodate a plurality of switches and operate as a single switch.

Virtual link aggregations across multiple fabric switches

One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a network extension module, which maintains a mapping between a first virtual local area network (VLAN) identifier and a first global VLAN identifier of a network extension group. The network extension group is represented by a range of global VLAN identifiers for a tenant. A global VLAN identifier is persistent in a respective switch of the network and represents a virtual forwarding domain in the network. During operation, the network extension module includes the global VLAN identifier in a packet belonging to the first VLAN.

Network extension groups of global VLANs in a fabric switch

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 system. The system includes a high availability module and a data transformation module. During operation, the high availability module identifies a modified object belonging to an application in a second system. A modification to the modified object is associated with a transaction identifier. The high availability module also identifies a local object corresponding to the modified object associated with a standby application corresponding to the application in the second system. The data transformation module automatically transforms the value of the modified object to a value assignable to the local object, including pointer conversion to point to equivalent object of the second system. The high availability module updates the current value of the local object with the transformed value.

Transparent high availability for stateful services
