Abstract: High availability for a network may be achieved, for example, during a hitless upgrade by creating a replica controller virtual machine of an operating controller virtual machine (source controller). The replica controller virtual machine may be on a same or different server as the source controller virtual machine. The replica controller virtual machine may be copied with processes present in the source controller virtual machine and synchronized for runtime state. Upgrades or changes to software applications run in the source controller virtual machine may be provided to the replica controller virtual machine. Once enabled, the replica controller virtual machine may be operated without suspension of the source controller virtual machine.

Abstract: Management and provisioning of networking traffic may be provided by bundling virtual channels into a group. A global policy may be applied to the bundle so that virtual ports providing services to a client may be managed by referring to the global policy of the bundle. The channels comprising the bundle may span multiple physical ports and in some cases, multiple physical switches. Thus, policy management may be avoided at the port level and instead, be handled as groups of channels implementing a client service.

Abstract: A switch of a data network implements both a bridge and a virtual bridge. In response to receipt of a data frame by the switch from an external link, the switch performs a lookup in a data structure using a source media access control (SMAC) address specified by the data frame. The switch determines if the external link is configured in a link aggregation group (LAG) and if the SMAC address is newly learned. In response to a determination that the external link is configured in a LAG and the SMAC address is newly learned, the switch associates the SMAC with the virtual bridge and communicates the association to a plurality of bridges in the data network.
