摘要： Unified mobility switches often define a virtual LAN (VLAN), including a combination of mobility tunnels and access tunnels, via which packets are transported to a mobile device over a combination of physical connections and wireless links. A unified switch may have multiple ports available to route a packet to a particular destination, since the unified switches identify routing paths for both physical connections and VLANs. A particular unified switch may therefore have multiple routes to a common destination, which can lead to a routing loop across a network of switches supporting both physical and virtual connections. A unified mobility switch provides loop detection and prevention through a set of rules for qualifying connections as virtual tunnels or physical connections, and defining a single path where multiple potential paths exist.

摘要： A switch architecture and method provides scaling through multi-level load balancing of flows across data and application processing planes. An input/output module receives a communication session flow (forward) from a client device and selects one of a plurality of data processors to process the flow. The selected data processor determines the level of processing needed for the forward flow and selects an application processor from a plurality of such application processors. The application processor generates a session structure identifying actions to be performed on the forward flow and transfers the session structure to the selected data processor to perform the actions on the forward flow. The application processor also predictively generates and offloads a session structure for the associated reverse flow. If the reverse session structure is offloaded to a different data processor, either the forward or reverse flow redirects packets, or is redirected, to the data processor hosting the other flow. Typically, the redirection is accomplished by offloading a redirection structure as the offloaded session structure.

摘要： Methods, apparatus and a computer program product provide for a Tolerant License Manager that defines a cluster of a plurality of network controllers, wherein each respective network controller contributes at least one license to a current total amount of licenses in a license pool. The Tolerant License Manager identifies at least one threatened access point upon detecting a first network controller has become unavailable. Each threatened access point comprises any access point connected to the first network controller when the first network controller becomes unavailable. The Tolerant License Manager establishes (and/or) approves a connection between a back-up controller and the threatened access point(s). While the first network controller is unavailable, the Tolerant License Manager allocates a license to each threatened access point via the back-up network controller.
