A method, apparatus and computer program product for performing load balancing of SNDs and FNDs is presented. The presently disclosed method and apparatus for providing load balancing solves the problem of improper wireless traffic distribution in an enterprise network that may cause overload on some FNDs while some others are lightly loaded. The presently described methods and apparatus, by use of a single command, allow a user to restore the FNDs and SNDs to a preplanned topology or balance the load on controllers without overriding the manual assignments specified by the user.

One or more implementations can include methods, systems and computer readable media for elastic wireless control planes. In some implementations, the method can include evaluating one or more elastic wireless control plane mode factors, and partitioning each of a plurality of access points into one of an active mode group and a sleep mode group based on the evaluating. The method can also include determining a number of wireless control plane instances needed based on the partitioning. The method can further include activating the number of wireless control plane instances and shutting down any excess wireless control plane instances beyond the number.

A method, apparatus and computer program product for enhancing redundancy in a wireless system using location attributes is presented. A First Network Device (FND) receives a discovery message from an Access Point (AP). The FND comprises either a Wireless Controller (WC) or a Wireless Switch (WS). The FND uses the location information associated with the AP to determine how many other APs from a same locality are currently allocated to at least one FND, and assigns the AP to a least loaded FND in the locality.

Method for enhancing redundancy in a wireless system using location attributes

A method, apparatus and computer program product for performing location based load balancing of wireless access points and wireless switches is presented. A wireless controller (WC) receives an associate message from an Access Point (AP)/wireless switch (WS) at the WC. The WC then determines whether a preferred WC for the AP/WS is available. When the preferred WC is not available, then the WC determines if an alternate WC for the AP is available. When the alternate WC is not available, an administrator configured policy may be used that maps the AP to a specific WC. When the policy does exist then the AP is coupled to the WC according to the policy and when the policy does not exist then the WC parses the AP/WS location information for the AP/WS to determine an available geographically closest WC for the AP/WS and sends a message to the AP/WS relating to the available WC. The WC will also assign an available geographically closest WS to AP.

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 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.

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.
