Abstract: Embodiments of the present invention provide a method and apparatus for a multi-entity wireless communication adapter, including at least a first connection module to communicate a first signal traffic corresponding to a basic service set station entity, a second connection module to communicate a second signal traffic corresponding to an entity that is not a basic service set station, a shared physical layer to process both the first and the second signal traffics, and a media access controller to control communication of the first and second signal traffics via first and second communication channels, respectively, according to a channel management scheme. Additional features are described and claimed.

Abstract: A system and method of providing security mechanisms for securing traffic communicated from a server system to a client system independent of the state of the client system. The server system determines whether the client system has entered an operational state. When the client system is operational, key exchange processes are initiated between the two systems, the results of the key exchange processes being the parameters for use in securing traffic communication between the two systems. The results are stored in the client system. The results are inhibited from being updated in the client system until the server system is successful in completely executing another set of key exchange processes. The results are updated with the results obtained from successful execution of the other set of key exchange processes if the execution of the other set is successful. The traffic communication is thus secured based on whatever results are stored in the client system.

Abstract: Briefly, a method and apparatus that may enable roaming of a station from a first access point to a second access point by presenting a power saving mode to the first access mode while establishing a secured connection with the second access point.

Abstract: A multiprocessor data processing system includes a private data bus and a private program bus coupled to each of the processors. Coupled between the private data buses is a plurality of memory banks, each of which can be dynamically switched between the processors to move blocks of data without physically transferring the data from one bank to another. Likewise, a plurality of memory banks is coupled between the program buses. These memory banks are loaded with pages of program instructions from external memory over a shared bus. Any one of the pages can be coupled to either of the processors on its respective private program bus. When the pages are coupled to the shared bus, they appear as a contiguous address space. When a page is coupled to one of the private program buses, the addressing mode is changed so that the page is mapped to a common address space.

Abstract: An apparatus and method for arbitrating bus ownership of a first communication bus ("C1-bus") for a plurality of C1-bus masters and arbitrating bus ownership of a second communication bus ("C2-bus") for a plurality of C2-bus masters. The apparatus further performs a DMA transfer, without processor assistance, between a first component coupled to the C1-bus and a second component coupled to the C2-bus.
