Patent ID: 8374125

Claim:
An application-specific integrated circuit (ASIC), comprising: switch circuitry for receiving a data frame from a first port and forwarding it to a selected access point on a predetermined port selected from a plurality of access points associated with a plurality of predetermined ports; conversion circuitry in communication with the switch circuitry for converting a data frame between a first protocol and a second protocol; and a memory mapped interface accessible to the plurality of wireless access points in data communication with the switch circuitry; wherein the conversion circuitry converts the data frame from a first protocol to a second protocol and the switch circuitry stores the converted data frame in the memory mapped interface in a memory corresponding to the selected access point; and wherein the switch circuitry is configured to transfer the data frame from the memory area associated with the selected access point to a second memory area corresponding to a second of the plurality of access points responsive to determining that a wireless client to receive the data frame has roamed from the first access point to the second of the plurality of access points.
