A wireless access point with a centralized media access controller MAC () that enables multiple radios () to share MAC resources and implement load balancing and frequency control.

Media access controller for use in a multi-sector access point array

A switching network for efficiently receiving and transmitting data packets having both frames and messages includes a crossbar switch with a plurality of surrounding ports for exclusively switching frames which normally consist of large data streams of 40 to 60 bytes. Then the ports are connected together in a message ring and small data entity messages, for example 4, 8, or 12 bytes, are switched from an input port to an output port around the ring avoiding congestion of the crossbar switch.

Message ring in a switching network

Variable length switch fabric for switching variable length data packets between input and output transmission paths in a communication network. In one embodiment of the invention, apparatus is provided for switching variable length data packets between input and output transmission paths in a communication network. The apparatus includes a plurality of input ports coupled to receive the plurality of variable length data packets from the input transmission paths and a plurality of output ports coupled to transmit the plurality of variable length data packets on the output transmission paths. The apparatus also includes a variable length switch fabric coupled to the plurality of input ports and the plurality of output ports, the variable length switch fabric operates to switch the plurality of variable length data packets from selected input ports to selected output ports in an unsegmented form.

Data switch and switch fabric

A high data rate switch is disclosed. The switch may include fiber optic channels where a plurality of switching elements necessarily operate at a significantly lower data rate providing routing of variable or fixed size data packets from a plurality of source ports to a plurality of destination ports via a single serial link. This is may be provided by storing the high rate data temporarily in memory in each of the source ports and then downloading it at a lower rate in a complete data packet to a designated switching element, almost immediately distributing the next data packet that has been received by the source port to a next switching element. The switching element configuration provides automatic redundancy and a minimum amount of frame overhead while sustaining throughput at the high data rate.

Parallel channel architecture

Variable length switch fabric

There is disclosed a switching network for efficiently receiving and transmitting data packets having both frames and messages. The switching network includes a crossbar switch with a plurality of surrounding ports for exclusively switching frames which normally consist of large data streams of 40 to 60 bytes. Then the ports are connected together in a message ring and small data entity messages, for example 4, 8, or 12 bytes, are switched from an input port to an output port around the ring avoiding congestion of the crossbar switch.
