A system for hybrid broadcast packet replication for virtual local area networks includes a switch operable to receive a packet with an associated VLAN identifier and replicate the packet. A VLAN bit mask is included in the switch to filter the target destinations for the sending the replicated packets. The mask has a first level that provides to the switch an indication of a VLAN group where a radio of an AP has an associated client device. The mask has a second level where the mask provides to the switch an indication of a WLAN where a radio of an AP has an associated client device. The mask can have a third level where the mask provides to the switch an indication of a list of VLANs in use by each WLAN. The switch can then send those replicated packets filtered through the mask on to target devices of the identified VLAN.

A method and apparatus of establishing a connection between a wireless device and a second device includes maintaining a state of the connection between the wireless device and the second device, and receiving an indication that a wireless link to the wireless device has been lost or may be lost. In response to the receiving the indication that the wireless link to the wireless device has been lost or may be lost, the state of the connection is transitioned from a first state to a second state.

A distributed computing system having a distributed protocol stack. In a system including one or more general purpose computers or other application processors for running applications, the distributed protocol stack off-loads communication or other I/O processing from the application processor to dedicated I/O processors using a STREAMS environment thereby enhancing the performance/capacity of the system. The distributed protocol stack is formed of a STREAMS stack top and a stack bottom so that together the stack top and stack bottom comprise a full stack functionally equivalent to a non-distributed stack running on an application processor. Both the application processors and the I/O processors together appear to execute the full protocol stack, but the application processor only executes the stack top while the I/O processor only executes the stack bottom.
