HYBRID BROADCAST PACKET REPLICATION FOR VIRTUAL LOCAL AREA NETWORKS
First Claim
1. A system for hybrid broadcast packet replication for virtual local area networks, comprising:
- a switch disposed within at least one wireless local area network (WLAN), the at least one wireless local area network comprising at least one virtual local area network (VLAN), the switch operable to receive a packet with an associated VLAN identifier, wherein the packet is to be broadcast to at least one target device grouped in the identified VLAN, the switch also operable to replicate the packet, anda VLAN bit mask included in the switch, the VLAN bit mask operable to filter the destinations for the sending of the replicated packets using the mask, wherein;
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, andthe 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; and
whereinthe switch is further operable to replicate packets based on the mask and send those replicated packets filtered through the mask on to the at least one target device of the identified VLAN.

Abstract
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.

7. A method for hybrid broadcast packet replication for virtual local area networks, the method comprising the steps of:
-
receiving a packet with an associated VLAN identifier, wherein the packet is to be broadcast to at least one target device grouped in the identified VLAN; replicating the packet based on the destinations for the sending of the replicated packets using a VLAN bit mask, wherein the mask has a first level that provides an indication of a VLAN group where a radio of an AP has an associated client device, and a second level where the mask provides an indication of a WLAN where a radio of an AP has an associated client device; and sending those replicated packets filtered through the mask on to the at least one target device of the identified VLAN. - View Dependent Claims (8, 9, 10, 11)

12. A wireless network switch for hybrid broadcast packet replication for virtual local area networks, wherein the switch is disposed within at least one wireless local area network (WLAN) comprising at least one virtual local area network (VLAN):
-
wherein the switch is operable to receive a packet with an associated VLAN identifier, wherein the packet is to be broadcast to at least one target device grouped in the identified VLAN, the switch is also operable to replicate the packet, and a VLAN bit mask included in the switch, the VLAN bit mask operable to filter the destinations for the sending of the replicated packets using the mask, wherein; 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, and 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; and
whereinthe switch is further operable to replicate packets based on the mask send those replicated packets filtered through the mask on to the at least one target device of the identified VLAN.
