Access point groupings bridging tunneled traffic for a communication network
An apparatus and method for access point groupings bridging tunneled traffic for a communication network, includes a first step of associating each access point with a location parameter. A next step includes grouping access points in accordance with the location parameter. A next step includes receiving a packet. A next step includes bridging the packet between Layer-2 tunnels of all access points that are part of a grouping.
1. A method for access point groupings bridging tunneled traffic for a communication network, comprising:
associating each access point with a location parameter;
grouping access points in accordance with the location parameter, wherein the access points of the grouping have Layer-2 tunnels established to two different concentrators of a Network Operations Center;
receiving a packet; and
bridging the packet between Layer-2 tunnels of all access points that are part of the grouping,
wherein the location parameter of one access point is embedded in a multicast Wireless Network Management Protocol roam notification packet received from the one access point by an associated concentrator, and the location parameter is relayed to the other concentrator that is operable to extract the location parameter from the packet and bridge the packet to any of its access points that can be grouped in accordance with the location parameter.
2. The method of claim 1 , wherein the location parameter is a router identification.
3. The method of claim 2 , wherein the grouping includes grouping access points having router identification bytes matching a predetermined common pattern.
4. The method of claim 1 , wherein each access point has a Layer-2 tunnel established to one concentrator.
5. A method for access point groupings bridging tunneled traffic for a communication network, comprising:
associating each access point with a location parameter that is an entry in a neighboring access point list that is part of a table identifying Layer-2 tunnels and Media Access Control addresses for each access point;
grouping access points in accordance with the location parameter;
receiving a packet that is a multicast Wireless Network Management Protocol roam notification received from one access point of the grouping; and
bridging the packet between Layer-2 tunnels of all access points that are part of the grouping by,
checking the source of the roam notification by looking up the one access point in the table,
identifying neighboring access points in the table,
performing a reverse look up for the address and tunnel for the one access point, and
bridging the packets between the tunnels of all access points that are listed neighbors in the table.
6. The method of claim 5 , wherein the neighboring access point list is sanctioned.
7. An apparatus for providing access point groupings bridging tunneled traffic for a communication network, comprising:
at least two concentrators of a Network Operation Center, the at least two concentrators operable to: associate access points of the network with a location parameter on separate Layer-2 tunnels, group the access points in accordance with the location parameter, wherein one concentrator is operable to receive a Wireless Network Management Protocol roam notification packet with the location parameter of one access point embedded therein, and relay the packet to the other concentrator that is operable to extract the location parameter from the packet and bridge the packet to any of its access points that can be grouped in accordance with the location parameter.
8. The apparatus of claim 7 , wherein the location parameter is a router identification.
9. The apparatus of claim 8 , wherein the grouping includes grouping access points having router identification bytes matching a predetermined common pattern.
10. The apparatus of claim 7 , wherein each access point has a Layer-2 tunnel established to one concentrator.
