Abstract: A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voiceover-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

Abstract: In some embodiments, an apparatus includes a first controller configured to be operatively coupled within a network having a set of network nodes, a forwarding gateway and a configuration entity. The first controller is configured to manage session state and node state associated with the set of network nodes independent of the forwarding gateway. The first controller is configured to fail over to a second controller when the first controller fails, without the forwarding gateway failing over and without the configuration entity failing over.

Abstract: In some embodiments, an apparatus includes a network node operatively coupled within a network. The network node is configured to send a first authentication message upon boot up, and receive, in response to the first authentication message, a second authentication message configured to be used to authenticate the network node. The network node is configured to send a first discovery message, and receive, based on the first discovery message, a second discovery message configured to be used by the network node to identify an address of the network node and an address of a core network node within the network. The network node is configured to set up a control-plane tunnel to the core network node based on the address of the network node and the address for the core network node and receive configuration information from the core network node through the control-plane tunnel.

Abstract: In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive at a tunnel server, a data unit addressed to a communication device, and define, a first instance of the data unit and a second instance of the data unit. The first instance of the data unit is sent to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network. The second instance of the data unit is sent to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network. The second instance of the data unit is dropped by the communication device when the first instance of the data unit is received before the second instance of the data unit.

Abstract: In some embodiments, an apparatus comprises of a control module implemented in at least one of a memory or a processing device that is configured to receive, via a network and from a wireless access point or an access network node, a control packet defined based on a control protocol. The control packet is associated with at least one control function of the wireless access point or access network node. The control module is configured to determine a status of an access network node based on the control packet from the access network node. The control module is configured to send via the network, a response to the access network node based on the status of the access network node.
