    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 comprises of a first Control And Provisioning of Wireless Access Points (CAPWAP) module implemented in at least one of a memory or a processing device that is configured to be designated as a backup control module for a wireless access point during a first time period. The first CAPWAP control module is configured to receive state information associated with the wireless access point during the first time period from a second CAPWAP control module. The second CAPWAP control module is designated as a primary control module for the wireless access point during the first time period. The first CAPWAP control module is configured to be automatically designated as the primary control module during a second time period after the first time period and in response to the second CAPWAP control module not operating according to at least one predefined criterion.

    Abstract: In some embodiments, an apparatus includes a core network node configured to associate with a native multicast group a first client device that is associated with a first virtual local area network (VLAN) and operatively coupled to the core network node via a first access network node and an aggregation network node. The core network node can associate with the native multicast group a second client device that is associated with a second VLAN and operatively coupled to the core network node via a second access network node and the aggregation network node. The core network node can define a multicast VLAN including the first VLAN and the second VLAN based on the native multicast group. The core network node can receive a multicast data unit associated with the native multicast group and can also define a single instance of the multicast data unit for the multicast VLAN.

    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.
