Abstract:
1. A method of providing continuous data forwarding during a failure mode in a wireless data network, comprising: establishing one or more tunneled data paths in the wireless data network, each of the one or more tunneled data paths extending between one of a plurality of access points of the wireless data network and a data plane management component of a network switch, each of the one or more tunneled data paths configured detecting a failure of a control plane module of the network switch, the control plane module coupled to the data plane management component of the network switch and to the access points, and configured maintaining by the data plane management component and each access point the one or more tunneled data paths for use by mobile nodes that were authenticated to the wireless data network prior to the failure of the control plane module of the network switch; detecting a recovery of the control plane module of the network switch; and re-authenticating one or more mobile nodes following the recovery of the control plane module, wherein
