20150195265 | VIRTUAL PRIVATE NETWORK DEAD PEER DETECTION - Methods and systems are provided for detecting dead tunnels associated with a VPN. An indicator of a tunnel capability, for example, a DPD vendor ID, is received from a peer through a VPN connection. The tunnel capability is associated with one or more phase II tunnels associated with the VPN. Traffic generated by the peer is detected, and if traffic is detected at a tunnel, the tunnel is presumed to be alive. When no traffic is detected in a tunnel, a DPD packet exchange with the tunnel is initiated. A determination is made, based on the packet exchange, whether the tunnel is alive. | 07-09-2015 |

20110241550 | Inrush Current Protection - Methods of protecting an electrical device, such as a ballast, from damage due to an inrush current, and devices incorporating such methods, are disclosed. A loss of input power received by the ballast is detected. In response, the ballast is entered into a standby mode. The ballast is able to remain in the standby mode for a standby period of time. The input power is monitored during the standby period of time to measure a start time. Measurement of the start time is triggered by the ballast receiving input power again. The ballast is entered into an active mode when the measured start time exceeds a protection time. The protection time corresponds to an amount of time needed for an inrush current to dissipate following input power again being received by the ballast, protecting the ballast from possible damage due to the inrush current. | 10-06-2011 |
