Abstract
A network interface controller of a computing device is disclosed that processes network packets without waking the computing device. The network interface controller may detect that a secured connection with an access point has been disconnected and may reconnect to the access point without waking the computing device. The network interface controller may support roaming between access points without waking the computing device. The network interface controller may also support establishing, re-establishing and maintaining a secured session with another computing device while a computing device is in a sleep state.
Claims30
A method comprising
- placing a computing device in a sleep state,
- receiving one or more network packets while the computing device is in a sleep state, and
- responding to the one or more network packets without waking the computing device from the sleep state.
A machine readable medium comprising a plurality of instructions that in response to being executed, result in a network interface controller of a computing device
- detecting a wireless connection with an access point has been disconnected while the computing device is in a sleep state, and
- re-establishing the wireless connection with the access point without waking the computing device from the sleep state.
A computing device, comprising
- memory to store instructions including instructions associated with establishing a secured session with another computing device on a network,
- a processor to execute the instructions stored in the memory, and
- a network interface controller to send and receive signals to and from the network, and to establish the secured session with the another computing device on the network without waking the processor from a sleep state.
