Abstract
In accordance with an embodiment, a network device includes a network controller and at least one network interface coupled to the network controller that includes at least one media access control (MAC) device configured to be coupled to at least one physical layer interface (PHY). The network controller may be configured to determine a network path comprising the at least one network interface that has a lowest power consumption and minimum security attributes of available media types coupled to the at least one PHY.
Claims20
A method of operating a network device comprising a first data interface and a plurality of network interfaces, the method comprising:
- determining a network path comprising at least one of the plurality of network interfaces that has a lowest power consumption and appropriate security requirements of available media types, wherein the determining the network path comprises using a hardware-based controller, wherein the determining the network path comprises:
- determining a first set of security requirements for transmitting a first message on the network path;
- and
- determining a second set of security requirements for transmitting an acknowledgment to the first message, the second set of security requirements being different than the first set of security requirements;
- and
- determining over which of the plurality of network interfaces the first data interface sends data to and receives data from, based on the determined network path, wherein the determining over which of the plurality of network interfaces the first data interface sends data to and receives data from comprises using the hardware-based controller.
