Interface selection in a hybrid communication device

摘要

A hybrid device can be configured to select a transmit interface to attempt to ensure that each network interface of the hybrid device supports unidirectional traffic. Each of the plurality of network interfaces of the hybrid device can be categorized into one of a set of interface classes based on whether incoming traffic is received at the network interface and/or whether outgoing traffic is transmitted from the network interface. A transmit interface class is selected from the set of interface classes based, at least in part, on a priority level associated with each of the interface classes. One of the network interfaces that belongs to the transmit interface class is selected as a transmit interface for transmitting the frame on the communication network.

1. A method performed by a first network device, the method comprising:
classifying each network interface of a plurality of network interfaces associated with the first network device into at least one of a plurality of interface classes based, at least in part, on whether the network interface has transmitted or received a communication within a time interval; selecting one of the plurality of interface classes as a transmit class based, at least in part, on a priority level associated with each of the plurality of interface classes; selecting one of the plurality of network interfaces of the transmit class as a first transmit interface, wherein a second network device is reachable via the first transmit interface; and transmitting a first frame from the first network device to the second network device via the first transmit interface.
