System and method for selecting a transmission medium on which to transmit a first stream. At least one of the plurality of transmission media may be substantially dynamic in nature. Path characteristics of each of a plurality of transmission media may be determined. A first transmission medium may be selected from the plurality of transmission media for the first stream based on the determined path characteristics. A first plurality of packets of the first stream may be transmitted on the first transmission medium.

Hybrid networking path selection and load balancing

A coordinated back-off mechanism for automatic path selection for minimizing race conditions in hybrid communication networks is disclosed. A network device determines a stream medium utilization associated with packet streams for each priority class and network interface of a plurality of communication devices (including the network device). For each priority class and network interface, the communication devices are ranked according to the stream medium utilization. In response to determining that a medium utilization of a network interface exceeds a corresponding medium utilization threshold, the network device determines whether one of its network interfaces originates a packet stream with the greatest stream medium utilization value for a selected priority class. If so, path selection operations are executed to reduce the medium utilization associated with network interface below the medium utilization threshold. Otherwise, a back-off period is calculated based on the ranking associated with the network device for the selected priority class.

Coordinated back-off mechanism for path selection in hybrid communication networks

A hybrid network device can implement functionality for automatic path selection and modification in a hybrid communication network. The hybrid network device can select an initial network interface from a plurality of network interfaces for transmitting a packet stream. In response to determining that the medium utilization of the initial network interface exceeds the medium utilization threshold, the hybrid network device can identify one or more packet streams originating from the initial network interface to shift to corresponding one or more alternate network interfaces. The hybrid network device can attempt to reduce the medium utilization of the initial network interface below the medium utilization threshold while maintaining the medium utilization of the one or more alternate network interfaces below the corresponding medium utilization thresholds. The hybrid network device can shift the one or more packet streams from the initial network interface to the corresponding one or more alternate network interfaces.

Automatic path selection for hybrid communication networks

Communicating between stations over a shared medium includes: monitoring the shared medium for signals received at a first station that is identified with a local network; storing information at the first station that represents characteristics of the signals received at the first station associated with capacity of the shared medium; monitoring the shared medium for signals received at a second station that is identified with the same local network as the first station; storing information at the second station that represents characteristics of the signals received at the second station associated with capacity of the shared medium; and determining whether a stream of data is allowed to be transmitted over the shared medium between the first station and the second station based on at least one of the stored information from the first station and the stored information from the second station.
