Confirmed delivery of bridged unicast frames

摘要

Systems and methods to reduce table lookups and network traffic are provided. A bridging device may receive a unicast frame to be bridged. The unicast frame may be transmitted to at least one network of a plurality of networks. The bridging device may determine if the unicast frame was successfully delivered to the at least one network.

1. A method to reduce table lookups and network traffic when bridging networks, the method comprising:
receiving, at a bridging device, a unicast frame to be bridged; transmitting the unicast frame by the bridging device without using an address table to one of a plurality of confirmed delivery networks and determining, at the bridging device, whether the unicast frame was successfully delivered; preventing the unicast frame from being retransmitted to another network of the plurality of confirmed delivery networks in response to determining that the unicast frame was successfully delivered to the one confirmed delivery network; sequentially transmitting the unicast frame to one or more other networks of the plurality of confirmed delivery networks when the bridging device determines that the unicast frame was not successfully delivered to the one confirmed delivery network; and transmitting the unicast frame to one of a plurality of non-confirmed delivery networks when the bridging device determines that the unicast frame was not successfully delivered to any of the confirmed delivery networks.
