Abstract: It is possible to improve backhaul resource utilization efficiency during dynamic point selection (DPS) transmissions by unicasting different portions of a traffic flow to different access points participating in the DPS transmission. Specifically, a traffic flow may be encoded to obtain forward error correction (FEC) packets, and different subsets of the FEC packets may be unicast to different access points participating in the DPS transmission. The subsets of FEC packets may have partial (or no) redundancy such that the amount of duplicative data communicated over the backhaul network is reduced when compared to multicasting the entire traffic flow to each access point participating in the DPS transmission. There may be different degrees of redundancy between subsets of FEC packets to achieve different traffic engineering (TE) objectives.

Abstract: In a networked multi computer environment with redundant links, network interface cards (NICs) are commonly duplicated and teamed to provide a recovery mechanism when network components fail. Embodiments of the present inventions avoid teaming of pairs of NICs and provide a computing host with redundant network connections for the computing host through a switch that is transparent to the computing host. The computing host itself; that is, its hardware and software, is relieved of the duty of network access redundancy and returned to the simple, simplex networking operating mode. The switch replaces a potentially large number of NICs and the need for computing host network access redundancy management which leads to hardware and software cost reductions and increases the robustness and reliability of the system through redundant network access.
