Systems and methods optimizing backhaul transport

摘要

Systems and methods optimizing backhaul transport with respect to communication systems through the use of a heterogeneous backhaul link configuration and corresponding implementation of backhaul link path selection control to provide traffic offloading for traffic congestion mitigation are disclosed. Heterogeneous backhaul link configurations may include one or more backhaul links implementing a plurality of data paths providing different capabilities, such as may comprise a high reliability path and an unpredictable reliability path. Backhaul link path selection control of embodiments implements logic for determining when data is to be carried via one or more of the backhaul link paths.

1. A method comprising:
communicating a plurality of data flows over a high reliability path of a heterogeneous backhaul link, wherein the heterogeneous backhaul link comprises the high reliability path and an unpredictable reliability path, wherein the heterogeneous backhaul link is provided by a point-to-multipoint backhaul transport configuration, the point-to-multipoint backhaul transport configuration including the heterogeneous backhaul link providing a multiple path backhaul link and at least one other backhaul link having a high reliability path sharing a resource with the high reliability path of the heterogeneous backhaul link, and wherein the plurality of data flows include one or more high priority data flow and one or more low priority data flow; detecting congestion with respect to communication over the high reliability path of the heterogeneous backhaul link; determining a backhaul link associated with the congestion; analyzing quality of the unpredictable reliability path; and offloading of one or more data flow based at least in part on the backhaul link associated with the congestion, the quality of the unpredictable reliability path, and priority of the one or more data flow, wherein the offloading is controlled such that at least a portion of the one or more low priority data flow carried by the high reliability path of the heterogeneous backhaul link is offloaded from the high reliability path to the unpredictable reliability path and at least a portion of the one or more high priority data flow continue to be communicated via the high reliability path after the offloading when the at least one other backhaul link is determined to be associated with the congestion and the quality of the unpredictable reliability path is high.
