In many regions, multiple technologies or network operators are available to provide mobile data access. Bonding multiple of these transmission paths to a single, virtual data link, oers the potential to increase achievable data rates or reliability. Due to the prevalent usage of TCP for data transmission, multi-path scheduling algorithms need to be carefully designed in order to not interfere with its congestion avoidance. In this thesis, a scheduling algorithm based on packet-train throughput estimations is presented and evaluated in a simulation scenario with dynamically changing channel characteristics. It has shown to be capable of aggregating data rates of multiple interfaces while guaranteeing in-order delivery of packets. Further research is, however, necessary in order to minimize drop rates resulting from this guarantee.
