Multi-path transmission

using several paths between the source and the destination

will cause packet reordering and present some problems about load balancing while achieving high bandwidth utilization.This paper proposes a traffic splitting algorithm based on nonius.We define the nonius as the deference between the transmission delay of the current path and the time between two successive packets.As a baseline of the delay

the nonius prevents the flow from packet reordering.The nonius can slide dynamically because of different path or the different time between two successive packets.The packet can be transmitted among as many paths as possible because the nonius slides dynamically;as a result

the load balancing can be achieved.The simulation results show that the proposed algorithm gains a prominent improvement in load balancing over previous algorithms

while without reordering is ensured.
