A dynamic traffic distribution strategy for multipath routing

It has been widely recognized that the multipath routing can be fundamentally more efficient than the traditional approach of routing along single path. A self-adaptive traffic splitting algorithm, called Dynamic Weighted Round-Robin (DWRR), has been developed to distribute traffic fairly in term of the weight so as to obtain good performance of network load balance. In addition, DWRR can get lower end-to-end delay in multipath routing and may adapt to the path state to reduce the congestion. Result obtained from the simulations shows that DWRR is efficient in maintaining network load balance and gets high performance in reducing the end-to-end delay.
