As an important technology to optimize the allocation of resources and load balancing,multipath routing has advantage of reliability in routing,QoS routing,transmission efficiency and other aspects than single path.The current Internet architecture and mechanisms have a low resource utilization,poor network security,poor scalability,and high-energy consumption,which is not conducive to the advancement of multipath.Meanwhile,the disadvantage of the current multipath techniques was the path selection and calculation.Multipath algorithm only chose the path considering the network performance and parameters limitedly,which may choose the congestion path.In this paper,we proposed a multi-parameter multipath routing protocol of smart and cooperative networks,and analyzed the flow distribution by the graph theory.We distributed the flow by the path weight,and the weight was determined by CPU utilization,RTT and bandwidth.We developed and experimented the algorithm on the Mini-Net,and the simulations revealed that the algorithm could achieve wisdom together the multipath data transmission function of the network,and ensure transmission performance of the chosen flow distribution.In addition,it was easy to implement,effective to save the network resources and optimized the network configuration,improved the efficiency of network transmission.
