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.
