The invention discloses a routing implementing method comprising steps of calculating the routing cost between each node of a network and the exit node of the network; comparing the routing cost of a local node of neighbor nodes thereof; using the neighbor node having the routing cost smaller than that of the local node as the next-hop routing node of the local node; generating a routing from the local node through the neighbor node having the routing cost smaller than that of the local node to the exit node of the network. According to the invention, all the passable links can participate in the data forwarding process, more routings for reaching the destination can be provided and the network transmission efficiency is improved. The invention provides a large amount of available resources to the routing and sets the stage for the realization of whole-network load balancing. The multiple next-hops generating algorithm provided in the invention has a simple operation and a low communication traffic.
