METHOD FOR SETTING AND CONTROL OF ROUTE IN NETWORK AND ACTIVE ROUTER

PROBLEM TO BE SOLVED: To provide a route-setting method, in which an active router can be introduced by a method where a control node used for controlling or distributing position information, route information or the like on the active router is not set inside a network. SOLUTION: In the route-setting method between terminals in the network, a structure in which a plurality of nodes comprising a packet transfer function are connected in a route is formed, a part of the plurality of nodes is constituted of active routers comprising a prescribed processing function together with the packet transfer function, and the transfer rule of a packet relay node in a terminal communication is predetermined. The packet from a terminal 1 is transferred to a terminal 2 via the respective nodes inside the network according to the predetermined transfer rule, the active routers which are to transfer the packet to the terminal 1 from the terminal 2 are decided, on the basis of the order of the active routers which relay the packet in its process, and the transfer route of the packet to the terminal 1 from the terminal 2 is set.
