A transmission system, having a plurality of delivery server side routers which communicate with a plurality of delivery servers for delivering a content; and a client side router which communicates with a client device for receiving the content, is configured to include: a database for storing server load states of the plurality of delivery servers, and respective individual link load states for a plurality of delivery paths between the plurality of delivery server side routers and the client side router; and a path control unit for determining a minimum load state delivery path having a minimum load state among the plurality of delivery paths, based on sums of the server load states and the respective individual link load states stored in the database.

Transmission system, delivery path controller, load information collecting device, and delivery path controlling method

Included are a network information database for storing the statistical information collected from a router, a user request processing unit for accepting and processing a flow forwarding request from a user terminal connected to the network, a route control unit for searching for a route corresponding to the request from the user terminal by referring to the network information database, a load sharing control unit for executing such a load sharing process as to generate router setting information for sharing a transmission load of the network by referring to the network information database, and a router control unit for setting a router based on the route information determined by the route control unit and on the router setting information generated by the load sharing control unit.
