摘要： A parameter setting change method for a system that performs multicast distribution from an information distribution apparatus to a plurality of mobile stations via a relay node is provided. In the method, a parameter adjustment setting apparatus analyzes a data reception state output from the plurality of mobile stations and calculates an information-distribution-apparatus setting-change parameter and a relay-node setting-change parameter for making the data reception state within a predetermined range. Then, when the information distribution apparatus can be set to the information-distribution-apparatus setting-change parameter, the relay node performs setting change to the relay-node setting-change parameter.

摘要： A routing apparatus comprises a resource management unit holding resource management information for managing a state of use of a communication resource in another routing apparatus that can be an adjacent routing apparatus transferred a packet data. When packet data for a reservation request is received, a determining unit determines the adjacent routing apparatus on the basis of destination information given to the packet data and the resource management information in the resource management unit to control a routing (packet transfer). A routing process at the time of reception of a request for reserving a resource (communication resource) is performed in consideration of a state of use of a resource in the adjacent routing apparatus, thereby preventing a wasteful routing at the time of resource reservation.
