Abstract: A multivolume management method, executed by a computer, includes storing a dataset over a plurality of media storage devices, wherein the plurality of media storage devices has a corresponding plurality of physical identifiers, generating a conversion table that assigns the plurality of physical identifiers to a corresponding plurality of sequentially ordered virtual identifiers, wherein each physical identifier is uniquely assigned to one virtual identifier, receiving a request for the dataset, wherein the request references the plurality of sequentially ordered virtual identifiers, in response to receiving the request, generating a response comprising an ordered list of physical identifiers using the conversion table, and responding to the request with the response. A computer system and computer program product corresponding to the above method are also disclosed herein.

Abstract: In a communication control method and a mobile terminal it is possible to realize multi-hop communication having three or more hops in a routing system based on a star-type network connection topology which is more efficient than conventional table drive-type and storage transfer-type routings. An operation of relaying transfer data stored within a mobile terminal before the dissolution of s group to a mobile terminal which newly becomes a group fellow from the outside of the group is repeated any number of times by the repeated execution of the dissolution/reconfiguration of the group. Consequently, it is possible to realize multi-hop communication for relaying and transferring the transfer data even if the upper limit (two hops) of the number of relay hops in a star connection-type system is exceeded.
