Abstract
A communication device belonging to a first cluster among a plurality of clusters includes a memory, a processor, and a network connection device. The memory stores identification information of another cluster that has information being retrievable by a terminal connecting to the communication device in a summary of data held by the other cluster. The processor performs, upon receiving a combination of identification information of a second cluster that holds retrieval-target data and identification information of the retrieval-target data from the terminal that accessed the summary, a control to request target data identified by the combination. The network connection device forwards the target data to the terminal.
Claims7
A non-transitory computer-readable recording medium having stored therein a communication program that causes a computer, of a communication device belonging to a first cluster among clusters that include a plurality of communication devices, to execute a process comprising:
- storing a summary of metadata including attribute of data held by a terminal connected to a communication device belonging to another cluster that is different from the first cluster, the summary including, as the attribute, a word extracted from a description of the data, the description being included in the metadata;
- forwarding the summary to another communication device belonging to the first cluster;
- upon receiving a request to retrieve metadata based on the summary, retrieving the metadata from the communication device belonging to the another cluster and forwarding the retrieved metadata to a source that made the request to retrieve the metadata;
- receiving, from another terminal connected to the communication device belonging to the first cluster, an inquiry for a cluster that holds data retrievable by the another terminal;
- identifying, in the summary, information that the computer has determined to be associated with the data retrievable by the another terminal;
- and
- transmitting the identified information to the another terminal.
A communication device belonging to a first cluster among clusters that include a plurality of communication devices, the communication device comprising:
- a memory configured to store a summary of metadata including attribute of data held by a terminal connected to a communication device belonging to another cluster that is different from the first cluster, the summary including, as the attribute, a word extracted from a description of the data, the description being included in the metadata;
- and
- a network connection device connected to a network which is the first cluster and configured to forward the summary to another communication device belonging to the first cluster, wherein
- the network connection device, upon receiving a request to retrieve metadata based on the summary, retrieves the metadata from the communication device belonging to the another cluster and forwards the retrieved metadata to a source that made the request to retrieve the metadata, and
- the network connection device
- receives, from another terminal connected to the communication device belonging to the first cluster, an inquiry for a cluster that holds data retrievable by the another terminal,
- identifies, in the summary, information that the communication device belonging to the first cluster has determined to be associated with the data retrievable by the another terminal, and
- transmits the identified information to the another terminal.
A communication method for a communication device belonging to a first cluster among clusters including a plurality of communication devices, the method comprising:
- storing a summary of metadata including attribute of data held by a terminal connected to a communication device belonging to another cluster that is different from the first cluster, the summary including, as the attribute, a word extracted from a description of the data, the description being included in the metadata;
- forwarding the summary to another communication device belonging to the first cluster;
- upon receiving a request to retrieve metadata based on the summary, retrieving the metadata from the communication device belonging to the another cluster and forwarding the retrieved metadata to a source that made the request to retrieve the metadata;
- receiving, from another terminal connected to the communication device belonging to the first cluster, an inquiry for a cluster that holds data retrievable by the another terminal;
- identifying, in the summary, information that the communication device belonging to the first cluster has determined to be associated with the data retrievable by the another terminal;
- and
- transmitting the identified information to the another terminal.
