Transmission of data in a distributed data processing computer system

A server, comprising:

• at least one processor;
• a server data storage;
• and
• a memory, the memory storing a computer executable code, the computer executable code when executed by the at least one processor causing the server to,
• store, on the server data storage,
• a plurality of storage policies associated with information data items on local data storages of a plurality of end terminals,
• connectivity information for establishing respective connections to each of the end terminals of the plurality of end terminals, and
• a plurality of descriptions of the information data items stored on the local data storages,
• establish a first end terminal-server connection between the server and a first end terminal of the plurality of end terminals,
• receive a data request from the first end terminal via the established first end terminal-server connection,
• terminate the established first end terminal-server connection after receiving the data request,
• query the server data storage to identify whether one or more information data items are available on a local data storage of a second end terminal of the plurality of end terminals for generation of a requested information data item according to the data request, according to respective storage policies of the plurality of storage policies associated with the one or more information data items,
• generate a connectivity data item including connectivity information for establishing an end terminal-end terminal connection to the second end terminal when the one or more information data items are identified as available on the local data storage of a second end terminal of the plurality of end terminals,
• reestablish the first end terminal-server connection,
• send the connectivity data item to the first end terminal via the reestablished first end terminal-server connection,
• terminate the reestablished first end terminal-server connection after the connectivity data item is sent,
• establish a second end terminal-server connection between the first end terminal and the server,
• receive the data request from the first end terminal via the established second end terminal-server connection for the second time,
• terminate the established second end terminal-server connection after the data request is received for the second time,
• generate the requested information data item according to the data request received for the second time,
• reestablish the second end terminal-server connection,
• send to the first end terminal via the reestablished second end terminal-server connection the requested information data item generated by the server according to the data request received for the second time, and
• terminate the reestablished second end terminal-server connection after the requested information data item is sent to the first end terminal,
• wherein the server is configured to process data requests repeatedly sent to the server with higher priority than data requests sent to the server for the first time, the first end terminal is configured to send the data request for the second time to the server in response to failure of,
• establishing a respective end terminal-end terminal connection using a respective connectivity data item downloaded from the server, or
• generating, by the second end terminal, the requested information data item within a maximum time interval.

A first end terminal, comprising:

• at least one processor;
• and
• a memory, the memory storing a computer executable code, the computer executable code, when executed by the at least one processor causing the first end terminal to,
• establish an end terminal-server connection between the first end terminal and a server,
• send a data request to the server,
• terminate the established end terminal-server connection after the data request is sent,
• reestablish the end terminal-server connection,
• download a connectivity data item from the server via the reestablished end terminal-server connection when a requested information data item can be generated on a second end terminal using one or more information data items stored on a local data storage of the second end terminal according to the data request, the connectivity data item being generated by the server in response to receiving the data request, the connectivity data item including connectivity information for establishing a connection to the second end terminal,
• terminate the reestablished end terminal-server connection after the connectivity data item is downloaded,
• establish an end terminal-end terminal connection between the first end terminal and the second end terminal using the connectivity information in response to downloading the connectivity data item,
• process the data request on the second end terminal by,
• sending the data request to the second end terminal via the established end terminal-end terminal connection,
• causing the second end terminal to generate the requested information data item according to the data request via the established end terminal-end terminal connection, the second end terminal generating the requested information data item using the one or more information data items stored on the local data storage of the second end terminal, and
• downloading the generated requested information data item from the second end terminal via the established end terminal-end terminal connection, and
• terminate the established end terminal-end terminal connection after the downloading the generated requested information data item, wherein the causing includes,
• sending a maximum time interval for the generation of the requested information data item to the second end terminal, and
• reconfiguring the second end terminal to make it operable for the generation of the requested information data item according to the data request within the maximum time interval.
