1. In a data processing system wherein a plurality of program-controlled data processing systems are interconnected as nodes in a telecommunication network, at least one of said nodes including an input/output device, and wherein each node of the network is capable of processing data according to resources associated with that node by setting up and executing a transaction process in response to each particular data processing request and any related requests presented thereto, the combination of:

  • means at each node of the system for determining when a local data processing request involves a transaction that requires the use of a resource held at another node of the system,means at each node for transmitting the transaction request for the use of such a resource to the other node containing that resource,means at each of said nodes for receiving transaction requests from other nodes in the system and for presenting each received transaction request to the data processing system at the receiving node in the same manner as though such request had originated locally at that node, thereby enabling the local data processing system to perform the transaction process associated with a request from another node as it would perform a transaction process associated with a like request originated at the local node, andmeans at each of said nodes for transmitting the data resulting from said process to the requesting node.
