What is the best method to communicate with multiple PCs

[Arvind_Soliton]

A server machine should start an application in multiple PCs and once they are done, the client should report the server machine that the process is done and pass the results, though they are not big. What is the efficient method to communicate with multiple PCs, that would,

1. reduce the server process to wait polling for the client machines to respond

2. be sure that all the data generated at the client is transfered to the Server.

TCP/IP is a good solution.
