Abstract

A method of conducting a connectionless communication in a network communication system including a client, a server, and a plurality of proxy servers which are disposed on a transmission path between the client and server. The communication is accomplished by use of specification of a communication address thereof and a port number dynamically assigned by the computer. (a) The server transmits own communication address and own port number to the client. (b) The client transmits own communication address and own port number as well as the communication address and port number of the server to a first adjacent proxy server computer. (c) The N-th (N.gtoreq.1) proxy server transmits own communication address and own server side port number as well as the communication address and the port number of the server to an (N+1)-st proxy server. (d) step (e) is repeatedly executed by incrementally increasing N until the (N+1)-th proxy server becomes a terminal proxy server. (e) The terminal proxy server transmits its own communication address and its server and client side port numbers to the N-th proxy server. (f) The N-th proxy server sends own communication address and own client side port number and the communication address and the server side port number of the terminal proxy server to the (N-1)-th proxy server when N.gtoreq.2 or the client when N=1. (g) step (f) is repeatedly executed by incrementally increasing N until N becomes one. (h) The client transmits a communication address and a server side port number of the proxy server to the server. (i) The connectionless communication is commenced after all computers acquire a communication address and an associated port number of each of the computers adjacent thereto.
