A system for establishing a communication path in a closely coupled computer system

摘要

In a system for establishing a communication path between one global server (13) and a plurality of local servers (14,14′) and transmitting a request for processing a message through the communication path in a closely coupled computer system (10), the establishing system includes: a first capability (C-CAP) which is issued from the global server (13) or the local server (14,14′) to an arbitrary client to receive the request transmitted from the arbitrary client; a second capability (R-CAP) which is issued from the global server (13) or local server (14,14′) to a specified server to establish the communication path ensuring security of the message from the specified server; a message communication unit (12) for transmitting the message between the global server (13) and the local server (14,14′) by using the first and second capability (C-CAP,R-CAP); and a destination intermediation unit (11) for registering the first capability (C-CAP) and informing the first capability to the local server (14) to intermediate the communication between the global server (13) and the local server (14); wherein the global server (13) requests the registration of the first capability (C-CAP) from the destination intermediation unit (11), the local server (14,14′) acquires the first capability (C-CAP) from the destination intermediation unit (11), and the local server (14,14′) requests the establishment of the communication path (12) from the local server (14,14′) to the global server (13) by using the second capability (R-CAP).
