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 min ) 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 min ) 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 min ) 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 min ) 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 min ) acquires the first capability (C-CAP) from the destination intermediation unit (11), and the local server (14,14 min ) requests the establishment of the communication path (12) from the local server (14,14 min ) to the global server (13) by using the second capability (R-CAP).
