Abstract

In a system for establishing a communication path between one global server and a plurality of local servers and transmitting a request for processing a message through the communication path in a closely coupled computer system, the system includes, a first capability which is issued from the global server or the local server to an arbitrary client to receive the request transmitted from the arbitrary client, a second capability which is issued from the global server or local server to a specified server to establish the communication path ensuring security of the message from the specified server, and a message communication unit for transmitting the message between the global server and the local server by using the first and second capability. The system also includes a destination intermediation unit for registering the first capability and informing the first capability to the local server to intermediate the communication between the global server and the local server. During operation of the system, the global server requests the registration of the first capability from the destination intermediation unit, the local server acquires the first capability from the destination intermediation unit, and the local server requests the establishment of the communication path from the local server to the global server by using the second capability.
