Abstract

Abstract 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).

Claims Analysis

Total Claims: 6

Claim 1

Independent Claim 208 words

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 establishing system comprising; 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 a request transmitted from the arbitrary client; a second capability (R-CAP) which is issued from the global server or local server to a specified server to establish a communication path ensuring security of a message from the specified server; message communication means (12) for transmitting the message between the global server and the local server by using the first and second capability; and destination intermediation means (11) 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; wherein the global server requests the registration of the first capability from the destination intermediation means, the local server acquires the first capability from the destination intermediation means, and the local server requests the establishment of the communication path from the local server to the global server by using the second capability.

Claim 2

Dependent Claim 64 words

A system for establishing a communication path as claimed in claim 1, further comprising a reception server (15) for receiving a request from a client (50) which wishes to use a resource, the global server (13) transmitting a capability to the reception server, and the capability indicating the destination of a volume file transmitted from the local server and corresponding to the volume file.

Claim 3

Dependent Claim 80 words

A system for establishing a communication path as claimed in claim 2, wherein the reception server comprises management means (15a) for managing the name of the volume and the capability transmitted from the global server, volume name deriving means (15b) for deriving the corresponding volume name from the resource indicated by the client, and destination data acquisition means for acquiring the corresponding capability by searching the management means based on the volume name derived from the volume name deriving means.

Claim 4

Independent Claim 37 words

A system for establishing a communication path as claimed in any preceding claim, wherein said destination intermediation means (11) comprises a control table (11a) constituted by the name of the server and the destination of the server.

Claim 5

Independent Claim 36 words

A system for establishing a communication path as claimed in any preceding claim, wherein said global server (13) comprises a control table constituted by the name of the server and the destination of the local server.

Claim 6

Independent Claim 37 words

A system for establishing a communication path as claimed in any one of claims 2 to 5, wherein said reception server further comprises a plurality of R-CAP management tables for managing the volume name and the capability.
