Patent Images
1. A cluster system comprising:
- a transmission side server cluster consisting of a plurality of computers;
a receiving side server cluster consisting of a plurality of computers; and
a network that interconnects both said transmission side server cluster and said receiving side server cluster, wherein one computer which is included in said transmission side server cluster and has received a message (which is hereinafter referred to as a “
transmitting computer”
) selects a second computer (hereinafter referred to as a “
standby computer”
) from among the computers in said transmission side server cluster, based on load information, and transmits the received message to said standby computer when transmitting the message to a receiving side server.

Abstract
A cluster system includes a transmission side server cluster consisting of a plurality of computers, one of which is selected as a transmitting computer and at least another one of which is selected as a standby computer. When the transmitting computer transmits a message it received to a receiving side server, it also transmits the message to the standby computer that was selected, based on load information for all computers other than the transmitting one in the transmission side server cluster.

14. A cluster system comprising:
-
a first computer cluster which receives a message from an external device;
a second compute cluster which receives the message from said first computer cluster; and
a third computer cluster which receives the message from said second compute cluster, wherein a computer which is included in said first computer cluster and receives the message (which is hereinafter referred to as a “
first transmitting computer”
) selects a computer (hereinafter referred to as a “
first standby computer”
) from said first computer cluster, based on load information for every computer included in said first computer cluster,wherein said first transmitting computer transmits the message to said first standby computer when transmitting the message to said second computer cluster, wherein a computer which is included in said second computer cluster and receives the message (which is hereinafter referred to as a “
second transmitting computer”
) selects a computer (hereinafter referred to as a “
second standby computer”
) from said second computer cluster, based on load information for every computer included in said second computer cluster, andwherein said second transmitting computer transmits the message to said second standby computer when transmitting the message to said third computer cluster. - View Dependent Claims (15, 16, 17, 18)
