Step 502, the service provision grid node --- the service domain owner
and administrator builds up an instance of the service provision grid node:
The service provision grid node delivers the property information of the
service content to the service administration grid node;
Step 503, the service provision grid node decomposes the service
provision instance --- the service provision grid node provides service:
The service provision grid node will await and respond to the service
request of the service request grid node, which is forwarded from the service
administration grid node. The service provision grid node processes the
io information relating to the service content property and handles fee
calculation.
Step 504, check resources:
After receiving the service request of the service request grid node, which
is forwarded from the service administration grid node, the service provision
grid node checks the service resources.
Step 505, check the user's key and the ID of the service request grid
node:
The service provision grid node checks the user's key and the ID of the
service request grid node according to the service request of the service
request grid node, which is forwarded from the service administration grid
node.
Step 506, service resources check:
The service provision grid node decomposes the service request of the
service request grid node, acquiring the request of service content, and
