In order to utilize the resources of all nodes in networks fully

a novel conjunct model of cloud ＆ client computing based on multi-agent was proposed

dividing the computing environment into three layers in accordance with the type of node and adopting agent to represent the behavior and resource of node to realize more efficient resource sharing and collaboration.The model takes full account of available resources owned by terminal nodes and deploys tasks in an orderly manner to the core nodes

servers and terminal nodes in order to maximize the efficiency of the resource utilization.To assure that tasks could be completed efficiently and reliably

a multi-agent-based collaborative multi-ring management mechanism was also presented

which is particularly suitable for the cloud ＆ client conjunct computing environment and propitious to enhance the stability of resources sharing and nodes cooperation and relieve the load of core nodes.Finally

the construction method of experimental system and application demonstration based on the model was provided for reference.
