Study On A Policy-Based Resource Allocation Technology Of Communication Grid

Grid is regarded as the third generation of Internet. It is a new computing infrastructure, which integrates the computers of different location into a super computer through Internet. This can achieve the thorough share and collaboration of computing, storing, information, communication resource and so on.In this paper, through combining the grid services and policy-based resource allocation technology, a policy-based resource allocation technology, which can be run as a service in communication grid, is proposed based on the concept of grid. By configuring different policies, this service is able to optimize the allocation of network resources and improve their utilization efficiency under the condition that the QoS requirements of services are satisfied. Through proper coordinating and transformation the requirements such as the different QoS characteristics of different traffics and the customers'safety degree, the content of policy is formed and it is wrote in a file. According to the characteristic of the business services, policy-based resource allocation technology inquires related policy, computing and determines whether the related policy would be executed, and finally translates the policy into specific instructions to accomplish the operations such as resource allocation. Meanwhile according to requirements network manager could modify the policy file within a certain range, so this could implement different policies without modifying program files.The experiment results show that according to many-sides factors such as the QoS requirements of business services and customers'safety and reliability demands, this grid service could realizes network resource allocation and management.
