An Analysis of Policy Provisioning Complexity in Accordance with the Application Attributes of the Policy-Based Network

摘要

Since policy-based network technologies emerged themselves, a number of policy-based applications have been tried in the field of communications, which are just independent applications in accordance with policy-based management by each area. Particularly, lots of them were concerned with security and QoS areas. A single policy claims the control of network resources according to relations between network state and its application demand. We attempted to model and evaluate the effect of policy-based applications which were independently applicable to each area on network resources. For the purpose, we defined the complexity, dynamic property and globalization of policy as a matrix affecting its applications, including parameters with influences upon each matrix. Our evaluation results suggest that, in designing a policy-based network, there must be construction factors carefully considered according to their application attributes.
