Network Resource Planning for Minimizing VRTT based on Cost Constraint

Estimating and building a reasonably sized and configured ICN network based on user needs is an important part of advancing the further implementation of ICN. Reasonable network resource planning can provide a reference for operators, give clients better use experience under certain costs. Research has so far studied planning methods for IP networks, and there is almost no method on ICN network planning. In this paper, we model the ICN network resource planning problem. We determine the optimization objectives and con-straints, improve the accuracy of the tree topology network model based on the Che approximation, and then obtain the approach to the planning problem. Simulation experiments show that our network planning approach can effectively reduce VRTT under cost constraints, as well as the improved model is more accurate.
