An effect of combining CDN with reactive in-network guidance method

These days, server load has been increasing because of various factors such as larger content size and flash crowd. Content Delivery Network (CDN) is widely used to deal with this problem. In CDN, replica servers are placed dispersedly in all over the Internet to achieve high QoS content delivery. On the other hand, Breadcrumbs (BC) method is proposed to implement content-oriented network framework on the conventional IP network. BC is a guidance information which is created in routers to utilize user´s cache. In this paper, we operate CDN and BC framework together on IP network to improve the performance on content retrieval and acquisition. Finally, we make a CDN model and evaluate the coexisting approach through simulation. Simulation results show that our approach can greatly reduce server load.
