Abstract

In this paper, we analysis content distribution method for Content Delivery Networks. It is necessary to manage content distribution differentially based on its characteristic. To address this issue, we explained origin server capability with multi-priority service and revenue concept. For including the aspect of operational revenue, we define a performance index with the terms 'plus' and 'minus' respectively according to whether a service request is successfully conducted or not. For the numerical analysis, we show that origin server can be modeled as M/M/m/m, investigate how it is differentiated compared with FCFS based distribution policy as the aspect of performance index.
