A study on resource granularity of vEPC optimal resource assignment

Abstract

In this paper, we study a resource granularity effect on the optimal resource assignment of MME and S/P-GW in a single vEPC server. We distinguished communications of M2M devices and smartphones and modeled the vEPC server by using queueing theory. Numerical analysis under a fixed number of hardware resources of MME and S/P-GW is done for various resource granularities of the vEPC server. The evaluation results of numerical analysis showed that the vEPC-ORA method derives the optimal resource assignment in a practical calculation time.
