The PIRR Methodology to Estimate Resource Requirements for Distributed NM Applications in Mobile Networks

Abstract

The current centralized Network Management approach in mobile networks may lead to problems with being able to scale up when new customer services and network nodes will be deployed in the network. The next generation mobile networks proposed by 3rd Generation Partnership Project (3GPP) envision a flat network architecture comprising some thousands of network nodes, each of which will need to be managed, in a timely and efficient fashion. This consideration has prompted a research activity to find alternative application architectures that could overcome the limits of the current centralized approaches.
