Dimensioning of NGN Main Components with Improved and Guaranteed Quality of Service

In this paper, we propose a set of dimensioning rules, which deliver high quality session-based services over an NGN networks based IP/MPLS transport infrastructure. In particular, we develop a detailed dimensioning methodology for achieving a target QoS requirement, expressed in terms of per-service traffic flow throughput and delay. One of the benefits of the proposed methodology lies in outlining an optimal equipment allocation strategy for a requested capacity. We explore the benefits of operating a network under the paradigm of generous dimensioning, for converged multiservice traffic flows which include target QoS guarantee, scalability, and resilience of the transport network, while maintaining high resource management. We also present and discuss experimental results which illustrate a practical implementation of the proposed dimensioning strategy and its benefits.
