LTE CoS/QoS Harmonization Emulator

Abstract

There are many challenges in the QoS controls and traffic handling mechanisms in the deployment of Long Term Evolution (LTE). Simulations are crucial for performance evaluation of end-to-end QoS (Quality of Service) management across LTE network elements over heterogeneous networks. The LTE CoS/QoS Harmonization Emulator presented in this paper will allow the user to determine whether the QoS design strategy specifically and logically fits in a variety of LTE network topologies. The Emulator is capable of evaluating effectiveness of CoS/QoS mapping, performance of QoS controls (classification/policing/mark/queuing&dropping/ shaping) and traffic handling mechanisms that supports specific LTE applications. This module is portable and can be integrated with the performance management (PM) system as a part of business/operations impact analysis to support testing during the system development and quality assurance phases. The Emulator is offered for free under the terms of an academic, non-commercial use license.
