Description
Summary: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.
