QoS Modeling and Analysis in 5G Backhaul Networks

Huge efforts are being spent by industry and research institutes for the standardization and preparation of introducing 5G mobile networks that are required to serve user needs. Consequently, a new architecture for different applications is needed for solving the issues related to high data rate, capacity, reliability, and ensuring QoS. In addition, the 5G infrastructures shall provide tailored network solutions specialized to support vertical markets. For such applications, the QoS provided by the network can be critical, thus its analysis is inevitable. This paper presents a model to be applied in QoS analysis and to consider options for the flexibility which shall come with 5G. The model is developed to study the migration of backhaul architecture to 5G, and its effects on the fulfillment of QoS requirements. We performed a case study based on priority-aware queueing analysis, that shows some advantages and issues of this migration.
