Hybrid framework for scalable resource control in multi-ingress networks

Attempts by the research community to meet expectations arising from future Internet systems, and specifically to provide Quality of Service (QoS) for multimedia multi-user sessions, have resulted in mechanisms such as MultiUser Aggregated Resource Allocation (MARA). Its results have been promising, mainly because it drastically reduces signaling and processing overhead, despite its limitations in multi-ingress scenarios. In view of these benefits, this paper proposes the MultiUser Aggregated Resource Allocation - Multi-Ingress to overcome the main limitations of MARA so that it can serve as a promising tool in current and future IP-based network systems. The simulation experiments carried out for MARA-MI demonstrated the benefits in optimizing bandwidth use and networking costs while maintaining QoS over time in multiple sessions, in comparison to a relevant related work.
