Abstract

In this paper, we describe an innovative queue management mechanism in order to achieve an optimal use of shared communication resources. The target scenario contemplates different data flows sharing the same network resources at the same time. The main challenge over this scenario is to achieve the required QoS (Quality of Service) to redistribute real-time and high constraints services. The described queue management algorithm, proposes an innovative queue utilization method based on the combination of the data flows to be redistributed, providing a more efficient use of the network resources, and inducing important improvements in the caused delay and jitter. Present work describes the design of a mechanism based on Network Coding that achieves new QoS up-bound limits and reduces the queue occupancy that cannot be achieved with store-and-forward mechanisms. Finally, we describe the very promising preliminary results obtained by the simulation of a still open study, and discover a new potential future research field.
