In this paper, we consider the max-min fair resource allocation problem as applied to elastic flows. We are interested in computing the optimal max-min fair rate allocation. The proposed approach is a linear programming based one and allows the computation of optimal routing paths with regard to max-min fairness, in stable and known traffic conditions. We(More)
In the past years, telecommunications networks have seen an important evolution with the advances in optical technologies and the explosive growth of the Internet. Several optical systems allow a very large transport capacity, and data tra c has dramatically increased. Telecommunications networks are now moving towards a model of high-speed routers(More)
This document introduces the main MVNO solutions. It attempts to identify what are the strategic elements in the network architecture. The general trend is most probably an evolution towards an MVNO owning the whole core network architecture and buying access service to an MNO. A cost oriented pricing mode for these access services should be put in place,(More)
In this study we provide an economic analysis of the energy consumption savings obtained by introducing research results of the European project CONVINcE for Video On Demand and Video “over the top” (OTT) services. This should allow positioning quantitatively possible savings in the end-to-end chain, including service suppliers (head-ends),(More)
