–This paper considers two important aspects related to the control plane of Traffic Engineered IP/MPLS networks: the " flooding reduction " mechanisms and the evaluation of processing cost for signaling and routing protocols. The flooding reduction mechanisms are needed to reduce the amount of information exchanged by Traffic Engineering enabled routing(More)
After a review of the motivating factors that claim for traffic engineering in next generation infrastructures based on Internet Protocol (IP), this paper briefly reviews the main issues relating to MPLS technology and the possibility to realize a unique control plane in a multi-layer network based on the extended version of MPLS: the GMPLS. In particular,(More)
— This work presents Xhaul: the 5G Integrated Fron-thaul/Backhaul. Xhaul aims at developing an adaptive, sharable, cost-efficient 5G transport network solution integrating the fronthaul and backhaul segments of the network. This transport network will flexibly interconnect distributed 5G radio access and core network functions, hosted on in-network cloud(More)
Today's networking environment exhibits significant traffic variability and squeezing profit margins. An adaptive and economics-aware traffic management approach, needed to cope with such environment , is proposed that acts on short timescales (from minutes to hours) and employs an economics-based figure of merit to rellocate bandwidth in an MPLS context.(More)
New Generation networks will have to cope with a huge growth of IP traffic and with a need of flexibility to promptly react to traffic changes. In order to meet such requirements, a traffic engineering solution for new generation multi-layer networks based on the GMPLS paradigm is proposed. The proposed approach is based on a hybrid solution for the(More)
