–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)
Next-generation network infrastructure should support different services and several levels of quality of service (QoS) and resilience. The main requirements for such multiservice networks are flexibility, effective utilization of network resources, and ability to react to traffic demand changes with time. These requisites lead to the fact that(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)
This paper describes a novel multilayer (ML) path computation element (PCE) architecture based on a hybrid approach. Such a method operates in all network life cycles, optimizing both the design and the operative phases. The hybrid PCE is based on combined non-realtime and real-time operation and is able to integrate control and management functions. This(More)
