    • Design, deployment and validation of SDN controller for metro/access optical switching nodes 

      Montero Herrera, Rafael (Universitat Politècnica de Catalunya, 2015-09-26)
      Master thesis
      Open Access
      This document presents the design and implementation of OPTNODE. OPTNODE is a new SDN application that runs on top of Opendaylight's abstraction layer. The application has been designed using a set of models (MD-SAL), which ...

    • Enabling multi-segment 5G service provisioning and maintenance through network slicing 

      Montero Herrera, Rafael; Agraz Bujan, Fernando; Pagès Cruz, Albert; Spadaro, Salvatore (2020-01-03)
      Article
      Open Access
      The current deployment of 5G networks in a way to support the highly demanding service types defined for 5G, has brought the need for using new techniques to accommodate legacy networks to such requirements. Network Slicing ...

    • End-to-end 5G service deployment and orchestration in optical networks with QoE guarantees 

      Montero Herrera, Rafael; Agraz Bujan, Fernando; Pagès Cruz, Albert; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      The upcoming 5G deployments will impose stringent requirements. Optical networks control and resource orchestration is set to potentially turn into software-defined approaches in order to address such requirements. As a ...

    • Experimental assessment of VDC provisioning in SDN/OpenStack-based DC infrastructures with optical DCN 

      Pagès Cruz, Albert; Agraz Bujan, Fernando; Montero Herrera, Rafael; landi, Giada; Monno, Roberto; Aznar, Jose; Viñes, Albert; Jackson, Chris; Simeonidou, Dimitra; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference report
      Restricted access - publisher's policy
      VDC provisioning requires the coordinated configuration of several types of resources. We present a DC architecture for the orchestration and provisioning of VDC instances on top of DCs with optical DCN and experimentally ...

    • Orchestrating virtual slices in data centre infrastructures with optical DCN 

      Pagès Cruz, Albert; Agraz Bujan, Fernando; Montero Herrera, Rafael; Landi, Giada; Capitani, Marco; Gallico, Domenico; Biancani, Matteo; Nejabati, Reza; Simeonidou, Dimitra; Spadaro, Salvatore (2019-07-01)
      Article
      Open Access
      The emergence of new paradigms and services is pushing the limits of nowadays cloud infrastructures. It is a fact that current solutions lack in the flexibility and configurability to adapt to heterogeneous requirements ...

    • Real-time maintenance of latency-sensitive 5G services through network slicing 

      Montero Herrera, Rafael; Agraz Bujan, Fernando; Pagès Cruz, Albert; Spadaro, Salvatore (2020-06-30)
      Article
      Open Access
      Network Slicing appears as one of the enabling technologies for 5G networks to accommodate services with different requirements and availability. The present work, seizes the use of network slicing and focuses on the ...

    • Resource optimization in SDN-based inter/intra data centre networks
