    • Decentralized trust in the inter-domain routing infrastructure 

      Paillissé Vilanova, Jordi; Manrique, Jan; Bonet, Guillem; Rodríguez Natal, Alberto; Maino, Fabio; Cabellos Aparicio, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
      Article
      Open Access
      Inter-domain routing security is of critical importance to the Internet since it prevents unwanted traffic redirections. The current system is based on a Public Key Infrastructure (PKI), a centralized repository of digital ...
    • Decoupling state from control in software-defined networking 

      Rodríguez Natal, Alberto (Universitat Politècnica de Catalunya, 2016-07-04)
      Doctoral thesis
      Open Access
      Software-Defined Networking (SDN) arose as a solution to address the limitations of traditional networking. In SDN networks, the control-plane is decoupled from the data-plane devices and logically centralized in a new ...
    • Distributed access control with blockchain 

      Paillissé Vilanova, Jordi; Subirà Nieto, Jordi; López Brescó, Albert; Rodríguez Natal, Alberto; Ermagan, Vina; Maino, Fabio; Cabellos Aparicio, Alberto (2019)
      Conference report
      Restricted access - publisher's policy
      The specification and enforcement of network-wide policies in a single administrative domain is common in today's networks and considered as already resolved. However, this is not the case for multi-administrative domains, ...
    • Global state, local decisions: Decentralized NFV for ISPs via enhanced SDN 

      Rodríguez Natal, Alberto; Ermagan, Vina; Noy, Ariel; Sahai, Ajay; Kaempfer, Gideon; Barkai, Sharon; Maino, Fabio; Cabellos Aparicio, Alberto (2017-04-14)
      Article
      Open Access
      The network functions virtualization paradigm is rapidly gaining interest among Internet service providers. However, the transition to this paradigm on ISP networks comes with a unique set of challenges: legacy equipment ...
    • Iterative research method applied to the design and evaluation of a dynamic multicast routing scheme 

      Papadimitriou, Dimitri; Coras, Florin-Tudorel; Rodríguez Natal, Alberto; Carela Español, Valentín; Careglio, Davide; Fàbrega, Lluís; Vila, Pere; Demeester, Piet M.A. (Springer-Verlag Berlin Heidelberg, 2013)

      Mestres Sugrañes, Albert; Rodríguez Natal, Alberto; Carner Marsal, Josep; Barlet Ros, Pere; Alarcón Cot, Eduardo José; Sole, Marc; Muntés Mulero, Victor; Meyer, David; Barkai, Sharon; Hibbett, Mike J.; Estrada, Giovani; Coras, Florin-Tudorel; Ermagan, Vina; Latapie, Hugo; Cassar, Chris; Evans, John; Walrand, Jean; Cabellos Aparicio, Alberto (2017-07-01)
      Article
      Open Access
      The research community has considered in the past the application of Artificial Intelligence (AI) techniques to control and operate networks. A notable example is the Knowledge Plane proposed by D.Clark et al. However, ...

    • LISP: a southbound SDN protocol? 

      Rodríguez Natal, Alberto; Portoles Comeras, Marc; Ermagan, Vina; Lewis, Darrel; Farinacci, Dino; Maino, Fabio; Cabellos Aparicio, Alberto (2015-07-01)
      Article
      Open Access
      The Locator/ID Separation Protocol (LISP) splits current IP addresses overlapping semantics of identity and location into two separate namespaces. Since its inception the protocol has gained considerable attention from ...
