  • 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 ...
  • 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

    Following the iterative research cycle process, this chapter elaborates a methodology and documents the steps followed for the design of a dynamic multicast routing algorithm, referred to as Greedy Compact Multicast Routing. ...
  • Knowledge-defined networking 

    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 ...
  • LISP-MN: mobile networking through LISP 

    Rodríguez Natal, Alberto; Lorand, Jakab; Portoles Comeras, Marc; Ermagan, Vina; Natarajan, Preethi; Maino, Fabio; Meyer, David; Cabellos Aparicio, Alberto (2013-05)
    Article

  • Programmable overlays via OpenOverlayRouter 

    Rodríguez Natal, Alberto; Paillise, Jordi; Coras, Florin-Tudorel; López Brescó, Albert; Lorand, Jakab; Portoles Comeras, Marc; Natarajan, Preethi; Meyer, David; Farinacci, Dino; Maino, Fabio; Cabellos Aparicio, Alberto; Ermagan, Vina (2017-06-01)
    Article
    Open Access
    Among the different options to instantiate overlays, the Locator/ID Separation Protocol (LISP) [7] has gained significant traction among industry and academia [5], [6], [8]–[11], [14], [15]. Interestingly, LISP offers a ...
