    This paper presents the main concepts of the IST Project FAIN “Future Active IP Networks” [10], a three-year collaborative research project, whose main task is to develop and validate an open, flexible, programmable and ...
  • X-Type Interface for Management of Multidomain Multitechnology Networks 

    Serrat Fernández, Juan (Morris Sloman, 1999)
    Text en actes de congrés
    Accés obert
    The specification and implementation of Xcoop interfaces has received great attention in the last few years. In fact, the appropriate design of this system component is a key aspect for efficient and seamless co-operative ...
  • DSP based platform for an enhanced HF channel simulator 

    Serrat Fernández, Juan (IEE Pubs, 1997)
    Text en actes de congrés
    Accés obert
    With the aim of improving existing tools for testing new HF transmission systems, this article describes a modification of the basic Watterson (1970) model which can be implemented without any extra added complexity with ...
  • Performance analysis of a hybrid ARQ system in half duplex transmission at 2400 BPS 

    Dalmau Royo, Jordi; Serrat Fernández, Juan (IEEE IEEE, 1991)
    Text en actes de congrés
    Accés obert
    Hybrid ARQ/FEC protocols have been proposed to provide high data link integrities whilst keeping at the same time a high mean throughput rate. Nevertheless, hybrid ARQ strategies offer a lot of choices and none of them can ...
  • Semantic validation of affinity constrained service function chain requests 

    Bouten, Niels; Claeys, Maxim; Mijumbi, Rashid; Famaey, Jeroen; Latré, Steven; Serrat Fernández, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Network Function Virtualization (NFV) has been proposed as a paradigm to increase the cost-efficiency, flexibility and innovation in network service provisioning. By leveraging IT virtualization techniques in combination ...
  • A dynamic pricing algorithm for a network of virtual resources 

    Naudts, Bram; Flores Méndez, Mario Rogelio; Mijumbi, Rashid; Verbrugge, Sofie; Serrat Fernández, Juan; Colle, Didier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A service chain is a combination of network services (e.g. network address translation (NAT), a firewall, etc.) that are interconnected to support an application (e.g. video-on-demand). Building a service chain requires a ...
  • gSLM: the initial steps for the specification of a service management standard for federated e-Infrastructures 

    Serrat Fernández, Juan; Szepieniec, Tomasz; Belloum, Adam S.Z.; Rubio-Loyola, Javier; Appleton, Owen; Schaaf, Thomas; Kocot, Joanna (2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a methodology used to create a site independent assessment process of the capabilities of service management systems in federated e-infrastructures that can contribute to introduce or improve service ...
  • A system approach on power distribution supervisory control catalog 

    Delgado Penin, José A.; Serrat Fernández, Juan (Institute of Electrical and Electronics Engineers (IEEE), 1982)
    Text en actes de congrés
    Accés obert
    The electrical energy distribution networks need remote control systems that are centralised and integrated as far as the functions they can develop are concerned. The need for a thinking unit at the line head for managing ...
  • Chirp Fourier Processor Design: A Time-domain Approach 

    Delgado Penin, José A.; Serrat Fernández, Juan (Institute of Electrical and Electronics Engineers (IEEE), 1990)
    Text en actes de congrés

  • Power distribution supervisory control system by polling 

    Delgado Penin, José A.; Serrat Fernández, Juan (Institute of Electrical and Electronics Engineers (IEEE), 1983)
    Text en actes de congrés
    Accés obert
    This paper describes a new Supervisory Control System (SCS) which adopts a dynamic polling structure. The need for a thinking unit at the line head for manaing a SCS is unavoidable. The thinking unit (mP) moreover, allows ...
