    • A Fully Scalable and Distributed Architecture for Video-on-Demand 

      Cores Prado, Fernando; Ripoll, A.; Luque, Emilio (Springer Verlag, 2001)
      In spite of the attractiveness of Video-on-demand (VoD) services, their implantation to the present has not been as widespread as could have been desired due to centralized VoD systems have a limited streaming capacity ...
    • Accurate consistency-based MSA reducing the memory footprint 

      Lladós Segura, Jordi; Cores Prado, Fernando; Guirado Fernández, Fernando; Lérida Monsó, Josep Lluís (Elsevier, 2021)
      Background and Objective: The emergence of Next-Generation sequencing has created a push for faster and more accurate multiple sequence alignment tools. The growing number of sequences and their longer sizes, which require ...
    • Cooperative scheduling mechanism for large-scale peer-to-peer computing systems 

      Rius Torrentó, Josep Maria; Cores Prado, Fernando; Solsona Tehàs, Francesc (Elsevier, 2013)
      Over recent years, peer-to-peer (P2P) systems have become an important part of Internet. Millions of users have been attracted to their structures and services. P2P computing is a distributed computing paradigm that uses ...
    • Designing an effective P2P system for a VoD system to exploit the multicast communication 

      Yang, X. Y.; Cores Prado, Fernando; Hernández Budé, Porfidio; Ripoll, A.; Luque, Emilio (Elsevier, 2010)
      A distributed video-on-demand system (DVoD) with multiple server-nodes is a cost-effective and faulttolerant solution for a high scalable enterprise video-on-demand (VoD) system. However, such a serveroriented design is ...
    • Double P-Tree: A Distributed Architecture for Large-Scale Video-on-Demand 

      Cores Prado, Fernando; Ripoll, A.; Luque, Emilio (Springer Verlag, 2002)
      In order to ensure a more widespread implementation of video-ondemand (VoD) services, it is essential that the design of cost-effective largescale VoD (LVoD) architectures be able to support hundreds of thousands ...
    • Dynamic Distributed Collaborative Merging Policy to Optimize the Multicasting Delivery Scheme 

      Yang, X. Y.; Hernández Budé, Porfidio; Cores Prado, Fernando; Ripoll, A.; Suppi, Remo; Luque, Emilio (Springer Verlag, 2005)
      The advance of Internet 2 and the proliferation of switches and routers with level three functionalities made the multicast one of the most feasible video streaming delivering techniques for the near future. Assuming ...
    • DynaPeer: A Dynamic Peer-to-Peer Based Delivery Scheme for VoD Systems 

      Souza, Leandro; Cores Prado, Fernando; Yang, Xiaoyuan; Ripoll, A. (Springer Verlag, 2007)
      Supporting Video-on-Demand (VoD) services in Internet is still a challenging issue due to high bandwidth requirement of multimedia contents and additional constraints imposed by such environment: higher delays and jitter, ...
    • Exploiting parallelism on progressive alignment methods 

      Orobitg Cortada, Miquel; Guirado Fernández, Fernando; Notredame, Cedric; Cores Prado, Fernando (Springer Verlag, 2011)
      Multiple Sequence Alignment (MSA) constitutes an extremely powerful tool for important biological applications such as phylogenetic analysis, identification of conserved motifs and domains and structure prediction. In ...
    • Exploiting Traffic Balancing and Multicast Efficiency in Distributed Video-on-Demand Architectures 

      Cores Prado, Fernando; Ripoll, A.; Qazzaz, Bahjat; Suppi, Remo; Yang, Xiaoyuan; Hernandez, Porfidio; Luque, Emilio (Springer Verlag, 2003)
      Distributed Video-on-Demand (DVoD) systems are proposed as a solution to the limited streaming capacity and null scalability of centralized systems. In a previous work, we proposed a fully distributed large-scale ...
    • Fully distributed authentication with locality exploitation for the CoDiP2P peer-to-peer computing platform 

      Cores Prado, Fernando; Guirado Fernández, Fernando; Naranjo, J. A. M.; Casado, L. G. (Springer Verlag, 2013)
      CodiP2P is a distributed platform for computation based on the peer-topeer paradigm. This article presents a novel distributed authentication method that suits the platform and adapts to its characteristics. The developed ...
    • Incentive mechanism for scheduling jobs in a peer-to-peer computing system 

      Rius Torrentó, Josep Maria; Estrada, Soraya; Cores Prado, Fernando; Solsona Tehàs, Francesc (Elsevier, 2012)
      Peer-to-Peer (P2P) computing, the harnessing of idle CPU cycles through the Internet, offers new research challenges in distributed computing. One of the most critical aspects in the design of P2P systems is the development ...
    • Providing VCR in a Distributed Client Collaborative Multicast Video Delivery Scheme 

      Yang, X. Y.; Hernández, P.; Cores Prado, Fernando; Ripoll, A.; Suppi, Remo; Luque, Emilio (Springer Verlag, 2006)
      In order to design a high scalable video delivery technology for VoD systems, two representative solutions have been developed: multicast and P2P. Each of them has limitations when it has to implement VCR interactions ...
