    Conference report
    Open Access
    In the quest of large-scale quantum computers, multi-core distributed architectures are considered a compelling alternative to be explored. A crucial aspect in such approach is the stringent demand on communication among ...
  • One protocol to rule them all: Wireless network-on-chip using deep reinforcement learning 

    Jog, Suraj; Liu, Zikun; Franques, Antonio; Fernando, Vimuth; Abadal Cavallé, Sergi; Torrellas, Josep; Hassanieh, Haitham (USENIX Association, 2021)
    Conference report
    Open Access
    Wireless Network-on-Chip (NoC) has emerged as a promising solution to scale chip multi-core processors to hundreds and thousands of cores. The broadcast nature of a wireless network allows it to significantly reduce the ...
  • WiDir: A Wireless-Enabled Directory cache coherence protocol 

    Franques, Antonio; Kokolis, Apostolos; Abadal Cavallé, Sergi; Fernando, Vimuth; Misailovic, Sasa; Torrellas, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    As the core count in shared-memory manycores keeps increasing, it is becoming increasingly harder to design cache-coherence protocols that deliver high performance without an inordinate increase in complexity and cost. In ...
  • Preventing route leaks using a decentralized approach: an experimental evaluation 

    Ferriol Galmés, Miquel; Coll Aumatell, Roger; Cabellos Aparicio, Alberto; Ren, Shoushou; Wei, Xinpeng; Liu, Bingyang (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    In the inter-domain routing infrastructure, a route leak is defined as a violation of the routing policy agreed between two Autonomous Systems (AS). Route leaks have resulted in large-scale outages on the Internet, taking ...
  • Internet routing paths stability model and relation to forwarding paths 

    Papadimitriou, Dimitri; Careglio, Davide; Tarissan, Fabien; Demeester, Piet M.A. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Open Access
    Analysis of real datasets to characterize the local stability properties of the Internet routing paths suggests that extending the route selection criteria to account for such property would not increase the routing path ...
  • Nonparametric statistical methods to analyze the internet connectivity reliability 

    Papadimitriou, Dimitri; Careglio, Davide (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    Facing computational complexity when modeling network reliability by means of parametric models and corresponding statistical methods, in the present study, we apply nonparametric statistical methods, such as the Kaplan-Meier ...
  • On the experimentation of the novel GCMR multicast routing in a large-scale testbed 

    Careglio, Davide; Papadimitriou, Dimitri; Agraz Bujan, Fernando; Sahhaf, Sahel; Perelló Muntan, Jordi; Tavernier, Wouter (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference lecture
    Open Access
    Originally defined in the 90s, multicast is nowadays (re)gaining interest given the increasing popularity of multimedia streaming/content traffic and the explosion of cloud services. In fact, multicast yields bandwidth ...
  • ILP modeling of many-to-many transmissions in computer networks 

    Walkowiak, Krzysztof; Bulira, Damian; Careglio, Davide (Polish Academy of Sciences, 2012)
    Conference report
    Open Access
    Information flow in nowadays networks spreads in the exponential way. This fact is caused by the intensive changes in the Internet communication paradigms. Transmission in the Internet evolved from the simple one-to-one ...
  • Guaranteeing QoS requirements in long-haul RINA networks 

    León Gaixas, Sergio; Perelló Muntan, Jordi; Careglio, Davide; Tarzan Lorente, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    In the last years, networking scenarios have been evolving, hand-in-hand with new and varied applications with heterogeneous Quality of Service (QoS) requirements. These requirements must be efficiently and effectively ...
  • A hybrid packet/circuit optical transport architecture for DCN 

    Panahi, Nogol; Careglio, Davide; Solé Pareta, Josep (2019)
    Conference report
    Open Access
    The aim of this paper is to move away from today's multi-tier, manually operated, and performance limited Data Centre Network (DCN) towards more scalable, flexible, and optimized architecture of tomorrow. We propose a new ...
  • Joint latency and reliability-aware controller placement 

    Rasol, Kurdman Abdulrahman Rasol; Domingo Pascual, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    In network architectures based on Software Defined Networking (SDN) the control plane (control logic) is separated from the network data plane (forwarding plane) while traditional network routers combine both. Software ...
  • Dataflow-architecture co-design for 2.5D DNN accelerators using wireless network-on-package 

    Guirado Liñan, Robert; Kwon, Hyoukjun; Abadal Cavallé, Sergi; Alarcón Cot, Eduardo José; Krishna, Tushar (Association for Computing Machinery (ACM), 2021)
    Conference report
    Open Access
    Deep neural network (DNN) models continue to grow in size and complexity, demanding higher computational power to enable real-time inference. To efficiently deliver such computational demands, hardware accelerators are ...
