  • A GMPLS/OBS network architecture enabling QoS-aware end-to-end burst transport 

    Pedroso, Pedro; Perelló Muntan, Jordi; Spadaro, Salvatore; Careglio, Davide; Solé Pareta, Josep; Klinkowski, Miroslaw (2010-07-01)
    External research report
    Open Access
    This paper introduces a Generalized Multi-Protocol Label Switching (GMPLS)-enabled Optical Burst Switched (OBS) network architecture featuring end-to-end QoS-aware burst transport services. This is achieved by setting up ...
  • A performance survey on deflection routing techniques for OBS networks 

    Pedrola Escribà, Òscar; Rumley, Sébastien; Careglio, Davide; Klinkowski, Miroslaw; Pedroso, Pedro; Solé Pareta, Josep; Gaumier, Christian (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
    Conference report
    Open Access
    In this paper, we present a survey comparing different deflection routing based techniques applied to optical burst switching (OBS) networks. For such study we consider the E-OBS architecture proposed in [1] which is an ...
  • Adaptive burst admission and forwarding in OBS networks 

    Rumley, Sébastien; Pedrola Escribà, Òscar; Klinkowski, Miroslaw; Pedroso, Pedro; Gaumier, Christian; Careglio, Davide; Solé Pareta, Josep (IEEE, 2009-07-31)
    Conference report
    Open Access
    This paper addresses the problem of controlling the performance of optical burst switching (OBS) networks in presence of non-stationary traffic demands. We propose a joint burst admission control and forwarding mechanism ...
  • An interoperable GMPLS/OBS Control Plane: RSVP and OSPF extensions proposal 

    Pedroso, Pedro; Careglio, Davide; Casellas, Ramon; Klinkowski, Miroslaw; Solé Pareta, Josep (E. Leitgeb, W. Kogler, Z. Ghassemlooy, 2008-07-31)
    Conference report
    Open Access
    The GMPLS/OBS Control Plane is a bold research topic. Optical Burst Switching (OBS) networks need to be capable to be rapidly reconfigured with the aim of achieving an efficient use of bandwidth, low latency and high ...
  • AnyTraffic labeled routing 

    Papadimitriou, Dimitri; Pedroso, Pedro; Careglio, Davide (IEEE Computer Society Publications, 2010-05-23)
    Conference report
    Open Access
    This paper investigates routing algorithms that compute paths along which combined unicast and multicast traffic can be forwarded altogether, i.e., over the same path. For this purpose, the concept of AnyTraffic group is ...
  • AnyTraffic labeled routing for static and dynamic traffic 

    Papadimitriou, Dimitri; Pedroso, Pedro; Careglio, Davide (2009-09-25)
    External research report
    Open Access
    This paper investigates routing algorithms that compute paths along which combined unicast and multicast traffic can be forwarded altogether, i.e., over the same path. For this purpose, the concept of AnyTraffic group is ...
  • AnyTraffic routing algorithm for label-based forwarding 

    Pedroso, Pedro; Pedrola Escribà, Òscar; Papadimitriou, Dimitri; Klinkowski, Miroslaw; Careglio, Davide (IEEE Press and Wiley, 2009-11-30)
    Conference report
    Open Access
    The high capacity provided by packet-switched networks is supporting the proliferation of bandwidth intensive multimedia applications which require multicasting capability. As a consequence on today’s networks, unicast ...
  • AnyTraffic routing algorithm for label-based forwarding 

    Pedroso, Pedro; Pedrola Escribà, Òscar; Papadimitriou, Dimitri; Careglio, Davide; Klinkowski, Miroslaw (2009-06-11)
    External research report
    Open Access
    The high capacity provided by packet-switched networks is supporting the proliferation of bandwidth intensive multimedia applications which require multicasting capability. As a consequence a mixed traffic scenario where ...
  • Dynamic compact multicast routing on power-law graphs 

    Pedroso, Pedro; Papadimitriou, Dimitri; Careglio, Davide (IEEE, 2011)
    Conference report
    Restricted access - publisher's policy
    Compact routing schemes address the fundamental tradeoff between the memory space required to store the routing table entries and the length of the routing paths that these schemes produce. This paper introduces the first ...
  • Virtual topology design in OBS networks 

    Klinkowski, Miroslaw; Pedroso, Pedro; Pioro, Michal; Careglio, Davide; Solé Pareta, Josep (2010)
    Conference report
    Open Access
    The problem of burst losses in OBS networks has an impact on the service quality perceived by end users. In order to guarantee certain level of Service Quality (QoS) in terms of burst losses, wavelength resources have to ...
