      The peer-to-peer (P2P) overlay networks are distribution topologies that take advantage of the ability that their nodes have to forward the information that they receive. For the particular case of video transmission using ...
    • Topology analysis of auto load-balancing RWA in optical burst-switched networks 

      Triay Marquès, Joan; Cervelló Pastor, Cristina (2011)
      Conference lecture
