This paper explores the merger of power utility circuits with that of the information and communication technology (ICT) equipment under the smart grid and the safety implications that this poses, and determines what is the maximum voltage that ICT equipment, designed in accordance with IEC 62368-1 can directly access power-grid ...

la racine du parallélisme

  • Bonald T.
  • Comte C.
  • Mathieu F.

Nous considérons un clusters de serveurs traitant les requêtes en parallèle. Si les clients ont en général intérêt à ce que leurs requêtes soient traitées par le plus grand nombre de serveurs, l'impact du parallélisme sur les serveurs est moins clair : trop faible, il ne permet pas d'utiliser pleinement ...

La Grille de Kleinberg, l'Univers et le Reste

Longtemps source d'anecdotes, le routage dans les petits mondes a été étudié en 2000 par Kleinberg grâce à un modèle simple qui capture l'influence de la construction de liens distants, les raccourcis, sur la navigabilité dans un graphe : la grille de Kleinberg. Tandis que le modèle initial a été ...

  • Raz D.
  • Segall I.

Network Function Virtualization (NFV) is a new networking paradigm in which network functionality is implemented on top of virtual infrastructure deployed over COTS servers. One of the main motivations for the shift of telco operators into this paradigm is cost reduction, thus the efficient use of resources is an important ...

We consider the canonical shared link caching network formed by a source node, hosting a library of $m$ information messages (files), connected via a noiseless multicast link to $n$ user nodes, each equipped with a cache of size $M$ files. Users request files independently at random according to an a-priori ...

5G Radio Access Protocols with Multi-User Detection for URLLC
