Collector un nombre inconnu de coupons

Dans les algorithmes de cartographie d'Internet, l'un des problemes cl'e `a r'esoudre est celui de la d'ecouverte des differentes interfaces de sorties d'un routeur en cas dequilibrage de charge: combien de sondes doit-on envoyer tester la connexion pour etre raisonnablement certain d'avoir d'ecouvert toutes les interfaces ? Une des solutions existante est une variante du probleme du collecteur de coupon qui consiste 'a associer 'a chaque nombre d'interfaces d'ecouverts un nombre de sondes au-del'a duquel on consid'ere que l'on peut s'arreter. Dans cet article, nous donnons une formule close pour l'association et prouvons sa quasi-optimalit'e.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

  • Wang H.
  • Wu Q.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
