The Future of Broadband Access

  • Vetter P.

For the past two decades, Broadband Access has mainly been provided by traditional telecommunication operators and cable TV operators. They have leveraged their existing wireline networks, based on either twisted pair or hybrid fiber coax, to offer triple play services of voice, data and video and have typically operated with a national market focus, serving the needs of their original domestic markets. With the dominance of mobile communications and networking in the last decade, many operators purchased mobile networks in other markets. Then, with the move towards quadruple-play services including wireless services with the triple play offers convergence of fixed and mobile operators in each domestic market began to occur. However, given the hyper-competitive nature of the marketplace, this convergence often came at the expense of further global expansion, creating a relatively localized set of converged operators.

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 ...
