Metro networks, being at the meeting point between telecom operators and over-the-top service providers, are particularly well-suited to the introduction of some level of dynamics in the optical networks, leveraging elastic building blocks such as transponders and optical nodes. We review some metro networks challenges appealing for innovative solutions in the short-medium term. Today elastic optical networks are first overviewed with the most deployed application examples. We then highlight a few features of next generation of optical networks and outline the main road towards this next generation with network experiments and associated use cases.

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 ...

  • 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 ...
