vNS: a modular programmable virtual network switch

  • Gallo M.
  • Pianese F.

Virtual software switches are evolving: from simple communication facilities connecting virtual machines to the outside network, they are growing into complex subsystems supporting an increasing number of functionalities at multiple network layers. In line with recent trends introducing stateless and stateful processing in virtual switches, we present in this poster vNS, a modular programmable virtual network switch that enables transport stack offloading from the VM to the host, together with a number of transport and application layer functions. We detail the architecture of vNS and provide a preliminary evaluation.

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 ...
