Dynamic IP Tunneling for Next Generation Mobile Networks

The paper describes the principles of a novel mechanism that is aiming at providing unprecedented Quality of Experience (QoE) in next generation mobile networks. The main benefits include: (i) enabling dynamic IP tunnel management (establishing and tearing down) with terminating point in the mobile device instead of the traditional base station; (ii) enabling multiple parallel tunnels (e.g., Generic Routing Encapsulation (GRE)) between an anchor node and a mobile device, where a specific tunnel may support differentiated Quality of Service (QoS) requirements for a targeted service class; (iii) enabling advanced network protocol support for service flows split across multiple Radio Access Technologies (M-RATs), whenever it may be deemed necessary to support and maintain a targeted QoS level per service flow; (iv) allowing to aggregate the necessary bandwidth to meet the QoS requirements per service flow if no single RAT can fulfill them alone; (v) supporting massive M-RAT capacity aggregation for enhanced scalability and very large throughput.

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 ...
