Real-time analytics provides the promise to enable the rapid detection and mitigation of security, reliability, and performance issues in the emerging area of virtualized services and networks. These multi-domain Software Defineded Networks (SDN), emerging in the industry, can be dynamically reconfigured in real-time through software, allowing rapid response to changes in service demands, and can be used in conjunction with cloud-based services. However, these networks also introduce new vulnerabilities and threats to security and reliability, as well as new types of performance issues. As the volume, variety, velocity, and veracity of data in these networks is vast, real-time analytics needs to be customized to provide autonomic actions once a potential problem is detected in the network. In this paper, we describe a real-time analytics architecture {with dynamic and varying granularity in time, data, probability, and specifcity for virtualized networks that supports the detection and mitigation of security, reliability and performance issues in real-time.

  • 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 ...
