Enabling low-latency applications using programmable networks

Throughout the last decades, communication networks have become embedded into almost every aspect of our day-to-day lives (e.g., watching movies, online shopping, sharing moments with friends and family). Moreover, as the support for the transport of audio and video became the norm, new application domains have kept emerging every day. One of...

S-Query: Opening the Black Box of Internal Stream Processor State

At the moment we are witnessing the maturation of distributed streaming dataflow systems whose use-cases have departed from the mere analysis of streaming windows and complex-event processing, as they now extend to cloud applications, workflows and even e-commerce. The state of streaming operators has been so far hidden from external...

High throughput data interfacing: for real-time medical imaging applications

Current high-end medical X-ray intervention devices provide a tremendous amount of high-definition images per second. Combined with the additional inputs from the numerous auxiliary devices, processing and compositing the data in real-time quickly becomes an arduous engineering challenge. Furthermore, the critical nature of this application...

A pipeline for multiparty volumetric video conferencing: Transmission of point clouds over low latency DASH

The advent of affordable 3D capture and display hardware is making volumetric videoconferencing feasible. This technology increases the immersion of the participants, breaking the flat restriction of 2D screens, by allowing them to collaborate and interact in shared virtual reality spaces. In this paper we introduce the design and development...

With the current advancements in technologies, applications are becoming more advanced and research is being performed into adding more modalities to these applications to enrich the experience and increase their capabilities and uses.<br/> he performance of these applications...

Exploring Gravitational Waves Recordings with Machine Learning Techniques

The study of Gravitational Waves (GWs) opened a new window of possibilities to improve our understanding of the Universe. GWs provide suitable astronomical messengers for studying events that were not possible before through electromagnetic radiation, or in other cases complementing their observations. Ground-based interferometers like LIGO have...

FLeet: When time-bounded communication meets high energy-efficiency

With the advent of low-cost, embedded sensor-actuator devices, the applications of cyber-physical systems have spread multi-fold in domains like infrastructure, manufacturing, automation, etc. Wireless sensor-actuator networks (WSANs) act as the backbone for applications in these domains. Typical WSAN deployments focus on energy-efficiency ...

Fast network congestion detection and avoidance using P4

Along with exciting visions for 5G communications and the Tactile Internet, the networking requirement of attaining extremely low end-to-end latency has appeared. While network devices are typically equipped with buffers to counteract packet loss caused by short-lived traffic bursts, the more those buffers get filled, the more delay is added to...

Feeding High-Bandwidth Streaming-Based FPGA Accelerators

A new class of accelerator interfaces has signi cant implications on system architecture. An order of magnitude more bandwidth forces us to reconsider FPGA design. OpenCAPI is a new interconnect standard that enables attaching FPGAs coherently to a high-bandwidth, low- latency interface. Keeping up with this bandwidth poses new challenges for...

Anonymous HD video streaming

No scalable privacy-enhancing technologies exists that is capable of anonymous HD video streaming. Our paper discusses the new anonymizer built into Tribler, a social content-sharing client. With anonymous HD-video streaming as the main objective requirements as at least 10 Mbit/s throughput, user bandwidth donations and NAT-traversal are...
