Ultra-low delay for all: live experience, live analysis
TL;DR: This demo dramatically illustrates how replacing 'Classic' TCP congestion control with a 'Scalable' alternative like Data Centre TCP keeps queuing delay ultra-low; not just for a select few light applications like voice or gaming, but even when a variety of interactive applications all heavily load the same (emulated) Internet access.

Flexible Device Sharing in PCIe Clusters using Device Lending
Jonas Markussen,Lars Bjørlykke Kristiansen,Håkon Kvale Stensland,Friedrich Seifert,Carsten Griwodz,Pål Halvorsen +5 more
TL;DR: Using the extended Device Lending, it becomes possible to dynamically "pass through" physical remote devices to VM guests while still retaining the flexibility of virtualization, something that previously required extensive facilitation in both hypervisor and device drivers in the form of paravirtualization.
Proceedings ArticleDOI
Replication for a distributed multimedia system
TL;DR: The main contribution of this paper is the identification of new replication requirements in distributed media systems and a multicast-based update propagation mechanism by which not only the update events are signaled, but also the updated data are exchanged between replication managers.

TL;DR: In this article, a system for real-time panorama video generation from an array of low-cost CCD HD video cameras is presented. But processing the different steps of a panorama-video pipeline in realtime is challenging due to the high data rates and the stringent requirements of timeliness.
Proceedings ArticleDOI

TL;DR: Using a virtual reality (VR) environment, this work has designed and developed a game-like system aiming to mimic an abused child that can help to assist police and child protection service (CPS) personnel in interview training of maltreated children.
