Resource management for multimedia applications, distributed in open and heterogeneous home networks

Maxime Louvel, Alain Plantec, Jean-Philippe Babau
2013 Journal of systems architecture  
The home network is an open, heterogeneous and distributed environment where ensuring multimedia applications' quality of service is a main concern.  ...  Mechanisms to reserve resources (CPU, memory, network) and architectures using them already exist.  ...  CPU There is two types of scheduling algorithms allowing for CPU reservation [17, 18] . The algorithms of the first type are based on a server and use a real time scheduler.  ...

Scheduler support for video-oriented multimedia on client-side virtualization

Hwanju Kim, Jinkyu Jeong, Jaeho Hwang, Joonwon Lee, Seungryoul Maeng
2012 Proceedings of the 3rd Multimedia Systems Conference on - MMSys '12  
An implementation of our scheme has shown that the virtual machine hosting a video-oriented application receives propoer CPU scheduling even when other virtual machines host CPU intensive workloads.  ...  This paper presents a new scheduling scheme for the hypervisor to transparently identify if the workload handles multimedia and to provide proper scheduling supports.  ...  In a virtualized system, a VM scheduler provides each VM with a certain proportion of physical CPU, with which each guest OS schedules its tasks locally.  ...

Real-time scheduling for multimedia services

Thomas D. Little, John F. Gibbon, Kadiresan Annamalai
1993 High-Speed Fiber Networks and Channels II  
A real-time scheduling system designed for multimedia data types is also required to orchestrate communications channels, disk storage units, output devices, and the CPU.  ...  Within this framework we propose the application of a statistical resource reservation mechanism and a real-time session scheduler.  ...  However, a real-time operating system is not a substitute for a real-time multimedia scheduler.  ...
