Several RTOSs with QoS focus: much research is done on networking support for continuous-media applications, very few projects tackle related OS issues, such as scheduling and file system support for bounded response time: overview, status, download, installation, use, documentation, papers.

Frequently asked questions about IP quality of service. pdf version is available.

Has information loss become so crucial? Is there real demand for highly available networks? Or are network OEMs, fighting a bad economy, making high-tech versions of detergent ads claiming new and improved. [Vaughan-Nichols & Associates]

Set of links to, descriptions of, information on various QoS technologies.

Short, annotated, alphabetically sorted list and links, part of larger system.

High-Performance distributed object environment emphasizing adaptive end-to-end QoS guarantees. Abstract, components, documents, people, funding.

One-user, general purpose OS built on a protected memory, POSIX threads RT kernel; full kernel, device drivers, file systems, and network protocols runs in about 200 K RAM; now runs on x86 CPUs but designed for easy portability. [Open source, GPL]

Free for non-commercial use. Communication-oriented OS focused on network systems: network-attached devices, set-top boxes, and hand-held devices. Fast, customizable, based on new ways to structure and construct OSs: The Path: how data flows between end-points in a system; paths are primary objects to which resources are assigned. Also exploring new compiler technologies for system design and implementation, based on this insight: extensible OSs are worthless if no one can build or extend them.

SUpport for Multimedia in Operating systems, Lancaster University: microkernel OS with facilities to support distributed realtime and multimedia applications and ODP-based multimedia distributed application platforms.

Extensible technology for adaptive systems: researching tools, techniques to incrementally specialize OSs to optimize performance, meta-programming languages to let applications declare specialization needs to OSs, and to specialize distributed systems to enhance survivability via code diversity and specialized response to intrusion.

Object-oriented operating system for large-scale shared-memory multiprocessors. Minimizes data sharing via careful design: often eliminates data sharing even when sharing appears natural. Successor to Hurricane.

Extensible OS, high reusability and modularity, application-directed kernel policy, universal resource interface, take no usual solutions for granted (question everything): software and postscript downloads.
