Projects Using HFSC

At Carnegie Mellon University, the Darwin project for customizable resource management for value-added network services utilizes HFSC's per flow real-time guarantees and hierarchical link-sharing capabilities to provide guaranteed QoS, customizable resource sharing, and virtual networking between application end-points and network servers.

CAIRN is a DARPA sponsored high-speed network testbed connecting multiple universities and research institutions. HSFC is now part of the CAIRN-2.5 source distribution. As a collaboration between CMU and ISI East, the VNS project is creating a set of tools to provide a virtual network service on CAIRN. Using HFSC as the basis, this service will enable researchers using CAIRN as their platform to have easy and full control over the communication quality between experiment end-points and routers.

At ETH Zurich and Washington University, researchers of the Router Plugins project designed and implemented a high performance, modular, extended integrated services router software architecture in the NetBSD kernel. Code modules, called plugins, can be dynamically added and configured at run time. HFSC is being used in this architecture as a packet scheduling plugin.

As a collaboration between Carnegie Mellon University, Rice University, University of Virginia, and MCI Telecommunications, supported by the Special Projects in Networking Program of the National Science Foundation, the INDRA project is developing the theoretical underpinnings of an integrated set of network control algorithms for the Next Generation Internet and building a complete prototype implementation of the proposed algorithms on the vBNS network. The H-FSC QoS Kernel is used as part of the infrastructure.
