ESnet Quality of Service

Traffic jams on the Internet pose a significant problem for scientific collaborators. Real-time remote control of experimental facilities or computational simulations requires reliable quality of service (QoS) -- in other words, guaranteed bandwidth, regardless of Internet traffic. While major router vendors are starting to improve QoS, it is still inadequate for collaborative research. The goals of this project are to supply useful, deployable, flexible QoS to the DOE research community as an ESnet service and demonstrate to industry how administratively heterogeneous QoS might be implemented and deployed.

The objectives of the ESnet QoS project are

Support resource discovery and aggregation (brokering)
Ensure that a network domain can control use of its resources (authorization)
Track capacity and commitment of every network element involved to accurately perform admission control
Allow for network configuration changes, and cancel or modify reservations accordingly
Perform reservation bookkeeping without touching network elements
Resist misappropriation.

This project is being done at Lawrence Berkeley National Laboratory.
