TeraPaths is a DOE MICS/SciDAC-fundedproject conceived to address the needs of the high energy and nuclear physics scientific community for effectively protecting data flows of various levels of priority through modern high-speed networks. TeraPaths is rapidly evolving from a last-mile, LAN QoS provider to a distributed end-to-end network path QoS negotiator through multiple administrative domains. Developed as a web service-based software system, TeraPaths automates the establishment of network paths with QoS guarantees between end sites by configuring their corresponding LANs and requesting MPLS paths through WANs on behalf of end users. The primary mechanism for the creation of such paths is the negotiation and placement of advance reservations across all involved domains. This paper describes the status of the project, our experiences so far, as well as the directions of our continued work.
