Improving GridFTP performance using the Phoebus session layer

Phoebus is an infrastructure for improving end-to-end throughput in high-bandwidth, long-distance networks by using a "session layer" protocol and "gateways" in the network. Phoebus has the ability to dynamically allocate network resources and to use segmentspecific transport protocols between gateways, as well as to apply other performance-improving techniques on behalf of the user.
