    2828 * '''Adapting to Network Conditions''' – Phoebus Gateways (PGs) are XSP-based performance-enhancing network services.  Our experiments have evaluated the ability of PGs to accelerate transfers over ION and ProtoGENI backbone resources.  Phoebus implements protocol translation and adaptation that can significantly improve performance over LFNs and challenged network paths.  Our testing shows a 50-60% improvement when utilizing the Phoebus-XSP approach for common network transfer tools and benchmarks such as GridFTP and iperf (shown in the performance chart below).  Future experiments will allow PGs to select optimal paths based on prevailing network conditions.
