    1919 * '''XSP Path Signaling''' – The XSP Path implementation provides a general interface for configuring dynamic network resources, including technologies such as OpenFlow and OSCARS (e.g. used by Internet2 ION), and a framework for driving emerging Software Defined Networks (SDNs).  A common set of  network “rules” may be specified via the XSP API and signaled to XSP-enabled controllers within the network, known in our experiments as a daemon called XSPd-SDN.  Each rule is interpreted by an appropriate “rule handler” loaded by XSPd-SDN and applied within the network.  The requested application is notified when the path is ready.

    2323 * '''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.
