| Internet2, G?ANT2, and ESnet Demonstrate Phoebus at SC07 Internet2, ESnet, and G?ANT2 have announced at SC07, the annual international conference on high performance computing, networking, storage, and analysis, the major demonstration of the Phoebus performance framework which allows applications to seamlessly set up dynamic lightpaths regardless of the user's edge network access method. In doing so, Phoebus provides a bridge to enable a broader segment of users to take advantage of the performance and reliability of optical circuit networks such as the Internet2 Dynamic Circuit (DC) Network, ESnet Science Data Network (SDN) and the G?ANT2 pan-European research network. At SC07, Internet2, ESNet and G?ANT2 together with co-collaborators from GRNET, the national research and education network for Greece; HEAnet, the national research and education network for Ireland, and PIONIER, the national research and education network for Poland, will showcase the set up of a one Gigabit per second dynamic circuit using standard video transfer and file transfer applications. The applications will be initiated from the Internet2 SC booth and will leverage the Phoebus framework to access, and then dynamically set up, a separate point-to-point circuit between Reno, Nevada across the Internet2 DC network and the ESnet network, to the G?ANT2 network in Europe and then to the GRNET, HEAnet and PIONIER networks respectively. The applications are anticipated to transfer approximately seven gigabytes of data, the amount of data stored on a standard movie DVD, in one minute. As a framework and protocol for high-performance optical networks, Phoebus works to transparently split the end-to-end network path into distinct segments at specific adaption points, typically located at backbone ingress and egress points. Phoebus then works to minimize the impact of packet loss and latency by finding and creating the best network path for the specific application from each adaption point. Because of its architecture, many applications can begin to utilize Phoebus and the DC Network with no modification because of its ability to transparently authenticate and redirect the application to the circuit network via a Phoebus Gateway. Because of its inherent ability to find and enable the best possible end to end network path, Phoebus will be used in a SC07 Bandwidth Challenge submission to showcase its ability to maximize the performance of a 10 Gbps connection between Reno and CERN in Geneva, Switzerland. The challenge submission will use data related to the Large Hadron Collider (LHC) experimentation to showcase how Phoebus can support researchers utilizing high speed networks to participate in this bandwidth-intensive worldwide project. Phoebus will work to split the network path into distinct segments at specific adaptation points to optimize the performance of each segment thereby maximizing performance on the entire end to end path. write your comments about the article :: © 2007 Networking News :: home page |
