Internet2’s HOPI Project Helps Provide Dynamic Provisioning of Light Paths for Radio Astronomy
The emergence of a new generation of connection-oriented service paradigms, dubbed “light paths,” is enabling new capabilities within the global advanced networking community.

October 1, 2005 - During iGrid 2005, Internet2 was one of several international collaborators that demonstrated how network services can be provisioned in an automated fashion in support of an application - with flexibility, intelligent path computation, and with features such as advanced scheduling and integrated security. The demo “Dynamic Provisioning of Light Path Services for Radio Astronomy Applications” incorporated Internet2’s HOPI testbed and the NSF DRAGON testbed to deploy a multi-domain GMPLS dynamic and inter-domain control plane. For the iGrid demo, light paths were established across several international network facilities to reach telescopes in Sweden, the Netherlands, Japan, and the United Kingdom. These international sites were assembled dynamically, across HOPI and DRAGON, to create an “application specific network topology“ for the real-time, radio astronomy (e-VLBI or, electronic Very Long Baseline Interferometry) application.
