Pasian ( 1,2 ) ( 1 ) INAF – Information Systems Unit, ( 2 ) INAF – Osservatorio Astronomico di Trieste, ( 3 ) Sincrotrone Trieste SCpA, ( 4 ) University of Trieste Lightnet, the new MAN (Metropolitan Area Network) in Trieste dedicated to research is in production since June It is based on Fiber Optic Rings able to bring up to 32 wavelengths (λ), each of them of 1 Gbps given the technology currently chosen for the apparata. Institutes own one or more λs, each dedicated to a specific purpose (connections to the GARR POP, intra-Lightnet connections, intra-Institute connections, specific multi-Institution services or applications). One of the 1 Gb λs of Lightnet is dedicated to an experimental project set up in 2005 aimed at exchanging know-how and at creating a stable Metropolitan Grid Infrastructure (MGI) for the benefit of scientific Institutions in Trieste. During this experimental phase all Grid tools and services necessary to make the infrastructure self-consistent were set up. Scientific communities contributed with a pool of gridified applications. Thanks to the advent of Lightnet, the bottleneck represented by the limited bandwidth available for inter-Institute connections was removed, so operations and further expansions of are now possible.
