Presentation description: In the era of crowdsourcing and omnipresent networking the performing arts area of research, and in particular the theatre, will suffer a huge transformation to stay up to date and make a proficient use of the immense potentials of the new technologies. The new paradigm introduced with ultra high speed networks growing both in commercial and research frameworks will force a redesign of the performing space that will be something else from theatre as we know it and will make William Shakespeare's "all the world's a stage" a feasible scenario also for real-time performances. Given this premise we investigated in a sinergy with a renowned experimental-theatre director, namely G.B.Corsetti, the possibilities opened by the physical fragmentation of the stage space. This experiment started in 2015 and drove GARR and Corsetti's team of actors and video makers to embrace a new form of theatrical approach that resulted recently in a professional performance: "il Ratto di Europa" staged at REF16 (Roma Europa Festival 2016). The overall process of finding a technical solution to a "real life performative problem" brought the GARR team to put together a so called distrActive (distributed and interActive) technology that allowed Corsetti's team to couple their creative needs with the optical fibers infrastructure own by GARR through an hack of a commercially available hardware and to create a geo-distributed performance. The technology is an absolute innovation in the field of performing arts and the system has been designed as much general purpose and usable as possible. The architecture aimed to: ● ● ● usability: the use of a remote or local camera on the stage space is almost equivalent from the director’s point of view speed: the latency introduced by a remote actor has been kept to few ms (far beyond the latency of a normal camera used in these setups and far beyond the human perception) portability: given an optical fiber network connection in the proximity (50-80km) it's in principle possible to remotely use up to 16 video channels and 64 analog audio channels (at the state of the art) on a single fiber couple Aiming to a broad diffusion in a field that is clearly not a high-budget one there has been a certain effort also in terms of the ratio between costs and performances and the choice of the hardware (given the optical fibers mesh and the possibility to configure optical paths on that so to connect different points of the infrastructure) has been carefully chosen so to minimize the expenses. This is an obvious extension and a different approach than the LOLA established project (also strongly driven by GARR) which uses the so called IP level (or L3) of the ISO OSI stack and coupling and mixing of the two technologies can be foreseen to extend the usability to places where a direct optical connection would be not feasible. The presentation aims to show the details of all the phases of the project and the finalized solution that we wish to export towards the community. We do not want to bring only an extremely successful use case to the attention of the TNC public, but to address the question if a dematerialization of the stage space in the form of a "network of c-theatres" is a feasible scenario, like the one we had with the distribution network for the electricity after Edison or the distribution of computing which we witness nowadays with cloud-ification of computing and delocalization of storage resources. The pros and contras of using Layer 2 instead of Layer 3 deserve attention. A mixed scenario (of L2 + L3) can work in synergy with LOLA (ref:http://www.conservatorio.trieste.it/art/ricerca/progetto-lola-low-latency ) also needs to be carefully evaluated.
