“…In a later work [3], we extended existing results by providing a more sophisticated prototype for wide area networks. In these evaluation setups within the high capacity German Research Network (DFN), we showed that NMP sessions could be realized with network distances up to 500 km [3] roundtrip. However, to deploy NMP in commercial settings, experiments on real-world access networks are necessary.…”

Network-centric Music Performance (NMP) enables Internet-based multiparty music performance through cyberspace. Our goal is to support real-time distributed natural audio delivery over the network, using audio compression schemes with exceptional audio quality. Among many challenges, a tight delay bound between the production and perception of the audio is a dominant requirement. The demo video shows a recorded session of a live network-centric music performance demonstration involving a SDSL access network. It demonstrates that musicians can play together smoothly on a virtual stage provided by NMP. Beyond our previous work of realizing NMP in local and wide area research networks, this is the first time NMP has been enabled with a commercially available synchronous DSL access network. The positive ratings by the musicians confirm that NMP is ready for large-scale commercial deployment once such access technology is widely available and affordable to the end users.

“…Types of musical interaction (presented by Team FIBRUS) from Á. Barbosa [2] In this scenario, musicians will be capable of rehearsing remotely only if located in places no farther than approximately 20-50 ms in latency [3]. In the OFCity Challenge, Team FIBRUS tested this scenario in a transatlantic Remote Jamming session between Pisa Italy and Dallas Texas US, as depicted in Fig.…”

The drive towards ubiquitous communications has long been encompassed by the concept of a connected or smart city. The idea that data transfer and real-time data analysis can enhance the quality of life for urban inhabitants is compelling, and one can easily envision the provision of exciting new services and applications that such an information-driven city could provide. The challenge in achieving a truly smart city stems largely from communications technologies -fixed line, wireless, backhaul, and fronthaul -and how these are combined to provide fast, reliable, and secure communications coverage.Here, we report on the key observations from the Connected OFCity Challenge competition, held at the Optical Fiber Communications Conference (OFC) 2017, which addressed the fixed and wireless access network requirements for smart cities. It is shown that, from a technological perspective, future optical networks will be capable of securely supporting extremely low-latency and high bandwidth applications. However, as shown by using a Networked Music Performance as a particularly challenging example application, how readily this is achieved will depend on the interplay between wired and wireless access services.

“…In one case [58] packet loss recovery techniques are explicitly avoided, to further decrease network latency; in such a case, the network is supposed to be ''error free''. Some frameworks [82], [86], [93], [104], [108] build data loss management on top of the RTP/RTCP transport protocol [115], taking advantage of the timestamps and sequence numbers included in each RTP packet header. Note that RTP also defines a specific payload format dedicated to MIDI data [116].…”

Networked music performance (NMP) is a potential game changer among Internet applications, as it aims at revolutionizing the traditional concept of musical interaction by enabling remote musicians to interact and perform together through a telecommunication network. Ensuring realistic performance conditions, however, constitutes a significant engineering challenge due to the extremely strict requirements in terms of network delay and audio quality, which are needed to maintain a stable tempo, a satisfying synchronicity between performers and, more generally, a high-quality interaction experience. In this paper, we offer a review of the psycho-perceptual studies conducted in the past decade, aimed at identifying latency tolerance thresholds for synchronous real-time musical performance. We also provide an overview of hardware/software enabling technologies for NMP, with a particular emphasis on system architecture paradigms, networking configurations, and applications to real use cases.
