Abstract
Several NMP categories have been described in the previous chapter. The most technical demanding approaches are of special interest in this book. Low-latency audio data transfer through networking is not easily accomplished. Many research efforts generally rely on dedicated bandwidth networks for audio (and often video) transmission, such as the Internet2 in the US and the GEANT network in Europe. These are fiber networks connecting selected institutions (such as Universities) with high bandwidth (generally \(>\) \(1\) Gbit) and low latency, by manually routing the signals, reducing the number of switches in the path, and assigning a high QoS to the audio/video signals. Reference implementations of high-quality and low-latency NMPs are based on such networks and experimental software has been developed by several research groups. Nonetheless, NMP practice still requires effort in its development, planning, and deployment phases and all technical issues must be addressed with care. This chapter of the book is devoted by introducing all the most relevant technical issues, giving a basic understanding to a broad audience ranging from musicians with a basic scientific training to audio engineers.
