A Live Production Network refers to the infrastructure used to transmit and manage real-time video, audio, and data streams for broadcasting or event production. It integrates high-bandwidth connectivity, low-latency switching, and synchronization across distributed systems. Such networks are essential for live television, sports, and remote collaboration environments. Advances in IP-based transmission and software-defined networking have improved scalability and reliability. Research in this area enhances performance for next-generation media workflows.
We report the first trial of network tomography over a live network in a multi-domain environment. We visualize end-to-end optical powers along multiple routes across multiple domains solely from a commercial B00G transponder, enabling performance bottleneck localization, power and routing optimization, and lightpath provisioning.
