Pacific Quay has a core network with separately routed domains for users, television playout, radio production, post production, and a digital library. The fully converged network uses common hardware and protects core broadcast functions. It has a high bandwidth 40Gbps core with edge access switches connecting 22 hub rooms. Integration of different file formats, codecs, audio formats, metadata, and protocols between real-time and non-real-time systems presents challenges that require mapping schemas and determining if coupling is direct or loose. Questions can be directed to Brendan Mallon.
