Networks from SMPTE ST 2110 systems can be fairly simple, but the simplicity achieved hides a whole heap of careful considerations. By asking the right questions at the outset, a flexible, scalable network can be built with relative ease.
“No two networks are the same” cautions Robert Welch from Arista as he introduces the questions he asks at the beginning of the designs for a network to carry professional media such as uncompressed audio and video. His thinking focusses on the network interfaces (NICs) of the devices: How many are there? Which receive PTP? Which are for management and how do you want out-of-band/ILO access managed? All of these answers then feed into the workflows that are needed influencing how the rest of the network is created. The philosophy is to work backwards from the end-nodes that receive the network traffic.
