Ensuring QoS in Professional Audio Networks Which Use IEEE 1394b
The calculation of the bandwidth available, the latency of audio and control data and making sure the correct number of audio channels can be transmitted is of paramount importance to maintaining Quality of Service (QoS) in an audio network. QoS is very important in professional audio networks where audio needs to be delivered accurately to various nodes on the network. Firewire (IEEE 1394) is one technology which is used in these networks. Due to the limitation of cable length in IEEE 1394a and the improvements in IEEE 1394b, IEEE 1394b needs to be used. By performing calculations to determine the relevant bandwidth and latencies in any given scenario, the audio engineer can ensure QoS in a professional audio network.
