Quality of Service (QoS) is important when transmitting high bandwidth audio and
video information. QoS can be measured and guaranteed in terms of:
• Average delay between packets
• Variation in delay (jitter)
• Transmission error rate
DiffServ and Precedence are the two QoS methods supported by the RMX. These
methods differ in the way the packet’s priority is encoded in the packet header.
The RMX’s implementation of QoS is defined per Network Service, not per endpoint.

The routers must support QoS in order for IP packets to get higher priority.
