Requirement

Standard Settings

Quality of ServiceWith strict priority

DiffServ To make sure PTP synchronization packets and audio packets get priority over control packets.OMNEO uses QoS on IP level to avoid synchronization and audio problems on busy networks. Although the system does work without problems on relatively quiet networks (< 10% network load) it is important to configure your network switches correctly.The used QoS is Differentiated Services or DiffServ, which is part of the Type of Services field (ToS) in the IP header. For more details on DiffServ & IP header, see Wikipedia.

Packet forwarding in HW per port >1.2Mpps

n.a. If SW is responsible for packet switching, this would result in variable latency which is unacceptable.

Disable EEE

IEEE 802.3az Most implementations of EEE cause problems because of implementation flaws. A good implementation should work, but does not save energy since the PTP synchronization avoids this. Therefore, EEE must always be disabled.
