Abstract
Provided are mechanisms for improving bandwidth for non-essential data on deterministic aircraft data networks (ADNs) such as ARINC 664 networks. A switch such as an ARINC 664 switch maintains rate constrains on one or more priority levels of traffic while releasing rate constraints on low priority traffic. Low priority traffic can be received at an ARINC 664 switch at rates allowed by an Ethernet physical layer. However, low priority, non-rate constrained traffic is transmitted only when there are no other scheduled messages to send. Low priority traffic can consume all available bandwidth whenever there is slack time. A switch can further be separated into zones including a standard rate constrained zone as well as a rate unconstrained zone. Internal or external cross-links can be provided between the zones for any data that needs to be transferred between zones.
