NOTE — Data to be transmitted is buffered in a queue and transmitted when its device’s transmission slot
is available. If the application has multiple traffic types, such as critical control/safety packets or best­effort
packets, the critical packets can be prioritized via a filter. Packets matching the filter will be buffered in the
corresponding priority queue and sent prior to packets in the ”Best Effort” queue. If no prioritized traffic is
set, all data is treated as ”Best Effort”.

NOTE — If Handover is enabled, drop rule for anchor multicast traffic is automatically added based on
”Backbone IP” setting (see Section 5.3.4). This rule will not be added automatically if it is already manually
entered.

Queues Sizes
ATTENTION — This setting needs changes only in very specific scenarios. Proceed with caution!
!
The queues in EchoRing are equally sized by default. In special cases, e.g. with very high
traffic load in one priority class compared to the others, it may be necessary to customize
the queue sizes to ensure no packets are lost.
EchoRing will allocate the queue sizes automatically by default, or if the entries are not
specified (all entries 0).
To customize queue sizes, queue sizes need to be configured for all priorities that have been
assigned in the Traffic Filter section. If possible, the available buffers will be assigned as
specified, any additional buffers will be distributed equally among all queues.
