Advanced Quality of Service (QoS)

The IP Packet Processor incorporates multi-level QoS to ensure the highest quality of service
with minimal jitter and latency for real-time traffic, priority treatment of mission critical applications
and maximum bandwidth efficiency.
The supported modes of QoS are:
DiffServ – Industry-standard method of providing QoS, enabling seamless co-existence
in networks that implement DiffServ
Max/Priority – Provides multi-level traffic prioritization with the ability to limit maximum
traffic per priority class
Min/Max – Provides a Committed Information Rate (CIR) to each user-defined class of
traffic with the ability to allow a higher burstable rate depending on availability
When using rule-based QoS, you can configure up to 32 different rules based on:
Source IP address and subnet mask
Destination IP address and subnet mask
Source Port
Destination Port
Protocols (well known)
Priority
