Round Robin DAG
(RR-DAG)
RR-DAG was designed to overcome the low entropy limitations of
Default DAG and SP-Dag; although for UDP only. Furthermore, RR-DAG is hardware only
and can't be used in a VE. Round Robin DAG distributes traffic by sending each
consecutive packet to a different TMM. It does not rely on the IP address, or source
port, of the client. The Round Robin DAG is configured on a per-VLAN
basis.
SIP Specific
Requirements
- Immediate timeout must be set on the UDP Profile
Key
Points
- UDP Only
- Requires hardware (not an option in VE)
- Sends each consecutive packet to a different TMM.
