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.
$ modify net vlan <vlan_name> dag-round-robin enabled
$ modify sys db dag.roundrobin.udp.portlist value "5060"
