- Traffic transmission mode:
- "Multicast" - conventional mode that uses modulation one step lower than the lowest modulation among the traffic receivers when transmitting the "multicast/broadcast" frames. In the case of "multicast" streams information from "IGMP Snooping" module is used to obtain a list of subscribers. Consequently, the list of all connected sector clients is used for the "broadcast" traffic.
- Transformation of "Multicast" to "Unicast". In case two or more clients are assigned to the same "multicast" stream a copy of source stream will be sent to each of them in the "Unicast" mode.
- "Unicast 2", "Unicast 3", "Unicast 4", "Unicast 5" - the number of subscribers limitation. Conventional "Multicast" mode will be used when the number is exceeded.
- "Unicast All" - transformation is always executed.
Transformation to "Unicast" requires memory data copying that increases CPU load. Besides, the use of "Unicast" streams increases the volume of transmitted traffic proportional to the number of subscribers and reduces the sector available throughput.

"Unicast 3" mode is set by default. |

Transformation of "Multicast" to "Unicast" via CLI is described in the section "mint command". |
