| What's the difference between multicast, broadcast and unicast function in Clonezilla SE ? |
This description was modified from the doc of udpcast, which is used in Clonezilla for multicast or broadcast:
The multicast function allows sending the data only to those receivers that requested it. Ethernet cards of machines which don't participate in the transmission automatically block out the packets at the hardware level. Moreover, network switches are able to selectively transmit the packets only to those network ports to which receivers are connected. Both features thus allow a much more efficient operation than broadcast.
Therefore if your switch does not block multicast packets, it's better to use multicast function.
