Re: [Udpcast] multicast address to listen on

Hi,

Does udp-sender include the Ethernet multicast address for the receiver to listen on in HELLO messages ?

Yes, this is indeed transmitted in the HELLO message

There seems not to be any other mechanism to pass this information around (?)

Thanks.

... however, in the event where only one receiver connects, the sender directly sends it to its unicast address. So, in order to be prepared, the receiver has to listen to both addresses (mcast address from HELLO, and unicast address)

Indeed, the sender cannot yet include the unicast address in the HELLO packet, because at that stage of the protocol, it is not yet known how many receivers there will be.
