Hello networking,
I was studying multicast a couple of years back because I wanted to test my knowledge of CCIE and I have a couple of major questions.
Since multicast is basically like tuning your TV/radio to a channel, why are there multicast TCP streams? Its not like your TV will request the frame from the broadcasting channel.
In unicast, in order to have more than one device listening to a single IP, you need a NAT box (firewall/load-balancer). In multicast you can have more than one device stream on the same multicast IP but on a different port. How is this possible?
