Mutlicast routing - A to the others; others to A
I am wondering how to develop a solution to establish something like a conference talking between some network voice devices.
The scheme is as described:
A --------------> C
When A speaks, everyone in the network needs to receive the packets.
But when B,C or D speaks, the packets must reach only A.
waiting for your suggestions.
A, B, C, and D are simply embedded devices with TCP/IP stack. I do not know even if they support multicast addressing.
