Figure 83 Ports example
To transmit a burst from A to B, the Transmission Port field is equal to 9.
To transmit a burst from B to A, the Transmission Port field is equal to 15.
In B the Port Solver Table has the following entry:
• MAC address equal to A MAC address
• Local Port equal to 15.
• First Remote Port equal to 9.
In A the Port Solver Table has the following entry:
• MAC address equal to B MAC address
• Local Port equal to 9.
• First Remote Port equal to 15.
The first remote port exchange process is described in section 9.1.4.2.
9.1.4.1.2 Multicast Communication example
The second remote port is intended to support native multicast using BPL by means of identify a physical unique
link that will have its own tonemap and particular management, as described in section 9.1.2.1
In the following draw, node A has three links stablished. First one is a unicast link with node B, second another
unicast link with node C and finally, a multicast link with nodes B and C. The local reference in node A for each of
the links is its assigned Local Port, in this case 9, 10 and 12 respectively.
