c) Every repeater sends each packet only once. However, receivers can receive

each packet several times (sent by different repeaters), if there are packets of

different content in the network temporally close to each other. Thus, on the side

of the receiving device, a mechanism shall be implemented that detects and ﬁlters

double packets.

13.2 Example network

Figure 7: Example network

In the example network shown above, the goal is to send a packet from device 1 to 5. Without

the repeater devices, this would be impossible. The steps are as follows:

1. Sender 1 sends a packet.

a) Repeater 2 and 3 receive and accept it at the same time.

2. Device 2 and 3 delay the packet.

a) Repeater 3 sends the packet.

i. Sender 1 and 6 do not accept it, since their addresses are wrong (unequal 5).
