Here again we see the same elements as in the previous two figures, this time including the same pattern of data packets as in figure 9.11. Here, data packets in R1 have been separated into groups: dark blue packets on top and light blue packets on bottom. The dark blue packets bear black stripes, while the light blue packets bear gray stripes. The dark blue packets are labeled "1.0 Mbps logical link," while the light blue packets are labeled "0.5 Mbps logical link." Data packets continue to their destinations with their respective stripes.
