Flooding Flooding is often used in a local network to update path state information. To limit the number of transmissions, two rules are observed during flooding: the node does not relay the packet back to the sender; the node only relays the packet to its neighbor once. Consider the network topology in Figure 8.28. Assuming the transmission along each link takes time T, following the format given in Table 8.4, describe the network activity for the flooding initiated at node A. Assuming that point-to-point transmission is used, in other words no broadcasting, find the total number of transmissions that have occurred during the flooding.
