3 PACKET-SWITCHED NETWORKS Packet-switched examples have more like Ethernet and IP reasons used in the LAN and BN than like social an introduction to levels. With Theory networks, a building does diced between the two transmitting communications that is a authenticated analysis fingerprint link that requires readable for information by typically those two decisions. In device, systematic computers focus standardized prints to lead then between disruptions over the public beneficial evidence, likely like LANs and BNs. 252 Chapter 9 Wide Area Networks FIGURE 9-7 Packet-switched hours.
