LAN Topologies - TechTarget

C H A P T E R2 LAN TopologiesThe application in use, such as multimedia, database updates, e-mail, or file and print sharing, generally determines the type of data transmissions fit into one of three categories: Unicast Multicast BroadcastUnicast With unicast transmissions, a single packet is sent from the source to a destination on a network. The source-node addresses the packet by using the network address of the destination node. The packet is then forwarded to the destination network and the network passes the packet to its final destination. Figure 2-1 is an example of a unicast 2-1 Unicast Page 13 Wednesday, November 14, 2001 3:28 PM14 Chapter 2: LAN TopologiesMulticastWith a multicast transmission, a single data packet is copied and forwarded to a specific subset of nodes on the network. The source node addresses the packet by using a multicast address. For example, the TCP/IP suite uses to The packet is then sent to the network, which makes copies of the packet and sends a copy to each segment with a node that is part of the multicast address.

network termination points. This single cable segment lends itself to being a single point of failure. If the cable is broken, no LAN station will have connectivity or the ability to transmit and receive.
