Example text
You will examine the given design and identify and correct any design errors. You will then cable the network, configure the hosts, and load configurations onto the router. Finally, you will troubleshoot the connectivity problems to determine where the errors are occurring and correct them using the appropriate commands. When all errors have been corrected, each host should be able to communicate with all other configured network elements and with the other host. qxp 8/25/09 10:57 AM Page 25 Chapter 1: LAN Design Refer to Packet Tracer Activity for this chapter 25 The configuration contains design and configuration errors that conflict with stated requirements and prevent end-to-end communication.
Broadcast: Communication in which a frame is sent from one address to all other addresses. In this case, there is just one sender, but the information is sent to all connected receivers. Broadcast transmission is essential when sending the same message to all devices on the LAN. An example of a broadcast transmission is the address resolution query that the address resolution protocol (ARP) sends to all computers on a LAN. Multicast: Communication in which a frame is sent to a specific group of devices or clients.
Software applications are becoming richer in their functionality and are requiring more and more bandwidth. Desktop publishing, engineering design, video on demand (VoD), electronic learning (e-learning), and streaming video all require considerable processing power and speed. LAN Segmentation LANs are segmented into a number of smaller collision and broadcast domains using routers and switches. Previously, bridges were used, but this type of network equipment is rarely seen in a modern switched LAN.
