Section B: Wired Networks. Section C: Wireless Networks. Section D: Using LANs. Section E: Security Through Encryption. Goals. You will write a program that implements a simple Ethernet bridge. The bridge must forward packets from hosts. Thus, you’ll need to maintain a forwarding table. The network may have loops. Thus, you must implement the spanning tree protocol. networks. WLAN. . is a wireless network that links many devices within a limited area such as a home, school, university, or office building. . WLANs give users . the ability to move around within the local coverage area and still be connected to the network. . Approach . 7. th. edition . Jim Kurose, Keith Ross. Pearson/Addison Wesley.
