HIGH SPEED WIDE-AREA NETWORKS

HIGH SPEED WIDE-AREA NETWORKS The most widely used data communication service is Frame Relay, which was developed as part of the ISDN project. It can be used in" rel="nofollow">in private and public network configurations. Frame Relay uses variable size pockets or frames, and the process is simpler than X.25. Data rates of 2 Megabits can be achieved. Accordin" rel="nofollow">ing to Forouzan (2007, p. 453), Frame Relay provides permanent virtual circuits and switched virtual circuits. For example, Frame Relay network can be connected to the Internet and in" rel="nofollow">internal LANs and WANs through the use of routers. Frame Relay WANs can be used as one lin" rel="nofollow">ink in" rel="nofollow">in the global Internet.

Use the hex converter http://www.bin" rel="nofollow">inaryhexconverter.com/ for the followin" rel="nofollow">ing exercises. Submit the assignment answers in" rel="nofollow">in a 2- to 3-page Word document. The address field of a Frame Relay frame is 1011000000010111. What is the DLCI in" rel="nofollow">in decimal? What is the DLCI in" rel="nofollow">in bin" rel="nofollow">inary? The address field of a Frame Relay frame is 101100000101001. Is this valid? Fin" rel="nofollow">ind the DLCI value if the first 3 bytes received is 7C 74 El in" rel="nofollow">in hexadecimal. Fin" rel="nofollow">ind the value of the 2-byte address field in" rel="nofollow">in hexadecimal if the DLCI is 178. Assume no congestion. How does Frame Relay differ from X.25? What is SONET and SONET/SDH? What are the various devices that can in" rel="nofollow">interconnect to SONET?
