15.2. Explain the difference between a wideband network and a broadband network. In network terminology, bandwidth is usually given in terms of bit rate, while in radio systems bandwidth is given in terms of frequency. Show how these concepts are connected. 15.3. Explain briefly what is meant by a network protocol. By referring to any of the standard publications showing the open systems interconnection (OSI) model, show how the ATM layer model, of Fig. 15.2, relates to the OSI model. (A comprehensive description of the OSI model can be found on the web site of Wikipedia, the free encyclopedia). 15.4. Describe briefly the difference between synchronous and asynchronous transfer modes. One author (Ramteke, 1994) points out that synchronous transmission mode (STM) uses asynchronous multiplexing, and ATM is transmitted using synchronous multiplexing (SONET). Explain how this is.

15.5. Describe the different types of interfaces and their functions in an ATM network. 15.6. With a BER of 10 8 the probability of a cell being discarded is about 10 13 20 and the probability of cells with undetected errors getting through is about 10 (Goralski, 1995, p. 140). On average, how many cells would be transmitted before a discard occurs Is the probability of a cell with undetected errors getting through of any concern 15.7. Describe briefly the difference between a ATM digital cross connect switch, and an ATM switch. 15.8. Describe briefly the difference between permanent virtual circuits and switched virtual circuits. 15.9. Explain what is meant by bandwidth on demand and how this is achieved in ATM. 15.10. A single user makes use of all the cells in an ATM transmission at a speed of 50 Mbps. What is the payload bandwidth 15.11. An ATM system transmits 8000 frames per second with a maximum of 10 cells per frame. What is the speed of the link 15.12. What type of signals are sensitive to variations in cell delay, and how does ATM accommodate these signals 15.13. State the essential differences between the five classes of service offered with ATM, and the applications for which each class would be used. What is meant by quality of service 15.14. What are the main technical parameters used in measuring ATM performance 15.15. Discuss briefly the main problems encountered in incorporating satellite links in ATM networks, and the steps taken to overcome these. 15.16. Explain what is meant by a bent pipe system in connection with satellite communications. 15.17. Describe the main distinguishing features between satellite relay, satellite access, and satellite interconnect, in connection with ATM over satellite. 15.18. What are the main advantages and disadvantages in using LEO satellites compared with GEO satellites in ATM networks 15.19. Write brief notes on the Internet and the WWW showing the relationship between them.

15.20. Describe the layered architecture that applies to networks, and indicate which of these layers contain (a) the IP and (b) the TCP. Explain what is meant by protocol. 15.21. Describe how connectionless and connection-oriented layers differ. 15.22. Describe what is meant by a packet in the different layers of a network. 15.23. Binary transmission occurs at a rate of 5000 bytes per second. What is this in bits per second 15.24. Binary transmission occurs at a rate of 25 kilobytes per second. What is this in kilobits per second 15.25. Binary transmission occurs at a rate of 30 megabytes per second. What is this in megabits per second 15.26. What is meant by a virtual link in a network 15.27. Define and explain what is meant by (a) receive window, (b) send window, and (c) timeout with reference to the Internet. 15.28. Explain what is meant by congestion and slow start in relation to Internet traffic. 15.29. In the early days of the Internet, Internet traffic could be sent over satellite links without any particular difficulty. State briefly the changes that have taken place that introduce difficulties and that require special attention. 15.30. Explain what is meant by RTT. Given that the uplink range to a satellite is 38,000 km and the downlink range is 40,000 km, calculate the RTT. 15.31. The overall bandwidth for a satellite link is 36 MHz, and the filtering is raised-cosine with a rolloff factor of 0.2. BPSK modulation is used. The range to the satellite is 39,000 km in both directions. Calculate the size of the largest packet that could be in transit if the BDP was the limiting factor. Assume that the RTT is equal to the space propagation delay. 15.32. A LEO satellite is used for Internet transmissions. The orbit can be assumed circular at an altitude of 800 km. Assuming that the minimum usable angle of elevation of the satellite is 10 (the angle above the horizon), calculate the approximate values of maximum and minimum RTTs. A spherical earth of uniform mass and radius of 6371 km may be assumed. 15.33. Repeat Prob. 15.32 for a circular MEO at altitude 20,000 km. 15.34. Briefly discuss the enhancements covered in RFC-2488 and how these might improve the performance of Internet traffic over satellite links.
