4. Link layer multiple access protocols [8 points]. We studied a number of multiple access protocols in this course, including (1) TDMA, (2) CSMA, (3) Slotted Aloha and (4) Token passing. 1) Suppose you were charged with putting together a LAN to support IP telephony (only) and that multiple users may want to carry on a phone call at the same time. Recall that IP telephony digitizes and packetizes voice at a constant bit rate when a user is making an IP phone call. How well suited are these four protocols for this scenario? o Protocol: TDMA - suited? (yes/no) o Protocol: CSMA - suited? (yes/no) o Protocol: slotted Aloha - suited? (yes/no). o Protocol: Token passing - suited? (yes/no)
